Hazro to Launch New Range of 23 - 24" IPS Screens
July 28th 2010

In some exclusive news, we have been given some advanced details of some interesting new models from Hazro. First, a bit of a history lesson - It was back in November 2007 that we brought you the details of this new monitor manufacturer, offering some interesting new models in 23, 24, 26 and 30” sizes. All the new models offered an attractive aluminium design and high end IPS panel technology. In Dec 07 we featured the first review of the 24” HZ24W, followed by the 26” HZ26W in Feb 08 and the 30” HZ30W in July 08. You can read the reviews for all the information and opinions, but the range attracted a lot of interest across the web.

In July 2008 Hazro announced some updates to their range, addressing some minor issues and adding some features like HDMI, HDCP and even a glossy panel coating on the 24” model. Later that year we took a look at the updated 26” HZ26Wi.

We have received some information about new models in their range which look very interesting indeed. Please note that these are provisional model numbers and may change before release:

  • HZ23We – a 23” model based on the same e-IPS panel as used in the popular NEC EA231WMi, Dell U2311H and Viewsonic VP2365wb. We have already featured reviews of all three of these models, so it will be very interesting to see where the new Hazro offering fits in. One of the key selling points of this particular model is that it will be factory calibrated to the sRGB standard at a hardware level using the 12-bit internal LUT. Each RGB value form 0~255 has been calibrated to achieve a perfect 2.2 gamma curve. Note that this is not accessible by the user however. This puts the Hazro offering in an interesting position competing more at the higher end than the mainstream offerings from the other manufacturers. The screen is standard gamut as well and is supplied with a hood.

Another interesting feature of this model, and something which will please those who have had difficulties with the NEC/Dell/Viewsonic models, is that the panels have been selected to offer optimum uniformity, and will be dispatched with a full panel uniformity report. This should hopefully overcome some of the luminance, colour and backlight uniformity problems we saw from the other three models, and which have caused a lot of grief to some users.

We will feature a full review of the screen when it is completed, and will also be testing a trial unit over the next couple of weeks. If there are features you would like to see included, or questions you might have, please post in our forum and I will pass them on to Hazro.
 

  • HZ24Wa – a 24” model using the same H-IPS panel as the HP ZR24W. There aren’t many 24” models out there with a standard sRGB (72% NTSC) gamut so this will be a welcome addition I’m sure. This model should feature a good range of interface options as well including HDMI, DVI, VGA, component and Audio.


The following two 24” models are also already listed on Hazro’s website, although won’t be available straight away. We will arrange for a full review as and when they become available so you will see these new models first at TFT Central.

  • HZ24WLED (aka HZ24Wd)Launched as a mid-application monitor aimed at the more discerning buyer, the HZ24WLED has been specifically optimised for use in environments where high colour saturation, brightness and gamut are critical. The screen features an LED Backlight H-IPS panel along with DVI, HDMI, component and D-sub interfaces. The new LED backlit 24” will use the  same IPS panel as used in the high end Apple Cinema Display and will feature a glossy panel coating. There is a wide range of interface options available as well.

 

  • HZ24WBR1 (aka HZ24Wc) - The Hazro HZ24WBR1 is a professional grade LED backlight monitor aimed primarily at the broadcast, graphic design, photography and video editing markets. Featuring a true 10bit H-IPS panel, the HZ24WBR1 is capable of producing over 1.073 Billion colours which offers far superior colour reproduction, white uniformity and rendering than 8bit panels. The monitor is a wide gamut display [130% NTSC] allowing users to work in a multitude of colour workspaces including sRGB, Adobe RGB, REC 709, SMPTE C, EBU or native Wide Gamut Mode [all accessible via the OSD]. There will also be factory calibration to many colour spaces and a wide range of interface options available. This model will use the same IPS panel as the Dell U2410 and NEC PA241W, offering another solution for professional users.

 


Apple Launch 27" Cinema Display
July 28th 2010

Following in the footsteps of its 24” little brother, Apple have today announced the release of a 27” Cinema Display in their range of monitors. The IPS based screen features a 2560 x 1440 resolution, built-in iSight camera, a three port powered USB hub, and a universal MagSafe connector for charging up your MacBook. Like the 24-inch before it, Apple has really built this display to be the ultimate MacBook or MacBook Pro companion, since a single cable breaks out into the USB, Mini DisplayPort (with audio support), and MagSafe plug that are just about all your laptop requires when sitting down at a desk.

