Mac Mini M1 HDMI output

Hello there!


I hope everyone is fine!


Recently I bought a Mac Mini M1. I have a LG 27GN880 which is capable to display 2560x1440 at 144hz. After I setup the Mac with the monitor I realized that the display runs at 100hz max. I thought all right maybe I need another HDMI cable. I bought one, there's no improvement.

I have an USB-C to DisplayPort cable as well, it can deliver 144hz.

According to the specs I don't know why the HDMI can't work at 144hz.

Can anyone please help me with this?


Thank you for advance!

I’m surprised that you are getting over 60Hz using HDMI.

see “Video Support” at > Mac mini - Technical Specifications - Apple


also see > Connect a display to Mac mini - Apple Support


Personally I would use the USB-C to DisplayPort cable.

I use USB-C to DisplayPort to get the desired result. I just wish to use the HDMI to save the USB-C port for something else.

I saw the specs a couple of times. I understand that HDMI version is 2.0. According to my research this version is capable to display 2560x1440 at 144hz.

I am not sure what I am missing. There is a chance for I misunderstood something.
