Studio Display Will Not Wake From Sleep

I may have hit on a super simple solution.

Set one of your Hot Corners to "Put Display to Sleep". I set mine for the lower right corner. Then, when my display won't wake up I just mouse down down down (to make sure the mouse is at the bottom) then right right right - and as soon as it hits the corner - boom - the screen comes on.

Works every time so far. 👍🏼

This did not work for me. Not sure how it could. When the display won't wake, the computer is pretty much unresponsive. No amount of keyboard tapping or trackpad clicking will get it to wake up, and mousing down to the hot corner also does nothing.

This issue persists for me and is occurring more frequently (now happening even after short period of computer sleep).

I finally contact Apple support today. On giving them the serial number of the display, they immediately told me "At this point your device needs to be serviced." I was given options to 1. mail it in, 2. Drop it off at Apple store, or 3. Be connected with a senior support to walk me through more advanced troubleshooting.

I opted for taking it to an Apple store and will be doing so today. I'll report back on anything I find out.

It seems like the only way service will solve the issue is if they’ve fixed a hardware issue that has plagued new displays for months, because I purchased two brand new ones that both had the issue.

My “solution” was to return and settle for a $400 LG 27” 4K w/ p3 color and a Caldigit TS4. I may not have 5k resolution but I paid half the price and my monitors actually wake from sleep. I can’t believe how many issues the Studio Display has had. I will revisit Apple Displays when they release a mini LED display that hopefully doesn’t run an OS.

I agree that it's the monitors, but why is the question.

I had a mini back in 2018 that had the same issue with Samsung 4k screens. Now my brand new Studio can't wake my Monoprice 49" Dark Matter. It's very frustrating.

But I've had good luck using the trick I posed above using the sleep Hot Corner to get the display to wake without a physical reconnect or reboot.

a common work-around for not waking from sleep is to give the mis-behaving display a 'timeout'. Sit it in the corner, facing the wall, with no power or data for a quarter hour. In that time, it will do a deep reset, and may be more willing to 'play nice with others' when it returns.

Follow-up. Apple genius bar had my studio display for 2 days and were unable to replicate the issue.

Has anyone been able to reliably trigger the problem? This would help with troubleshooting. I was having some luck triggering the problems on my Intel 2018 MacBook Pro by manually invoking standby mode (sudo pmset -a standbydelayhigh 60; pmset sleepnow). Then, my bluetooth keyboard would wake the mac before 60 seconds of sleep but would not wake after 60 seconds of sleep. At some point during this testing, macOS rebooted for some reason during sleep, and I have not been able to trigger the problem using this method since. Maybe it is a bug that manifests after some degree of runtime? Unfortunately, these pmset parameters can not be modified on Apple Silicon Macs.

I have the problem mostly every time (may be 80%) I have MacBook Pro in sleep for couple of hours. Usually when I wake it up shortly (e.g. within an hour) after it was put into sleep, it works. But I have not done any extensive research. For me the workaround in the previous post works for me.

to get a Mac display to become active, you need the Mac to query the display, and the display to answer with its name and capabilities. Otherwise, the display will not be shown as present, and no data will be sent to the display. "No signal detected" is generated by the DISPLAY, not by the Mac.

This query is only sent at certain times:

• at startup

• at wake from sleep — so momentarily sleeping and waking your Mac may work

• at insertion of the Mac-end of the display-cable, provided everything on that cable is ready-to-go

• on invoking Option-(Detect Display) button in Displays preferences (from another display)

if the display misses the query upon wake-from long sleep, it may remain dark. Replugging the cable would be a solution, but some of the others on that list may be less intrusive.

You won’t find a solution here, just depressing workarounds, if you can even call something like unplugging the cable a workaround.

Return it while you can! The compromises are not worth it and Apple has had 6 months to fix it already.

I totally agree. When I turn monitor on and off, it does not see a signal and will return to sleep mode shortly after. When I unplug and reconnect the thunderbolt cable, the system wakes up..

This is a new mac studio so I will pursue it from support perspective.

I found a solution that works for me. Like others, in deep sleep, monitor would not wake up *LG wide screen 5K, and I had to either reboot, or pull video cable out and in. Always in the morning this would happen for sure given he time in between. Last few days have been great and my monitor wakes up reliably.

My solution: System setting/ Displays/ advanced/ Energy: Prevent automatic sleeping when the display is off (toggle off!)

My studio still seems to go to sleep along with the monitor and both wake up ok..

Same issue here. Started happening only recently, have had my macstudio for about one month now. Go away for several hours, come back, and I can't get the system to wake up. Am using a cabled Apple keyboard and bluetooth Apple mouse 2 with two non-apple displays. Tried unplugging and replugging in each individually, didn't help.

Today, after reading the above thread, I unplugged ALL of them, both displays and keyboard, replugged them in, and THEN the macstudio finally woke up.

Happened again the next night, but wouldn't wake up this time no matter how much I tried to disconnect and reconnect peripherals. Finally had to hard boot the mac using the power switch. VERY annoying! I have loooooong processes going, as is required for all of the installations involved in migrating from my old mac to this macstudio, and having to hard boot the computer completely disrupts some of them, having to start over. This does NOT bode well for upcoming movie renders (Premiere, eventually DaVinci). If this bug disrupts a process that can take multiple days then I might never be able to get a process like this to complete. My beautiful macstudio might not even be capable of one of the main reasons I purchased it. If THAT starts happening then there may be some unfavorable Youtube posts... but first, I'll call Apple support. Generally those folks are very helpful. Crossing fingers...

so try doing some of those things and see if the display comes alive.
