External monitor blanking often

Hi,

Please answer these questions to assist you better.

• What is the make and model of your computer and external monitor?

Step 1: I would suggest you to check and install any latest Windows Updates available.

• Go to Start and then Settings.
• Click on Update and Recovery.
• Check for updates under
  Windows Updates.
• Restart the system and check if the issue is resolved.

Step 2: Please refer to the following Wiki article created by
Andre Da Costa on How to: Install and Update drivers in Windows 10.

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
