Introduction

The Dell UltraSharp range has been one of the most popular ranges of displays for over 10 years now. Dell seem to update their models and add new options to the range every year or two and we've reached the time where they've decided to refresh most of their popular models. In May we reviewed the new U2417HJ, which was one of three models replacing the very popular U2414H from 2013/14. In a moment we will elaborate on the three new models and how they differ slightly - the U2417H, U2417HJ and U2417HA. After reviewing the U2417HJ version, we were keen to also take a look at the "normal" U2417H which has a slightly different design, spec and feature set to the HJ model. The HA model is exactly the same as this H model, just with an arm mount instead of the stand. So by reviewing the H model here, we have covered off all 3 versions of this new model nicely.

This screen is 23.8" in size like its predecessor, with the H signifying it is 16:9 aspect ratio - offering a 1920 x 1080 resolution. Much of the design, spec and feature set remains quite similar to the older U2414H model, but we will make comparisons with the U2414H throughout the course of the review.

As we've mentioned, there are actually 3 different versions of the new U2417H display, all slightly different in terms of features and extras, and with slightly differences with the underlying panel. All 3 versions technically replace the U2414H screen, but there are a few differences you should be aware of before making a decision.

The three slightly different versions of the U2417H are:

U2417HJ - This is the model sent to us first of all for testing and already reviewed in May. It is the most similar in design to the old U2414H. It has the same video inputs as the U2414H, including DP, Mini DP and 2x HDMI. The main difference on the new U2417HJ is that it has a wireless charging function built in to the stand for Qi/PMA compliant devices. The stand is the same design we've seen from previous UltraSharp models including the previous U2414H from a couple of years ago. It has a light silver colour used for the stand and base, and an elongated cable tidy hole in the back. The only difference with the stand is the integrated wireless charging point and small LED charging light.

The screens bezel dimensions and appearance are very similar to the old U2414H. The back of the screen is a matte black colour entirely like the U2414H was. There are 4 USB 3.0 ports on this model, 3 on the underside with the other connections, and one on the back (visible in the lower right area above) which also has charging capabilities, again the same as the U2414H. Even the OSD menu is identical and has not been updated with any new options. Dell have forgotten to update the model name in the OSD software so it still reads 'U2414H' in fact. Some people have labelled the U2417HJ as a re-packaged U2414H, but although the design and features remain very similar, the underlying panel has been changed though compared with the old U2414H, moving from an LG.Display IPS panel to a Samsung PLS equivalent. This panel has a 96% sRGB coverage according to the spec and comes factory calibrated to offer a dE <4. So the main changes from the U2414H are the different underlying panel, and the charging function built in to the stand.

U2417H - the "normal" U2417H is more different to the old U2414H and is the model we are now reviewing here. It has a four-side zero-bezel design, minimising the size of the lower bezel from the U2414H and U2417HJ models. It has a two colour toned back as shown in the pictures here (silver and black). The front of the stand and the base is also a darker silver colour like we had seen on the Dell S2716DG and U2717D recently, with a circular cable tidy hole in the back as shown above. There are 2x USB 3.0 ports located on the left hand edge of the screen at the bottom too (not on the HJ) for easy access, although there are still only 4 in total.

This H model is missing one HDMI connection and the wireless charging function compared with the HJ. It does have an updated OSD software though, including an additional response time setting in the OSD menu. The HJ model doesn't have a response time setting in the OSD menu although we've seen in the past that actually the 'normal' setting tends to be optimal anyway on models with an additional 'fast' option, so this extra setting probably isn't even missed on the HJ model. The underlying panel is slightly different to the HJ model. Again Dell have moved away from an LG.Display IPS panel from the U2414H and to a Samsung PLS equivalent. It is a different revision in the H model (LTM238HL04) compared with the HJ (LTM238HL01). This panel has a 99% sRGB coverage (vs 96% on the HJ's panel) and carries a factory calibration with dE <2 (vs dE <4 on the HJ model). We will make comparisons of the performance between the H model and the U2414H / U2417HJ displays throughout this review.

 

U2417HA - this model is basically the same as the U2417H, with the same underlying panel, four side zero-frame design, two coloured back, 2x USB ports on the left hand edge, additional response time setting in the OSD menu and one less HDMI connection than the U2417HJ model. The difference between this and the normal U2417H is that rather than a monitor stand, it is provided with a mounting arm as shown in the above pictures. So the performance and tests in this review also apply to the HA model.

Design and Ergonomics

 
Above: front view of the screen

The U2417H is part of Dell's 'Infinity Edge' designed UltraSharp range, much like the U2717D we also tested recently. This gives it a zero bezel design around all sides, including the bottom. There is a very thin bezel around all the edges giving it a sleek and clean design, ideal also for multi-screen set ups. The old U2414H and also the U2417HJ version have a zero bezel design along the sides and top, but a 15mm thick bezel along the bottom edge. This is the first 24" category model from Dell to offer a zero bezel design around all sides.

There is a very thin plastic edge measuring ~1mm around all 4 sides. This is an additional ~4.5mm inner panel border before the image starts along the sides and top (total of ~5.5mm black edges around the sides and top), and slightly wider at ~7.5mm along the bottom edge (total ~8.5mm border). Along the bottom edge the plastic bezel slopes away from you so it's not a flat edge like the sides and top (see some of the below images for a better idea). From a normal viewing position this slope cannot be seen though so the screen does look like it has a very thin border around all four sides.

There is a small silver Dell logo in the middle of the bottom panel border, seemingly stuck on to the front of the panel where the black border is. Along the bottom right hand sloping edge are the pressable OSD control buttons and power button in the right hand corner. These protrude out a little so you can just see them from a normal viewing position.