The screen looks to be using a slightly different panel to LG.Display’s LM270WQ1, that being used by Dell in their U2711. The Apple model will however feature an LED backlit module. Apple list the screen as supporting 16.7m colours as opposed to 1.07b as advertised by Dell, an indication that this particular module is 8-bit as opposed to 10-bit (or 8-bit +AFRC rather). Apple also list a 375 cd/m2 brightness, relating to the use of LED backlighting and offers a 12ms response time (no mention of whether that is G2G or ISO). There is a listed 1000:1 contrast ratio and 178/178 viewing angles.

The screen is expected to retail for $999 USD which is actually slightly less than Dell’s competing U2711. It is expected to be available around September

Acer S1 Series with LED Backlighting - The Slimmest in the World
July 28th 2010

At only 13mm thickness in the best example, the new S1 series from Acer is being promoted as the thinnest monitor range in the World. The screens are available in four sizes - 18.5, 20, 21 and 23" the new models stand out for their eye-catching design and ultra-slim profile, ranging from only 13mm for the S191HQL and the S221HQL to less than 15mm for the S231HL model.  Acer's press release states: "With clean lines, a polished black bezel and graceful glossy foot stand, the S1 series is the perfect blend of ultra slim, sophistication and style."

In line with Acer constant efforts to design products with lower environmental impact, all S1 models are integrating LED backlight technology, a technology that does not contain hazardous substances such as mercury or halogen gases and compared to a traditional lamp can reduce power consumption up to 68%. This translates to big savings, while preserving nature’s energy resources.

The new S1 series will feature Acer's eColor Management technology, a series of preset modes for operation in different conditions and work-flows. It also offers Adaptive Contrast Management (ACM) offering dynamic contrast ratios of up to 12 million:1 apparently. There is also Acer's eDisplay Management, a powerful tool enabling advanced colour calibration and display management. Each personalized setting can be stored and quickly recalled for different applications and light conditions. The models are all TN Film based.

The Acer S1 series are available now with SRRP’s (inc VAT) from: S191HQL - £119.99, S201HL – £129.99, S221HQL - £159.99 and S231HL - £169.99 

 


AOC Release Ten New Screens from 18.5 to 23"
July 28th 2010

AOC have today released details of 10 new models aimed at business and home users alike, ranging in size from 18.5" to 23", LED backlighting technology is features in four of these helping to keep a thin monitor profile and conserve energy. There's the usual blurb about good contrast ratios and response time, but no more specific detail at this time. I expect all models will be TN Film based in keeping with the rest of AOC's range.

The two 21.5" sized models (2241Sg and 2241Vg) also feature an option glass panel coating for protection, and for those who like the glossy appearance.

The ten new displays will be available in August. Retail prices have yet to be determined.

 


Acer S273HL WLED Based 27" Display Released
July 13th 2010

Building on the success of its ultra-slim and award winning Full HD LED display series, Acer expands the S3 series with the new S273HL. This new screen is 27" in size and offers an impressive spec including a 2ms G2G response time and reported 12 million to 1 dynamic contrast ratio. The screen is very thin in design at only 21mm thickness, creating a professional and minimalist look. Adding form to the elegantly simple design is a cylinder hinge on the rear and an L-shaped base with brushed-metal finish, accented by an LED light that glows in soft blue when the power is turned on. Thanks to its distinctive shape the base can easily accommodate the keyboard, saving precious space, plus it skillfully integrates a speaker for added functionality.

The S273HL integrates White LED technology that does away with hazardous substances such as mercury or halogen gases. Plus, compared to the traditional CFFL displays the S273HL can reduce power consumption by up to 63%. This translates to big cost savings, while preserving nature’s energy resources. The panel offers 70% coverage of the NTSC colour gamut and there are integrated speakers as well.

Dell Sneak Out 'Professional' P2311H 23" Monitor
July 13th 2010

Dell's website has recently seen the addition of a new 23" model, that being the 'Professional' P2311H. This came out without much fuss and coverage but Dell's blurb states: "Combining energy-conscious, environmentally sound design with reliable office performance and user comfort, the Dell Professional P2311H 23"W monitor can help manage costs while raising productivity across your entire organization."

