Monitor can’t reach 144hz

[rileyoboyle32]

My 144hz monitor can only reach 120hz. I’m connecting the monitor to my pc with a dvi d cable and i can only get 120hz. Also i have Radeon RX 580 graphics card

Most monitors that have a sync mode that allows more than 120Hz require you to use Displayport. if you're using HDMI or DVI, you won't get that performance.

Which monitor and resolution? Dvi-d can only manage 144Hz in 1080p. For 1440p 144Hz a Displayport cable is required. Dvi-d 120Hz at 1440p may be possible with some monitors.
