Yeah, I have definitely determined that differences are right in the
displays, so not my card, cable, etc. I did try them as individuals and even
swapped position on the cables and the color stayed with each display. It's
not so bad though that their is any kind of 'wow' factor or anything. Guess
I was just sorta lucky before, two totally different displays (even
different geometry) and color differences were quite subtle.
