iPad, Sidecar, and Horizontal Flip (Mirrored)

[airbeat]

Hi there! I've folllowed a few tutorials to use my iPad as a teleprompter display. As far as I can tell, there's no way to just horizontal flip the display outright (I see I can rotate, just not flip), so we need to create a virtual (dummy) screen, associate it to the Sidecar/iPad display, and then arrange the screens in the system preference pane so that the iPad is "farther away or on the other side of" the virtual display. This generally works, but I want to ensure that I have it as best as it can be:

1. The display is not very responsive--as if the software is working hard to do what it's doing. I don't need super high resolution, it's generally just displaying a Teams or Zoom window.

2. Is it correct that you have to stream a virtual display to the real display and have them both as screens? Is there any way to remove the iPad screen so that there's only one screen with the content? Sometimes an application window will get trapped on the iPad screen that isn't actually visible--because I'm streaming the virtual screen to be shown on the iPad.

Streaming the display should generally have no performance issues. The streaming itself takes up marginal resources so if you see framedrops, it must be the iPad connection itself. Make sure you don't connect the iPad wirelessly as that might reduce performance. You can also try playing some random full screen high resolution 60fps video from youtube and see if that looks smooth to double check the performance.

Thank you! Any thoughts on preventing stranded app windows that get lost on the display that isn't displaying its own content?

Sure, just use the keyboard shortcut (assign one) to hide/uhide the stream any time quickly.
