Hi all. Running XBMC on Linux Mint 11 with a GT430 nVidia card. I have the latest proprietary driver installed and activated (302.17). When the resolution is set to 1920x1080/60p, everything is perfect, no overscanning, 1:1 pixel mapping. Razor sharp images. However, when I switch to 24p or 30p, the TV overscans about 10-15% resulting is a crappy blurry image (but with less judder, woohoo). There are no settings in the TV menus as far as I can see to control overscanning. I've looked through several times. There's also nothing in the nvidia configuration panel dealing with overscanning.

I'm pretty sure this a lost cause, but does anyone have any ideas?

Well ****. Never thought to look at my remote. "p.Size" is apparently pixel-size. Pressing it a few times changed the pixel mapping to 1:1. Who would ever want to overscan on an HDTV?

Overscan was required on early CRT TVs since the screen image would shrink over time. Therefore TV programs and movies were all made with little or no meaningfull content within about 15% of the edges If overscan on the TV's was not disabled the physical size of all meaningfull content is larger so many people prefer not too disable overscan.