 


Above: back view and base. Click for larger versions

The back of the screen, stand and base are finished in a matte dark silver colour as shown above. There is a circular cable tidy hole in the back of the stand as you can see from the above images. The stand and base are the same design as the recently reviewed S2716DG gaming display, and the Infinity Edge U2717D and a move away from the lighter silver colours we have seen on previous 24" UltraSharp models including the U2414H before it. As a side note, the U2417HJ model retained the same design as the U2414H, so this H model is a re-design and change.


 
Above: full tilt range shown. Click for larger versions

The screen offers a full range of ergonomic adjustments. Tilt is smooth to move but a little stiff. It offers a good adjustment range as shown above.

 
Above: full height adjustment range shown. Click for larger versions

Height adjustment is also available with smooth movement which is a little easier to re-position than tilt. At the lowest setting the bottom edge of the screen is ~40mm from the top of the desk, and at maximum extension it is ~170mm. This gives a total adjustment range of ~130mm which is decent.

Side to side swivel is smooth but fairly stiff, sometimes resulting in the whole screen and base moving instead of just the screen shifting side to side and the base remaining stationary. Rotation is also offered but is stiff to use, although at least fairly useable on a screen this size. Overall the screen remained stable on the desk with minimal wobbling.

The materials were of a good standard and the build quality felt good as well. There was no audible noise from the screen, even when conducting specific tests which can often identify buzzing issues. The whole screen remained cool even during prolonged use as well which was pleasing.

 
Above: interface connections

The back of the screen features the interface connections as shown above. There are (from left to right) the power connection, HDMI, DisplayPort in, Mini DisplayPort, DisplayPort out, audio out, USB upstream and 2x USB 3.0 downstream. The lack of DVI or VGA connections may be limiting for some older systems, but most modern devices and graphics cards should be offering HDMI or DisplayPort nowadays.

Two additional easy-access USB 3.0 ports are provided on the left hand side of the screen, with the bottom of the two having charging capabilities as well. We prefer the position of those on the side to them being on the back of the screen as they are on the HJ (1x port).



OSD Menu


Above: OSD control buttons on the bottom right hand corner. Click for larger version

The OSD menu is controlled from a series of 4 pressable buttons on the lower right hand edge of the front bezel as it slopes away from you. There is also a power button which has a small rectangular LED beneath it which glows white during operation and pulsates on and off (white) during standby. The HJ model was criticised a little as Dell had not updated the software since the U2414H, with all options remaining the same. In fact they didn't even change the monitor name in the menu and it still read "U2414H"! Here, on the H model they have updated the software in line with other recent UltraSharp screens like the U2717D for example.

Pressing any of the four buttons pops up a quick access menu as shown above. There are quick access options to get to the preset modes and input selection by default. These can be customised within the main OSD menu if you would prefer quick access to other settings as well.

    

As an example of what the quick launch option looks like when selected, the preset mode quick access menu is shown above.

The main menu is split in to 8 sections down the left hand side, with the options for each shown then on the right hand side. A couple of examples are shown above but most sections are self-explanatory. The 'display' section has the options for aspect ratio control and the response time setting as you can see.

We liked the new style and design of the OSD software on the U2417H and there were plenty of options and settings to play with. Navigation was a little tricky as the buttons are kind of tucked out of the way, and you have to keep drilling in to different options to get where you want, and then back out. We have gotten somewhat used to joystick controls on other modern screens which are easier to use.

 


Power Consumption

In terms of power consumption the manufacturer lists typical usage of 19.0W and <0.5W in standby mode. We carried out our normal tests to establish its power consumption ourselves.

We tested this ourselves and found that out of the box the screen used 18.4W at the default 75% brightness setting. At 100% brightness this increased a little to 22.4W. Additional power draw in the spec is related to having USB and SoundBar devices connected. Once calibrated the screen reached 15.0W consumption, and in standby it used only 0.6W. We have plotted these results below compared with other screens we have tested. The consumption is comparable to the previous U2414H model and HJ version of this screen as you might expect and a little less than the bigger sized screens and those with wide gamut LED backlights like the Dell U2413 for instance.

Panel Part and Colour Depth

The Dell U2417H features a Samsung LTM238HL04 PLS (IPS-type) technology panel which is capable of producing 16.7 million colours. This is achieved through a 6-bit+FRC colour depth as with most modern IPS-type panels of this size range. It should be noted that this is a move away from LG.Display for Dell as the old U2414H model featured an LG.Display IPS panel instead. They've moved this time to a Samsung PLS (IPS-type) panel with four-side borderless design. Note that the panel is slightly different in the U2417HJ model which has the LTM238HL01 panel from Samsung. See the U2417HJ review for testing of that version.

A note about PLS technology. This is Samsung's answer to LG.Display's very popular, and long-established IPS (In Plane Switching) technology. Testing of this technology has revealed that it is for all intents and purposes the same as IPS. Performance characteristics, features and specs are all pretty much identical. Samsung weren't allowed to simply call their technology IPS due to trademark issues, which is why they adopted their own new name of PLS. AU Optronics are the same with their AHVA panel tech, which is another IPS-clone. You will see pretty much all monitor manufacturers now simply use the term IPS, since it is so well known in the market, but underneath they may be using an IPS version from LG.Display, AU Optronics or Samsung potentially. People should not get concerned with the semantics here, which is why we will continually refer to this as an "IPS-type" panel throughout the review.

The panel part is confirmed when dismantling the screen as shown below.

Screen Coating

The screen coating is a light anti-glare (AG) offering. It isn't a semi-glossy coating, but it is light as seen on other modern IPS type panels. Thankfully it isn't a heavily grainy coating like some old IPS panels feature and is also lighter than modern TN Film panel coating. It retains its anti-glare properties to avoid too many unwanted reflections of a full glossy coating, but does not produce an too grainy or dirty an image that some thicker AG coatings can. No cross-hatching patterns were visible on the coating at all. The coating remains unchanged compared with the old U2414H model and is the same on the U2417HJ.


