I have a question about my new 20" Apple Cinema Display. I'm looking at this screen and one side has a slight cyan tint to it and the other side has a slight red tint to it. It really makes grays and whites look odd. Is this a defect or is this acceptable? Should it be one solid shad the whole way from left to right? If not, can I return it for another one? I'm running this display from my PowerBook G4 1GHz with only 32MB of VRAM. Could the video card play a roll in this?
