UHBR (Ultra High Bit Rate)
The DisplayPort 2.x link rates above HBR3.
UHBR is the family of DisplayPort 2.x link rates — UHBR10, UHBR13.5, and UHBR20 — that raise per-lane bandwidth well above the older HBR3 rate, enabling higher-resolution and higher-refresh displays over a USB-C connection. Reaching a UHBR rate requires the source, the cable, and the display to all support it; any weak link caps the result.
