KDE and Nvidia-settings dont play nice

I am trying to configure graphics for a friend of mine. He is running fc6 kde and an nvidia driver. He has a plasma tv with a max resolution of 1366x768 the model is visio p50hdm if that helps. Anyway I can get a picture on the tv, but it is partially cut off on the right and left sides as if it were to big for the tv. the resolution is set at 1280x720 automatically by the nvidia driver and will not go to the max 1366x768. I tried adjusting the resolution with nvidia-settings, but if I lower the resolution the graphics get larger, and still do not fit the display. I tried a modline in the xorg.conf file, but when I restart x it loads, then crashes. I know I am doing something wrong. I looked at some sample xorg.conf files, but it looks like they are geared toward the older nvidia drivers. I am using 9755. Any help would be greatly appreciated. Below is a copy of my xorg.conf

It looks like you may need to configure some of the nastier settings in xorg.conf. Things like horizontal refresh rate and vertical refresh rate and other stuff like that. Happily this information should be in the user manual for the television. There should be one or two pages that have all of the technical specifications.

Or ...

You could temporarily install OpenSuSE. They have a great utility for setting up the xorg.conf file. The utility is called SaX2. You could run that utility, get the xorg.conf file, then put that in your Fedora system. I think that's what I would do.