Backlight Type and Colour Gamut

The screen uses a White-LED (W-LED) backlight unit which is standard in today's market. This helps reduce power consumption compared with older CCFL backlight units and brings about some environmental benefits as well. The W-LED unit offers a standard colour gamut which is approximately equal to the sRGB colour space. Dell quote 99% coverage in their spec (slightly more than the 96% quoted on the U2417HJ). Anyone wanting to work with wider colour spaces would need to consider wide gamut CCFL screens or the newer range of GB-r-LED type (and similar) displays available now. If you want to read more about colour spaces and gamut then please have a read of our detailed article.


Backlight Dimming and Flicker

We tested the screen to establish the methods used to control backlight dimming. Our in depth article talks in more details about a common method used for this which is called Pulse Width Modulation (PWM). This in itself gives cause for concern to some users who have experienced eye strain, headaches and other symptoms as a result of the flickering backlight caused by this technology. We use a photosensor + oscilloscope system to measure backlight dimming control with a high level of accuracy and ease. These tests allow us to establish

1) Whether PWM is being used to control the backlight
2) The frequency and other characteristics at which this operates, if it is used
3) Whether a flicker may be introduced or potentially noticeable at certain settings

If PWM is used for backlight dimming, the higher the frequency, the less likely you are to see artefacts and flicker. The duty cycle (the time for which the backlight is on) is also important and the shorter the duty cycle, the more potential there is that you may see flicker. The other factor which can influence flicker is the amplitude of the PWM, measuring the difference in brightness output between the 'on' and 'off' states. Please remember that not every user would notice a flicker from a backlight using PWM, but it is something to be wary of. It is also a hard thing to quantify as it is very subjective when talking about whether a user may or may not experience the side effects.

Above scale = 1 horizontal grid = 5ms

At 100% brightness a constant voltage is applied to the backlight. As you reduce the brightness setting to dim the backlight a Direct Current (DC) method is used, as opposed to any form of PWM. This applies to all brightness settings from 100% down to 0%. The screen is flicker free as a result which is excellent news (as is the HJ model, and as was the U2414H before it).

Contrast Stability and Brightness

We wanted to see how much variance there was in the screens contrast as we adjusted the monitor setting for brightness. In theory, brightness and contrast are two independent parameters, and good contrast is a requirement regardless of the brightness adjustment. Unfortunately, such is not always the case in practice. We recorded the screens luminance and black depth at various OSD brightness settings, and calculated the contrast ratio from there. Graphics card settings were left at default with no ICC profile or calibration active. Tests were made using an X-rite i1 Display Pro colorimeter. It should be noted that we used the BasICColor calibration software here to record these, and so luminance at default settings may vary a little from the LaCie Blue Eye Pro report.

We conducted these tests in the default 'standard' preset mode. The brightness control gave us a very good range of adjustment. At the top end the maximum luminance reached 241 cd/m2 which was only a tad lower than the specified maximum brightness of 250 cd/m2 from the manufacturer. There was a decent 209 cd/m2 adjustment range in total, and so at the minimum setting you could reach down to a low luminance of 32 cd/m2. This should be more than adequate for those wanting to work in darkened room conditions with low ambient light. A setting of 47 in the OSD menu should return you a luminance of around 120 cd/m2 at default settings in this preset mode (standard). It should be noted that the brightness regulation is controlled without the need for Pulse Width Modulation, using a Direct Current (DC) method for all brightness settings between 100 and 0% and so the screen is flicker free.

We have plotted the luminance trend on the graph above. The screen behaves as it should in this regard, with a reduction in the luminance output of the screen controlled by the reduction in the OSD brightness setting. This is not quite a linear relationship as you can see, with the adjustments between 100 and 80 controlling a slightly steeper luminance range.

The average contrast ratio of the screen was excellent for an IPS panel at 1159:1. This was fairly stable across the brightness adjustment range as shown above with some fluctuation at the lower brightness adjustment end below 30%.



Testing Methodology

An important thing to consider for most users is how a screen will perform out of the box and with some basic manual adjustments. Since most users won't have access to hardware colorimeter tools, it is important to understand how the screen is going to perform in terms of colour accuracy for the average user.

We restored our graphics card to default settings and disabled any previously active ICC profiles and gamma corrections. The screen was tested at default factory settings using our new X-rite i1 Pro 2 Spectrophotometer combined with LaCie's Blue Eye Pro software suite. An X-rite i1 Display Pro colorimeter was also used to verify the black point and contrast ratio since the i1 Pro 2 spectrophotometer is less reliable at the darker end.

Targets for these tests are as follows:

  • CIE Diagram - validates the colour space covered by the monitors backlighting in a 2D view, with the black triangle representing the displays gamut, and other reference colour spaces shown for comparison

  • Gamma - we aim for 2.2 which is the default for computer monitors

  • Colour temperature / white point - we aim for 6500k which is the temperature of daylight

  • Luminance - we aim for 120 cd/m2, which is the recommended luminance for LCD monitors in normal lighting conditions

  • Black depth - we aim for as low as possible to maximise shadow detail and to offer us the best contrast ratio

  • Contrast ratio - we aim for as high as possible. Any dynamic contrast ratio controls are turned off here if present

  • dE average / maximum - as low as possible. If DeltaE >3, the color displayed is significantly different from the theoretical one, meaning that the difference will be perceptible to the viewer. If DeltaE <2, LaCie considers the calibration a success; there remains a slight difference, but it is barely undetectable. If DeltaE < 1, the color fidelity is excellent.

Initially out of the box the screen was set in the default standard preset mode. Despite the high 75% brightness setting out of the box the screen didn't look overly bright which is quite unusual, and you don't need to lower it much to get a comfortable setting for every day use. You could tell the screen was using a standard gamut backlight as well with the naked eye.

