Has anyone been having issues with Luna display only mirroring the ipad screen with the laptop rather than properly extending the desktop to form a dual display? Whenever I initially plug in the device, the screen flickers and I get a mirrored screen. After unplugging and replugging the device, I finally get the proper dual display effect. Sometimes, I need to select a different usb-c port in order to get it to work properly. Please help.
it is possible you have “Mirror Displays” checked in your Mac system preferences. Maybe it even keeps track of this setting per port? if you go in “System Preferences > Displays > Arrangement” there is a checkbox below the picture “Mirror Display.” Uncheck that.
