A new report says some M1 Mac mini users are experiencing issues with external displays.
Some customers who have purchased an M1 Mac mini have been experiencing an issue that causes the machine not to wake a connected third-party display from sleep.
This is not an issue that’s affecting all M1 Mac mini owners, but there are numerous complaints on the MacRumors forums and the Apple Support Communities dating back to November when the Mac mini was first released.
One reader described how their Mac mini would not wake its displays after sleeping despite using two different displays and two different cables, another user explained:
I have a new Mac Mini M1 with 16 GB of RAM running Big Sur 11.2.3 and every time the computer and screen go to sleep, the computer will not be able to wake the screen up.
Actually, I get “No Signal” displayed on the screen after the Mini wakes so technically the computer wakes the monitor but it fails to send a video signal. The screen is a 34″ LG Ultrawide 4K Thunderbolt. It wakes fine with my 2018 MacBook Pro so there’s nothing wrong with the display itself.
That user said the only fix they had found was to unplug their Thunderbolt cable and then plug it back in. The report says the issue is affecting users regardless of which port they use, Thunderbolt, HDMI, or DisplayPort. Apple is reportedly aware of the situation, but the only possible fix in the meantime is the unplugging solution or disabling the sleep function.
