Dual Monitor - One Doesn't Wake Up From Sleep
Dual Monitor - One Doesn't Wake Up From Sleep
(OP)
Ok - on my last nerve here.
HP Compaq Elite 8000 SFF Desktop - windows 7 Pro
Added a second monitor to the built-in Intel Graphics card using one VGA connection and one Display Port to VGA adapter
Monitors set to sleep after 15 minutes
2nd Monitor (without the START button) will go to sleep and NOT wake up. Have to reboot the PC
Updated the BIOS, set the BIOS setting and updated the video driver per this document Link
No change!!!!
I do see other people complaining about this specific computer and dual monitors but no real solutions.
So, I installed an Nvidia Quadro NVS 290 card thinking it was the video card. Same thing still happening!!!!
So, it's NOT the video card.
Even stranger - Two of the same model computers exhibit this behavior and one does not.
Thinking of using the "HP Replicated BIOS setup utility" to compare BIOS settings across computers. Any other ideas?

If you want to make sure you purchase a reliable replacement, order the HP brand, which often comes labeled as "BizLink". I have yet to see one fail.

And the one computer that isn't having the problem is still using the DisplayPort to VGA adapter with no sleep problems.

Also wouldn't hurt to reset the BIOS settings to their default settings.

This gets weirder all the time. One of the computers that was having the problem has stopped with the new video card!! The other PC that got the same new video card is still having the issue.
The monitors are all over the place - Dell, Viewsonic - some are pawn shop specials, not kidding. But it shouldn't be rocket science to have a working monitor wake up. I did reverse the two monitors today - changing the VGA plug they were connected to to see if the problem follows the monitor or not.
By the way - it is always the monitor that does NOT have the START button on it that won't wake up. If I don't fix this soon, I may end up in a river with the fishes.

- Go to "Device Manager --> Display Adapters"
- Disable all video adapters
- Enable all video adapters
Courtesy: http://answers.microsoft.com/en-us/windows/forum/w...Apparently that worked for quite a few peeps, so why not? Also saw some threads suggesting disabling Hybrid Sleep in power options, and another that said to turn off sleep for displays, reboot, then turn it back on. Last but not least, might be worth running Windows Update on it.
Good luck!

I'm getting to the point where I may use a BLANK screen saver with NO sleep to simulate proper sleeping of the monitor. Kind of "dishonest" but................
