It wakes fine with my 2018 MacBook Pro so there's nothing wrong with the display itself. The screen is a 34" LG Ultrawide 4K Thunderbolt.

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.Īctually, 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. MacRumors reader Mike, who emailed us about the issue, has seen the same problems. I also noticed some pink squares/graphics glitches on the Big Sur boot/log in screen (with the coloured background, not the black and white boot up) I have tried with 2 different displays with 2 different HDMI cables with the same thing occurring on each one. My M1 (8gb/256) Mac mini doesn't seem to want to wake my displays after its been sleeping. 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.
I tried the HDMI solution below after the issue of my monitor not waking up from sleep mode started happening again sporadically, so the workarounds above were not a permanent fix if anybody was wondering.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. It's odd that a keystroke on startup can make the display wake up normally but that it fails without it.

However, when rebooting (power cycling) afterwards, I still had to type my password into a blank screen. After that, the password screen came up normally! I pressed it at about when the first chime occurred and waited for the second chime before letting go. I tried resetting my NVRAM by pressing Command+Option+P+R on startup. How do I make my Mac Mini play nice with my display?
Also, for what it's worth, when I boot up and the OS re-opens my windows, they are all clustered in what appears to be a 1280x1024 box in the upper-left corner of my screen. I've speculated that maybe the FileVault boot screen can't handle the 3440x1440 resolution, but that seems like a serious oversight if true. Is there a way to make sure that my display always works? However, the issue remains when I power cycle. Ultimately, I was able to resolve the sleep mode issue by powering down and unplugging the Mac (I read that this would reset the SMC). I'm asking about this now because I recently upgraded to macOS Sierra and was disappointed to discover that the monitor would refuse to wake every time the system went into sleep mode! (not just when power-cycled) Also, I normally keep the power on so it hasn't been much of an issue. I normally only use the one display though, and it's been about a year since I've hooked up the other one thanks to this workaround. I thought of this workaround after connecting a 1280x1024 monitor to the mac alongside my regular 34-inch 3440x1440 display (second display worked). The only way I can get it out of sleep mode is to type in my password and press enter with the display still blank (power save mode). No combination of keyboard presses, connecting/disconnecting peripherals, power cycling the monitor, etc. My issue is that whenever I power cycle my system, the display remains in sleep mode (monitor LED slowly flashes white versus solid white when it's on / Mac LED is solid white). I am using full-disk encryption with FileVault. I'm running macOS Sierra, but had the same issue in previous versions. There are no other displays connected to the system. My keyboard and mouse are connected via the monitor's built-in USB hub. I have a late 2014 Mac Mini connected to a 34-inch Dell U3415W display via Thunderbolt to DP.
