Video Card Issue

All-

I bought a Radeon HD 6750 yesterday as a slight upgrade and installed it into my computer (Athlon dual core processor at 2.3ghz, 4GB RAM, 500W power supply, Windows 7, old video card was an Nvidia 9600GT). Installation was a snap, installed drivers off the disc no problem, went to AMD’s website and got the latest drivers no problem, played a brief round of games with graphics enhanced over what they were, no issues.

My issue is this: I generally like to put my computer in sleep mode when I’m not using it so its not totally rebooting from scratch. Every time I have done this, I get the login screen just fine, but once it arrives to my desktop its all screwy. Icons and my background are terribly pixellated, as if the card is having trouble resolving it. When I reboot, the boot lettering is in a really low resolution and all big and stuff…but then I get to the login screen and the resolution has been resurrected to its previous setting. Then I get to my desktop just fine and everything is fine.

So why every single time I go to “wake up” my computer from sleep mode is it doing this erratic pixellation crap once I get to my desktop background? Its really weird. The new card seems to be performing well in every other way but I have to restart the thing every time to get it where its supposed to be.

Any ideas?

Well, I’ll give this the honorary bump it doesn’t deserve, hoping someone like Kinthalis will chime in with a resolution (snerk).

Did you remove the Nvidia drivers?

He said the boot lettering was off, the drivers shouldn’t affect the display when you’re displaying the initial boot info (i.e. before it gets to Windows).

Sounds like the card is having an issue restoring the correct resolution when waking up do a “handshake” error with your display device.

Are you running a PC monitor or using a TV as a monitor?

And is this an intermittent issue or is it happening every time you wake the PC from sleep?

Also, what type of connection to the display device are you using? HDMI, DVI? Display port?

Yes. The manual for the card instructed me to do so and I did that before installing the new drivers for the new card.

It appears to occur every time I put the computer in sleep mode…even restarting from there causes it to happen. If I do a full shut down, then reboot, its fine. Its a really strange issue. I am using a modern, HD-capable monitor. And the connection is DVI. The card has two HDMI outs but they are unused.

The issue is most common with TV’s.

You said you have the latest drivers from AMD, did you also look for drivers for your particular monitor?

Did you check your monitor settings. Sometimes there is DDC option, which you want to enable (it tells the GPU about the monitor capabilities).

I did check for my monitor drivers last night. I can’t remember the model number as I am at work right now…its an LG Flatron (something something). I was having a hard time finding drivers for my particular monitor model…I will check out that DDC thing when I get home from work…thanks!
