I'm looking for a monitor that does not make use of PWM (Pulse Width Modulation) For those not familiar with the concept here's a good article that describes it: http://www.tftcentral.co.uk/articles/pulse_width_modulation.htm In short its a technique LCD monitors use to control brightness (both LED & CCFL), basically controls the frequency at which the backlight operates. The reason I decided to look for a non PWM monitor is eye strain. I posted on here a couple of days ago and received lots of advice on how to reduce eye strain (lighting, flux, etc) - thanks to all who responded. In addition I decided to switch my monitor as I believe its PWM that irritates my eyes. Unfortunately monitor manufacturers do not yet publish PWM frequencies in spec sheets, and very few sites include this in their reviews during testing. I really hope AnandTech starts doing this soon, maybe a quick round-up on PWM/flicker tests of major models. Has anyone come across any monitors without PWM (continuous lighting) or really high PWM frequencies? So far I've only found reports of HP ZR2740w being "flicker free".
