Can't get above 480p on HDTV (7.10)

**DoddyUK** · May 8th, 2008

Hi. I've got a HDTV which I can't seem to get to run at a decent resolution. No matter what I do, I can never seem to get it to run at anything other than 720x480, despite my Windows partition running fine at 720p (1216x684).

I'm using a Goodmans GTVL19W17HD and an Nvidia GeForce 6200, with the two connected via a DVI-HDMI lead. Nvidia-settings doesn't offer me a resolution above 480p, and I've messed about with xorg.conf so much with no success. Here's my current layout:

Code:

I'm currenty running this on twinview with the VGA port on my HDTV (though this is limited to 1024x768) but I would like just to use the DVI port once I can get this resolution problem sorted. Thanks.
