No Blu-ray yet so these are from SD Upconversion Sources:
These are my settings that work best from 3 sources and streaming video(Hulu), in a lightly lit room.
Resolution set @1920x1080 from all sources.
I know the set is 720p however, inputing 1080p delivers better PQ.
1-WDTV - Nice PQ but the navigation needs work. Returning it for now.
2-HTPC 8600GT-w-nVidia PureVideo - Several Software Players
-Hulu is outstanding, again @1920x1080
-Of the three sources, the htpc has the worst PQ unless streaming from Hulu. Still working on it.
3-Philips DVP5982/37 I'm sure there are better upconverters out there, but the 5982 is amazing.
One other note, I had an Olevia 537h that was considered one of the best SDTV's and the Sammy blows it away.
Settings: I used Televisioninfo's
calibration as a starting point.
Picture Mode: Movie
Black Tone: Off
Dynamic Contrast: Low
Color Space: Auto
White Balance: ---
Flesh Tone: 0
Edge Enhancement: On
Color Tone: Warm1
Size: Screen Fit (Even 16:9 is a slight zoom feature that distorts the image)
Digital NR: Off
*HDMI Black Level: LOW
The WDTV and DVP5982 are grayed out, but the black levels by default are very good for both.
If the PC is set to Normal instead of LOW, everything is way off.
