This section describes the specifications of the external and internal DP connectors. Updated in DP v2.1.
DP Connector Types

External mDP Connectors apply to both legacy and enhanced mDP connector types.
Enhanced mDP Connectors, only changes in the mandates and designs are provided.
Note: Enhanced versions are referred to by “enhanced” or “Enh”. Non-enhanced versions are referred to as either “legacy” or by no special terminology, such as simply “DP” or “mDP”.
VESA recommends informative marking for Enhanced DP receptacle connectors for inventory control and for easier identification by platform implementors. The enhanced mDP receptacle is to be marked as “Enh mDP”. The enhanced full-size DP Type-1 receptacle is to be
marked as “UHBR13.5 Type1”. The enhanced full-size DP Type-2 receptacle is to be marked as “UHBR20 Type2”. The marking can be printed, inked, or etched, which is up to the connector vendors. The name of the connector vendor can also be listed, which is also up to the connector vendors.
Enhanced DP Type 1 connectors support up to 13.5 Gbps/lane (UHBR13.5). Enhanced DP Type 2 connectors support up to 20 Gbps/lane (UHBR20). Enhanced FSDP connectors are fully plug/receptacle mating backward-compatible with the legacy versions of the same connectors.
For UHBR10 capability, Enhanced FSDP connectors mandate use of a DP40 –or– DP80 cable. For UHBR13.5 and UHBR20 capability, Enhanced FSDP connectors mandate use of a DP80 cable.
Note: The legacy FSDP footprint will not support an enhanced FSDP receptacle; however, the enhanced FSDP footprint will support a legacy FSDP receptacle

Enhanced Type 1 | N/A | Okay up to 4-lane 13.5 Gbps/lane (UHBR13.5) |

Enhanced Type 2 | N/A | N/A | Okay up to 4-lane 20 Gbps/lane (UHBR20) |
FSDP connector-related information that is not provided within this section.
To enable the full link-rate capability, the design and manufacture of enhanced FSDP devices requires higher precision than what may have been used for the legacy FSDP component designs. For example, details such as the plastic’s dielectric properties, and even the angle of the pins can affect the design operation. All designs should be fully simulated and then sampled across manufacturing batches to verify their final design and manufacturing accuracy.
Additional suggestions are provided in some sections that may be of use in such design work.
Enhanced mDP connectors support up to 20 Gbps/lane (UHBR20) when used with a DP80 cable and up to 10 Gbps/lane (UHBR10) when used with a DP40 cable. Enhanced mDP connectors are fully plug/receptacle mating backward-compatible with the legacy versions of the same connectors.
Note: The legacy mDP footprint will not support an enhanced mDP receptacle, and the enhanced mDP footprint will not support a legacy mDP receptacle
