Do you have problems looking at modern LED LCD monitor for extended periods of time?

Eyestrain, dizziness, headaches

Extremely interesting read. After my old Dell 2209WA became defective, I tried to find a new monitor I could use. To my surprise, I have found out that the modern LED monitors are extremely unpleasant to look at, and I started to look for the source of the problem. It seems that all the flickers PWM and temporal dithering introduce to a computer screen is very harmful for the neural system - at least in case of sensitive people, and long-term. 

 

Do you have a similar experience?

Lost my old 17inc LED Phillips monitor in the Christchurch Earthquakes ( it could even do 75hz which seemed alot nicer than the 60hz it could do. The new ips one only seems todo 60hz.

As I wrote in a PM to you, my new CCFL Benq G2420HD is just fine. It's not perfect, it has all the TN monitor drawbacks, but it induces absolutely no eyestrain, unlike all the LED panels, and I game on it for hours regularly.

I recommend a German site prad.de (most reviews are in german, use Google Translate if necessary) - they started to include "backlight" section into each review, measuring the PWM flicker with osciloscope and providing accurate information about its characteristics.

The one monitor that should be satisfactory is HP ZR2440w - it features over 400Hz PWM duty cycle, which should provide comfortable and stable image. It's not exactly a gaming monitor, though, due to the high resolution (1920x1200) and rather large input lag, but for strategy games it may be just fine.
