TV OUT w/ ATI 9800 plz help!

[Fofo]

Sorry if this has been asked, but I have an ATI radeon 9800, can I have an S-video cable running from the vid card to my TV, its a 27" WEGA about a year old. The pic is fuzzy and blurry with lines. My guess is that this TV cannot support a high res, is there any other way to get the pic clear on my TV?

Thanks

It could either be Macrovision causing the problem, or maybe try 640x480 or 800x600 resolution?

Yes, I'm at the 800x600 setting. I don't understand why there is a TV out if the pic is fuzzy looking.

I wish I knew as well, I've got a zenith tv and a sony vega,
With my msi geforce 4 ti 4600 I get a fuzzy picture on both, I've tried my ati radeon 7500 on the vega and seem to get the same effect.
I'm assuming this must be macrovision causing this problem as both seem to have it in their drivers.

Is there something do do with overlay, or cloning perhaps on the 9800?

that's wierd. when i hook my g4mx up to the tv (without changing resolutions) everything looks fine.

What cable are you using and what driver for the video out?
Just the WDM 1.22? I've tried it and the MSI's own driver, even the catalyst 3.7 didn't help.

This is quite annoying, I've tried 640x480-1024x768, I'm not really sure how the ati card res get's up that high, my geforce 4 ti 4600 will autopan at that high.

Come to think of it, it can't be macrovision in the driver it seems, the ati card will give me a blurry screen on the tv when I enable it and can view the bios and everything else with out being in windows unless it's on the card itself.

Someone has to know the answer to this i'm sure.

I don't know how often this must come up until people get it:

The properties of the S-Video/RCA signal do not allow fine detail to be anything but blurred. Signal bandwidth is about 5 MHz, and it's running interlaced lines as well; not having separate lines for red/green/blue/sync just adds to the problem. Desktop and text display is never going to look anywhere near as nice as on a real monitor, where the signal bandwidth is from 28 (VGA) to around 170 MHz (1600x1200).

Look I had the same problem, I didn't know what to do, I switched on TV and there was some big color problem, and when I put NTSC it was ok but black n white,
so what you need to do is check something on your tv, it's no PC problem it's the TV you have to tune.

I connected to TV with s-video cable, and I watch it on channel 0 or AV, and on this channel I have the option when I go in the menu to choose AV or Composite Video, and I chose c-video and it worked- problem solved.
