tv-out problem geforce 4 ti4200
 

as the header says i am having a little bit of a problem managing to use my tv as a monitor. i can get the image out to the tv, but the image is black and white and i can't get the resolution to fit. The tv is using pal-b and it works fine in windows. what could be the problem?
i've tried some gui-programs to make it work, but without success. i'd like a link to some kind of guide how to set up xf86config or something like that, just general guidelines. if i set up the tv in xf86config, how do i switch between the tv and my default monitor? how does "twinview" work? where can i find horizontal and vertical frequencies for my tv? everything is appreciated.
thanks in advance.
