Connection to LCD TV
« on: January 16, 2008, 01:29:07 pm »

I've tried to tie my pc to my new Sony LCD TV.

It's a triple boot WinXP/Kubuntu/Vector 5.8soho

WinXP: I see only the startup screen after that nothing, not a big problem, it's only Win.
Kubuntu: only graphical screens are shown, text mode like GRUB are not. but further on I can log in and it works fine.
Vector: nothing at all. So I reinstalled Lilo and it starts up in bootsplash showing fine. Than nothing, no loginscreen and by guessing "I should give my password about now" no image. TV shows "Buiten bereik" that  is Dutch for "out of reach".

Does anyone have an idea how to solve this?

"Out of Range" means that your TV can not handle the signal. The screen resolution and/or refresh rate exceed tolerances. Reason why you see text mode and some splash screens is because they are presented in a safe VGA signal. When X-windows loads, it kicks the display to higher values.

Check the documentation for your TV and find out what the native resolution is, and what refresh rates it can handle (60 Hz should be safe). Now hook a computer monitor up to your computer, and configure your video card to use those values. Then hook up the TV.

Thanks Nightflier, it gave me a shot to try. It worked ok but no 1280x768. Since I'm not that good with conf-files,  I just copied the xorg.conf from the kubuntu partition.
So I have 1280x768 but not 1366x768 if it's possible anyway.

To get 1366x768 you will need to manually edit the /etc/X11/xorg.conf file. There is a section that lists resolutions, something like:
        Modes      "1024x768" "800x600" "640x480"
Add your custom rez to all those lines:
        Modes      "1366x768" "1024x768" "800x600" "640x480"

You probably need a proprietary video driver to do this.

What kind of video card do you have? If it's Intel, you may need the "915resolution" package.

I use a Nvidia Geforce card with proprietary drivers, so it might work. I'll try to add this.
