R9700 tv-out

edited July 2003 in Hardware
I have connected my R9700 to my old tv.
I have connected it with a s-video cable and a s-video -> scart converter.
My tv is quite old therefore it lacks a seperate s-video input.

So far so good.

But the Radeon will not detect the tv.
I have read that my tv might lacking a certain component that indicates that a tv is at the end of the cable.

Is there any way to get around this?

Can I use an other tv-out utillity? And would it help?

    I dont know about anything that would detect a signal from the TV. It sounds like you may be having a software problem? Could you verify that the TV works with a newer TV?

    I'm not sure about that card, but have heard of some people manually setting the second monitor to "TV" in that situation.

    Will the R9700 let you do that?

    ATI TV-outs auto-sense for a TV connection to determine whether or not to initialize that screen mode. What they look for is a standard 75-ohm resistance level on the line. If the 75 ohm level is there, it recognizes a TV and gives you the option to enable it. If it does not find that resistance level, then you it assumes you have no TV connected, and you cannot intiialize the TV out. So I am guessing that somewhere along the line you have no 75 OHM resistance return to the card.

    A SCART convertor should maintain the 75 Ohm resistance level. Now, we don't use those in North America, so how does the SCART hook to your TV? Does it plug directly to the TV, or do you use another video cable to get in to the TV? Is it a composite connection? Or is it RF? Do you know the model of the SCART connector? Can you post a link so I can check it out?

    The scart is directly connected into the telly. I can use both svhs directly and with a scart adapter without any problems.

    MJO,

    Have you actually pressed that "power" button in the display propertys? I forgot to do that first and boy it took me a while to notice it. In many cases, the pc needs a reboot when the channel is chosen on the telly. Where is the videoccard bought? If it is bought in a country where they use the NTSC tv system, you
    MIGHT have to change it to Pal in the bios. My card worked a lot better when i did anyway. Make sure the display propertys is set on Pal B.

    I got it working.
    On the screen with monitors there is a button called troubleshooting.
    There you can force detection of the tv.
    Now I have picture on the tv but it is not very sharp.
    My old geforce had an option called flicker something, that made the picture look much better.

    I need a new telly, this old POS is no good.

    ATI has options for sharpness, flicker removal, etc. if you click on the TV monitor properties in the display control panel.


    Mack, it sounds like the SCART is a bit of a pain as far as TV-outs are concerned? Have you ever tried taking the S-video out of the video card and putting it through an inexpensive Distribution Amplifier? That would probably give it the 75 ohm resistance no matter what it is connected to. I have played with this in NTSC land with a composite out, put it to a $50 Radio Shack DA, then it didn't even need to be connected to a TV to auto-sense the 75 ohm resistance level. Works great if you want to plug the TV out into some non-standard gear.
