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

I am having the same issue, is this going to get resolved. I literally had this mac mini m1 for less then 5 hours. Every time it sleeps it restarts or the screen doesn't turn back on. Very disappointed with this purchase!

Haven’t had this problem on HDMI but I don’t like using hdmi because I can’t use the display as a usb hub. UsB C was fine too, but I recently switched to using usb c to dp (was told it’s better) - and it’s VERY annoying. Back to USB c I guess.

LOL, I don't have a problem with that. Just trying to get rid of as many variable as possible. If I had remembered that my adapter was not Apple, I would have done the same thing myself.

I AM getting frustrated about this recurring problem on a computer that is only 3 weeks old though.

This is interesting. How is using a USB-C hub any different than using an adapter? Why would that solve the problem? I used a Belkin adapter, and the Apple multipart, and still have some version of this issue. How does the mini hub make this any different?

As someone else has said, exactly what hub did you use, because if this works, you're about to make them a lot of money.

Thats bad...I have had no issue at all with this adapter.. I might be lucky..lol 😊

For reference, I am using two samsung 27" monitors for my mac mini with one monitor connected to the HDMI port on mac mini and the other to the HDMI port on the adapter...

As Apple currently only makes 1 display in the > $6000 CDN price point range, if they aren't going to be able to support sleep with third party monitors, this is a real problem for all mac mini owners.The OP is looking for support I think. Have you encountered this issue? What was your solution?

@hcsitas

I loose all my windows arrangements on my 5 external monitors plus have to reopen all unfinished work when am shutting down. If there was no sleep functionality I would live with it but if there's one that was working before that's not a solution for me then. Multiply millions of users that disable sleep and keep their devices running and you'll get the idea of how much electricity is wasted as well. If there was no problem with this functionality I'd not be wasting my time talking to you here.

But it IS a problem. I LiKE the sleep option. I use it every day. Whether it is "old tech and unnecessary" is beside the point. It is tech that is installed in a brand new computer and a brand new version of the OS, and expecting it to work correctly isn't exactly a wildly unrealistic expectation.

Or just turn my monitor off, then back on, for the two times (or so) a week that the problem occurs. Takes a whole two seconds, and is faster than shutting down and starting up, PLUS I still get to use the sleep function.

And in the meantime, I will definitely continue to bug Apple to have a machine that I paid over a thousand bucks for to work correctly.

But thank you for all of your concern. It means a lot to to me. It helps me sleep better at night.

I've got 3 identical Dell 2515H monitors which worked fine for over 3 years using the same HDMI cables on my MacBook Pro 17" (died one day), MacBook Pro 15" Intel 2019 (sold due to an upgrade to 16") and MacBookPro 16" Intel 5500M 8GB 2020 (sold due to overheating and loud fans issues once one external monitor was connected to it) on at least 3 previous Mac OS X. They still work fine on my spare MabBook Air i7 8GB from 2011 with Sierra 13.13.3.

Yes, but that’s not enough to pin blame on Apple especially as Dell is on record for not supporting Apple connection issues. As such, other than disabling sleep or shutting down, all you have is this discussion sadly...

Same experience here. Even though both my keyboard and mouse are wireless, I typically have to touch the keyboard to wake the screen - even with sleep mode disabled.

I'm using a product called MacID that lets your phone unlock your computer which takes any pain of this away.

Long time users of the platform will have some adapting to do.

This reminds me very much of when Apple changed the appletv remote so only one button would wake the device, instead of all the buttons. It's fine, but it doesn't pass the 'explain this to your grandparents' test.

This ones not a problem for me, but will be for many users. If you're used to moving a mouse to wake the machine (every Windows PC I've ever used does this) - this will contribute to a negative user experience.

Not following you here: "am loathe to switch to HDMI and lose HDR capability"

HDMI supports HDR. "HDMI® Specification 2.1 is the most recent update of the HDMI® specification and supports a range of higher video resolutions and refresh rates including 8K60 and 4K120, and resolutions up to 10K. Dynamic HDR formats are also supported, and bandwidth capability is increased up to 48Gbps."

I have the same LG 27UN850-W monitor. The spec on it maxes at 4k@60hz which is exactly the same max as the HDMI port on the M1 Mac mini. Granted, the USB-C port can provide greater resolution and refresh, but our particular monitor can't do anything with that extra.

Possibly, I am missing something in your concern, but I am not seeing a downside to the HDMI connection. Plus, it leaves an extra USB-C port open.

Thanks for that info, TrafGib, I'll give HDMI a try then.

I think I read another post about HDMI/HDR that simply wasn't correct. I do know that downgrading DisplayPort from 1.4 to 1.2 takes away HDR for me. I'm a bit fuzzy about the relationship between DisplayPort version and the various connection types (USB-C, HDMI).

My understanding was that 11.2 was supposed to address the sleep issue but it didn't work in my case. Just happy my current configuration seems to be working. Apple wasn't able to give me any suggestions that worked and they had me call BenQ and I was surprised that they are working on a firmware update that will hopefully address this.
