Can not use Windows duplicate mode with Spacedesk Virtual Display anymore

I am using Windows 11 on a new system since last week. My old system used Windows 10.

After installing spacedesk on windows 11 I cannot use the “duplicate display 1” mode on the spacedesk display like I was able to on Windows 10. I have checked every setting in the iOS viewer, Windows driver console. Can you guys make it compatible again?

 

Here is a diagnostic if you need one.

Hi @just-2,

Thank you for sending your logs. Upon checking them, we didn’t see any problems with spacedesk.

In very rare occasions, errors with the Windows Display database cause issues with screen extension and duplication, so we have a button in the spacedesk Driver Console called “Clear Windows Display Settings” which you can click to fix any issues in the Windows Display Settings that includes the issue you’re encountering with display duplication, but be warned that clicking on it would also clear your previous settings like monitor arrangement and other settings in the Windows Display Settings.

Hi,

clicking this “Clear Windows Display Settings” button within spacedesk does not appear to have any effect.

The screen is still only available to extend via display settings.
