Parallels 17 MacOS 12 Guest System Fullscreen

Hi,

Im using the following setup:
MacbookPro 16 (2021), M1 Max, 64GB RAM
MacOS 12 (Monterey)
Parallels 17 Pro

Downloading MacOS 12 in Parallels, and use it as guest System.
Is it possible to configure parallels in full screen with MacOS 12 Guest System?
I could only use the guest system in a small windows ???

Thanks

Martin

 

I use Parallels desktop Version 17.1.1 (51537) and host OS MacOS 12-2 beta on a Mac Mini M1. I have a MacOS guest running 12.1 and I can run it in full screen, however the ratio seems to be 5:4 and the resolution is 1440x900. Parallels says they support MacOS guests on M1 but they haven't implemented all functionalities and settings yet. My questions it, when will MacOS guests on M1 be fully supported???
