I just bought a Dell Inspiron bundled with the E2015HV monitor. The picture quality and color/contrast is terrible though. The picture always looks kind of bright and foggy. Like there's a constant glare (making blacks more of a gray, lighter colors too bright), but nothing I do seems to fix it. I installed the correct drivers and everything is up to date, I've run diagnostic mode and just tried to adjust the brightness/contrast manually. The brightness/contrast really doesn't work, the problem persists, everything is just dimmer.
On top of that, pictures are fuzzy. If you open a picture file it's not terrible, but more fuzzy than it should be. Smaller pictures, like thumbnails or iTunes album artwork are really blurry.
I currently have my old AOC monitor hooked up to the machine, and it works fine. Colors and picture quality are as they should be.
