Windows 10: Monitor disconnect from PC when I switch it off

I got a new monitor about two weeks ago. ASUS TUF Gaming VG259QM Usually I will switch off my monitor when I don't use it for a short period of time without closing the PC, so I can resume where I left off ASAP. Recently I realized the color on my monitor is off whenever I switch it back on. I adjusted some color settings in the NVIDIA Control Panel in the "Adjust desktop color settings" tab. Every time I check the settings are the same as I set them, but they're just "off". Like how the gamma is lower than what it should be. I set it to 1.5 I can simply fix them by dragging the slider to

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,

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.
