I attached a jpg of a doctored screenshot, but basically I just built a media pc that works great. I'm using HDMI to my TV which ubuntu detected the resolution at 1280x720, my TV detects it as an HD signal, but hopefully you can see from the image the issue I'm having.

If not then I'll try to describe it.
Basically the edges of the screen seem to be chopped by just a few millimeters. I've gone through the screen resolution settings and the only options are the HD at 1280x720 or super low 6??x480 I think. The other options are 800x600 and typical 4x3 resolutions. The weird thing is when I went to screenshot it to post here, it took a perfect screenshot (screen intact), I had to doctor it in gimp to show what the issue is.

This is an nVidia 9400GT
Model: MSI N94GT-MD512

I'm using the 177 driver that ubuntu recommended.

Any help would be appreciated!

The folks over at http://www.mythtv.org/ have done a lot of work on this problem. I've had troubles with the HDMI interface of my nvidia card, and ended up using the YPbPr outputs instead. For video playback, myth can completely and finely adjust the over/underscan. I believe there are details on the same adjustments for HDMI in their setup screens. Granted, this is not for the main desktop screen, only the video playback. However, I have not seen more expertise with this problem than with the mythtv developers for obvious reasons.

ok, I'll look into this, hopefully if when/if I figure this out I'll come back and post the fix.

videohelp.com I think has the most gurus on this subject...
