The VG2756-4K (via USB-C) by default can display 4K 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 4K 30Hz.
There's not enough bandwidth for USB 3.2 speeds when connected via USB-C to output 4K 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.