 

We went ahead and measured the default state with the i1 Pro. The CIE diagram on the left of the image confirms that the monitors colour gamut (black triangle) is fairly equal to the sRGB colour space. There is some minor over-coverage in most shades but not by anything significant. If you compare the gamut coverage to the U2417HJ's you can see a slight variation between the two Samsung panels being used, as reflected in the Dell spec for colour gamut.

 

Default gamma was recorded at 2.1 average, leaving it with a small 5% deviance from the target which was reasonable. Given there is no gamma control (other than switching between PC and Mac modes) in the OSD menu, it is good news that it is close to the 2.2 target as it would have been hard to correct otherwise without a calibration device. White point was measured at a nice and accurate 6568k, being only 1% out from the 6500k we'd ideally want for desktop use.

 

Luminance was recorded at a moderate 169 cd/m2 which is a little too high for prolonged general use but not overly bright. The screen was set at a default 75% brightness in the OSD menu but that is easy to change of course to reach a more comfortable setting without impacting any other aspect of the setup. The black depth was 0.147 cd/m2 at this default brightness setting, giving us an excellent (for an IPS-type panel) static contrast ratio of 1153:1. Colour accuracy was also very good out of the box with an average dE of only 2.0, maximum of 3.1. Testing the screen with colour gradients showed smooth transitions in all shades, with only very minor gradation evident in darker tones. Overall this default setup was very good and we were pleased with the results. It was very similar to the U2417HJ as well in fact. That model had a very slightly more accurate gamma (2.2, 0% deviance) but had a warmer white point than desired at 5994k (8% deviance).

 

 

We also wanted to test the screen out of the box in the 'custom color' preset mode. This looked visibly different to the standard preset, and would also allow us access to the RGB controls in the menu for calibration later on.

This preset mode showed a very similar setup to the standard mode. Gamma remained pretty accurate at 2.1 average (5% deviance), and white point was only slightly too warm at 6340k (2% out). The RGB channels were defaulted to 100 each, and so this also resulted in a slightly brighter screen (177 cd/m2), despite the same 75% brightness setting, and also a stronger contrast ratio of 1216:1. Colour accuracy remained very good with dE average of 2.1. This mode will be better for calibration as you have access to the RGB channels here, although it's unlikely we will need to change them much given the decent white point setup already. Otherwise, there's not really much difference between this Custom Color mode and the Standard mode.

 


Factory Calibration

There is also a factory calibrated sRGB preset mode on this screen. In the box there is a calibration report provided which is unique to your particular unit. This shows that the sRGB preset mode has been factory calibrated to offer a dE of <2 (the U2417HJ had dE < 4 for its calibration) and tighter grey scale tracking. If you look at the grey scale tracking graph you can tell that the screen has apparently been calibrated to 6000k, and not 6500k for some reason.

The factory calibrated sRGB mode offers a decent setup as well. The 2.2 gamma target is now more accurately met, with a 0% deviance on average and correcting the 5% deviance we'd seen in the other preset modes tested above. White point is "correct" in that it is calibrated to our preferred target of 6500k nicely, although the Dell calibration report suggests it should have been set to 6000k. We are pleased though that it has not been. On the U2417HJ it had been set to 6000k as well, which is what that model delivered. Colour accuracy is within targets just, with dE of 2.0 average, but a max ranging up to 6.0. Contrast ratio remains strong for an IPS-type panel at 1142:1. This mode is a good factory calibration actually, and offers a more accurate overall setup than the 'standard' or 'custom color' modes out of the box, mainly because the gamma curve is more accurate. It should be a decent setup for most casual users we expect.

 

 

Calibration

 

We used the X-rite i1 Pro 2 Spectrophotometer combined with the LaCie Blue Eye Pro software package to achieve these results and reports. An X-rite i1 Display Pro colorimeter was used to validate the black depth and contrast ratios due to lower end limitations of the i1 Pro device.

We changed to the 'custom color' preset mode which offered us access to the RGB controls from within the menu. We adjusted the RGB channels and brightness setting as shown in the table above. All these OSD changes allowed us to obtain an optimal hardware starting point and setup before software level changes would be made at the graphics card level. We left the  LaCie software to calibrate to "max" brightness which would just retain the luminance of whatever brightness we'd set the screen to, and would not in any way try and alter the luminance at the graphics card level, which can reduce contrast ratio. These adjustments before profiling the screen would help preserve tonal values and limit banding issues. After this we let the software carry out the LUT adjustments and create an ICC profile.

 

Average gamma was now corrected to 2.2 average with a 0% deviance, correcting the 5% deviance we'd seen out of the box in this preset mode. The white point had now been corrected to 6560k, leaving it with a minor 1% deviance now. Luminance had been improved thanks to the adjustment to the brightness control and was now being measured at 121 cd/m2. This left us a black depth of 0.10 cd/m2 and gave us an excellent static contrast ratio (for an IPS-type panel) of 1204:1. Colour accuracy of the resulting profile was excellent, with dE average of 0.3 and maximum of 0.9. LaCie would consider colour fidelity to be very good overall. Testing the screen with various colour gradients showed smooth transitions. There was some very slight gradation in darker tones and a very small amount of banding introduced due to the adjustments to the graphics card LUT from the profilation of the screen. You can use our settings and try our calibrated ICC profile if you wish, which are available in our ICC profile database. Keep in mind that results will vary from one screen to another and from one computer / graphics card to another.

 

 

 

 

Calibration Performance Comparisons


 

The comparisons made in this section try to give you a better view of how each screen performs, particularly out of the box which is what is going to matter to most consumers. When comparing the default factory settings for each monitor it is important to take into account several measurement areas - gamma, white point and colour accuracy. There's no point having a low dE colour accuracy figure if the gamma curve is way off for instance. A good factory calibration requires all 3 to be well set up. We have deliberately not included luminance in this comparison since this is normally far too high by default on every screen. However, that is very easily controlled through the brightness setting (on most screens) and should not impact the other areas being measured anyway. It is easy enough to obtain a suitable luminance for your working conditions and individual preferences, but a reliable factory setup in gamma, white point and colour accuracy is important and not as easy to change accurately without a calibration tool.

