Thought I might throw my settings out there, not to imply that I think anyone else should use them, but I spent a lot of time getting my display to look correct with my source material via my connection, and I think the result is great. I make no claims that these settings will reproduce acceptable results on anything else.
I was calibrating my HLT-6756W to display my Xbox 360 via VGA at 1920x1080 @ 60 Hz. I started with Avia, had less than stellar results, used the test pattern on the NBA Live 07 Demo, then watched a complete HD-DVD and paid attention to what I thought was off. Then I used the HD-DVD (Smokin' Aces) mostly to get flesh tones correct and learned that Avia's test pattern brightness setting was too low for actual viewing. After setting things by look I went back to Avia and had much better results. I tweaked the brightness and contrast, and adjusted the white balance. Then it was back to Smokin Aces, then King Kong, where I continued to try to balance realistic flesh tones with good color saturation. I ended up giving it a bit of green tint to compensate so that I could keep color high enough for acceptable vivid colors. Last, I viewed two 720p videos (Gears of War promotional ad and Halo 3 TV commercial) to test the final product. It looked 10 times better than when I viewed them with stock settings three days ago.
Sharpness is still elusive. I looks to have little to no effect.
Colors gave me fits until I set color gamut to normal . I switched it and said "Huh, I guess the Samsung menu bar is supposed to be blue. Hadn't noticed."
I adjusted white balance because my whites looked just a hair too yellowish. This setting evened it out nicely.
