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

Question

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?

Answer 1

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.

nicely, you should continually circulate to the ATi Radeon snap shots card internet site... possibly they might have snap shots card drivers... Google is your pal, you may save your self countless time in case you only typed in ATi Radeon snap shots card drivers.

I think it will still work. The difference is only in reftresh rate !!!!
