I bought the acer gn246hl (a 144hz monitor) and everything says it is 60hz. I checked the windows display options, I checked nvidia display options, I even tried using a custom resolution on the nvidia options and it told me my monitor wasn't suited for 1920x1080 at 144hz. I have an rtx 2060, i have it plugged into a displayport to dvi dual link. I checked the monitor settings and it said the input of the signal wasa at 60hz. No idea what to do, please help.
