The graphics card or the monitor...

Hey guys,
Sorry, yet another post about my monitor. This time, I've just noticed some strange shimmering pixels in parts of the screen. I've posted a pic to let you see what I'm talking about.

I'm thinking its the graphics card because when I minimise the window where these artifacts are, they disappear and the picture is fine. I've also got the same effect on the occasional website.

Can anyone confirm this is the case? Or could this still be the monitor?

Cheers,
Andrew

Try the ATI tool, there is an artifact scanner on it, it will tell you if its the gfx card

Press Print Screen on the keyboard (when those blue bits appear), and then paste it into Paint or Photoshop or something.

If they're in the screenshot, it's the graphics card (or something hardware-related, at least). If they're not, it's the monitor.

To be honest though, I'd say it's the graphics card anyway.

damn... pasted that into photoshop and the artifacts weren't there

boy, i've never had this much trouble from a new screen (noticed that when I boot up, the res is squashed and slightly offside - i always have to go back into the control center and force the refresh rate back again to higher than it is - then its fine :-)

)

The POST screens often seem to be moved to the left (to the extent they're cut off)...I don't know why.

Hmm, but when its finished booting and loaded onto the desktop, its about an inch to the left, dropped half an inch, and also squashed...

also, managed to find that tray tools install, and ran artifact scanner for about 15/20 mins and no artificats were found... so on top of photoshop not showing up the artifacts when i took a print screen, this is looking like a dodgy monitor...

Make sure your connection to the monitor and graphics card is solid as I have had this happen to me before when the cable was loose on the monitor.

whats your setup?

I get the same on a shuttle ive got, its not the g card as i have had 3 diff ones in and certainly not monitor.

Is the monitor connected with DVI? Is it possible it has something to do with that?

The only LCDs I've used have been VGA, but I'd imagine a DVI connection (being digital) could result in corruption of some kind if it's either not connected up properly, or if there's some kind of problem with the DVI output on the graphics card.

this could only be the cause if the whole of windows was affected - but from OP doesnt it say that when a window is reduced the problem disappears?

Corrects myself if the window is 3d then I might be correct and vga card is dodgy - if its a standard 2d or MS Windows window then its more likely a cable or TFT problem
