I am not feeling bad about my purchase but sorry your not completely happy with your tv, maybe the tv, cable or input is bad itself? I have been reading through the forums for a while and have not seen many issues with the Sony vs the Samsung. I have played the same game with Xbox 360 and have had great PQ experience with great colors, low input lag and good black levels (brightness levels up for game mode).
also, did that setting change help your PQ for normal tv/movie viewing?
The picture is certainly brighter than it was before I disabled that. I haven't had a chance to game on it yet tonight. I have not noticed the banding tonight either but I do see a lot of ghosting.
What PQ settings are you using? For normal tv viewing I'm using CNET's PQ settings.
