Introduction

Flicker Free Database

Hybrid Backlight Dimming

Other Honourable Mentions

Please note: There has been a massive surge in the focus on ‘flicker-free’ monitors from many manufacturers since this list was first introduced on TFTCentral. As a result, the list is almost certainly not exhaustive. We will try to keep it updated for now, but at some point we will probably have to stop maintaining it. We will of course continue to mention whether upcoming models have a flicker-free backlight in our news pieces. We will also continue to test for this in our reviews.

Introduction

For many people, finding a monitor without Pulse Width Modulation (PWM) backlight dimming is now a key consideration. We thought it would be useful to compile a resource confirming all the flicker-free monitors we have tested, along with any others which we know of from other sources. Below is a table we will keep as up to date as possible, although note that it may not be exhaustive. If you know of any other screens which are confirmed as flicker free, please email or tweet us the details and links to the tests and we will get them added.

Keep in mind the varying testing methods used by different sites linked below and some possible margin for error. Those using oscilloscopes (TFTCentral and Prad.de) should be completely accurate, but those using camera based methods may be subject to some error for high frequency PWM.

Hybrid Backlight Dimming

Below are a list of models which are flicker free for part of their brightness adjustment range, but do use some form of PWM for other parts of the adjustment range.

Size	Model	Confir- med?	Source / Link	Date	Notes
22	Eizo EV2216W	No			Marketed as flicker free with "hybrid solution". Expected no PWM down to 20% brightness

23	Eizo EV2316W	No			Reported to be PWM above 20% brightness

Other Honourable Mentions

Below are some additional monitors which may be flicker free. This includes monitors which some reviews have tested to be PWM free, while other reviews suggest otherwise.

Size	Model	Source / Link	Date	Notes
24	Asus PA249Q	Prad.de	30/9/13	Not full PWM control, but some oscillation. Low chance of flicker and very high freq of 25Khz
	Dell S2440L	TFTCentral	5/10/12	Our unit and that tested by PCmonitors.info showed no PWM. Other reviews including Prad.de showed PWM at 360Hz. Possibly two versions?
	Dell UP2414Q			User reports suggest PWM free, untested by review sites so may be high frequency PWM control.
	Samsung S24A850D	Extrahardware	19/12/12	Not full PWM control, but some oscillation. Low chance of flicker.

27	Asus PA279Q	Prad.de	14/10/13	Not full PWM control, but some oscillation. Low chance of flicker and very high freq of 12Khz
	Dell UP2715K	Prad.de	12/10/15	Not PWM free, but very high frequency at 20.8Khz
	LG 27EA83	User Report	19/2/14	Possible new version without PWM as reported by user romkyns on Hardforum
	Samsung S27A850D	Prad.de	9/3/12	Not full PWM control, but some oscillation. Low chance of flicker. Also confirmed by Extrahardware
	Samsung S27B970D	TFTCentral	14/8/12	Prad.de test unit showed low amplitude PWM at 180Hz while our unit showed no PWM. Possible variation in units?

30	Lenovo LT3053p	Prad.de	18/11/13	PWM free, although some very high frequency oscillation, but that shouldn't be perceptible
