Bandwidth limitations on USB 3.2 will not allow USB-C to output 4K at 60Hz.

 

If users connect via DP or HDMI, USB 3.2 speeds will not be affected.

VG2756-4K (via USB-C) by default can display 4K 60Hz when the OSD setting for "USB 3.2" is Off


If "USB 3.2" is On, then a USB-C connection can only display 4K 30Hz.
