How good and how stable is NVidia's driver functionality Twinview? Do you have to use the same resolution on the monitor as you do on the TV? Do you need a card with 2 heads to be able to use different resolutions on the monitor and the TV?

Rock solid on my Mx4000. I use i for TV out to watch films on the w/s TV in clone mode. Very carefully read the NVidia readme file/manual as it tells you everything you need to know.
Here's my xorg.conf if you wanna crib a little

Code:

I agree, I've used it for three years without problems.
You can have different resolutions on monitor and TV, and of course you need two "video heads" - I have only used one card with two connectors (vga7dvi/svideo) but two cards should work too?
The only thing that doesn't work (AFAIK) is using all three connectors at the same time.