 

From these comparisons we can also compare the calibrated colour accuracy, black depth and contrast ratio. After a calibration the gamma, white point and luminance should all be at their desired targets.

 

 

Default setup of the screen out of the box was mostly very good with a fairly accurate gamma of 2.1 (5% deviance), reliable white point of 6568k (1% out), low dE of 2.0 and a high contrast ratio. The factory calibrated sRGB will correct the small gamma deviance which returns a slightly better overall setup we felt.

 

It's worth comparing the U2417H with the previous U2414H model. The U2417H is fairly similar to the old model, which also showed a 5% gamma deviance (2.3 average), minor 1% white point deviance and a slightly higher dE average (2.3). There is an improvement in contrast ratio though with the new model, which is a decent improvement for sure from 970:1 to 1204:1.

 

 

 

The display was excellent when it came to contrast ratio for an IPS-type panel. It offered a very impressive 1204:1 calibrated contrast ratio, significantly surpassing the previous U2414H model which reached 970:1. It was actually one of the highest calibrated contrast ratio we have seen from any IPS-type panel, going beyond our previous champion, the Dell U2515H at 1138:1 and falling only ever so slightly lower than the U2417HJ (1228:1). Of course it can't compete with VA panel types which can reach over 2000:1 easily, and commonly up to 3000:1, even close to 5000:1 in the case of the Eizo FG2421. These VA panels are not shown in the graph above.

 


Viewing Angles


Above: Viewing angles shown from front and side, and  from above and below. Click for larger image

Viewing angles of the screen were very good as you would expect from an IPS-type panel. Horizontally there was very little colour tone shift until wide angles past about 45. A slight darkening of the image occurred horizontally from wider angles as you can see above as the contrast shifted slighting. Contrast shifts were slightly more noticeable in the vertical field but overall they were very good. The screen offered the wide viewing angles of IPS technology and was free from the restrictive fields of view of TN Film panels, especially in the vertical plane. It was also free of the off-centre contrast shift you see from VA panels and a lot of the quite obvious gamma and colour tone shift you see from some of the modern VA panel type offerings. All as expected really from a modern IPS panel and comparable to the old U2414H.

The viewing angles were better than we'd seen from the recently tested Dell U2417HJ (with a very similar Samsung PLS panel). That model had surprised us as it had more restrictive viewing angles than we are used to from this technology, but it's good to see that those steps in the wrong direction are not carried over to the U2417H.


Above: View of an all black screen from the side. Click for larger version

On a black image there is a characteristic pale glow introduced to the image when viewed from a wide angle, commonly referred to as IPS glow. This is a bit more than we'd seen from the U2417HJ which we had labelled as a moderate-glow panel. It's also not a low-glow panel like the previous U2414H was, where that showed very little IPS glow at all.
 


Dell U2417H Now Available



Panel Uniformity

We wanted to test here how uniform the brightness was across the screen, as well as identify any leakage from the backlight in dark lighting conditions. Measurements of the luminance were taken at 35 points across the panel on a pure white background. The measurements for luminance were taken using BasICColor's calibration software package, combined with an X-rite i1 Display Pro colorimeter with a central point on the screen calibrated to 120 cd/m2. The below uniformity diagram shows the difference, as a percentage, between the measurement recorded at each point on the screen, as compared with the central reference point.

It is worth noting that panel uniformity can vary from one screen to another, and can depend on manufacturing lines, screen transport and other local factors. This is only a guide of the uniformity of the sample screen we have for review.
 


Uniformity of Luminance

The luminance uniformity of the screen was decent overall. There was a drop in luminance on the left and right hand edges of the screen where in the worst case the luminance dropped to 99 cd/m2 (-21%). That was the most extreme example though and in fact 80% of the screen was within a 10% deviance from the centrally calibrated point which was good.


Backlight Leakage


Above: All black screen in a darkened room. Click for larger version

We also tested the screen with an all black image and in a darkened room. A camera was used to capture the result. The camera showed there was no real backlight bleed or clouding at all which was great news.

Note: if you want to test your own screen for backlight bleed and uniformity problems at any point you need to ensure you have suitable testing conditions. Set the monitor to a sensible day to day brightness level, preferably as close to 120 cd/m2 as you can get it (our tests are once the screen is calibrated to this luminance). Don't just take a photo at the default brightness which is almost always far too high and not a realistic usage condition. You need to take the photo from about 1.5 - 2m back to avoid capturing viewing angle characteristics, especially on IPS-type panels where off-angle glow can come in to play easily. Photos should be taken in a darkened room at a shutter speed which captures what you see reliably and doesn't over-expose the image. A shutter speed of 1/8 second will probably be suitable for this.

 


General and Office Applications

With a 1920 x 1080 resolution, the desktop real estate  of the U2417H feels a step down compared with all the high resolution panels we've tested, and the 27" 2560 x 1440 models we are used to using day to day. You do lose a large amount of desktop space, and although side by side split screen working is possible, it's not as easy due to the more limited resolution and space. With a 0.2745mm pixel pitch, text is comfortable and easy to read natively, providing a sharp and crisp image. It is not as sharp as the 1440p panels we've become accustomed to, or of course any ultra HD/4K resolutions where scaling is used, but it is perfectly adequate. For this size screen, 1920 x 1080 is about your limit of sensible resolution without needing to use operating system scaling options.

