I had no idea, but apparently this "overscan" thing is a perennial annoyance when using HDTVs with computers. For my TV, overscan was "on" by default. I had to set the video out on the computer to 1920x1080 and then (only then and not before) go to the "advanced video" settings on the TV and set overscan to "off." It looks like I'll only have to do that one time. Now when I use 1920x1080 it all fits on the HDTV screen and it looks just right -- I have achieved the coveted "1:1 pixel mapping." The only problem is that if I restart the computer it comes up with 1680x1050 for that monitor every time. It's as if the /etc/X11/xorg.conf isn't enough to convince it to change to 1920x1080. One of my current guesses is that the TV is, for some reason, reporting itself as 1680x1050, maybe because it was in that mode earlier. I don't know. Another good possibility is that the configuration is stored in places other than /etc/X11/xorg.conf -- is it? This is a relatively small problem because I leave the computer on most of the time. In case others have similar problems - My TV is one of the 42" Insignia sets from Best Buy and I found this page to be pretty helpful: http://community.insigniaproducts.com/insignia/board/message?board.id=discussions-televisions-en&message.id=132 Mike
