Hello!

I have two U3219Q monitors conected to Mac Mini using USB Type-C. I am using macOS 12 Montery and both screens worked. I updated the firmware on one U3219Q (disconected the other U3219Q first). Now the updated U3219Q wont work with USB Type-C. It works if I use HDMI to the updated U3219Q and USB Type-C to the not updated U3219Q. If I connect the updated U3219Q to my laptop using macOS 11 Big Sur, the USB Type-C works.
