The Mac Mini works fine with the monitor when it is not in DP 1.2 (HBR) mode. I.e. Only 30Hz at UHD resolution. When DP 1.2 mode is turned on the monitor shows "No Signal" and it goes into sleep mode. I am using a usb-c to DisplayPort cable: https://www.amazon.ca/gp/product/B01J6DT070.
I would like to hear from anyone who successfully made this combination work and what cable was used.
Thanks.
Mac mini, macOS 11.5
Is DP1.2 enabled on the monitor?

Hi. The issue occurs when DP 1.2 is on. No issue when it is off.
Looks like it’s not working on the Dell. You’ll need to contact them. Good luck!
