How do I force my ATi Radeon 9600XT card to display on the TV at 50 hz?

I recently installed a ATi Radeon 9600XT graphics card in my PC with the intent of using its TV-OUT to watch films and stuff on my TV, but I only have a PAL-i 50hz TV. The graphics card thinks that the TV can handle 60hz and defaults to that, without (seemingly) any way of changing it. This results in a nice B/W image on the TV, which isn't much good. Anyone know how I can force a 50hz signal on the S-Video out of the card?

PAL I standard is 625 lines at 50 Hz, so that is what should be supplied via the S-Video connection. I believe that the problem is usually old TVs/VCRs which are not compatible with S-Video, or NTSC output selected for the graphics card, instead of PAL.



My PCs could not display colour on old TVs via S-Video, but did on new ones. In one case, the graphics card had a video out RCA type socket. This produced colour via a SCART adapter. My latest Radeon X800XL has a S-Video to RCA Composite adapter cable which, I suppose, would work via that SCART or in a TV with RCA video socket.

I don't think its because of the refresh rate.



Look into the S-Video connector in your S-Video cable. How many pins do you see? Then look into the S-Video port on your graphics, how many holes are there?



I also have an ATi card (Mobility Radeon X700), which has a 7 pin S-Video port. I tried using the 4 pin S-Video cable I got with my older NVidia card. The same BW image.



So what you need to do, is buy the right cable.
I think it will still work. The difference is only in reftresh rate !!!!
