New HD 7750 puts my monitor to sleep ... ?

Last week I got the "Sapphire ATI Radeon HD7750 Ultimate 1GB PCI-Express Video Card fanless" and it's great but I've noticed a few quirks...

* If I turn my computer on, then turn my monitor on after it's already past the BIOS, the monitor will stay in power saving mode and not display a picture. When I restart and it's on, the windows are shrunk, like it was just on a smaller resolution.

* Sometimes over night if my PC is on and the monitor is off, it'll switch the monitor to power saving mode and won't display any picture when I turn the monitor on.

Pressing keys doesn't help, turning the monitor on and off doesn't help (It's a Dell 30" 3008WFP). But unplugging the DVI cable and plugging it back in fixes it. Or restarting my PC fixes it too.

I've tried a new cable, and updating to the newer latest drivers. My older graphics hard had no such problems for years, with the same monitor.

I was wondering if anyone had any thoughts? If it's a faulty card that's one weird fault!

Also if it helps, I'm running Windows 8 64-bit, AMD Athlon II X4 640 CPU, 8gb RAM. Thanks!

Its not really faulty. Actually the Driver you are using got some features which automatically turn the power saving mode of the monitor which is not weird. So, I suggest check your driver settings ( AMD Catalyst ) then it should be fine.

I have a 7750 (HIS iSilence) and mine does NOT do these things. AMDs drivers, even recently, have never really been fantastic. Some of the early versions of CCC when the 7series first came out had numerous power/wake issues that seem to have been resolved. I had several weird HDMI issues with all of the Catalyst versions after 12.8. I might suggest downloading 12.8 (googlamate that), uninstall your entire CCC version, and try 12.8. It just seemed to be the most stable of all the versions I tried, though you do lose some of the new micro-stutter fixes.

Thanks, I checked my settings just now and I couldn't see a great deal to change but I turned off "Alternate DVI operational mode" and in power options for Windows I disabled hybrid sleep. Honestly I don't know if either of those will make any difference but I'll see

If they fail I might try to get 12.8 on there. Although it's not a major issue, so if I'll lose some other fixes that might not be worth it. But I'll see how it goes first.

Thanks!
