ltgary should see this issue if there since I have tried almost every setting besides going in and messing w/ the colors.. ISF mode 2 seems to work the best so far..
It only seems to happen when an all white screen comes up it fluctuates from a light white/blue almost to dirty white.. fast hard to see once in a while but still a distraction... 240hz seems to pause sometimes or jump, almost feels like lag.. When compared to the samsung 52a750 side by side the 120hz a750 seemed alot more smoother and also handled fast moving images better...But also had more blur on 120hz Samsung..

Glad I have three xbox's and a BLockbuster account
All of these games were tested in standard pic mode on both sets w/ 120hz low and 240hz low+ local dimming..
Both xbox's were set to intermediate refrence levels and tv HDMI black level to Normal/High same thing different models.
Note: No matter if its watching TV or playing games.. Back light fluctuation and 240 hz issue still there
