8K TV gets an official definition and logo

8K TV gets an official definition and logo

Samsung has introduced several 8K TV models at CES this year. (Image: Samsung.)

8K TVs are now selling, but what else must they’ve besides their 7,680 x 4,320-pixel resolution before manufacturers can slap an ’8K Ultra HD’ badge on them?

Well, CTA (Consumer Technology Association) and its member companies has finally announced the official industry display definition for 8K UHD televisions. And manufacturers are supposed to adhere to the criteria set out in this definition for their 2020 models before they can slap the new ‘8K Ultra HD’ logo on them.

In a nutshell, CTA says an 8K UHD TV must have:

  1. At least 33 million active pixels (7,680 x 4,320) within a 16:9 viewable window.

  2. At least one HDMI input that supports this 8K resolution. It must also supports a bit depth of at least 10 bits; frame rates of 24, 30 and 60 fps; HDR transfer functions and colourimetry as specified by ITU-R BT.2100; and HDCP 2.2 or equivalent content protection.

  3. An up-conversion function to upscale non–8K content (even SD) to the 8K resolution.

  4. The ability to not just accept or receive 10-bit 8K images, but also the ability to reflect changes to any of the 10 bits on the rendered image.

Look out for this logo on 8K TVs in stores in 2020. (Image: CTA.)

Finally, the CTA 8K Ultra HD logo license and certification agreement will be available in the coming weeks, but the logo may only be used from Jan 1, 2020. This logo licensing program is voluntary though, which means like the CTA 4K Ultra HD logo, there may be TVs that meet the definition but do not use the logo. That said, CTA has a ton of members, including major TV makers such as Samsung and LG, so I expect these brands to fully make use of this logo to differentiate their sets from the rest.
