Microsoft Remote Desktop multi screen Issue for M1 MacBook Pro

Hi, I'm getting the same issue on a 2021 16-inch macbook pro, using remote desktop 10.9.5. It was working in a previous version but regressed at some point. Using Sonny1201's workaround works for me, thankfully! My display arrangement is this, with my laptop at the bottom and 2 4k monitors side by side.

Thank you so much gietal, now it's working well even in my arrangement with the beta 10.7.9.

The fix is available on the latest beta client version 10.7.9 (build 2011). You can get it from aka.ms/rdmacbeta

Send us a screenshot of your display arrangement if you're still hitting the issue after trying with the latest build

same as Kejml_BV; when rearranging it fails again. my IT told me a new version was out 10.7.8; i installed but still having issues

mpgny Unbelievable! 😄

Unfortunatelly when I put it back to my arrangement it doesn't work again as before.

John_Spencer : I am using this arrangement:

Greetings. I have a followup to the solution. 

1) Quite Remote Desktop

2) Open System preference --> displays --> arrange monitors horizontally

3) Launch Microsoft Remote Desktop (10.7.7) 

4) Connect to your remote device (verify all screens are used)

4) Return to System preferences --> displays --> arrange monitors as desired. 

5) viola. 

mpgny  thank you for sharing your solution! 

John_Spencer This is my current display arrangement. Two extended monitor on top, side by side, and built-in display at the bottom.

Currently, my work around is to close my mac lid before I start the remote session, so when the session starts, I only have 2 display side by side, so the bug won't trigger, and I get 2 extended monitor in the remote session with good resolution. After the session starts, I can open my lid, the built-in monitor won't be connected to the remote session, but the 2 extended monitor stay with the remote session in a good state.

Here you go  John_Spencer 

Sometimes I had a third monitor as well with an iPad Pro on sidecar.

mpgny gfpcp Sonny1201 Can you send the arrangement of your monitors (through macOS settings) in the thread to help provide examples for developers to triage and debug the issue? Thanks!
