Mac – Getting 5120 X 1440 @ 120Hz on a 2018 Mac mini

displaydisplayportmac-minithunderbolt

I recently just purchased a Samsung CRG9, which is a really great monitor. Only problem I have is that I’m not able to get the full 5120 X 1440 at 120Hz that the monitor is rated for. I can get the 5120 X 1440 at 60Hz just fine, but it would be nice to be able to get 120Hz at that resolution as well if possible. I’m using a high-quality DisplayPort 1.4 to Thunderbolt 3 Cable.

Does anyone here know how to do this? Especially if you own this monitor.

Thanks in advance!

According to EveryMac, [The 2018 Mac Mini] 'supports "up to" three displays. It can support either (1) two displays up to 4096x2304 at 60 Hz via Thunderbolt 3 and one display up to 4096x2160 at 60 Hz via HDMI 2.0; OR (2) one display up to 5120x2880 at 60 Hz via Thunderbolt 3 and one display up to 4096x2160 at 60 Hz via HDMI 2.0.'
