Nvidia Geforce 8400gs Overscan Issue

Asked by Matthew

I have a problem with the overscan on my Nvidia Geforce 8400GS. I did some research and I noticed other people have the same problems. It only occurs when I install the restricted drivers from Nvidia. Is there a way I can fix this in Ubuntu 11.10/12.04?

If you run:

sudo nvidia-xconfig; gksudo nvidia-settings

You can set the res and refresh rate to something and click 'save to x config file', you can then run:

gksudo gedit /etc/X11/xorg.conf

And set the resolution to what you should use with your screen. May help

No matter what resolution is set the overscan makes the image to big. I need to figure out how to disable the overscan all together. Normally you use "PC Mode" on HD Tv's, but for some reason that option is greyed out. This is a 42" Phillips HD TV

Does the screen have an OSD you can play with. It may need tweaking

I don't think so. It's very limited to what I can do. In Windows 7 if I switch the graphics to 720p it works correctly. How do I do this with Ubuntu?

Fixed by using the overscan slider on the Nivida-Settings tool. Hope this helps anyone else who might have this issue. It's easy to overlook it so please check closely. :D
