M1 Mac Mini, Displays wont turn on after wake from sleep

Thanks for your quick reply. Wow, I'm crushed if your advice is accurate. I am using an HDMI cable direct and it still won't wake. A new cable, high speed, and tested. You had five earlier with no problems, but they were Intel, and then your last one 18, has issues. Being a complete newbie to Apple, (well, I do have an iPhone 7) I am a little naive thinking this should not be an issue with their mighty 'flagship' M1. I'll jump through their tech tests and troubleshooting for a couple of weeks and then I will return it if nothing changes. Is waking from sleep an issue with their new M1 laptops too? Cr@p... Switching to Mac was a HUGE decision...lots of learning for me in a new OS, new office (pages, numbers...etc), printing, keyboard shortcuts, music apps, Photoshop... If anyone else reads this, does anyone have it waking up??? Let me know...

It seems like a right thing to solve the problem, I noticed a flaw, if you leave the monitor always on and put the screensaver on 10 minutes, a warning notification appears that the monitor will go to sleep before the screensaver, which may not be possible

DO you ever put your M1 Mac mini to sleep for 2-3 hours and the try to wake it? #1 Will it wake after that long? #2 is there ever a time where you tried putting it to sleep a couple times a day at 2 or 3 hours, and will it wake? #3 What LG monitor do you have? #4 do you have a screen saver turned on? Thanks

I have the same situation 2 macmini M1 1 in the office and 1 at home .... the one in the office has the problem and I can't find a solution, the identical one at home purchased 1 month later works. Now I don't know how to do it because the 14 days for the return have passed and I was confident in a software solution that does not seem to arrive at all.

Can anyone tell me how I can and if I can solve it? How should I do to get it replaced if possible?

Thanks

Yes. I installed it and the problem persists. The two monitors are recognized on startup but not when waking from sleep. I haven't had time to go through the two hours of instructions given to me by customer support. I am sure it will not help anyway. I suspect it has something to do with the display going to sleep before the mac recognizes it.

Works great!!! I was loosing my screen and was hard to get it back with my Samsung screen on my Mac Mini.

No more need to unplug and replug my usb-c or hdmi to get back picture, and my screen saver works now

My Macbook Pro 13 (2020 4*Thunderbolt 16G ram) also has this problem.

I contact Apple and tried all the solutions even go the service center. Still same !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I am using one of the M1’s usb-c (thunderbolt) ports to connect to a viewport monitor. My monitor does not support its highest resolution with hdmi input. I have not tried using an html to viewport converter; many of those seem to be unidirectional for an hdmi monitor.

Sorry but this cannot be the answer on the long term. I NEED and WANT to have separate spaces for each display, otherwise I don't need two separate displays. Reducing the extent of functionality cannot be a solution! The problem needs to be solved on Mac OSX. And this case simply hasn't been taken into account by the developers. So please Apple get a solution to this, because this seems to be a serious problem with more than 600 people having the same issue.

Well, I have just installed Big Sur 11.6 update. Not sure yet if it's solve the monitor not waking up problem but I get theimpression that it has introduced a new one... when I wake the computer, application windows sometimes seem to have moved from the screen they were on when I put the computer to sleep - and I have to move them back to the monitor they are supposed to be on.

I have the same problem but slightly different.... Thank god I thought I was going mad!!!

I have just bought a second 2018 Mac mini connected it to ONE Samsung 65" tv. Everything works fine but if it goes to sleep at night it won't come back on with the press of a key or the movement of the mouse. I have to reset the Mac mini for it to boot again????

I am just using a HDMI lead, which I know works perfectly as it was on my 2013 Mac mini setup for years and I never had this issue.

I have tried turning sleep off but, nothing!! It simply says on the screen that the tv cannot find the source and shows a powered off button.

Im on Monterey 12.0.1.

Is there a solution to this as I have only switched my old Mac mini to a newer version and now have problems??

Er, it is actually. Sleeping the mini gets you nuthin’! Think of it as a vaccine with no side effects...

I am not looking for sympathy. This powerless user is just looking to find someone who might have knowledge of a display issue using a Mac mini with M1 chip.

I have the same issue on my M1 MacBook Air, it may be a general issue with the new M1 macs—"Prevent computer from sleeping" does not help.
