How To Identify HDMI 2.1 Cable

HDMI 2.1 cables can be challenging to spot. They have the same design as older HDMI cables, except instead of 1.4 or 1.2, they may feature a 2.1 designation on the box. They function similarly to older HDMI cables; however, they can sometimes deliver a slightly better picture. This is accomplished by using a different style of cable structure, higher-quality materials, and more stringent testing criteria.

Identifying HDMI 2.1 cables can be complex since many older cables compatible with earlier versions of the standard are still being sold as 2.1 cables. The easiest way to identify a 2.1 cable is to look for the 2.1 or 2.1a designation on the cable. Cables marked 2.0 will not work with 2.1 ports and vice versa.

  1.  Standard
  2.  Enhanced
  3.  Power Delivery.

Standard HDMI 2.1:

Specification for HDMI® 2.1a. HDMI® Specification 2.1a is the most current update to the HDMI® specification.

Do HDMI 2.1 cables look different?

At first glance, HDMI 2.1 and HDMI 2.0 don’t appear to be that dissimilar; in fact, certain HDMI 2.0 TVs and displays can pass as HDMI 2.1 devices.

As far as the physical characteristics, the 2.1 model cables match up to 2.0. The only real difference that you may notice is the color of the connectors. HDMI 2.1 HDMI connectors are gold-colored, just like the HDMI 1.4 connectors.

In that case, you must ensure that the HDMI 2.1 cable you are using is certified and labeled as such, as many HDMI 2.0 cables are unidentifiable and may be misidentified as HDMI 2.1. This is especially true of HDMI cables used in computers; in this case, there is no way to identify if the HDMI is 2.1 positively.
