First of all congratulation to your test.
I would like to ask you a little bit more detailed question about the LED backlight of the new DELL U2412M.
I am to buy an IPS DELL monitor. But, what I am afraid of is the PWM control (Pulse Width Modulation) of the new LED backlight technology.
There are a lot of sites on the net which say, that the high- or not-so-high-frequency flickering of the LEDs (due to this PWM LED control) can cause serious eyestrain, or even worse, migraine, even if you cannot see it at first glance, at all. I have not found any test site yet, which tried to investigate this problem of the new technology.
Do you happen to know, what PWM frequency does the LED back-light of this new monitor operate on?
Have you felt the U2412M more tiring to the eyes compared to the U2410?
Thank you for your help for advance.
