Ever since I hooked up my second monitor my Primary monitor will no longer turn off during power save / idle (not sleep just idling). my second monitor will turn off and go black but my primary monitor will go black for a second but then display a black screen with the backlight still on. before I had my second monitor it would turn off during power save just fine, and I didn't change any of the cables or ports when I got my second monitor. anyone know a way to fix this so my primary will sleep, or maybe even switch the problem to my second monitor.

also forgot to say that when i shut my pc off, or put my pc to sleep, the monitor will turn off so its only during idle power save.

PC specs:

Mother board: Asrock b450m pro

CPU: Ryzen 5 2600

GPU: Asus tuf GTX 1650 super

RAM: 16gb 3200mhz

Monitors:

Primary: GIGABYTE 24F 165hz (hooked up with display)

Secondary: Acer K202HQL (hooked up with a dvi to hdmi)

    Hi and thanks for reaching out. My name is Bernard a Windows fan like you. I'll be happy to help you out today.

    This problem actually occurs when there is a problem with your power options, kindly follow the steps below and I hope this helps.

    Method 1. Restore default power options

    -Press the Windows key + R then type:

    powercfg -restoredefaultschemes

    -Restart PC and check.

    Method 2. Run power Troubleshooter

    • Press the Windows key + R then type:

    msdt.exe /id PowerDiagnostic

    • Click OK then follow the prompt to run the power troubleshooter

    -Restart the device after

    Method 3.

    Open Control Panel> Click Hardware and Sound > Click Power Options> then click Choose what the power buttons do > Click Change settings that are currently unavailable> Check Sleep (or uncheck then check it again)

    Click Save Changes then restart.

    Method 4. Do clean boot:

    A “clean boot” starts Windows with a minimal set of drivers and startup programs so that you can determine whether a background program is interfering with your game or program.

    • In the search box on the taskbar, type MSConfig and select System Configuration from the results.
    • On the Services tab of System Configuration, select Hide all Microsoft services, and then select Disable all.
    • On the Startup tab of System Configuration, select Open Task Manager.
    • Under Startup in Task Manager, for each startup item, select the item and then select Disable.
    • Close Task Manager.
    • On the Startup tab of System Configuration, select OK. When you restart the computer, it's in a clean boot environment.
