The M1 Macs use Apple's own implementation of Thunderbolt and that could be the cause. If so, maybe they will fix it in the M2 - but in this case, I now have a $5,000 paperweight and need to fork over cash for a M2 laptop ...

I really, really nobody is silly enough to do that, but I suspect they will be. Things kinda worked under Monterey, but worked far, far more poorly under the hyper-buggy, awful Ventura.

This should tell everyone that it is a pure software issue and being bullied/misled into buying a new computer is borderline fraudulent behaviour.

It's just a question of Apple's incompetent software developers making very buggy, poor drivers for the M1 in Monterey, and then somehow, astonishingly, managing to make it even worse under Ventura. For Intel chipsets, base drivers were most likely supplied by Intel themselves (chipset vendors usually provide such things) but the quality of vendor drivers is often poor; Apple may have replaced or debugged them, perhaps, but there are years of Intel chipsets to examine for history and to see all the places where numerous USB device quirks were accounted for.

This is Apple's fault, it's Apple's software, don't buy a new computer EVER for that - complain to Apple until they fix their broken product - or it's not fit for purpose / if you went from Monterey to Ventura, then they broke your computer - either way they should refund you (sucks if your country has weak consumer laws that don't allow that though).
 
[Description of the errors I'm seeing with external monitor support]
How many monitors do you have? I have similar behavior with 3 or more monitors. Dual display is fine is okay though.
Just one external. This is an M2 Air; no more are supported (aside from DisplayLink).

On the other hand, all this did work to a degree under MacOS 12 - it was MacOS 13 that made everything worse. So really hoping that there's a software fix possible

I find the symptoms can be reduced (but not eliminated) by not having the laptop sleep so easily and also by changing  > System Settings > Privacy & Security > "Allow accessories to connect" to "Always"
I dont have that option, is only for laptops? (Im on a Mac Studio)

Gotcha. I have an M1 Max connected to a TS4 dock and with dual 1440p displays I have no issues at all. Mac wakes from sleep and the displays light up no problem.
 
Did I say it invalidates anything? The person I quoted made it seem like no one is running an external monitor without issues.
You don't have to explicitly say it but your post implied that it did. You quoted my post and made it seem like I am the ONLY one running an external monitor and having issues. That's why antibolo corrected you.

Just search for "ventura usb-c display problem" on discussions.apple.com and you'll see what I mean. My friend's company has stopped all their users with Apple silicon from upgrading to Ventura because of this. I'd say that's properly described as a mess.

Guess i’m lucky. This is actually the first i’ve heard of this issue.

Yeah that is what is incredibly frustrating - it affects a non-trivial number of people but it doesn't affect everyone and there's yet no discernible pattern i.e. Mac Studio works for some and not for others. Or LG 4K monitors and CalDigit docks work for some and not for others

This is the first time I've ever seen a problem where I need to reboot the Mac at least once a day :eek: - that is the exact opposite of my experience with Macs till now - and I've used almost every Mac since the G3

Other users are mentioning that 'Apple is aware of this issue' - (I've definitely put it into Feedback Assistant every chance I get) that's why was hoping to see any improvements in 13.2 and 13.3.

FWIW I have a Dell U2720Q connected via thunderbolt.
