Card could be faulty but to be honest I'm not sure, what do you guys make of this:

I can play a game, 2 hours straight with no problems what so ever, no glitches etc. As soon as i exit the game i have all these sparkley colours all over my desktop + on web pages etc.

Even on here right now on the light blue and the ocuk logo i've got some weird sparklies o_O Going to try driver cleanering the drivers tomorrow and reinstalling but sound like a fault?
 
Oh ........

Hopefully this doesn't sound too stupid but i've just disabled a setting called "alternate DVI operational mode" in CCC and it's gone? Can anyone explain this setting for me?

It does mention about high resolution displays when i highlight the setting, although it does say enable it to FIX corruption lol, i'm running 2560x1440.
 
The "Alternate DVI operational mode” is, depending on your monitor, activated or deactivated. You should only use this option if there is a problem with the displayed image.

copied from another page

not sure if i can link it
 
Cheers Kiel, it was on by default so I've turned it off for the time being. Does it sound like that could be the problem though rather than a fault with the card?

The fact it was fine in game for 2-3 hours and I only seen a problem on the desktop was very odd.
 
When you say
"Hopefully this doesn't sound too stupid but i've just disabled a setting called "alternate DVI operational mode" in CCC and it's gone?" does that mean the setting is gone/greyed out or the artifacting/sparkley colours have gone?
 
The sparkly\funny colours went as soon as I turned it off. The last ATI card I had was a 5870 and the drivers were completely different then so I've never seen these settings before.
 
5870 had that setting too. There is nothing wrong with your graphics card. As you have found the bad setting now and as you and others have found that can be a very important setting depending on the monitor you own and can fix screen artifacts that may occur if enabled or disabled. If it never does it again after you changed that setting it means all is well and I bet if you screenshot the screen when showing the artifacts they would not be there once you viewed the screenshot on a clear screen before gaming. This will prove the monitor is at fault not the graphics card.

that wouldn't prove anything, if the graphics card or monitor were at fault neither would show in a screenshot.

Maybe I misunderstand how this works but why wouldn't it show in a screenshot if the graphics card were at fault?

Isn't a screenshot just an image of what the graphics card is outputting, faults and all?
 
If the fault is on the gpu or vram it would show up on a screenshot aslong as the fault on the graphics card is not on the output stage eg hdmi, dvi etc.
 
I am having this issue when my PC goes to sleep and I wake it up. Glitter coloured blocks?

I've found that changing the resolution and then letting it go back to default removes them. I guess because it rebuilds the screen?

Edit. I too am running DVI. Where is this setting you speak of please?

Catalyst control center > My Digital Flat-Panel > Properties > two settings at the bottom (also change CCC to advanced view, not sure if it's different in basic)

EDIT: purgatory + surveyor - I was under the impression that a print screen will only capture what windows is intending to display, not actually take any display faults the graphics card or monitor are showing. Hence why people with graphics card and/or monitor faults generally take photos of their screens rather than print screening the problem?

Windows can only display the image being generated by the graphics card.

I don't see how Windows can "intend to display" something different.