The new screen uses LED backlighting to offer low power consumption along with environmentally sound materials. During operation the screen is reported to use only 27W of power and less than 1W in sleep mode. The 'professional' tag is not however a reflection of the panel technology used here, but a name which places it in the 'office' category of screens for business use. It's a panel designed for those who are concious of their carbon footprint and want a lower cost but high end panel for office work and multiple desktops.

ViewSonic VX2250wm-LED with WLED Backlight
May 21st 2010

Following a current trend, Viewsonic have recently released details of their new 21.5" sized screen, featuring WLED backlighting technology. This is designed with energy saving in mind, apparently saving ~40% compared with a regular 22" monitor. Apart from that, the screen offers a 1080 HD resolution, massive (although dubious) 10 million :1 dynamic contrast ratio and integrated stereo speakers.

AOC e2239Fwt Multitouch 21.5" Display
May 21st 2010

AOC have recently announced a new 21.5" display in their range aimed at notebook users in particular. The design of the screen allows the notebook to be placed between the screens two feet, saving valuable desktop space. AOC's press release states:

"Connecting an external display with a mobile computer is easily done. However, most monitor stands are located at the centre of the bezel, which means that an opened notebook can only be positioned at an angle. The resulting slanted visual angle is everything but ergonomic for longer periods of use and quickly leads to fatigue as well as neck strain. AOC banks on an entirely different concept: because of the two feet found on either side of the monitor, the notebook can be neatly placed underneath the display.

The easily operated multitouch screen function (supported by Microsoft Windows 7 Multitouch) opens up multiple ways of interacting with the computer: working more efficiently, browsing through photo albums, surfing on the Internet, playing games, enjoying music collections or action-packed blockbusters – it’s all possible through a light tap or move of the finger(s) on the screen. All adjustments to the display parameters can be carried out via the touch-sensitive touch buttons tastefully integrated into the bezel."

The screen uses WLED backlighting technology for thin screen profile. The screen is reported to offer a massive 20 million : 1 dynamic contrast ratio, but we all know how unreliable these specs can be in real terms. There are 3x USB 2.0 ports and stereo speakers built into the screen. The e2239Fwt will also consume less than 25 watts when in use and <1W when in standby.

The e2239Fwt will be available from June; the retail price has not been set so far.

Some early UK pricing lists the U2211H at around £255 GBP (inc delivery) while the U2311H is about £273. These models do not appear on Dell's official website in the UK yet. Release is expected very soon and we hope to feature a review of both these models when they become available.

 


Dell Release new 21.5" U2211H and 23" U2311H IPS Monitors
May 12th 2010

Details of two new IPS based models have emerged recently on Dell's website, at least for now in Asian regions. There are new 21.5" and 23" models, named the U2211H and U2311H. Both models offer a full 1080 HD resolution and come with a decent range of ergonomic adjustments and interfaces. Both have tilt, height, pivot and rotate functions and they have DVI (with HDCP), VGA and DisplayPort interfaces.

Both models are IPS based and offer a standard gamut of 72% NTSC coverage (~100% of the sRGB reference space). There are also 4 integrated USB ports on each model. Further specs are available below.

NEC PA271W Shipping Soon and SpectraView II Update
May 10th 2010

We reported some early details of the new PA series of screens from NEC back in February, and late followed it up with a full review of the 24" PA241W model. NEC have just announced the imminent release of the 27" model in the range, the PA271W. "Boasting a 10-bit p-IPS panel, a 2560 x 1440 pixel resolution and internal 14-bit programmable 3D lookup tables (LUTs), the MultiSync PA271W can display 1.07 billion colors out of a palette of 4.3 trillion when using the 10-bit DisplayPort input"

The screen will offer a whole host of advanced features for colour enthusiasts and the professional market which are very similar to those featured in the PA241W, just with a larger screen size.

Full NEC Specs
 

The new MultiProfiler application is exclusive to the MultiSync PA Series and provides easy-to-use control over several features. The application features Picture Mode preset configuration, which utilizes the SpectraViewII Engine in all MultiSync PA Series displays to allow multiple color modes to be quickly configured based on gamma characteristics, color gamut, white point and brightness for applications such as real-time print preview and matching of legacy displays. The Picture-in-Picture (PIP) configuration allows two video signals to be viewed simultaneously in a secondary PIP or Picture-by-Picture (PBP) window configuration. MultiProfiler also allows users to manage the monitor's USB hub and map the various monitor inputs, such as multiple computers attached to one display. The automatic generation of ICC profiles by MultiProfiler aids users when switching between or adjusting color modes. MultiProfiler is compatible with Apple Mac OS 10.3.9 or higher and Microsoft Windows 2000, XP, Vista and Windows 7.

