there is also the under-scanning option which involved another option in xorg.conf and was set to about 0.7...i forget the exact name of it now but in essence it shrinks the picture to fit the screen.

You can also get at it through and look at the TV part.

Damn I love nvida :-)

Hmm, this looks like it could get complicated, lol

stuck at work at the mo, but will start looking into this when I get home..

Thanks for the suggestion

Please post your findings, as I am really curious if and how you succeed.

Meanwhile consider that if my "theory" is right, then the picture that the nvidia driver sends to the tv-out is already missing a part of the image (all pixels over 1024 horizontally and over 768 pixels vertically). And, if so, then there is absolutely no way to "recover" those missing pixels on your tv, no matter how you try (under- or over-scanning will not help either). It is not your fault; it is the way how the nvidia twinview and cloning options work.

So, I think you should try the only working solution: define two separate server layouts in your XF86Config file; one for you monitor and one for your tv.
