I put my TV (42" G25) up in the bedroom and tried my go to surround sound demo disc, Master and Commander.
The sound was great, but the tv looked terrible when the ship went into the fog at the end of the first battle. Lots of banding in the grey. I don't recall seeing that before. Currently it's paired with a Pioneer receiver and Panasonic BD via hdmi, thx setting (unmodified).
I will rerun it on my main theater and see how it looks on my projector and LG plasma.
I don't recall ever seeing pq problems like that when it was with the projector (LG bd, Yamaha receiver, Mitsubishi projector) but I may not have tried it with the tv. I generally watch movies on the 106" projector and use the tv for cable during the day.
