I have this monitor. I watch movies/tv shows on it, in the dark, (I doubt you will be watching as much as I do) and I have no issues with any backlight bleeding. There is no backlight bleed.
I think the problem is that there is a quality control issue where some monitors are slipping through the net, that have problems with them. But, if you get a good one, then you wont be dissapointed (unless of course, you expect CRT performance ).
I believe others have stated that games run fine, even at the high resolution required for this monitor, using a 8800GT video card. However, if you feel that the frame rate is too low, you can always run the monitor at 1680x1050, to play games. At this resolution, games still look pretty good. In fact, somebody earlier in this thread stated that they forgot to change the res back to native res and played using 1680x1050, without even realising.
So will a game like Crysis run smooth and good performance? And will COD4 on highest settings run with high fps on 1900x1200?
Are the current ones still shipping with the odd issue are has QC picked out all the dodgy ones?
Cheers
