Unable to use iPad in portrait mode

[aminozuur]

I have a Mac Mini M4 on macOS Tahoe with a main monitor. I’m using my iPad 6th Gen in Sidecar mode. Sidecar only supports landscape view, so I installed BetterDisplay to enable portrait mode. I’ve been clicking around BetterDisplay and trying all kinds of configurations, with no luck at all. I created a new Virtual Display (I selected “iPad 4:3” from the dropdown list), and then streamed the virtual display to my iPad, but it still shows up horizontally. And when I select “Rotated orientation”, the iPad turns black. What am I doing wrong? I wish someone uploaded a simple and short step-by-step guide on how to set the settings to make this work. Any help is welcome. Thank you.

• I’ve tried restarting my Mac
• I’ve already unlocked the iPad itself in portrait mode

UPDATE!!
After an hour of frustration and just facing a black screen, I gave up. I went into the BetterDisplay and randomly toggled off my iPad display, when it started working! I am not even exactly sure what I clicked tbh. Now I am scared that whatever setting it’s set to now, which works, will be lost and I’ll have to puzzle it out for another hour the next time I restart my Mac. So any help or guidance is STILL WELCOME!!

You seem to be mirroring from the iPad to the virtual screen what you are then trying to streami back to the iPad - this will certainly not work.
