I have bough a Dell u2414h because it's flicker free (my eyes are very sensitive to flicker). The problem is that i have done a video with my iphone 5 and the screen flicker from 0% to 100% brightness. Do you think it is from the iphone camera or there is a problem with the monitor? I connect the monitor with hdmi cable to a 5 year old laptop. I also install u2414h latest drivers for windows 7 64.

Video from my new u2414h flickering.
