Hdmi Forum Announces Cable Certification Program for HDMI 2.1

The HDMI Forum has announced a certification program for cables required for HDMI 2.1. The organization does this partly because new cables are required to use the HDMI 2.1 standard.

The certification program is mandatory for all ‘Ultra High Speed’ cables, writes the HDMI Forum. The organization wants to achieve that high-quality cables that support 4k and 8k videos, VRR, eARC and all other HDMI 2.1 functions. During the program, the cables will also be tested to ensure they meet the requirements to minimize electromagnetic interference. Once certified, manufacturers of the approved cables must add an Ultra High Speed ​​HDMI Certification Label to the product, including watermark and QR code.

An Ultra High Speed ​​HDMI cable is required to make full use of HDMI 2.1. This is related to the fact that hdmi 2.1 uses a new signal technology, called Fixed Rate Link. FRL is required to enable the higher bandwidths of up to 48Gbit/s. This higher bandwidth makes it possible for televisions, for example, to receive 8k material with 60fps or 4k images in combination with 120fps via HDMI. HDMI 2.0 uses another signal technology called Transition Minimized Differential Signaling, which is also used in the DVI standard.
