I didn't notice this on my 22" dell until it was calibrated but it is rather disturbing....and apparently is common on these lower end monitors. The top 1/4 of my monitor is much cooler color temp wise than the bottom 3/4ths. It doesn't effect my processing at all if I am careful but it is annoying as fack to look at. Anyone else noticing this same issue with their lower end Dell LCD's?
Haven't noticed it on my 20" 2001WFP Ultrasharp, but I haven't been able to calibrate it since I went to Windows 7 either.
The bottom 3/4ths of my monitor is dead on at least lol. I doubt you will notice an issue on an Ultrasharp.
