Okay, so I have the new Quad 2.66 mac pro with the GT120... I have had the 30" ACD for awhile now, but just yesterday I added a 20" ACD, via the DisplayPort to DVI cable then to the 20"... The 30" is a direct DVI connection... When I put a finder window that splits in between the two screens, which are side by side, the whites on the 30" are a little more yellow and the 20" they are more grey than white... What gives? the 30" is at 2560X1600 the 20" is at 1680X1050 Is this normal?
