LCDHost preventing main display power off

[GranoblasticMan]

Thanks, I didn't know this existed. Running 'powercfg -requests' shows None for everything, unfortunately, but something is still keeping my displays on.

Bummer. I was almost certain that would fix it.

Thank you. I have tried all those options and my settings are correct. If LCDhost isn't running my displays turn off fine, and if LCDhost is running they always stay on.

Still having the same exact problem here.  Have tried every suggestion- run energy reports, tried powercfg, nothing works.

If I run LCDHost with ANY layout, screensaver never comes on.  If I close it, the screensaver works fine.

i have the same problem, is there a way to fix this?

Due to other circumstances, I was forced to do a fresh install of Windows 7. The screensaver worked for like, the first week or so... then suddenly it stopped activating. Every once in a blue moon while the screensaver will work, but 99.9% of the time it will NOT work.

Same results with the powercfg -requests. Everything says "none".

I'm still having the same issue.

If I lock my computer (so I'm at the windows password prompt), the screen will turn off, while LCDhost continues to run. This is my workaround so far instead of shutting down LCDhost, but is still manual as the computer doesn't lock itself even though the setting for that is on.

has someone found a workaround for this ?
I think that is something related to shared memory, as if i disable sharedmemory export in aida64, even if lcdhost is opened, the screensaver runs.

Hi,

As per the query you are trying to set the monitors to sleep after 10 min of inactivity and after 10 min you see all the application were on the main/primary monitor.
 
Please provide us the below information.
1. What is the make and model of your Computer?
2. Which windows 10 build are you using?
3. Do you get any specific error code?
 
The issue might be occurring due to corrupted display drivers.

Lets update the display drivers :

1. Press Windows key + R, to open the run command.2. Type "devmgmt.msc" and press enter to open device manager.

3. Expand "display adapter".

4. Right-click on the driver and click on Update Driver Software.

5. Your computer should find and automatically install the updated driver. 
6. After the installation is complete, Restart your computer.     

Keep us informed with the status of the issue.

I've been having this problem since I switched to win10.
Current win10 build is 1809, but also had it on 1803 and previous builds.

Display adapter driver is updated (Nvidia Geforce 1070GTX).
