Steam preventing win10 from putting monitors into sleep mode

[modQuad]

CPU: AMD Ryzen 5 2600X
GPU: NVIDIA GeForce GTX 1650
RAM: 16 GB Crucial Technology 1333.3 MHz (DDR4-2666 / PC4-21300)
PSU: THERMALTAKE SMART 600W 80+ ATX PSU

Monitors: 2 Lenovo LI2264d - HDMI (main) & VGA connections.
OS: OS Name Microsoft Windows 10 Pro
Version10.0.19042 Build 19042

No overclocking of any components.

I have narrowed this issue down to Steam. if I exit steam completely my monitor will go to sleep, but if I leave steam running in background it prevents it from ever turning off the monitor.
PC Sleep works as intended - monitors will not enter power-save mode with Steam client running.

I've tried reinstalling Steam, removing all temp data from %APPDATA% - also tried the standard and beta clients. Issue persists.

I like to have monitor go into power save mode, any ideas?

Steam only does this if its left as the focused window, X out Steam and it will be auto-minimized to the Notification bar, at which your Sleep Timers should work normally afterwards.

DO NOT use PC Sleep Modes, as this will turn off everything.

Just select Power Options = High Performance, then edit the profile for.
Monitor off timer = # minutes
HDD Sleep Timer = 0 minutes

I'm afraid closing to tray doesn't work for me. I have Steam launch to my Library as I've also been told having the Store open can cause this issue, as it's playing background video/audio streams.
I'm using the Ryzen Power Plan. Sleep works fine. Monitors won't enter power save mode.
Only fix is to close Steam entirely as this issue is isolated only to the Steam client. Standard & Beta.

Its not any sort of a Steam issue. I've used it for many years and even today with everything up to date it never does this. Only if Steam Client is my focused window. As I often leave Steam on all day long for various Downloading purposes and my 3x Monitors all go into power saving mode after the time I set within my Windows Power Profile. So I know for fact Steam doesn't hinder this. Yes it can of course be possible to have any window, app, or browser thats actively playing a video to maybe prevent this, but otherwise it shouldn't if it's minimized, as its no longer in focus and thats the only thing that prevents sleep of any kind in that regard. Purhaps your mouse sensor is dirty and is preventing any screen saver or monitor power saving to occur. Change setting in Device Manager for Mouse that prevents Mouse to waking the system. This way there is no way moving the mouse alone will keep the system awake or prevent its various power saving timers to kick in.

Weird thing is that this also been happened to me too. My monitor always turns off after a certain amount of time I set it to but now it doesnt. Not a big deal but dont want my monitor to have any burn ins

When you have the system idle and you going to walk away or go to sleep and allow things such as Steam or whatever to run in background, download, etc. Press WINKEY+L and then see if your Monitors go into power saving mode normally again. Could be some sort of bug with whatever OS version you are on, or Drivers, but Steam Client surely is not the actual issue at hand.

Did the suggestion above and it didnt work for me. I know its not steam for me but not sure why my monitor isnt going to power saving mode. Maybe because one of my devices connected to my PC is keeping it from turning off not sure.

As I said in my original post, it is a Steam issue. I've isolated the issue to Steam. I've done multiple queries on wakelocks using powercfg.exe - it's not the mouse or anything else.
No other app on my PC prevents the monitors from sleeping. The issue only happens when the Steam client is open. It can be minimized to the tray, and I've set it to auto-open to Library instead of Store.

Your replies are dismissive and unhelpful - denying the problem that's right in front of me. The manner in which Steam interacts with the Windows Power Profile is problematic. That's the bottom line. It's the Steam client.

Now - can we stop debating that fact and talk about actual solutions?

Not sure if its steam but if a exit my steam completely should it resolve it?

I don't know why Microsoft makes this so stupidly difficult but....If you go into Contol Panel, then Network and Sharing Center, then "Change adapter settings" on the left side, then right-click on your Network type: WIFI, Ethernet whatever--then Properties, then the Configure tab.

Under the Power Management tab, what is checked, if anything? You might try unchecking anything and reboot to see if the machine now sleeps peacefully. If not, just go back and revert.

I had to do this myself, something was always waking my PC up. This is just one course of action, there are prob. others. But it's something to try at least.

I also have this problem. Even if Steam is just in the tray, my PC will not go to sleep. The monitor will turn off then turn right back on. No requests are in powercfg. Even if I lock the PC, this happens. If I exit steam so the process is dead, then the PC sleeps fine, so it's not a network setting.

Weird for me its not steam tho. Tried exiting Steam out and set my display to turn off after 1 min but still doesnt work. Did the recommended tip above to turn something off in network and still acts the same

Huge bug here.

Needs a fix.

I set my sceens (2) to sleep after 5 mins but so long as the steam client was running (or in the tray) the screens would just blank for a few seconds and resume. However I uninstalled the MS wireless display adapter from the windows store and now the monitors sleep properly. I wasn't using the adapter any way so it's not an issue. https://www.microsoft.com/store/productId/9WZDNCRFJBB1

Not sure if its a steam issue either, I have steam set to open to library and when i close it it minimises to tray icon. My machine sleeps and wakes as it should. Thinking its maybe a steam setting that does it rather than a steam bug, maybe one of background options does it?

I do not use the steam overlay, cleared the check for vulkan shaders in the background and i do not have steam start in big picture by default if that helps at all.

[Bad 💀 Motha]

Steam Overlay is not active outside of Games; so that setting couldn't be any part of this issue.

Now if you use Steam Big Picture Mode in any ways, YES this will force the Displays to stay on at all times. Vulkan Shaders won't do it either, as this is nothing more then a Steam Download as a small cache files.

What I've usually found is this happening to users with Wired Mouse. The high sensivity or dpi setting means that a tiny vibration is enough to move your mouse sensor just enough to wake the system from Sleep or from Display Power Saver (aka the Display power off timer in Windows OS).

When I want a system to sleep and I'm walking away from it or going to bed, you have two options to avoid a wired mouse causing a PC wake up of any kind > Flip the mouse over on its back so the sensor can't interact with a surface. To help ensure this, also look at your mouse and blow out the sensor hole from time to time to help ensure there isn't dust. The sensor could easily be tripped and move your cursor just by a tiny hair or piece of dust somewhere inside the mouse sensor hole. Another option is simply go into Device Manager and change the Power Management for your Mouse Device and untick "Allow this device to wake the system". Do this also for Game Controllers/Sticks/Wheels. However never do this for your Keyboard.
