M1 Won't Wake External Monitor

Strange you haven't hear about apple.

Today I have try this MacBook with the iiyama game-master monitor and everything works fine.

So my guess is that this problem is not with all monitor's just some models having a problem re connection after sleep.

Another thing is that the Anker doc is also involved and I hope that the apple multiport from apple is doing the trick then my problems are solved, if not have to wait for an apple solution.

Also read that the mini Mac and de MacBook Pro m1 haven the same issues on some monitor's

What kind of connection to the monitor?

I have the same problem. There is nothing wrong with your display - I am seeing comments relating to this for all M1 based computers. My Macbook Pro works fine with my display.

The one thing that works almost every time is:

unplugging the display, shutting down the mac, restarting the mac, logging in, and then finally, plugging in the display.

Far from ideal. Eagerly watching for a software update that I hope fixes this.

Jup same problem here with my MacBook Air m1 and a Samsung 4k monitor U28E570 connected with a doc from Anker.

After sleep the monitor is not waking up most of the time and the methode mentioned bij zuluimpi is working most of te time, sometimes a double in/out from the usb-c the connector is required.

Never had connection troubles before (ps4, MacBook Pro 2012, iMac using thunderbolt) and plenty other devices.

I have order an original Apple USB-C HDMI Digital AV Multiport Adapter (latest model) and hope for the best.

I hoop apple wil fix this soon because it's very annoying.

Do i have to report this issue somewhere ?

I am very frustrated with Apple and this computer. I am having the same probelm with the monitor not recognized and was one of the first to report it here several weeks ago.

At the same time called Apple Support and asked for a replacement. The Apple Support person was absolutely dismal - told me the return period has expired even though Apple stated on it's website it would accept returns and replacements until January. I told what he said was not true at all and pointed him to the apple website. Then he 'remembered' didn't apologize at all said I'll receive a replacement.

I told him that I need to receive the replacement before returning this one because I use the computer for work.

He said sure it won't be a problem.

Sure... the order I received said the replacement would ship by January 7th so I just checked... Not shipped - On Hold!

Why? replacement no received

Apple of course has not fixed the problem with the second monitor not being recognized.

I really don't appreciate this. In addition to the normal arrogant attitude they leave defects and don't stand by their word.

Last time I had to write a negative review about apple due to it's unfair pricing policy they gave me **** when posting a new app in the app store. Well, I will now write a letter to the CA reps.

We're experiencing a similar issue with our new M1 MacBook. When waking, the monitor fails to pick up a video signal. Disconnecting the cable, then plugging it in again has resolved it most of the time, but that's not an ideal scenario.

Other, older MacBooks, don't have the same issue. It's just the 13" M1.

Wow, when they say that Big Tech censors free speech, they are not lying. I can’t believe I got moderated here fir quoting what Apple engineering wrote in the trouble ticket that I opened on this issue. In all my decades of using Apple products and being an Apple shareholder, I’ve never seen anything like that. Scary stuff.

We have seen a case recently where a DisplayPort display worked fine at 60 Hz when its internal spec was set for DisplayPort 1.2, but when its internal display settings (in the display itself) were changed to DisplayPort 1.4 (which allows data compression) the display dropped back to supporting only 30 Hz refresh rate.

My guess is that it could not quite keep up with data decompression at the higher resolution.

The specs for DisplayPort 1.3 and later ALLOW FOR for the use of data compression.

Whether it is actually in use is not the point. Some Display-makers took it very literally and dropped their supported resolutions when it was POSSIBLE they might see compressed data (specifically the need for the display to also do high-speed data decompression at speed for a high-resolution display).

Apple contacted you?? I'm having the same issue with M1 and is annoying as ****, I don't want to try every docking station or monitor if is something about Mac firmware update that needs to be fixed ASAP.

Far from ideal????? The Apple II E was 40 years ago. Apple has had 4 decades to get its act together. These things should work. I went through all the trouble you mentioned (for the umpteenth time), and my MacBook fell on my desk when putting it into the stand, damaging my desk. Totally unnecessary. 40 years...

Today is April 26, 2011. Apple has just released macOS 11.3 today. It has fixed my issues with the 5K display not being detected from the M1MacBook Air via DP1.4. Once I upgraded from 11.2.3 to 11.3, the 5K Display was detected via its DP1.4 port and a DP1.4 cable (USB3 male to DP1.4 male). The same cable didn't work with macOS 11.2.3, 11.2.2, 11.2.1, or any other previous version on macOS 11.x

I got a call from Apple yesterday. They collected additional information on behalf of Engineering and then sent it back to Engineering.

good, well so there are issues and I hope more driver updates wil come, hoping soon ;-)

Apple has been arrogant like this foe a while now. Probably over a decade. You be learned to deal with it and not expect much from Apple. Because the alternative is even worse.
