This monitor is supposed to work up to 165Hz, but whenever I select 144 or 165 I get flickering and it shows black the lower 25% of the screen (see attached pic). 120Hz works fine.

At first I thought it was my cheap HDMI cable, but I purchased a new USBC-DisplayPort and I get the exact same results. I'm using a Mac mini 2023.

Any ideas? Thanks in advance.
