Default HDTV problems

Hello All

I have a GeForce 9400 GT with, supposedly, HDTV capabilities. But the only HDTV output that will work is 480p. All of the other HDTV settings give a black screen. I am using a componet cable to connect to the TV. Also TVOverscan does nothing. I did read on another forum that TVOverscan is nolonger supported by NVidia but it is still in the read me so what gives?

Also if Overscan is no longer supported what was the last driver that did support it?

Does anybody have any info about getting other HDTV settings to work? Is this a driver issue or a card issue or what? If it's a driver issue what driver should I try? If it's a card issue how does one find out what settings work, or don't work, on what card?

It probably doesn't matter but I am using OpenSuse with 177.82 Nvidia driver.

Default Re: HDTV problems

I use my HDTV exclusively as my monitor. I have included my working "/etc/xorg.conf" file.
OS: Ubuntu 8.10
Kernel: 2.6.27-11
GPU driver: 180.22
I run at 1920x1080i which is the best my HDTV can handle.
I do not think my OS distribution or driver version actually matter as I have been running the same xorg.conf with previous drivers and kernels.

The overscan parameter is included but does not do anything as you had noted. Also my specific HDTV does not return valid EDID information so I have forced the resolution information. You will need to modify for your own specific needs but this is at least a working model to start from.

This reply does not seem to show the indentations/tabs that actually appear within each section of my xorg.conf.

Good Luck.
