Airplay extended display - rotate screen

[miszterx]

Hi,

I am looking for solution to use airplay display with extended mode and rotate the screen. Unfortunately just landsape mode resolutions are selectable.

Is there any way how I can use portrait resolution on the remote screen with airplay?

Hi there, you can't simply rotate AirPlay displays I am afraid. What you can do is you connect to an AirPlay display, create a dummy, set it to portrait and then stream the portrait dummy to the AirPlay display with 90 degrees stream rotation.

You should essentially follow the same tutorial as with Sidecar rotation, but instead of Sidecar use AirPlay: #1086 #872

Let me know if this works! :)

It worked partially.
However the main issue is the resolution on the airplay side. Even if I rotate the dummy picture and stream to there, the airplay resolution would be the same. So I can stream a BIG rotated resolution into a small picture where the top and the bottom is black.

So it seems to be the airplay layer resolution cannot be changed even with betterDisplay :(

what device are you streaming to?

but yes, it seems like AirPlay is 16:9 only. I wasn't aware that this is an actual hard limitation especially after AirPlay to Mac was introduced, it's a bit odd...

(Samsung M5 monitor) I can see this:

Yep, just 16:9 resolutions are available. I also submitted feature request to apple, but Probably i should give up on this. :(

I tried to mirror the Virtual to airplay display. It can work. The problem for me is that the clarity has dropped a great deal.

Yes. Afaik airplay resolution is fixed at 1080p so if you mirror your screen, it will be downscaled to that resolution. But why are you using AirPlay?

My MacBook Air can only be connected to one external display. I want to add one more display through AirPlay. Moreover, this additional display is a vertical screen.
