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?
