Monitor won't wake up when coming back from sleep (Windows 7)

Anonymous

I recently upgraded my Dell Dimension desktop to Windows 7. In order to do so, I had to install a new grapchis card (NVIDIA GeForce).

I set the PC to sleep after a period of time. When I go to move the mouse and wake the computer back up, the PC itself seems to respond, but the monitor never comes back from sleep. I have no choice but to reboot to get the monitor back.

Any suggestions?

A Universal fix would be ideal but - ASUS appears in 14 out of the 16 pages in this thread!!! Not saying everybody having this problem has an ASUS motherboard but if they do, and it seems a high percentage of people do, then they need todisable the PLL Overvoltage in their BIOS!!

IT ACTUALLY WORKS! Not just a workaround, my Computer AND Monitor now both wake from sleep by simply moving the mouse!

Also, obviously only people who have this problem are going to come here. If this is a wide-spread Windows 7 problem, then what about all the complaints large companies like HP Compaq and DELL etc would receive when their customers have the same problem? If they received many complaints and being that  they have a much bigger voice than us they would simply demand Microsoft fix it. I also have a TOSHIBA laptop running windows 7 and it sleeps and wakes just fine.

So if anybody who has friends or family who own a 2011 Dell, Acer or HP etc that came out brand new, factory loaded with Windows 7  please ask them if they have this issue or not. (These companies may have had this problem initially but I would imagine it would be fixed by now??!!)

A lot of people who have this problem also seem to have a separate Video Card (I have a Sapphire Radeon HD 6870 which of course the monitor is connected to) Do any people who are using integrated graphics also have this problem such as people with an H67 mobo?

I am curious as to what percentage of Windows 7 users have this problem. We may find we are in the 1% bracket and 99% of Windows 7 users don't have this problem. It may just be incompatibility of Windows 7  with either our hardware or settings.

In my case disabling PLL Overvoltage works! :-)

    OK, I have it connected - went to sleep and woke up - both monitors - just fine. I may have to wait till I reboot to get a complete picture.

    The key might be the WDDM v1.1 issue. make sure the video board firmware is up to date and that the driver states someplace "WDDM v1.1". If it is only v1.0 then this problem may be an exhibit of the incompatibility.

    FYI

    I have W7 x64 and a 8600GTS video with an nVidia 8.15.11.8593 driver that specifies in the device manager that it is (Microsoft Corporation WDDM v1.1).

    Everything works perfectly relative to the off topic issue.

    I also read a thread in another forum that suggested that ATI did not support WDDM v1.1 on some of its product.

    I'm not sure how to rationalize this being an M$ issue when so many, including mine, run perfectly. HOWEVER, I do not have two monitors attached, but I think I can try that. I always wanted to anyway.

    I am also having this issue.

    My PC never goes to sleep though.  I have the power settings configured to turn off the monitor.  When returning back to my PC, the monitor never wakes unless I power cycle the monitor (not the computer).

    It's very annoying but I cannot for the life of me figure how to fix this.

    My system:  Win 7 x64, Nvidia GTX 285 Black connected with HDMI.

    I would love to see a solution to this problem!

    ALRIGHT now we are getting someplace.

    """Is everyone missing the point that my computer does not go to sleep?"""

    MAYBE everyone is missing this point because the described problem of this thread refers to the COMPUTER going to sleep NOT the MONITOR only.

    Try starting a new thread............the answer is not "RiDICULOUS" based on the above subject,

    AND just FYI - monitors go to sleep because they stop getting a signal - the signal comes from the graphics card.

    so u have to ask why is ONE monitor, driven from the same card, is waking and one not.

    Ya, maybe it is an M$ issue.
