the vg2755-2k/vg2455-2k (via usb-c) by default can display 2k 60hz, and the osd setting for "usb 3.2" is off.
if the user turns "usb 3.2" on, then a usb-c connection can only display 2k 30hz.
there's not enough bandwidth for usb 3.2 speeds when connected via usb-c to output 2k 60hz.
this situation will only happen on a usb-c connection. if users connect via dp or hdmi, usb 3.2 speeds will not be affected.
