Studio Display won't turn on!

The problem for me was plugging the thunderbolt cable into the wrong port, apparently it can only be put it in the port with the lightning symbol above it, so I had to plug it into the max studio with the lightning symbol port and plug it into the stufio display port with the lightning bolt above it

Having exactly the same issue. Had it on for less than 6 hours before it bricked. I left it while my MacBook Pro was sleeping and when I can back to it, it said the display switched off because of a problem.

I now get the three dots when I switch it off and on again at the mains.

It’s still charging my MacBook Pro but it’s clearly not working as it’s not doing it consistently. It’s charging then not charging. Charging, then not charging.

Really not great…

I had this issue also, it's just resolved itself.

I am on Monterey 12.3.1 (newest at time of writing)

What I did was unplug the display from power, let it sit for a few minutes, plug it back into power, then put the thunderbolt 4 cable into the display and then into the laptop.

But this only worked after letting it sit like that, plugged in, for like 5-10 minutes.

Also one time literally just switching which end was plugged into the display fixed it...

I don't know if it is required to do this every time you switch macs, which I planned on doing a lot of (thunderbolt is supposed to be the ultimate universal port, right?) but it is unacceptable for this to occur every time I switch macs. (As it has, every time I've tried to hot swap them.)

Especially costing what it does.

I had this problem today, plugging my laptop into the monitor – just three dots then a blank screen, but my laptop was charging.

It turns out there are USB-C ports on the back of the monitor. Only ONE of them has a Thunderbolt (lightning) symbol above the port. You need to plug into this one for it to work.

(Junior colleague had borrowed the cable to charge her iPad and plugged it back into a different port!)

I got my brand new Studio Display (with 15.4 already on it), from the Apple Store today and experienced the same behavior with both a 2021 14-inch MacBook Pro, and a 2021 iPad Pro 12.9. Nothing but flicker on/pod and the three dots when powering on.

However, as soon as I switched to the Thunderbolt cable that came with my old LG Ultrafine, everything just worked. Will be contacting Apple Support for a new Thunderbolt cable because those suckers ain’t cheap and should work out of the box with an expensive monitor like this!

Got my display yesterday, today I had the same thing happen. Unplugging & restarting Mac helped but obviously this is unacceptable. Did you get any resolution or insight into the issue?

At one point I got three flashing white dots on an otherwise blank screen - not sure what that indicated. Firmware update?

I had the same issue i swapped the studio display again the same issue , I restarted not working and tried connecting the the thunderbolt cable to the studio display port with lightning bolt above it and now it is working and also updated the latest firmware , Thank you

Mine won’t even stay on, it turns on for 6 seconds with 3 pulsating dots and then it just turns off, gone through Apple support for an hour and it’s so new they don’t know much about it. Tried connecting it to the mac studio and a new iPad Pro, does the same thing. (referring to the Studio Display)

I had exactly the same issue. I would only get the three flashing dots after powering up the display and then it would go black. Tried a different cable, different machine, even plugging in my iPad wouldn’t turn it on.

I spent an hour with support and then they eventually sent me a replacement.

I suspect it was a corrupted auto firmware update overnight that bricked it.

Mine is doing this too. Oddly enough the display is the only part that isn't working. It turns on for about a second before going black. The speakers, microphone, and webcam work, just no video.

I'm using a 2021 mbp 16. The apple support technician I was on the phone with had me try it with my iPad and I had the same issue there.

Just got this delightful error report (well, this is just a small snippet) when it said the screen turned off because of a problem. Got to love a report that starts with the word “panic.”

Yeh. I left it unplugged for about an hour last night before trying again.

I left it plugged in to my MacBook last night in the hope it might update but it seems to actually be rebooting the laptop too.

I've just figured out how to fix mine. My set up is a MacBook Pro 16 inch (2021), so this might only apply to me.

My understanding was that I could use the Studio Display (nano textured glass version – if at all applicable) to keep my laptop charged while I was using the whole set up. So, I didn't have the MagSafe power plugged in. This morning, I fully unplugged the Studio Display from the wall and MacBook – assuming I'd need to start thinking about returning it. I put my MacBook on charge using MagSafe. Then, I tried the display one last time and it turned on. Assuming it was somehow fixed, I took the MagSafe charger out and put it back in my bag. Right away, the Studio Display turned off. MagSafe back in, the display turns on.

I'm assuming it should charge my MacBook though? So this still feels like a real miss from Apple. At least it's working so I can actually do my work today.

Hope this fixes everyone's issue. Apologies for the novel, I just wanted everyone to potentially recreate the issue if needed.

I got my Apple Studio Display yesterday and had the same problem here. I have an M1 Mac Mini with 2 monitors attached (one is a Cintiq 24 HD display). When I switched out my secondary monitor for the Studio Display… 3 dots and a dark screen. The Cintiq synced just fine with both monitors attached (I’m using a converter cable for the Cintiq that is DVI to USB-C) After much fiddling, I removed all of the displays and just attached the Studio Display. It came up right away, but when I attached my Cintiq no sync. After some more fiddling, I switched the converter cable on the Cintiq from DVI/USB-C to DVI/HDMI, and everything works swimmingly. I hope this is some help.

In my case, I replaced my previous 27" 4K monitor with a Studio Display on my iMac 5K 2017 and it was pitch black and nothing showed up!

I had a RAID storage Drobo 5D3 connected to the Thunderbolt 3 port, and when I disconnected it, the Studio Display appeared, then I connected the RAID storage, and both were connected without any problem, and there was no problem when I woke up from sleep.

I contacted Drobo and they said it could be due to power consumption or bandwidth.

Is there any other connection to MacBook pro 13"?