The very thin bezel design mean that the U2417H could be easily integrated into a multi-screen set up if you wanted, and we liked the new 4-side "frameless" design. The light AG coating of the panel is welcome, and much better than the grainy and 'dirty' appearance of older IPS AG coatings. The wide viewing angles provided by this panel technology on both horizontal and vertical planes, helps minimize on-screen colour shift when viewed from different angles and thankfully they were in keeping with typical IPS panel performance, and better than the somewhat surprising viewing angles we saw from the HJ model. The default setup of the screen (particularly the factory calibrated sRGB preset) was very good as well, offering an accurate gamma curve, accurate white point, decent contrast ratio and low dE.

The brightness range of the screen was also very good, with the ability to offer a luminance between 241 and 32 cd/m2, pretty much identical to the HJ model as well. This should mean the screen is perfectly useable in a wide variety of ambient light conditions, including darkened rooms. A setting of ~47 in the OSD brightness control should return you a luminance close to 120 cd/m2 out of the box if you stick to the 'standard' preset mode. Otherwise you might want to try the settings from our calibration section. On another positive note, the brightness regulation is controlled without the need for the use of the now infamous Pulse-Width Modulation (PWM), and so those who suffer from eye fatigue or headaches associated with flickering backlights need not worry. We don't know why Dell don't start promoting this as a feature really, as it's a big pro. There was no audible noise or buzzing from the screen, even when specifically looking for it using test images with a large amount of text at once. The screen also remains cool even during prolonged use.

There are a few extras provided here as well including a 4 port USB 3.0 hub (2x easy access on the left hand side, one with charging support), and an audio output for speaker connection. We preferred the location of those 2 USB ports on the left hand side of the screen as they are much easier to get to than when they are on the back of the screen, like they were on the HJ model. There were no further extras such as ambient light sensors or card readers on this model which can be useful in office environments. The H model does not feature the wireless charging function of the HJ model either. There was a good range of ergonomic adjustments available from the stand allowing you to obtain a comfortable position for a wide variety of angles. The VESA mounting support may also be useful to some people as well.

 
Above: photo of text at 1920 x 1080 (top) and 1600 x 900 (bottom)

The screen is designed to run at its native resolution of 1920 x 1080 and at a 60Hz recommended refresh rate. However, if you want you are able to run the screen outside of this resolution. We tested the screen at a lower 1600 x 900 resolution to see how the screen handles the interpolation of the resolution, while maintaining the same aspect ratio of 16:9. At native resolution the text was sharp and clear. When running at a the lower  resolution the text is still reasonably clear, with moderate levels of blurring. You do lose a lot of screen real-estate as well of course but the image seems to be interpolated quite well from lower resolution sources.

The U2417H is rated by Dell as having a 6ms G2G response time (fast setting) or an 8ms G2G response time (normal setting). Both specs indicate the panel uses overdrive / response time compensation (RTC) technology to boost pixel transitions across grey to grey changes. On this H model (but not the HJ) there is an additional 'response time' setting available which allows you to switch from the 'normal' 8ms G2G mode, to a 'fast' 6ms G2G mode. We've found this setting on other Dell screens to not really offer anything practically useful and would expect the 'normal' mode to be optimal anyway.

The part being used is the Samsung LTM238HL04 PLS (IPS-type) panel. Have a read about response time in our specs section if you need additional information about this measurement.

We will first test the screen using our thorough response time testing method. This uses an oscilloscope and photosensor to measure the pixel response times across a series of different transitions, in the full range from 0 (black) to 255 (white). This will give us a realistic view of how the monitor performs in real life, as opposed to being reliant only on a manufacturers spec. We can work out the response times for changing between many different shades, calculate the maximum, minimum and average grey to grey (G2G) response times, and provide an evaluation of any overshoot present on the monitor.

We use an ETC M526 oscilloscope for these measurements along with a custom photosensor device. Have a read of our response time measurement article for a full explanation of the testing methodology and reported data.
 


'Response Time' Setting (Overdrive)

The 'response time' setting is available via the display section of the OSD menu as shown above. We will test both modes to see which is optimal first of all.


In the 'normal' response time mode the average G2G response time was measured at 8.7ms which is fairly typical for a 60Hz IPS panel. Some fairly moderate overshoot was starting to creep in though on some transitions, particularly when changing from black > grey. In practice this was not overly obvious though. As you moved up to the 'fast' mode, the response times were reduced down to 6.9ms G2G average, but at the cost of some high amounts of overshoot. This was noticeable and distracting in actual use as well, so this mode should probably be avoided. Stick with the 'normal' setting for optimal performance, the 'fast' mode was just too aggressive.

 


Detailed Response Time Measurements

We stuck with the optimal 'normal' response time setting. The average G2G response time was measured at 9.1ms which was good overall for a 60Hz IPS-type panel. Rise times (changes from dark to light shades) were slightly slower than fall times (changes from light to dark shades) but not by anything significant. Some measurements reached below the 8ms advertised figure as well.

 

If we evaluate the Response Time Compensation (RTC) overshoot then the results are pretty good and there is only low to moderate overshoot to be seen. A couple of the measured transitions showed a fairly high overshoot, like those from black to grey (0 > x). But there were only a few transitions which showed anything particularly noticeable. We know that the 'fast' overdrive setting is too aggressive and leads to a lot more overshoot.

 


Display Comparisons

The above comparison table and graph shows you the lowest, average and highest G2G response time measurement for each screen we have tested with our oscilloscope system. There is also a colour coded mark next to each screen in the table to indicate the RTC overshoot error, as the response time figure alone doesn't tell the whole story.

The response time performance of the U2417H were slightly slower than the best 60Hz IPS-type panels we've tested. The best models we've tested reach down to around 8.6ms G2G with no overshoot problems. Here, the response times were a tad slower at 9.1ms, and there was some moderate levels of overshoot starting to creep in. It was slightly worse than the HJ version of this screen as well, which has a slightly different Samsung panel, and also the old U2414H. To be honest you would be extremely unlikely to spot any real difference in practice between the two. High refresh rate IPS-type panels like the Asus ROG Swift PG279Q and Acer XB270HU can reach lower response times of around 5ms G2G thanks to the boosted refresh rate. For a 60Hz IPS-type panel, the results here from the U2417H are pretty decent. Slightly behind some other competing models in this size, but not by much.

