Thanks for the input. Being unfamiliar with HDTV's, the backlight setting was the one that was giving me the most questions. I am trying to have a normal HD viewing setting (with my Fios HD), a Movie Setting ( for DVD's and Blue-Rays over my PS3) a Game setting (PS3) and a Sports Setting ( for watching Hockey). I still have not yet connected my laptop. i am waiting for the new VGA cord to be delivered (no HDMI on my laptop).
I do get a significant amount of light in the room (one wall is all windows) and lamp light at night. During the day, the glare on my old CRT was so bad we would have to shut all of the blinds in the room as well as the curtains over the sliding door in the kitchen. I found that keeping the backlight in the 60's offers me my best picture.
Now I need to figure out the effects of noise reduction, MPEG NR, Luma, Smooth motion. This can be a little mind boggling trying to figure out how each one actually impacts normal viewing vs. sports viewing vs. movie viewing vs. gaming.
