If you have a(n) (Intel) Mac mini running macOS Monterey, make sure you're fully up-to-date; a recent update FINALLY fixed a long-standing USB-C issue I was having with my Philips 329P9H/27 32in 4K UHD display (https://www.usa.philips.com/c-p/329P9H_27/brilliance-lcd-mon...).

I would not be surprised if this also affects the 2020 (Intel) MacBook Pro as well

The 329P9H/27 is, for all intents and purposes, an AOC-manufactured monitor.