 

The screen was also tested using the chase test in PixPerAn for the following display comparisons. As a reminder, a series of pictures are taken on the highest shutter speed and compared, with the best case example shown on the left, and worst case example on the right. This should only be used as a rough guide to comparative responsiveness but is handy for a comparison between different screens and technologies as well as a means to compare those screens we tested before the introduction of our oscilloscope method.


23.8" 8ms G2G Samsung PLS (IPS-type) @ 60Hz (Response Time = Normal)

In practice the Dell U2417H showed low levels of blurring on moving images and no noticeable overshoot in these specific test. It was quite comparable to other decent 60Hz IPS-type panels we have tested in the past in these tests. There was a little more blur than the best case 60Hz IPS panels, and some overshoot starts to creep in on certain transitions we know from our oscilloscope tests. It didn't have the motion clarity of high refresh rate panels, which offer improvements thanks to reduced response times and the increased frame rate.

25" 8ms G2G LG.Display AH-IPS (Response Time = Normal)

If we compare the U2417H with a range of other recent UltraSharp screens you will see that the motion performance is very similar between all 5 models. There's very little to separate them all in practice, although the U2417H, U2515H and U2715H are perhaps ever so slightly slower than the other two with a little more pronounced blur.



Additional Gaming Features

Aspect Ratio Control - Like the U2417HJ, U2414H, U2515H and U2715H models, the new U2417H has 3 options for aspect ratio control through the OSD 'Display' menu as shown above. There are options for wide 16:9, 5:4 and 4:3 only. There is no 1:1 pixel mapping mode specifically but given a lot of content from external devices is 16:9 aspect ratio by default, the native aspect of the screen can at least accommodate that nicely. You will have to put up with the screen interpolating content up to the full size of the screen when using an external device, as you can't use any kind of 1:1 scaling option on this model.

Preset Modes - There is a specific 'game' available in the OSD which appears to make the image a tad warmer than our calibrated custom mode. It gives you access to the dynamic contrast ratio control if you want to use it as well.



Lag

We have written an in depth article about input lag and the various measurement techniques which are used to evaluate this aspect of a display. It's important to first of all understand the different methods available and also what this lag means to you as an end-user.

Input Lag vs. Display Lag vs. Signal Processing

To avoid confusion with different terminology we will refer to this section of our reviews as just "lag" from now on, as there are a few different aspects to consider, and different interpretations of the term "input lag". We will consider the following points here as much as possible. The overall "display lag" is the first, that being the delay between the image being shown on the TFT display and that being shown on a CRT. This is what many people will know as input lag and originally was the measure made to explain why the image is a little behind when using a CRT. The older stopwatch based methods were the common way to measure this in the past, but through advanced studies have been shown to be quite inaccurate. As a result, more advanced tools like SMTT provide a method to measure that delay between a TFT and CRT while removing the inaccuracies of older stopwatch methods.

In reality that lag / delay is caused by a combination of two things - the signal processing delay caused by the TFT electronics / scaler, and the response time of the pixels themselves. Most "input lag" measurements over the years have always been based on the overall display lag (signal processing + response time) and indeed the SMTT tool is based on this visual difference between a CRT and TFT and so measures the overall display lag. In practice the signal processing is the element which gives the feel of lag to the user, and the response time of course can impact blurring, and overall image quality in moving scenes. As people become more aware of lag as a possible issue, we are of course keen to try and understand the split between the two as much as possible to give a complete picture.

The signal processing element within that is quite hard to identify without extremely high end equipment and very complicated methods. In fact the studies by Thomas Thiemann which really kicked this whole thing off were based on equipment worth >100,1000 Euro, requiring extremely high bandwidths and very complicated methods to trigger the correct behaviour and accurately measure the signal processing on its own. Other techniques which are being used since are not conducted by Thomas (he is a freelance writer) or based on this equipment or technique, and may also be subject to other errors or inaccuracies based on our conversations with him since. It's very hard as a result to produce a technique which will measure just the signal processing on its own unfortunately. Many measurement techniques are also not explained and so it is important to try and get a picture from various sources if possible to make an informed judgement about a display overall.

For our tests we will continue to use the SMTT tool to measure the overall "display lag". From there we can use our oscilloscope system to measure the response time across a wide range of grey to grey (G2G) transitions as recorded in our response time tests. Since SMTT will not include the full response time within its measurements, after speaking with Thomas further about the situation we will subtract half of the average G2G response time from the total display lag. This should allow us to give a good estimation of how much of the overall lag is attributable to the signal processing element on its own.

 

Lag Classification


To help in this section we will also introduce a broader classification system for these results to help categorise each screen as one of the following levels:

  • Class 1) Less than 16ms / 1 frame lag - should be fine for gamers, even at high levels

  • Class 2) A lag of 16 - 32ms / One to two frames - moderate lag but should be fine for many gamers. Caution advised for serious gaming and FPS

  • Class 3) A lag of more than 32ms / more than 2 frames - Some noticeable lag in daily usage, not suitable for high end gaming

We have provided a comparison above against other models we have tested to give an indication between screens. The screens tested are split into two measurements which are based on our overall display lag tests (using SMTT) and half the average G2G response time, as measured by the oscilloscope. The response time is split from the overall display lag and shown on the graph as the green bar. From there, the signal processing (red bar) can be provided as a good estimation.