 

The new release of SpectraViewII version 1.1.04 brings the complete color calibration solution for NEC displays to the MultiSync PA Series. In addition, the arrival of two new SpectraViewII models, the 24-inch PA241W-BK-SV and 27-inch PA271W-BK-SV, offer highly accurate color for demanding users who wish to carry out hardware level calibration and correction. At the time we tested the PA241W, the SpectraView II software was not up to date enough to support the screen, and the model was also not the specific SpectraView version.

 

According to NEC, the MultiSync PA271W is available for May 2010 shipment with an estimated street price of $1,399. We have been told that UK stock should start to become available mid June at the moment. I've also been told that the 23" model is currently expected in October, but the 30" model not until January 2011.

The MultiSync PA241W-BK-SV and PA271W-BK-SV models with SpectraViewII are available for May 2010 shipment with an estimated street price of $1,329 and $1,649, respectively. MultiProfiler is complimentary to all MultiSync PA Series customers at www.necdisplay.com/multiprofiler. The SpectraViewII upgrade is free to download for all current SpectraView customers or for purchase for new customers at www.necdisplay.com/spectraview.

ViewSonic VX2739wm - The World's First 1ms Monitor!
May 7th 2010

It's been quite a long time since we saw 2ms rated screens emerge in the market back in 2005, and now Viewsonic have just released the World's first 1ms TFT monitor! The new 27" sized screen in their VX series was actually shown at this years CES where it was reported to have a 2ms response time. Viewsonic have obviously decided to push it even more to find a niche in the market. The screen offers a pretty decent range of specs all round, including a reported 1200:1 static contrast ratio and even a 100,000:1 dynamic contrast ratio. The panel is TN Film based as you might expect given this is a gamers orientated screen, and so those contrast ratio claims may be somewhat exagerated. Will be interesting to see how this new one performs.

The information on Viewsonic's webpage is a little confusing as it talks about response time being the ISO black > white > black change first of all, being limited to 5ms (which is true for TN Film panels). It then goes on to say manufacturers improved response time to 2ms, but doesn't mention that this is a grey to grey (G2G) measurement thanks to the implementation of Response Time Compensation (RTC) technologies, and the ISO response time remains unchanged really. It doesn't then stipulate what the 1ms represents, but it must surely be the G2G response time they are talking about here, with an even stronger RTC impulse than normal. I note that the OSD offers a 'response time' control of some sort according to the specs, presumably to control the level of RTC impulse or turn it off altogether. Let's hope that the aggressive RTC needed to give a 1ms response time doesn't come at the cost of artefacts and trailing.

The screen offers a full 1080 resolution of 1920 x 1080, with a 16:9 widescreen aspect ratio. For multimedia use, the screen offers HDCP supported digital DVI and HDMI interfaces along with integrated 'SRS Premium Sound' speakers.

HP ZR24W Review Update - Correcting Blacks and Contrast Ratio!
April 28th 2010

Like many readers, I was left a little disappointed with the HP ZR24W review in regards to the poor rendering of blacks and poor static contrast ratio. I'll give a brief summary of the issues found during the review:

  • Contrast stability tests - screen and graphics card settings are left at default with no calibration of either. The only control changed is the OSD brightness control. From the range of 0% to 100% brightness, the contrast ratio remained static at around 450:1. Since contrast ratio is directly linked to black depth vs. luminance, there's no need for me to go into black depth detail here.

  • Default Screen Testing - At default, the brightness control was set at 90%, and contrast at 80%. Testing the screen out of the box resulted in a good preset gamma of 2.2, accurate colour temperature within 3% of target (6668k) and pretty decent colour accuracy (average dE of 2.5). However, luminance was too high at 222 cd/m2, and black depth and contrast ratio were poor at 0.49 cd/m2 and 453:1 respectively.

  • Calibration - During calibration the software guided us to a new brightness control of 25%. Contrast of 80% was identified as "optimum" and so was not changed. The calibration results improved colour accuracy significantly. Luminance was now corrected nicely to 119 cd/m2 but black depth remained pretty poor at only 0.28 cd/m2, and gave a contrast ratio of 425:1. We concluded that black depth was an obvious weak point of this screen. You could achieve up to 920:1 using the dynamic contrast ratio control.

