I am trying to get my external monitor to work with Parallels 18. All works fine on my laptop MacBook Pro M1 running Sonoma 14.6. Please give me instructions on what to do. Perhaps there is already an answer in another Forum.
It sounds frustrating when your external monitor isn't working with Parallels 18, especially when everything else runs smoothly on your MacBook Pro M1! First, make sure Parallels is fully updated and compatible with Sonoma 14.6. Then, check the display settings both on macOS and within Parallels. Sometimes toggling "Use All Displays in Full Screen" under Parallels settings can help.
