Try as I might, I just could not get the picture to look right. Too dark, too light, washed out, too red etc. This was on the "user" mode.
Then, I re-read the postings, and switched to "game" mode. What a difference. It's actually a real pleasure to watch now... more tweaking I'm sure, but for me, a great starting point:
CMS HUE/SAT/VALUE: (default)
COLOR TEMP: low
MOTION ENH: off
ACTIVE CONT: on
FILM MODE: off
DIG NOISE: off
The above works for me - you may, or may not, have the same results.
