Windows 10: Windows 10 keeps setting third monitor to "Disconnect this display" on boot

I have 3 identical monitors, two of which are connected via DisplayPort, the third one uses HDMI:Monitor setup and connection from left to right as displayed in Windows3 - HDMI2 - DisplayPort main1 - DisplayPortEach time I boot Windows monitor 1 which is the one on the right is set to "Disconnect this display". When I manually select "Extend my desktop to this display" everything is fine. But why should I have to do this on every boot?Resolution and scaling are identical on all 3 monitors.For some reason Windows seems to think that monitor 1 runs at a refresh rate of 59.997 Hz nVidia Co

External monitor display settings

Hi,



Thank you for posting in Microsoft Community.



I understand that you are facing issues with the display scaling on your external displays. We will certainly look into this for you.

As you are using Vizio TV, you may have to try using custom resolution settings if the in-built settings do not provide the required settings.

For better clarity, please let us know:

• What is the version of Windows 10 that is currently installed on your computer? You can click on Search and type
  winver.
• Are you aware of any recent changes to the system, such as updates, after which you are facing this issue?
• What is the make and model of your computer?

Meanwhile, I would suggest you to check the steps mentioned in the Workaround section in

Windows scaling issues for high-DPI devices

I would also suggest you to check the Display drivers. Please refer

Let us know how it goes.

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,