Correction 16/8/16: We've had a few emails about the lag on the U2417H since we published this review, and comparisons with the measurement made at PCmag where they had used the Leo Bodnar device to measure a 10.2ms total lag. We can't really comment on the accuracy or otherwise of that device, but something didn't seem right. We will hold our hands up here as it looks like we've made a mistake with the lag measurements of this screen. The important thing is correcting that now, as we're sure it has an influence on people looking at buying this screen. Thanks to our friends at Pcmonitors.info who are currently testing the HA model with the same SMTT 2.0 tool we use we've managed to figure out what has happened here and corrected our measurement results above. It seems that (very unusually) the U2417H shows an increased lag when non-native resolutions are used on the screen. The scaling options in the OSD don't seem to impact it though. Our original measurements showed a total lag of 26.36ms, with an estimated signal processing lag therefore as 21.81ms in those circumstances. However, when running the screen at native res, the total lag was ~5ms which is much better, giving a signal processing lag of only 0.45ms (basically nothing). We apologise for the confusion with the results previously published. To be honest, we've not seen the lag vary like that before so it's an oddity which we will account for in the future as well.



Movies and Video

The following summarises the screens performance in video applications:

  • 23.8" screen size makes it a reasonable option for an all-in-one multimedia screen, but being quite a bit smaller than most modern LCD TV's of course.

  • 16:9 aspect ratio is more well suited to videos than a 16:10 format screen, leaving smaller borders on DVD's and wide screen content at the top and bottom.

  • 1920 x 1080 resolution can support full 1080 HD resolution content

  • Digital interfaces support HDCP for any encrypted and protected content

  • Good range of connectivity options provided with DisplayPort, Mini DisplayPort and HDMI (with MHL) offered.

  • Cables provided in the box for DisplayPort to Mini DP only.

  • Light AG coating a positive change providing clean and clear images, without the unwanted reflections of a glossy solution.

  • Wide brightness range adjustment possible from the display, including a maximum luminance of ~241 cd/m2 and a decent minimum luminance of 32 cd/m2. This should afford you good control for different lighting conditions. Contrast ratio remains stable across that adjustment range as well and is excellent for an IPS-type panel. Brightness regulation is controlled without the need for PWM and so is flicker free for all brightness settings.

  • Black depth and contrast ratio are very strong for an IPS-type panel at 1204:1 after calibration. Detail in darker scenes should not be lost as a result.

  • There is a specific 'movie' preset mode available for movies or video if you want but it is much cooler than our calibrated custom mode. May be useful to some though.

  • Good pixel responsiveness which should still be able to handle fast moving scenes in movies without issue. Low overshoot issues which is pleasing.

  • Wide viewing angles thanks to IPS-type panel technology meaning several people could view the screen at once comfortable and from a whole host of different angles. Thankfully better than the HJ model which were for some reason more limited than usual IPS-type panels.

  • IPS glow is moderate meaning you might experience some annoying white glows on darker content from an angle. It is not a low-glow panel like the U2414H before it.

  • Very good and mostly easy to use range of ergonomic adjustments available from the stand, so should be easy to obtain a comfortable position for multiple users or if you want to sit further away from the screen for movie viewing.

  • No noticeable backlight leakage, and none from the edges which is good. This type of leakage may prove an issue when watching movies where black borders are present but it is not a problem here.

  • No integrated stereo speakers on this model but it is compatible with Dell's SoundBar if you want. There is also an audio output connection.

  • Moderate range of hardware aspect ratio options with 16:9, 5:4 and 4:3 modes available which should be fine for most uses.

  • Picture in picture (PiP) and Picture By Picture (PbP) are not available.
     


Conclusion

It was interesting to test the U2417H having only recently tested the HJ version. To be honest we weren't expecting much difference given the use of a Samsung PLS panel in both, and given they are equivalent replacements to the successful U2414H of a few years ago. The obvious differences first of all are the design, connections, USB port location and presence/absence of a wireless charging function in the stand. We liked that wireless charging feature on the HJ, although appreciate not everyone will want or need it. We did prefer the new sleek infinity edge design of the H model though and the darker silver stand and base. Having the arm-mounting option for the HA version is also useful for some.

Underneath all that, despite both new models using a Samsung PLS panel, there are some differences in performance to be aware of. Of most significant difference are the viewing angles. The HJ had disappointed us with its rather restrictive viewing angles, something we're not accustomed to seeing from an IPS-type panel at all. Thankfully the H was better and more what you would hope for from this tech. As a small trade off, the HJ seemed to have a little less IPS-glow on dark content, although neither model were as low-glow as the U2414H before them.

There were some more minor differences in other areas as well as some similarities. Default setup was pretty comparable between the H and HJ to be fair, as was brightness adjustment range and contrast ratio. Both were PWM-free and had light AG coating which was pleasing. Response times did vary a little, with the H being a tad slower and having a little more overshoot than the HJ. The additional 'fast' response time setting was pretty pointless as well. The lag was basically the same and non-existent on both which is good news.

We still felt that the U2417H was a very strong all round performer and at its competitive price it's a decent 24" sized option for a whole range of uses. If you're aware of the differences in features and performance you can pick between the H and HJ (or maybe HA) to meet whatever needs you have nicely.

If you appreciate the review and enjoy reading and like our work, we would welcome a donation to the site to help us continue to make quality and detailed reviews for you.
 

Pros

Cons

Good factory calibration, strong contrast ratio and great all-round performance

 Response times not quite as good, although not bad still

Viewing angles are wide and as you'd hope for from an IPS-type panel, and thankfully better than the U2417HJ

Moved away from a low glow panel of the U2414H before it and a bit more glow than the HJ

Nice new Infinity Edge design and 4 side zero bezel design

Not much really new compared with the old U2414H


Dell U2417H Now Available


 

TFT Central Awards Explained

We have two award classifications as part of our reviews. There's the top 'Recommended' award, where a monitor is excellent and highly recommended by us. There is also an 'Approved' award for a very good screen which may not be perfect, but is still a very good display. These awards won't be given out every time, but look out for the logo at the bottom of the conclusion.
