My upgrade to Ventura (M1 Mini, 16gb) came with a heart-stopping moment at final reboot when my Pro XDR stayed dark. Several forced shutdowns and reboots did not fix the problem. I plugged in an ordinary HDMI monitor that worked, but nothing would make the XDR start.

Shucked my setup down to absolute basics (M1, XDR, keyboard, mouse) then restarted and to my relief, my XDR came alive. Rebooted several times and it still worked.

Lots of troubleshooting later, I found that my USB 3.0 hubs (2 of them) are the cause of the problem. Both were plugged into the monitor and have run for a year or more that way. Right now I have just one connected to the spare TB port on the M1 and have had no problem.

Both are just Amazon low cost hubs (read cheap Chinese stuff) and I have no idea if the problem would develop with a high end name brand box.

Anyway, this is just FYI on a problem that nobody else may see, but if your pride-and-joy Pro XDR fails to start after Ventura, yank out anything plugged into the monitor before reaching for your cardio resuscitator.

A few days after I upgraded to Ventura the same happened to me. In short, the monitor was black and would not respond to anything.
At first, I thought the UPS it was plugged into went bad. However, the UPS was still on and there were other items plugged into it as well. To confirm, I unplugged the monitor and plugged it directly into the wall. I also unplugged it from the back of the monitor. It came back on once I plugged everything in.
Yesterday, the same thing happened. I contacted Apple. Here is what they walked me through:
(1) Hold power button for 10 seconds, release, and push power button. Result - still blank screen.
(2) Same as above, but after pushing the button, hold Command R. This brought the screen back.
(3) Reinstalled Ventura.
The tech said that if it happens again we'll go through the process of getting a new screen.
Hope this helps.

Well, the problem is back and a lot more consistent. Apple wants me to bring the monitor in to the store.
Bummer.

Did they solve this for you?
My XDR went black last week all of a sudden. I have tried everything possible and will bring the XDR to the Genius bar here in Germany. The weird thing is, that the Macbook still draws energy from the display... So weird

It's an unfortunate reality that Apple's monitors now have a lot going on software-side and even though they support firmware upgrades through the connected Mac Apple does not provide any firmware-restore or reset process or even dumping error logs and sending them to Apple for a remote fix. It's absolutely ridiculous that Apple can run remote diagnostics on their Macs, iPads and iPhones for AC+ purposes, connect remotely to troubleshoot Mac issues and when it comes to their monitors it's just a black box that you have to physically transport to a location to get any service whatsoever.

Nobody can convince me that Apple does anything other than plugging in some revival magic that fixes a dozen known black screen bugs within minutes by reflashing iOS on the monitor or whatever it needs to do. With a modern XDR display there is no technician that opens up the back and replaces a blown capacitor, it's all software and could be done entirely remotely.

Not that any other monitor manufacturer is any better, but at least their monitors don't randomly stop working. My non-Apple monitor worked as is from day one for 10 years now without a single update required and worked with half a dozen Macs over the years seamlessly. The only thing that could break would be a capacitor blowing or some other hardware fault.
