Windows 10: Monitors are both stuck on duplicate and low resolution. How do I fix?

I have two monitors setup individually with their own windows. After using my computer for a while tabs began flashing open and closed, computer began going a little slow, screens went black, then turned back on to all my tabs being frozen or closed with an empty error tab.

duplicating monitor

Hi,

Your concern about projecting your display to another monitor can be due to the configuration of your device and/or the setup that you're using.
To help us determine the appropriate troubleshooting steps that can resolve your concern, we would like to ask the following questions:

• What’s the current resolution of your display settings in your device? To check, right-click on the blank area of the desktop, choose
  Display settings and click Advanced display settings.
  
• If any, what error messages did you receive when selecting duplicate? If possible, can you send us a screenshot of it?

In the meantime, we recommend that you run the built-in diagnostic tool in Windows 10 or the Windows 10 Troubleshooter. To do this, follow the steps below:

• In the Search box, type Troubleshooting and press
  Enter.
• Click on Hardware and
  Sound.
• Find Hardware and Devices and click on it.

The troubleshooter will perform a diagnostic process on your system that will check and fix issues related to your device.
If the troubleshooter finds any issues, it'll be listed in the result with additional instructions you may need to follow. However, in most cases, the troubleshooter will find and apply fixes automatically.

Give us an update with the outcome.

 

Monitor resolution

Hi,



Thank you for posting your question in Microsoft Community.



I understand that you are facing issues with screen resolution. I will try to help you in fixing the issue.

To help you suggest more steps to resolve the issue, I would appreciate if you could answer the following questions:



What exactly happens when you try to change the screen resolution? Do you get any error message?



The recommended resolution on windows 10 is 1920 x 1080. Change the resolution to 1920 x 1080 and check.

The reason why your display was stretched sideways is because the resolution was in-corrected.



Here are the steps to change the screen resolution:

• Right Click the Desktop and select
  Screen Resolution.
• Click the Make text and other items larger or smaller link.
• In the Change only the text size section click the
  drop down menu to select the items you want to change.

Hope the information was helpful
