    Monitor Switches on/off 1/second after 25 days Uptime in Windows 10


    Why is it that every 25 days, Windows cycles my monitor on and off once per second when the monitor saver timeout is reached?


    Task manager shows corresponding 100% CPU spikes once per second during the monitor sleep period in which this is happening. When I 'wake' the system, the spikes cease in Taskman. When I leave the system unattended, after ten minutes, the monitor shuts off, then the switches on/off/on/off once per second. The LED on the monitor is staying Green, not Amber like it normally does when it's on standby.


    If I reboot, I'm good for another 25 days.


    What's happening on the 25th day that causes this?

    :)

  2. Monitor Primary monitor layout switches upon second monitor power off

    Hi alts63,

    One of the possible reasons why your primary monitor layout switches is that the rotation lock option is turned on. In order to turn that off and fix the issue, please follow these steps:

    1. Press Windows key + A on your keyboard to open Action Center.
    2. Click the Expand button.
    3. Click the Rotation lock to turn it off.

    Let us know the result for us to help you further.

    Regards.

    Hi,

    Thank you for posting in Microsoft Community, we appreciate your interest in Windows 10.

    I understand your inconvenience caused to you with accessing the second monitor, we will help you with this issue.

    This issue might have occurred due to outdated/ corrupted drivers.

    As you have already tried to update the drivers and issue still persists, I suggest you to uninstall the existing drivers for second monitor and re0install them from the manufacturer's website.

    Step 1: Steps to uninstall the drivers for the Display Adapter.

    • Press Windows key + X key when you are at desktop.
    • Select Device Manager.
    • Expand Display Adapter.
    • Right on the Display Adapter and click on
      Uninstall
      .
    • Restart the computer.

    Step 2: Also, contact the manufacturer's website and try to install those drivers for your device.

    You can install Windows 8/8.1 drivers in compatibility mode if there are no Windows 10 compatible drivers.

    Follow the steps to install in Compatibility mode:

    • Download the updated driver from the manufacturer’s website.
    • Right click the driver installation file and select
      Properties then tap or click the Compatibility tab.
    • Place a check in the Run this program in compatibility mode for: box.
    • Tap the drop down box and select a previous operating system, then tap or click
      OK.
    • Try installing the driver and check.

    Hi Max,

    • What happens when you try to connect the second monitor?

    • Do you receive any error code/message?

    • Have you tried to connect the second monitor on a different port?
    I suggest you to connect second display using a different port available on your PC and check if the second display works. If second display works in other port, then the possible cause for this issue may be discrete video card driver.

      Device Manager.

      Update Driver Software.
