Nvidia TV-OUT help needed


NEWB ALERT NEWB ALERT. Right here goes.

I have Ubuntu 10.04LTS installed and want to get TV-OUT working so I can watch movies and stream media from the internet to my TV.

The hardware I have installed is:

Nvidia GeForce2 mx400
TV is an old analogue CRT one

I know its an old graphics card and TV but the whole computer is put together from spares I have knocking around.

So I have Ubuntu installed and the Nvidia proprietary drivers installed, version 96. Through the nvidia-settings application I have managed to get a picture in colour onto my TV screen, but the problem is there is about a 2 inch black boarder around the screen and also like a grey shadow over the entire screen.
So I tried the NVTV application, the same thing happened again with the black boarders around the screen but the grey shadow over the entire screen had gone, so the black boarders are actually black and the colours show up properly.

So is there a way to get rid of the black boarders and grey shadow (if it decides to show up again), I am a total newb to Ubuntu but loving it so far and this is the only problem I am stump on so far.

This is my X Config FIle I have with all the settings I have to get to the above point:

# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings: version 1.0 (buildd@palmer) Fri Apr 9 10:35:18 UTC 2010

So if anyone is willing to help me out on this matter it would be great but please remember I'm new to Ubuntu.
Also if any more information is needed from me please ask and I will try my best to get it to you.

Looks mostly right on the config.

what does this show you?

$ xvidtune -show

If it shows two displays, then you should be able to use the other screen. If you haven't restarted X since you changed it's config, now would be a good time to do so. Bear in mind that in a lot of cases you need to have both displays ON and CONNECTED when you start X to have BOTH screens available. After that it's just a matter of how to use it. TV out so I'm assuming standard definition (SD/640x480). Perhaps this will let you use it:

$ mplayer -ao alsa -vo x11 -display :0.1 -vf scale -zoom -x 640 -y 480 ./media.type

Many of the applications have the -display option so it's not unique to mplayer. Baring that setup some sort of xinerama / clone / whatever configuration suits. Since the TV is not the default display it might take a little effort to launch your browser or other app on that display. But it can be done. Even if you have to go old school and just change the DISPLAY variable on an xterm. Many means to an end. NVidia has some sort of TwinView setup with multiple displays that is unique to NVidia so if you're still having issues, google on that.

Thanks for your reply:@)

Ok the result from: xvidtune -show

"1024x768" 65.00 1024 1048 1184 1344 768 771 777 806 -hsync -vsync


and from: mplayer -ao alsa -vo x11 -display :0.1 -vf scale -zoom -x 640 -y 480 ./media.type

All it does is start mplayer and plays a file but it doesn't get rid of the black boarders around the screen or the grey shadow over the screen.

On the screen that appears on my desktop everything is ok, I can launch the web browser and also vlc media player. All that is wrong is the black boarders around the screen and the grey shadow over the full screen.

is their anything else i can do do fix these?

xvidtune should have shown TWO entries.

Check you /var/log/Xorg.0.log to see what happened.
