DisplayPort
DisplayPort limits depend on the number of lanes and the link rate:
- Reduced Bit Rate (RBR) and High Bit Rate (HBR) are supported by all versions of DisplayPort.
- High Bit Rate 2 (HBR2) is supported by DisplayPort 1.2 and newer.
- High Bit Rate 3 (HBR3) is supported by DisplayPort 1.3 and newer.
