Monitor not waking from sleep

[Lordofdeath123]

Hi everyone.

My problem is that whenever I use the sleep function on my Windows 7 PC, the PC wakes up fine, but the monitor does not. I have to unplug the HDMI cable and plug it back in. Then it works. Also, the folders etc are all resized afterwards, which is why I am thinking that its a GPU driver issue.


I know this issue has been posed numerous times... I have read dozens of forum threads in Tom's Hardware, Overcklockers, Windows forum (though they are generally rubbish) and many others. I also read blogs.

Unfortunately, I was not able to fix this. So here it is.

I have built this PC 4 years ago (Spec below). Sleep was never a problem. About half a year ago, I installed an SSD on it and installed a fresh version of Windows 7 (I had Windows 7 with the same installation before as well). Then, I tweaked a few things, like moved the download folder, cache folders etc to other hard drives.

I also disabled pagefile.sys and hybernate.sys (or whatever it is called). I then noticed that sleep the monitor was not waking from sleep, though the PC was, but had other stuff to do. Later, I re enabled them both, but this did not fix the issue.

I made a clean install of my graphics driver. It did solve it, but only until I restarted the PC again.

My Specs are as follows:

Intel i5 3570 - CPU
Nvidea GTX 660 - GPU
Asrock H77 Pro4 - M - Mobo
Sandisk SSD Plus 120 GB
12GB of DDR3 Ram (forgot which, I think Corsair)
WIndows 7 fairly updated OS (up to Feb 2017, minus the spyware-updates).
Samsung S23B300 monitor.

Anyone got any ideas?
Cheers.

I would say your problem lies above. Examine both again make sure they are being used. I thought sleep used hybernate.sys but could be wrong.
Personally and at work never use Sleep. Its evil and causes countless problems often causing problems with Windows having to be reinstalled.

hybernate.sys is only used for hibernation.. at least in theory. As I said, turning it on, restarting and testing did not show any signs of improvement.

Upgrade to 10 then boot up it a few seconds never have to use sleep again

How is the monitor connected to the GPU? Could try a different connection maybe? Can you also test with the onboard Intel IGP?

No reason to disable pagefile even with an SSD, SSDs can handle it just fine.

Sorry all for the delayed replay.

@ imginy I'd rather use Linux

@Orcvader I have it connected to the GPU with an HDMI cable. But trying with the on-board GPU is a great idea. I will do so today later (this is also my work PC) and post when I have done it.

Thanks all.

Thanks Orcvade,

I changed the HDMI cable to the analogue cable, from my video card (i.e. both times from the GTX 660) and wow... now it works...

I don't really understand. If something is wrong with the HDMI cable, then why does it normally work? and if only the initial starter of the cable is broken (I don't know, I think a cable has many pins and one of them is I believe also responsible to sending the `wake up' signal), why does it work when I boot up the PC, or when I disconnect it??

All very strange.

But thanks a bunch for the replay, I have something to go on now. I will try a new HDMI cable for starters. Cheers.

Might be worth trying DVI as well if possible, maybe the GPU isn't properly waking up the HDMI connection or something. I would rather use DVI over HDMI and VGA.
