Hello everyone,
Synopsis:
When I run Windows via Parallels, the screen goes dark as soon as I click on any of my other monitors displaying Mac OS. This makes it difficult to copy information from the Windows environment to the Mac environment. My Parallels license is about to expire. I would like to get this resolved before I renew (if I can't get it working correctly, I will need to move on to a different emulator).
Hardware:
Mac Studio 2022 w/Apple M1 Max, 32 GB RAM
Monitor #1 (displaying Windows 11) LED Cinema Display at 2560 x 1440
Monitor #2: (displaying Mac OS) LG Full Display @ 1920 x 1080
Monitor #3: (displaying Mac OS) LG Full Display @ 1920 x 1080
Software:
Mac OS 26.3.1
Windows 11 v25H2
Parallels Desktop 26 for Mac Pro Edition v26.2.2 (57373)
Parallels Toolbox v7.1.1-4366
Details:
- When operating on the Windows monitor (display #1), all three screens display the desktops correctly.
- As soon as I click on either Mac desktop (displays #2 or #3), monitor #1 (Windows) goes blank. Monitors #2 & #3 continue to display Mac contents properly.
- When I click back on display #1's desktop, Windows displays again. Mac displays #2 & #3 continue to show contents properly.
- When Windows is left running and the Mac goes into Sleep Mode, I cannot wake it up. I cannot gain control no matter which display I click in. I have to perform a hard reboot.
- When I quit Windows, display #1 goes blank and the only way to get it back is to open Mac OS System Settings, go to Monitors and change the resolution. Once that is done, I can see the desktop on Monitor #1 and can change the resolution back to the initial resolution.
If anyone can offer advice on how to eliminate the blank screen issue, I would greatly appreciate it. Thanks.
