MacOS Ventura has broken USBC - Display port Cinema Display monitors again??

After hours with Apple Support and getting my ticket escalated I'm still experiencing the same issue or next steps from Apple on how they plan to resolve this.

• Reinstalled OS
• Booted in Safe Mode *this did resolve the issue temporarily (in Safe Mode), but next step was to create a new account to see if startup apps were causing the issue but the issue still existed with a fresh account.
• Tested all Disks
• Updated monitor firmware (needed to use a colleagues computer who hadn't updated to Ventura in order to do this)

Again, the workaround I've found is to use an HDMI which is less convenient, lower resolution, requires a dongle, and forces me to also plug in my charger.

Same thing happened to my Dell 49' curved monitor as soon as I updated. I would always plugin with the USB type C and it's now unusable. The only workaround I've found is to use an HDMI and old dongle which also requires me to plug in my Macbook charger since I was previously able to charge with the same USB type C that was also connecting to my monitor... Resolution for HDMI has decreased and I now have a mess of cords everywhere...

Buying a new monitor is unacceptable and it clearly isn't related to the age of the monitor.

I have the same issue. I just upgraded the system software on my Mac Book Pro to Ventura and now the graphics on my 24" cinema display are shaking. Does this mean there is no fix? They must have had system updates following Big Sur because my MacBook Pro to Cinema Display has been working fine up until this point (mini display port adaptor and USB C adaptor).

I really cant afford to get rid of the display. And it is environmentally irresponsible to make us throw them out to buy new ones.

apple supports solution … buy a new monitor. 😡😡

This is in fact not a solution. As others here mentioned they have relatively new monitors, and I do as well. The USB connection does not work. My panel is 5K via DisplayPort, but maxes out at 4K via HDMI. The "HDMI workaround" doesn't work for me.

This is so incredibly frustrating – I also contacted Apple support and had the ticket escalated and they just stopped contacting me. I had to update to Ventura on my work Macbook and I'm getting max 1080p through DisplayPort/ USB Type-C. This isn't an issue on my personal Macbook that I kept on Monterey. I understand they rewrote a lot of these drivers, but how long until they realize that their DisplayPort driver is completely broken?

Works for me: MacMini9,1 and MacBookPro11,3 on a Cinema HD 30.

(In case you're wondering: the MacBookPro11,3 does indeed run Ventura, thanks to OCLP)

Same problem, now my apple cinema is sitting collecting dust

I'm having the same issue. At times it works after an endless combination of restarts, changing up the order of inputting the cables to the screen/docking/mac etc.

Apple - fix this please!
