Studio Display wakes up from sleep mode with a reduced desktop area and the dock displaced

My Studio Display with Mac Studio 2022/32 GB wakes up from sleep mode with the desktop's wallpaper - or either a grey or black wallpaper-like area - reduced to around 2/3 of the entire screen, and the dock displaced at the bottom of this reduced wallpaper area.

I gather it's not a matter of display resolution because the entire screen, even outside the reduced wallpaper area, keeps being active and folders keeps being there at their place.

I brought the Mac Studio to an Apple shop in Rome, Italy, and they couldn't suggest any solution except update the OS system.

I updated to Sonoma but it keeps happening.

After reading other threads (Studio Display Will Not Wake From Sleep - Apple Community and Studio Display will not wake from sleep. - Apple Community), I tried all the suggested tips and I can confirm that unplugging the thunderbolt cable from the Display and plugging it back, is the only workaround that it works for me, and even so, the desktop lags a couple of minutes before restoring back to its normal width.

Any suggestion will be highly appreciated,

Adriana

Your symptoms suggest that as your Mac is starting up, the system detects your display size at a smaller size, then slightly later, it gets reset to actual size. It suggests to me that something may be coming up too late to be recognized when it commits to wallpaper size.

I suggest you use Option (Detect Displays) button in the displays control panel to see if clicking that will set the display size right again.

--------

What is really wonky about yours is that the notifications and menuBar (and is one picture the desktop icons) eventually continue all the way to the corners, while the Wallpaper and Dock stay in a reduced area.

There is also a suggestion that in some cases, a very high resolution display uses two streams of DisplayPort data to address the screen in two 'side-by-side' "chunks" which are then re-assembled (in the display) into the complete picture. I have no idea whether this display uses that technique, it just reminded me that some displays might, and having one of the streams fail or be unreliable for some reason might give you similar results.

Unplug the display (no power) wait 5 minutes then plug back in and test.

Unplugging the power cable is not the same as unplugging the TB cable. It resets the display internally.

if you do NOT use the Mission Control "Displays have separate spaces" feature, you might try turning that OFF to see if results are any different:

Many users have issues using the sleep function (including myself). I do not use sleep and only have the display turn off after a set time or use a screen saver. Not a solution but a temporary fix.

Thanks for your insights Grant.

I tried clicking Option (Detect Displays) button but it didn't work.

And yes, I use Stage Manager although I always did, even before this issue happened. I only have one monitor connected.

I've been talking to the Apple support three times now, tried many possible solutions, nothing worked so far.

One possible culprit might be an app, SonicWall Mobile Connect - a vpn to access one of my clients' server - which I installed the day before the issue started.

I deleted the app today but many Library files were still nestled around. So the Apple guys helped me manually finding and deleting each of these files.

It seemed finally solved but after a few hours the same problem was back there.

Next step is re-installing the os system.

As I said, the only workaround that works for me is unplugging the thunderbolt cable from the Display and plugging it back, so unplugging the power cable is pretty much the same. Yet I don't think a monitor worth 1700 € should work this way.

Thanks Grant,

Tried that too, it didn't work.

By the way, if "Displays have separate spaces" is toggled off, Stage Manager switches off too and its toggle is greyed out. Hope this is the correct way it all works and not another issue on my Mac.

¿Do you use stage manager or Mission Control features?

This could be related to confusion over whether you intend all displays to be separate, or concatenated into one large "Extended Desktop".