However, I still felt there was a flaw in this. Perhaps in the way the screen was set up, the calibration process or an error on my behalf. I spent many hours experimenting with different settings, calibrations and software packages to see if this could be improved. Here are my steps:


1)
Reset the screen and graphics card to factory defaults as a starting point. Taken from the full review, here is a reminder of the settings and results recorded:

2)
Since black depth was poor (0.49) and contrast ratio poor (453:1) as a result, I wanted to try and improve on this and in order to do so, I had to change something. I spent a lot of time fiddling with different settings, calibrations and software packages to see how I could improve this. Experimenting with the contrast setting seemed to have an impact.

As is normal for most displays, the contrast setting was a digital white level control. This was smooth and fairly subtle across the range from 0 - 90%. Above this, one increment steps showed significant changes. After many trials, the setting of 100% returned the highest default contrast ratio. If you lowered the contrast control below the default of 80%, it had a negative effect on the contrast ratio. I changed this setting to 100%, restored everything else to default and ran the test and report again:

 

Adjusted Settings

luminance (cd/m2)

341

Black Point (cd/m2)

0.46

Contrast Ratio

740:1

With contrast now set at 100%, luminance shot up from 222 to 341 cd/m2, but black depth actually improved slightly from 0.49 to 0.46 cd/m2. This finally gave us a good contrast ratio of 740:1. The screen was however uncomfortably bright and looked fairly washed out. Remember, the OSD brightness was still at 90% and we were in the preset 6500k mode. Colour accuracy remained similar to default settings (average dE now 3.1 instead of 2.5), but the gamma was negatively altered from our target of 2.2 to 2.0. These settings were not ideal but at least the contrast ratio has improved from our starting point. Detail was lost in darker images and in shadow detail due to the change in gamma and because the digital white point was set too high. Although this change in OSD contrast helped us improve the black depth and contrast ratio, it was not worth it in my opinion at the cost of dark detail.

It's pretty rare for a screens default contrast setting to not be optimum, and in this instance it looks like a setting of 80% has been selected to avoid colour washout and a wrongly adjusted gamma. However, it does return poor black depths and contrast ratio. We will see if we can get both!


3)
For those who don't have access to a colorimeter or calibration devices, I wanted to see whether using basic OSD adjustments could help bring the screen closer to our targets or whether altering the contrast control to 100 just made things too bright and unusable and lead to unfortunate loss of detail in darker content. Changing the brightness control will affect luminance since it is a control of the backlight intensity so this was one way to adjust the luminance of the screen.

Reducing it from 90 to 10% returned a luminance of 158 cd/m2, but lowering all the way to 0% returned 133 cd/m2. This was pretty close to our target of 120 cd/m2 and at least more comfortable to use. At this luminance, black depth was a decent 0.18 cd/m2, giving a static contrast ratio of 739:1

 

Adjusted Settings 2

luminance (cd/m2)

133

Black Point (cd/m2)

0.18

Contrast Ratio

739:1

So even average users without calibration can achieve fairly good results from this screen in regards to black depth and contrast ratio. Colour accuracy isn't quite as good as at default (average dE now 3.1 instead of 2.5). The problem with making this change is that it negatively effects the gamma, dropping you from 2.2 at default settings (80% contrast control) to 2.0. The screen was also still fairly washed out though. You can improve the contrast ratio using this method, but at the cost of detail in darker images / shadow detail which is not a good thing. I will test to see if you can get around this issue with proper calibration. It's also worth noting here that even with brightness now set at 0%, you cannot acheive the desired luminance of 120 cd/m2, so you'd also need calibration to correct that. If you don't have access to a colorimeter, you may be better sticking with an 80% contrast setting, but you will have to put up with the relatively poor black depth and contrast ratio. Might not be an issue to many people anyway, but something to keep in mind.
 


4) I carried out a calibration and profiling of the screen in the normal way but this time ignored the software's recommendation that 80% contrast was optimum. I stuck at 100% contrast control and entered the custom color mode allowing access to the RGB control. When you enter this mode, the RGB sliders are set at a maximum 255 each, and at 100% contrast, the screen was immediately impossible to use, being very bright and very washed out. Detail was being lost all over the place.

