8KA Association has updated the 8K TV certification rules

 

The 8K Association (8KA), a cross-industry group promoting the 8K ecosystem, has published an updated specification that follows 8K Association Certified… The specification adds new decoding requirements, new image quality metrics and game mode.

The association is confident that buyers will benefit from the more comprehensive requirements for 8K TVs that are already on the market. To date, 8KA has certified more than 80 TV models.

One of the innovations added to the specification is the Ambient Contrast Ratio (ACR) test, which tests how a TV is capable of delivering high quality pictures in a variety of ambient lighting conditions. For example, when the room is dark, the TV provides high brightness and contrast. But as the ambient light level rises, both of these components of image quality decrease. This can be avoided by increasing the brightness and using a screen with a lower reflectivity. The 8KA ACR test measures the reflectivity of a TV screen in both low and high light conditions. Note that the ACR test is included in the V2.1.0 specification but is not required yet.

The revised specification also adds new game mode requirements, including support for Auto Low Latency Mode (ALLM) and Variable Refresh Rate (VRR) over HDMI 2.1.

The specification for the new rules will begin in January 2022.
