Send the tv a 720p signal using a ps3/xbox/blue-ray player/upscale dvd player or whatever you have that you can manually choose 720p
After doing so go to
Picture and Display -----> Screen Settings -----> Display Area
See if it lets you choose Full Pixel in that option menu
The options should be;
The manual says that "Full Pixel" is only available with 1080p/i
I find that hard to believe since the S and V series is able to do it with 720p also.
The reason why i am asking is because some PS3 games are only in 720p, and i cannot stand overscan. I want a full picture with nothing chopped off the sides.
