When you bring the menu up, you can select Preferences. Under preferences you can select Normal, Theater, Memory settings.
I always leave Normal settings at factory defaults:
Flesh Tone On
These settings work good for 480P
(NTSC and Progressive Scan DVD)
For 1080I the settings have to be changed to correct the color from my HD6000. I do not know whether the correction is needed because of the HD6000 or the CW34X92. I use the memory selection in preferences to store these settings:
Color 60 to 70
Tint -15 to -24
Flesh Tone Off
The Color and Tint settings vary according to each movie being watched.
