how make X display smaller on TV

[jjgitties]

hello, i am trying to setup my computer to use my tv as a display. it works but i think something is wrong. the screen is too big on my tv. how can i make the screen size smaller so it fits?

i tried to change 720x480 to 710x470 in all the places in the xorg file and rebooted but it still not changing anything. it looks the same. is there something else i am supposed to do?

below is my xorg file.

thank you.

Did you ever get this working properly? Your post is old but I've purchased a pvr-350 used for mythtv and am trying to get F10 to output Xwindows to it. Right now I only get the mpeg-2 decoding so I only see the films/recordings...no menus or anything else.

I've just installed the x11-ivtv-driver and am trying to see if that is what I'm needing to implement.

Thanks for posting your xorg.conf contents...it'll give me a starting point at least.

Kindest regards,
kkjensen

Hello:
No idea which 3rd party video driver you are using, however, try having a look at.
Option "TVOverScan"

Google for more information on the option.
