Hi, my original thread died, I was getting no replies. So I am hoping to illicit more responses.

My friend has a 29 inch TV he usually connected his windows machine. Now that I have persuaded him to switch to PC LinuxOS 2007, he cannot get a display on his TV. Seeing that his regular 14 inch monitor works in PC Linux, I figured it had to be with his cable. But he bought a new one and it still not working.

It had been suggested this might be a linux driver issue.

Another forum user suggested I paste the result of $ lspci | grep VGA

01:00.0 VGA compatible controller: nVidia Corporation NV15 [GeForce2 GTS/Pro] (rev a3)

How does his TV connect to his graphics card? VGA? S-VIDEO? Composite?

What driver is being used for the graphics card?

Thanks for replying. The cable is purely VGA. It does try to load kde and we do get the kde login. but when it tries to go into desktop it seems to loose signal. We don't even get a console. However the same thing connected to a normal 15 inch monitor goes straight into KDE.

Regarding the drivers, the only info i can get is via that earlier pci command. lspci | grep VGA the results of which you can see in the posts.

How can i get more driver details for you?

If the monitor is connected via VGA, then I would look at refresh rates and other parameters to see if they are within the guidelines of the TV. (Though the fact that the login screen works seems odd -- I would expect X to either work or not, unless it is setting a per-user resolution.) If you run 'xrandr --verbose' in a console it should show both the horizontal and vertical timings that are set for the graphics card. You'd need to compare those to those that the TV uses to see if they are within spec. (Also, consider trying a lower resolution, some TVs do not scale resolution and thus expect output at a native or common resolution.)

ok, that i will check that. but how do i check the TV's refresh limitations?

Here is the result. I am going research the TV's refresh rate.