The RGB controls also have an impact on digital white point as the contrast control does, so you'd need to reduce either the contrast, or the RGB channels at an individual level. I used the software's guidance to alter the RGB controls here. Remember, when you are using one of the other presets like the default 6500k / sRGB mode, they basically just has pre-tuned RGB channels so have already done the adjustments for you. For maximum control, I wanted to use the custom color mode. As I changed these within the software, white point was being adjusted. Further adjustments would be made at a graphics card LUT level.

Validating the profile revealed that gamma was corrected back to the target of 2.2. Colour temperature was improved slightly, bringing it from its 2 - 3% deviation to <0.5% difference (6513k). With an OSD brightness now set at 7%, luminance was corrected to 120  cd/m2. This gave us a decent reduced black depth of 0.18 cd/m2, and a good static contrast ratio of 667:1. Having run this same process using the screens default 80% contrast setting, I know that although most of the results were similar, the black depth and contrast ratio suffered significantly, giving only 0.28 cd/m2 and 425:1 respectively. If you want good black depth and contrast ratio, you will need to use a contrast setting of 100% in the OSD menu. However, you will need to calibrate the screen to overcome the gamma and wash-out issues associated with that change. Colour accuracy was also corrected nicely with very impressive results obtained. Average dE was now 0.2, with a maximum of only 0.7. LaCie would consider colour fidelity to be excellent.

 

So after all these tests, we've managed to arrive at a much improved black depth and contrast ratio. I'd like to apologise to the readers now if this correction has anything to do with an error on my part. I'd rather be open and make the correction now than pretend it didn't happen. It's rare for a screens contrast setting to not be optimum at default, and the calibration software had also not managed to spot a more 'optimum' setting initially. I have updated the review to reflect these new measurements, including my conclusions and overall feelings. You can see which sections include an update if you have already read the review by referring to the 'quick browse' list at the top. Many parts of it have been updated as a result of these findings, but take note about the side-effects of making such changes to the contrast control without proper calibration.

I hope this helps potential buyers with their decision and apologies again for any confusion.

Samsung BX2440X - 24" with LED Backlight
April 16th 2010

According to Samsung's website: "Samsung’s eco-friendly LED monitors will revolutionize your business computing environment. Being halogen and lead-free, and engineered to consume 40 % less power, the BX2440X Samsung monitor is more eco-friendly than conventional CCFL monitors. The BX2440X has met strict energy and environmental requirements to become Energy Star qualified, TCO 5.0 certified and has been rated Gold by EPEAT."

The new 24" model is designed with this in mind, but offers a fairly stylish design and a nice range of  specs as well. There is an ultra-thin bezel around the screen and the monitor is a glossy black finish. The spec is modern top end TN Film, but there is a reported 5 million:1 dynamic contrast ratio, or as Samsung put it - "Mega DCR". Whether that is realistic in practice is another matter of course.

In terms of specs the BX2440X offers:

Eizo CG245W - Graphic Industry's First Self-calibrating Monitor
April 16th 2010

EIZO have recently introduced the ColorEdge CG245W, the first monitor in the graphics industry with a built-in calibration sensor and self-calibrating capability. Designed for pre-press, digital photography, video editing, and post production work, this 24.1" LCD monitor houses a calibration device in its upper bezel that swings down at user-scheduled times. This eliminates the need for a third party external calibration device which must be manually placed over the monitor’s screen and then removed again every time calibration is performed.

Using either the OSD menu or the bundled ColorNavigator software, you can schedule the ColorEdge CG245W to self-calibrate at a specific time and at specific intervals. You can even schedule calibration for outside of work hours when your computer is turned off and you are no longer present. Since the PC itself is not necessary for self-calibration, the ability to calibrate the monitor is not dependent on using an operating system supported by the ColorNavigator software. Therefore, a calibrated ColorEdge CG245W can be used with Linux even though ColorNavigator currently does not support this OS.

The panel used offers 10-bit colour support when using 10-bit content, graphics card etc. For this you must also use the DisplayPort interface since the DVI interfaces are limited to 8-bit colour depth.

The screen features Eizo's 'Digital Uniformity Equalizer' (DUE) which helps negate fluctuations in brightness and chroma across the screen area. DUE utilizes the monitor's 12-bit look-up table (LUT) with an extensive palette of 4,081 grayscale tones for each R, G, and B, and internal calculation accuracy of 16-bits. This ensures a Delta-E difference of 3 or less across the screen. There is also factory adjustment of gamma, a 3D LUT for better additive colour mixture and several other high end features.
