Okay, I've been playing with my 3008 for a full day. It's going back to Dell. The screen is full of dead/stuck pixels. I stopped counting at 50 and there are a lot more. A few comments:
1. Brilliant colors out of the box without any calibration
2. The monitor displays HDTV extremely well
3. I tried several games to test for input lag. My observations are based simply on what I saw with my own eyes.
Is it unusual for some games to show lag while others don't? I've got friends over to watch the games, so I'll post some pics a little later tonight.
- Dead Space: Noticeable lag
- Left4Dead: Less lag than Dead Space; had to scale back the graphics settings to get smooth gameplay
- The Witcher: No lag
- Mass Effect: No lag
- FarCry 2: No lag
- Deus Ex: No lag
Yes I would send it back just for the bad pixels.
Just curious on which video card you are using? Is it enough to handle the 2560 resolution?
EDIT: Uh never mind about the video card I see in your profile you are using the GTX280.
