My Mac mini is only allowing a refresh rate of 144 Hz, rather than 240 Hz

I recently purchased a Mac mini with an M4 chip and connected it to my monitor using a HDMI 2.1 cable. However, the Mac mini is only allowing a resolution of 2560 x 1440 at a refresh rate of 144 Hz, rather than the 240 Hz I had expected. Is there a way to resolve this issue? Do I need to use a Thunderbolt 4 cable instead? My monitor does have a Thunderbolt 4 port, so I’m not sure if that’s the solution.

Okay, I’ll give that a try. It’s strange that it won’t support 240Hz refresh rate. The HDMI cable I have is “Ultra Cable Certified.” I’ve tried both HDMI ports on my monitor, and yes, I’ve verified that it’s a genuine certification.

That info is needed to provide the optimal connection method.

or... a short 3' high speed 8K TB/USB-C to DisplayPort cable.
