    Turning off a monitor acts like disconnecting it


    I have two monitors, both connected on DP.


    When I turn off my secondary monitor, nothing happens. That's good.

    When I turn off my primary monitor, something happens: Windows acts as though it was disconnected, and moves all windows and desktop icons over to the much smaller secondary monitor, messing up window sizes and icon placement.


    Turning off a monitor should not act like it's being disconnected. This happened with my previous primary monitor on DP as well. This does NOT happen when I connect either primary monitor my old one, or the current one on HDMI.


    The solution is NOT to connect my primary monitor on HDMI, because that will disable high fps and HDR.


    I'm running the latest Nvidia "game ready" GPU drivers and an up-to-date Windows 10 20H2. My system files are good, says SFC. No viruses or malware either. Just so I don't get that canned response again.


    So the question, to be extra super clear: How do I make Windows, when turning off a primary monitor connected to DP,NOT act as if it was disconnected, but leave everything just as it is?


    Please advice.

    :)

  2. Disconnected/Connected Sound when turn ON/oFF monitor

    Not solved yet. Dont know what happened to my windows 10 Insider. It still have sound like disconnected when I turn off the monitor and connected sound when I turn the monitor on. When I turn off the monitor, I used Teamviewer to view what happened and I saw seem the monitor is disconnected to my 1080Ti.

    Primary monitor blacks out after disconnecting from external

    Hi Oscar,



    Thank you for writing to Microsoft Community forums.



    • Are you aware of any changes that happened on the computer prior to this issue?


    This issue could be due to the display setting corruption that only affected the primary display when disconnected from the secondary.



    I suggest you to try the steps listed below and check if it works for you:

    • Press ‘Win + R’ keys on the keyboard together to open the Run dialog box and type the following into the Run box:
      appwiz.cpl
    • Uninstall Intel HD Graphics Drivers and exit
      Programs and Features.
    • Right click the Windows icon on the taskbar and choose
      Device Manager
      .
    • Expand Display Adapters and right click on
      Intel HD Graphics Display Driver.
    • Click on Uninstall and check the box
      Delete the driver software for this device.

    • With the external monitor connected, reboot the machine.
    • Once the machine boots into the desktop, disconnect the external monitor and check if the issue persists.


    Hope it helps.

    Regards,

    Overclocking / Undervolting guide for Vega 56 or 64?

    Here's a quick laundry list:

    List of software to use for overclocking and testing
    Examples:
    Wattman (and how to find and use it, like an overview, including profiles)
    Unigine Valley or Heaven (use this for quick testing while changing settings in Wattman and checking for stability / artifacts) ...just suggesting this
    How to monitor cores / mem speeds and temps during testing (I've seen screen overlays, and others using GPUz)

    Step-by step overclocking in Wattman
    Fan speeds
    Power limit
    Temp limit
    Voltages
    Core speeds
    Memory speeds
