I have a TV connected to my NVIDIA card. it worked well on slackware 11, but after i installed slackware 12 somthing is broken. the screen looks normal on the tv. but when i watch a movie in fullscreen it somehow streches the part of the picture to the right side of the screen and bottom, so i can't see a part (~20%) of the picture.
tried differetn versions of NVIDIA drivers but with no luck. i even changed mt video card to a newer one but still no good.
is that an xorg problem? how can i upgrade xorg if there is no other way?

You may have to play with the resolutions for monitor and tv. I have to change both to 1024*768 or I get the problem you describe. It does mean that the monitor is not very usable while watching movies. But it was like this in every version of slack/xorg I have used as far as I can remember.

i'm sure that it worked for me on slack 11, i have not shanged anything in xorg.conf.
gonna try changing the resolution.

I tried to change the resulotion to 1152x864 like my monitor has, the tv doesn't support it, but it worked, only in Xorg.0.log i found that it loaded mode "nvidia-auto-select".
the problem is solved with that. i will change the xorg.conf resolution for the tv to "nvidia-auto-select". i had no idea there was such an option

hmm actually you were right i still have the problem, only it's smaller didn't notice at first. but i still don't get it who is guilty for this? xorg or nvidia driver

Usually you need change monitor resolution to match the tv, but I will try doing the opposite like you and see if it works for me. Nice find if it does

*Edit: We posted same time. Ok the problem is caused because the TV-out (maybe tv too) can't handle as high a resolution as a monitor. Or at least thats the way its been. But I have to say that over the years the resolution handled by the nvidia drivers has changed a bit so maybe one day soon it will be possible.

Actually it should be up to mplayer/gxine to discover the size of display :0.1 and render the fullscreen appropriately.

Because they dont, I use a script that uses xrandr to change resolutions, play the movie, then change back.

can you show me that script? but it still changes the resolution on my monitor? maybe it's possible to somehow make mplayer get the correct resolution?

This is for playing DVDs but the xrandr bits are the ones you need.

I've asked on the mplayer mailing list about this. I will let you know here if I find anything.

Try using 'nvidia-settings' it may help configure it properly (has many autodetection features you may find useful).

There soesn't seem to be anything in there to adjust resolution, just info. I actually stopped using twinview in favour of xinerama. It may be worth trying it out again to see if there is a difference.

There should be "X Server Display Configuration".

Ah yes, well there would be but I turned off dynamictwinviewinfo. Will turn it on and see...

hmm, hinerama helped with the cut off picture problem, but now when i watch movies the sound goes faster than the picture. + some applications open on my monitor and some open on the tv.
i think i'll stick to missing 5% of the picture for now

You can try to renice the process with a higher priority.
