Dummy screen is set to be a main display and is invisible?

Macbook pro screen is struck after changing resolution. From then on when ever I open the app the screen is being struck and I have to restart the system

Hmm. I'll need more details on the setup and on how to reproduce the issue exactly. If you can do a video about the issue I might better understand what is happening. Thank you!

Hi @ktssr - I think the dummy display is set to be the main display and it takes all the windows. The macbook display is set to be an extended display. The dummy display is invisible as it is not mirrored to anywhere.

You can open System Preferences/Displays and set up mirroring there or if you download BetterDummy v1.1.0 you can peek into what's on the dummy display using the Picture in Picture functionality and act accordingly. You can also use the v1.1.0 to configure mirroring via the app menu.

Hope this helps!
