Single Display split image

I have the most bizarre issue with my R6950 Twin Frozr III IGD5 Power Edition. I've formatted a few times and installed the drivers a few times and I still have this issue. I'm trying to work out if I have a dud or not. Every so often the screen splits so that a quarter of the right side of the screen ends up on the left side of the screen. Anyone have *any* experience with anything like this or do I have a dud?

Here's what it looks like, note the start button a third from the left side.

Thanks in advance for your input.

That's what happens when the card's vram is running too fast (on my 6850 I could bump up the memory clock 25MHz past its stable limit, and in 20 seconds like clockwork the display would get offset like you describe). So if it's happening out of the box with no modifications, yeah it's a dud.

Exactly what happened with my old 6950 as well.

Thanks guys, well I'm pretty sure it's still under warranty, it was only purchased last summer. Hopefully they'll fix it (or replace it)... I recently had issues with my MSI 640GX gaming laptop, MSI isn't really making me so happy lately. They did fix the laptop, but I had to ship it back to them 3 times as they broke something else when they fixed it, then couldn't reproduce the issue I was having with it, then I had to prove that what I said was happening, was actually happening. If they give me *any* issues on fixing this card I'm done with MSI.

If that is happening inside the framebuffer, the above is correct. This can also happen if the monitor somehow jacks up the Horizontal blanking space. I've pushed my monitor too far and had about 12 full tears in random places throughout the screen (both vertical and horizontal). That was a pain in the ass to navigate my way back to defaults.

Most likely the above guys are correct, just telling you something else that is possible albeit unlikely.

There is also the small chance the EDID information for your monitor is being read incorrectly. I had exactly the same take place on a monitor I have with nvidia's drivers not correctly identifying the monitor.

It is possible that it could be something like that as well.
