I found a workaround for my situation: I set the same scale for both laptop and second display to 100%. In this way it is correctly restoring. So the issue for Hyper V is restoring from scaling.
Hyper-V: full screen on dual monitor does not restore correctly
Hello,
I have a host machine running Windows 10 pro 21H1, with a guest VM also running Windows 10 pro 21H1.
The host has two monitors (1440p).
When I run the VM in full screen mode, it maximize the enhanced session window and it fills the 2 monitors correctly, but if I minimize that enhanced session window and try to restore it again, the session only maximizes on a single host window, which is a problem since it should maximize on both monitors, not just one.
The only workaround I found is to close the session and reopen a new one, that takes a lot of time specially I need to login to the VM every time I need to do that.
How can I restore the session to full screen on both monitors without the need to close it first? The solution described in another case does't help me (https://social.technet.microsoft.com/Forums/windows/en-US/c95e831d-36ae-4307-b3fd-a9daac6b5790/full-screen-on-dual-monitor-does-not-restore-correctly?forum=win10itprovirt).
Thanks

2022-10-21T16:50:42.903+00:00 I found a solution that works for me:
- In the VM window go to View and uncheck Enhanced Session. The VM window will become small
- Go back to View and check back the Enhanced Session. Now the VM window is full screen properly on both screens.
My config:
- Host: latest Windows 11 22H2
- VM: Windows 10
- Using two screens.

2023-10-23T13:12:00.6266667+00:00 I have the same problem. On Windows 8 it worked flawlessly and fast. Started to occurr in Windows 10 and got even worse in Windows 11. On top of mentioned window reshuffle whenever I switch to a fullscreen Hyper-V window both screens go black for about 5 seconds, only mouse cursor is showing
Suggested steps did not help. Scaling matches, re-enabling Enhanced session didn't help. Renabling fullscreen in Session Settings didn't help
I've been trying to solve this for 5+ years, no one knows what to do with it
