I picked my 77" C1 and just got done setting it up. Sadly, the amount of vertical bands is extreme....I mean really bad. There are streaks all over the screen with some brighter ones on the left and right side of the screen. I am going to run the set for a few hours and do a pixel refresh, but initial impressions of the 77" is god awful. Probably one of the worst uniformity sets I have even seen. Hopefully it can clear up...because the image is great when on a bright seen and the banding is not visible except for the very strong one on the left side of the panel.
