Hi,
My MacBook Pro 14 2021 M1 512GB is showing a 12" phantom display even though it is not connected and has never been connected before. It is showing at 1280x720. I tried restarting the Mac and resetting it to factory settings, but that didn't help either.
macOS Sonoma
Version 14.6.1
Thanks

If a simple reboot of your Mac doesn’t fix things, see if the problem still happens in Safe mode. It can take much longer to safe boot so be patient.
Start up your Mac in safe mode - Apple Support
Safe mode will often correct weird software behavior by forcing the OS to do disk repair, clear caches and other housekeeping and disables acceleration and third-party mods. When you're in safe boot, the machine won’t be at its best performance, especially with graphics, but that's expected.
Does the same thing happen while in Safe mode?
Exit safe mode by restarting your Mac normally and evaluate the issue again.

Unfortunately, in safe mode, as well as after rebooting, the problem remains.
There were also cases when the phantom monitor becomes the main display and I can't do anything on my MacBook, even after rebooting the screen is just black. The only way that helps is to connect via HDMI monitor and then make the MacBook display the main one again.
When I try to contact the official service center in my country, it says "We cannot fulfill your request."
Maybe you have other ideas on how to solve this problem?
