Just got the Samsung LN46A550 and tried to output to it first from my computer using VGA. This worked but the screen was too big and no settings would get it right. So I have a HP laptop that has HDMI output on it so I used this and am able to get the screen at 1080p but its a little hazy and is too large so about a 1 inch border cannot be seen all around the picture. The chip in the laptop is Nvida so I used the Nvidia control panel that had several functions for HDTV signal and scaling. After trying everything I could set in there, I still cannot get the picture to perfectl fit the screen in 1080p. Any tips? Thanks in advance!
