Project Second screen constantly appearing.

Hi Norga,

Thank you for using Windows 10.

Let us know some more information so that we can diagnose and troubleshoot the issue in a better way:

• what is the exact issue that you want us to help with? Do you want to get help in projecting a second screen or to remove the popup?
• As you've said " I tried unsuccessfully to project a screen", do you wish to project a second screen currently?
• What happened exactly when you tried to project a second screen? Did you receive any error message or any error code?

The popup comes as the system might not be able to detect the monitors. I suggest you to update the Display drivers, it may force the system to detect the available monitors. Here is the steps:

• Press “Windows + X” and select Device manger.
• Locate the driver and expand the driver icon.
• Right click on the driver icon and click on Update.

Reply with the information and we'll be happy to assist you.

First, I would suggest you to check if you have configured the second screen correctly. It depends on which settings you have selected for the second monitor. You can extend, duplicate or choose only the second screen to be ON. If you have selected only the
second screen to be ON and if the second screen is not compatible, then both the screen might appear black. Refer to this article to check if you have configured the second screen correctly:
