50Hz or 60Hz ??? All In Wonder Radeon

Please bare with me on this explanation - there is a point...!

.... I have a AIW Radeon 32MB DDR Card.

When I have TV out working and have a look in the Display Tab in the ATI Display Settings it says my Monitor is working at 50Hz - and my TV is listed at 800 x 600 PAL I (which is correct for UK) -

however if I look in the Monitor Tab at the Refresh Rate options the card can only do 47Hz Interlaced, 56 Hz, 60Hz etc etc --- no mention of 50Hz.

If I look back inside the Display Tab TV settings it says the max supported refresh rate is 60Hz (doesn't mention the ACTUAL refresh rate..!)..

OK so what..? -- well I've posted before saying my TV out sends a colour signal to my TV no problem but when I record it to VCR it is always black and white..
(using composite leads (tried a few), several VCR's - double checked the leads and sockets by recording direct to VCR from a camcorder and everything is fine --- all the settings seem ok for UK) -- I just wondered if for some reason my card was outputting at 47Hz, 56Hz or 60Hz instead of the required 50Hz.

Is there anyway to set a Custom Refresh rate (ie type in the required figure?) - I've tried Rage 3D Tweak but no option for 50Hz..

Does anyone else's AIW have an option for 50Hz...???

Please Help....

Thanks

Hi,

If you had the refresh rate set to anything other than 50hz, the picture would not only be black and white, but probably rolling too on the recorded VHS.

Take another look here:

You need to set the TV out to 640x480, not 800x600. There is a remote possibility it is this.

I have never looked at the output of my ATI card on a scope, but if the picture size is set too big, as it would be in 800x600 it might cause some interference with the colour burst. The colour burst is a part in the composite signal which is used as a reference for the chroma part of the signal, I won't go into detail. If this is low level or corrupted in some way it could cause the problem you have.

Incidentally, out of the 2 PC’s I have with an ATI card fitted only one will record correctly on a VHS, the other is B/W, well cycling colour, this problem moves with the card if fitted to the other PC. As I say I have never checked it with a scope but I bet it is to do with the CSC not being correct, at 4.43Mhz.

Try the resize to 640x480 first though.

Err, yes I was going to say that too, I had to put my reply in both places to make sure no one went to the effort of saying the same thing just said in another forum. Ta. GG
