Monitor not turning off / pc not entering sleep

[Joburgal]

Has anyone had any issues recently with steam preventing monitors from turning off / pc entering sleep? With steam minimised my monitors will turn off for a few seconds but then immediately turned on again. With steam closed everything works fine in line with windows power settings.

Nothing showing in powercfg/requests.

Tried contacting support but they are useless and pointed me here!

Ok i know i've said this before, but i think i've finally fixed this. I use HDR for gaming on my main monitor. With HDR enabled in the windows settings and steam minimised to taskbar the monitor turns off and then immediately on again. With HDR off everything works fine.

I've tried this 4 or 5 times and every time i get the same behaviour. This would also explain why things have been so intermittent as i periodically toggle HDR on/off for gaming or desktop use. @LDRBT would be interesting to see if this is the same for you!

I really give up... it's stopped working again :-( Starting to think that i might need to do a fresh windows install..

Really frustrating

POWERCFG -REQUESTSOVERRIDE PROCESS steamwebhelper.exe DISPLAY

it has solved this for some.

I have this issue as well, none of the solutions posted in this thread work. I also tried to run the powercfg requests override for "steam.exe" and "SteamService.exe" to no avail.

Powercfg is of no use here simply because it doesn't manage what devices can wake the screen, it only manages what devices can prevent sleep and wake the computer from sleep.

I have went through every option in Steam settings to see if one of them fixes this issue. They didn't. I also tried going into offline mode but it didn't help either.

I'm running the very latest Windows 10 with 980Ti and the latest driver from Nvidia. I don't have any peripherals connected except USB mouse and keyboard.

This is clearly a bug in Steam. Formatting your PC will not fix this issue. We'll just have to wait until Steam developers notice this issue and fix it.

So glad there's another one of us out there! This thing continues to drive me mad. Hopefully there will be a fix soon as is such a pain having to shutdown steam every time i want my pc to behave normally.

So, can you leave the computer by it's self for a minute, or is it only when Steam is currently opened?

My sleep works perfectly fine even with Steam fully open and in the forefront. Maybe try logging out of Friends. I don't have that Window open. do you have any downloads pending? maybe try finishing them if they are.

@CandyGamer83. Yes when steam is closed my display will turn off and then the pc will sleep normally. If steam is open the display will turn off and then immediately on again.

@emoticorpe the problem isn’t that steam is keeping the monitor awake it’s that it’s triggering it to wake up immediately after it turns off. I have never seen this happen before on any other app. Normally it’s a simple case of looking at powercfg to see what’s keeping the pc awake but in this case as the monitor is turning off there’s nothing in powercfg. Over the last two months of troubleshooting I haven’t actually tried logging out of friends.. let me have a go tomorrow :-)

A superstar on another thread found the solution for this. Disable Nvidia HD Audio in the device manager and the sleep issues go away. If you use your monitor for audio this will be challenge but hopefully a fix for most of us :-)

[Joburgal]

Unlike the other fixes... I’m one day in and everything’s still working! :-) Will need to break something else now to give me something to do!

[Carlsberg]

I have Nvidia HD Audio enabled and no issue so i checked why not.

In windows sound control panel there is a sound that plays when the machine sleeps, it does not affect me i think because its not my default sound device which is what windows will use, maybe no need to disable it if this is the case.

That said, glad you found it if indeed that is what it is.

[Slavadir]

I am also having this issue.

Edit: out of sheer frustration I disabled "AMD High Definition Audio Device" and it fixed the issue. Hardly a solution, but that's a workaround I guess...

I think I have is solved with a workaround now. I noticed that there is /lastwake for powercfg command. It was only showing that the PCI-to-PCI Bridge was waking the PC after it goes to sleep. Using HWINFO64, I was able to determine what devices were on the that PCI bus and removed them one by one until the monitor went to sleep. Just disabling the 'Allow this device to wake the computer' checkbox for all of them in Device Manager didn't solve it. I had the 'powercfg -devicequery wake_armed' results completely empty and yet it still woke up about 17 seconds after the monitor went off. It is the Sculpt keyboard from Microsoft that is causing the problem somehow for me when Steam is running only. The Sculpt has a USB dongle. The only way to fix it was to disable the 'Allow the computer to turn off this device to save power' for the Sculpts 'Microsoft Hardware USB Mouse' in device manager.

This does not explain why it is only when Steam is running that the problem presents itself though. What could Steam be doing with the Sculpt mouse? Very strange... especially since I never power on the mouse. I only use the keyboard part of the Sculpt setup. The mouse is powered off in a drawer without a battery in it.

Well... that is how it is behaving today anyway. Hopefully it stays that way. I re-enabled the NVIDIA sound devices and it still seems to be sleeping properly but I don't hear the hardware unplug Microsoft sound so I might have to also keep that disabled if after my next PC reboot that the wakeup happens a few seconds after it goes to sleep again. It is very possible there are 2 wake issues related to Steam on my system.

Fingers crossed.

Built a new PC and had this monitor issue.
Tried many fixes here, all make sense and could work.

FIX (for me) I went to steam settings, interface, clicked startup in library instead of store. Fixed

Notes: I enabled steam startup on my other old gaming PC to see what would happen and to my surprise I had the exact same monitors wont shut off on PC startup with a default install of steam settings. I went to settings clicked startup in library and not in the store and fixed.

Thank you to the person who said they tried it as a possibility and didn't fix it for you. It was the last tid bit of info I could have tried from here and it worked. I'm sure we are all just fine having steam not open in the store. As it happened on 2 of my windows 11 machines that are 4 yrs apart in tech having their own setups I do wonder what the issue is here and why it has not been fixed permanently.

Edit: I tested on a different pc with its own setup and windows 10 and I had no issues with the monitors auto shutting off, on system start with steam auto starting to the store.
