Weird video graphics problem.

[MONOLITH]

Radeon X800 Pro.

After installing the latest catalyst 6.9 driver the other day, everything has been fine until today.

I did a re-start (for an unrelated reason), and after restarting, I had no video signal to my monitor through my usual DVI cable. I hooked it up AGP, and there was a signal. So it seems my DVI output died.

Then I ran a DXDIAG, and when you do that test where you see the spinning cube with the green X on it; My cube is spinning hyperfast. I can see it, know what it is, but it's spinning so fast it's all a green and grey blur.

DXdiag says 'no problem found'.

So, my DVI has no output, and my dxdiag cube has gone hyper.

I uninstalled the driver, and reinstalled the previous 6.8 to see if it was the driver. No change.

What do you think, has my X800 fried?

I should add that playing games, everything looks fine and normal. So that makes me think the card is okay. Except that I can't seem to get a DVI output, and that spinning cube issue.

In the old CRT days, a hyper-fast anything could have been a problem with a video card not computing properly for any monitor scan rate higher than 60 Hz.  The problem would surface for folks who had jumped ahead of everyone else, and built a super-fast computer processor and video card, without having the benefit of the game company providing a patch to keep up.  The only solution was to force the monitor to run at 60 Hz.

It will be interesting to see what this is, if you can find out.

Hmm, there is a ramdac on that card to translate from the digital frame buffer to the analog out for VGA.  There is a different chip to send the output from the frame buffer to the DVI output and provide the proper signals.  My guess is that you may have burned out or damaged that DVI chip somehow.  I don't know why that would have an effect on your spinning cube other than it may have also fried one of the pipelines or some facility that is only getting used on that test (the tests are meant to test "everything").

But if the card's working okay for everything else I wouldn't worry about it unless you really need the DVI out.

Have you tried running GRAW PC on it?  That game taxes systems pretty badly.

This thread is two months old to say the least and I am sure if mono was still having the problem he would not have created the "Why I prefer consoles" thread. :tongue:
