Can't get tv out to display at a proper resolution on my tv (svideo)

mr-t · 01-11-2008, 01:15 PM

Hi,

I need help with my xorg.conf. I'm currently in the process of setting up tv-out on my gforce 8500gt using svideo. I've set up twinview (in clone mode) and got my desktop to display on my tv. Unfortunatly only one part of my desktop is showing. All I can basically see is a large chunk of the middle of my desktop (around the size of 640x480 window) and I can't get a higher resolution using nvidia-settings or manually editing the xorg.conf.

Heres a copy of my xorg.conf:

Code:

# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings:  version 1.0  (buildmeister@builder3)  Wed Sep 12 14:30:30 PDT 2007

I've heard from my other thread on the official ubuntu forum that my xorg setup is slightly dodgy. Any ideas?

154 views and no one has any clue???

I think this might be a problem with ubuntu, i've found countless threads like this all over

Your TV seems to get incorrect signals.

This is what I have in my xorg.conf for my TV:

Code:

Section "Monitor"
        Identifier    "PAL TV"
        HorizSync      30-68
        VertRefresh    50-120
 EndSection

If you have NTSC you need different settings.

Sorry, can't help you more.

mr-t · 01-17-2008, 11:30 AM

Funnily enough that has slightly helped. I can see more of my screen. Btw i only changed the horisync and vertrefresh values. How big is your tv? does anyone know the correct values for a 30 inch crt tv?

dive · 01-17-2008, 11:33 AM

That info is usually found on the web. What make and model is it?

mr-t · 01-17-2008, 01:59 PM

It's a Samsung Ws28m64.

fragos · 01-17-2008, 08:56 PM

You need to determine if your problem is with the TV or does it relate to dual monitors. Can you get it working if the only monitor is the TV?

mr-t · 01-23-2008, 01:36 PM

Nope, its the same either way. I'm trying to clone not dual screen.

You don't seem to have any modes defined anywhere.

Might help if you put some in:

Code:

 Section "Screen"
      Identifier     "Screen1"
      Device         "card1"
      Monitor        "Monitor1"
      DefaultDepth    24
      Option         "NoLogo" "True"
      SubSection     "Display"
          Depth       24
          Modes      "1024x768"
      EndSubSection
 EndSection

For example. You might also be able to use nvidia-settings to set up your twinview.
