I am hoping somebody may help. I am attempting to get my Macbook Air M2 working at 3840×2160@60Hz with my new to me Sharp PN-K321. I can get 3840×2160, however solely at 30Hz.

Issues I’ve tried:

  • 2 totally different model usbc to displayport cables from amazon, each
    marketed as supporting 4K@60hz

  • a usbc to HDMI cable marketed as supporting 4K@60Hz

  • In monitor menu switching dipsplayport mode to MST: this simply gave me
    1920×1080@60Hz

  • Reset monitor to manufacturing facility settings

I do not actually know the place to go from right here, any recommendation?
