Windows 10: External monitors?

I hope this Q about Win10 features doesn't cross over the "no tech support" line.

I use a Dell laptop and one external Acer flat panel monitor. I believe I have "extended the desktop".

I wish I could add a third monitor. Somewhere years ago I thought I learned that windows could only extend to ONE external monitor. Is that still true?

Please answer these questions to assist you better.

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

Do let us know if you still get random black screen in the external monitor. Thank you.

 

External Monitor with Quicken

Hi Mark,

It is possible that the display resolution automatically adjusts after connecting to an external monitor. For us to properly isolate this issue, we have some questions for you:

• Are you experiencing the same issue even without using the Quicken tool?
• Have you checked if the display resolution settings of the Surface device and the external monitor is the same?
• Have you tried checking for a graphics device driver update?
• What troubleshooting steps have you done to isolate the issue?
  

We're looking forward to your response.

 

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.
