Mac Mini M4 Not Supporting 240Hz on 1440p Monitor

Hey everyone,


I recently got my hands on a Mac Mini M4 (base model) and I’m trying to set it up with my MPG ARTYMIS 273CQRX-QD monitor. This monitor can support 240Hz at 1440p, but I’m having some trouble getting it to work.


I bought an Ultra Cable certified HDMI cable, but when I connect my Mac Mini to the monitor, I can only choose a refresh rate of 144Hz at 1440p. I know the monitor can handle 240Hz, (you can check) so I’m not sure what’s going on.


I’ve checked the QR code on the Ultra Cable and it’s real, so I’m not sure if there’s something wrong with the cable or the monitor.


Any tips or advice would be super helpful!

Mac mini, macOS 15.2
