The first batch of HDMI 2.1 48G branded cables was announced at the end of 2018, but they have not been formally certified by the HDMI Forum. One of the reasons is that the HDMI 2.1 certification plan is not yet ready. Now the certification of these products is also coming, marked as Ultra High Speed HDMI (Ultra High Speed HDMI). In addition, TV manufacturers are preparing the first batch of ultra-high-definition TVs using HDMI 2.1.

Since the HDMI 2.1 48G cable and the signal source and receiver are physically different from the existing HDMI 1.4/2.0 cables, product manufacturers must adopt new manufacturing methods, and the HDMI Forum must introduce a new certification program, which includes A compliance test to ensure that it works properly at high data rates and supports all functions.

The HDMI Forum admits that cable manufacturers usually have enough experience to build HDMI 2.1 48G products. However, since the HDMI 2.1 48G certification program has not been completed, it is not recommended that they sell products marked with ultra-high-speed HDMI cables.

The HDMI 2.1 48G cable uses 4 data channels, each of which runs at a speed of 12 Gbps, with a total bandwidth of 48 Gbps, which is higher than the current 18 Gbps, while retaining backward compatibility with existing equipment. The additional bandwidth provided by HDMI 2.1 enables it to support new Ultra HD resolutions and refresh rates, including 4Kp/120Hz, 8Kp/100 or 120Hz, 10Kp/100 or 120Hz, and supports upcoming color spaces such as BT.2020( Rec. 2020), 10/12/16 bit color depth. The HDMI Forum plans to launch its UHS HDMI interconnect certification program in the next few months. In the future, “official” HDMI 48G copper and optical cables will be available
