I've got an ATI Radeon Sapphire X700 Pro with an S-Video Out, running XP. I had this going into my tv, and it worked fine until about a week ago when for some reason it suddenly seemed to be all garbled. Playing video gives constant pulsing glitchy flashes. Otherwise, the image is still - no rolling. And the background just looks really garbled, as if it's sort of randomly tiled, and I can see the mouse cursor and windows, whereas I used to just see the desktop background.

Colors are fine, and the mouse cursor looks perfect, and moves across the screen with perfect accuracy, but everything behind it is weird and garbled.

I just can't figure out what this is, and I haven't found anyone else who has seen this problem. I did find this in a forum for a utility called Powerstrip:

Garbled Screen: Tile-based Rendering enabled

If you are confronted with a screen where everything is garbled but the mouse cursor looks fine then try disabling tiling. This is done in a hidden option In PowerStrip. Go toDisplay Profiles -> Advanced Timing Options -> Custom Resolutions and double click the "New Resolution" title bar, it should then pop up a window that will allow you to disable tiling.
I have recently read some posts that claim that this has been fixed in ATi Catalyst Driver 3.7 although I have still to verify it.

I do have an up-to-date version of Catalyst Control Center, and this Powerstrip utility also did not have Radeon listed under supported cards. Does "tile-based rendering" have something to do with it, and is there any way I can adjust this?

Otherwise, I just hope SOMEBODY knows what this issue is and can help me out...

Thank you!

Cataylist 7.3 was released yesterday. I was working on a new ATI Sticky and did all the research but i'm not on that computer now. But I think the X700 was supported under 7.3. you posted 3.7 but that must have been backwards because the only other version were 6.x.

You should try the update first and then give us the results.

I recognize 7.3 as the version I installed yesterday. Just in case, I re-installed the 7.3 display driver. When I check the Catalyst Control Center "About" properties, it says "Version 2007.0320.2241.38712".

So I don't see a "7.3" in there, but hopefully the date "2007.0320" in there reflects that this is the newest version.

Anyway, the problem persists. Though I did notice for the first time here that on startup, the Windows XP logo screen, with the little scrolling blue bar? That looks perfectly fine. No distortion whatsoever. As soon as it hits the blue Welcome screen though, then it's all screwy.

I'm at a loss. I've tried so many options in the Control Center and in the Windows display properties, that I'm just out of ideas.


A couple of screenshots:

This distortion is always the same, the same tears in the same places, and it doesn't move - ie, there's no rolling lines, it's all perfectly still.
And that mouse cursor refuses to ever be distorted either, it's always perfect, no matter what's underneath.

with all the driver software changes, is the allocated resolution for monitor #2 (the tv) still set at the compatible max resolution of the tv? my old example was 1024x768 but nowadays I am not sure. You are doing things with the old technology using svideo but no one expects someone to go out and by a video card just for tv output or HDTV output. I was sort of amazed when I found out that my Nvidia 7600GT came with HDTV support and a set of component video cables to plug right into my TV. I am almost curious to see what my PC will look like on a 32" Magnavox LCD though I'm guessing the 1300x768 resolution that most of the 32' LCD TV's have may make things look a little L A R G E, lol
