Greetings,
I bought a U2414H monitor last year and I noticed something a little odd about it. If you look very closely you can see this sort of fuzzy pixel effect on any solid colors. It is very subtle so you must look at in the dark. When there is a dark scene in a game, you can definitely make out the green/red dots over any solid colors. It is hard to describe as I have not seen the issue anywhere else. I know it is a problem because I can not reproduce it on my friend's monitors, and he owns three of them.
The issue occurs on HDMI or DisplayPort. I know it can not be the computer because it also occurs with my PS3 connected over HDMI. I don't think it can be my amplifier with HDMI because it occurs over DisplayPort. My HDMI and DisplayPort cables are not dirt cheap and they are different brands.
I can take a lousy picture with my iPhone 4, or I can have my friend take a high quality picture with a camera.
