At the end of November 2017, the HDMI 2.1 standard was officially released. Now more than three years have passed, and related equipment is constantly emerging. Of course, they are all high-end products. You cannot expect them to spread to the mass market.

Today, the HDMI Forum officially announced the launch of a new "Ultra High Speed HDMI 2.1 Cables" (Ultra High Speed HDMI 2.1 Cables) mandatory certification program, which can fully support all the features of HDMI 2.1 and output all functions from the source device to the display . 

This includes: 4K120Hz/8K60Hz lossless video, dynamic HDR, eARC (audio return channel), VRR (variable refresh rate), QMS (fast media switching), QFT (fast frame transfer), ALLM (automatic low latency mode), and many more.

In fact, this kind of ultra-high-speed data cable was designed when HDMI 2.1 was announced, but it has been waiting for more than three years before it finally becomes a reality.

Compulsory certification of ultra-high-speed HDMI data cables includes tests that meet current EMI electromagnetic radiation requirements and minimize wireless interference. Any length of data cable must pass the HDMI ATC (Authorized Test Center) certification test to obtain certification.

The certified ultra-high-speed HDMI data cable will be marked with the product name, certification label, holographic image and two-dimensional code on the packaging box and cable. Use the special HDMI data cable certification APP to scan to obtain product information and verify the authenticity.

At present, more than 140 data line manufacturers have participated in the HDMI Advanced Certification Program.
