S-Video pc card?

i have an AGP8X Nvidia GeForce FX5200 Graphics card with connections, D-sub, S-video and DVI i have the cable for s-video but when i plug it into tv (24inch if it matters) all the writing on the screen is blurry and i can't change the refresh rate from 60hz and 1024x768 Res, what can i do??? thx|||DVI is a much higher resolution, so if your issue is w/ S-video and it's not working then DVI deff. wont work. Is just writing the only thing that is blurry or is the picture itself blurry too? You might have to try changing some settings on your TV to let it know your using a S Video connection. If no dice then you can always go talk to someone from Nvidia. Good luck man!|||well man try using the DVI cable, and if you cant i think your tv or whatever your connecting to cant support it
