Communication bandwidth will be affixed to the cable to distinguish the transcendentally confusing DisplayPort version

The

Video Electronics Standards Association (VESA), an industry standards body for video peripherals, has announced a certification program that makes it easier to understand the 'actually supported data transfer speeds' for various devices labeled DisplayPort 2.0.

VESA's newly announced certification program aims to clarify the status of compliance with the 'Ultra-high Bit Rate (UHBR)' specification for the data transfer rate of DisplayPort 2.0. DisplayPort 2.0 has multiple specifications depending on the data transfer speed, and even with the same 'DisplayPort 2.0 compatible' cable, the data transfer speed may differ depending on the internal specifications not specified.

Below is a sample label issued by this certification program. The cable labeled 'DP40' has 4 lanes of UHBR10 to indicate that it supports data transfer speeds up to 10Gbps, and the cable labeled 'DP80' has a data transfer rate of up to 20Gbps. It shows that it has 4 lanes of UHBR20 which shows that it corresponds to.

VESA announced this certification program on February 28, 2022, but prior to this announcement, several products were certified and reviewed by multiple video sources and display products. 'Soon, certified products will be on the market,' he said, revealing that a cable with a full-size improved DisplayPort and Mini DisplayPort connector has passed the DP40 and DP80 certification reviews. Is spelled out.

VESA representative Craig Willy told the press that the certification program was designed with the confusion caused by HDMI 2.1 in mind. The following article explains in detail what kind of confusion the word 'HDMI 2.1 compatible' has caused.
