Usage notes
The Consumer Electronics Association defined "Ultra High-Definition" in 2012, and the ITU's Rec. 2020 standard specifies a wider color range for UHD video. The UHD Alliance's "Ultra HD Premium" logo, introduced in 2016, certifies TVs for resolution, brightness and HDR performance. UHD Blu-ray discs hold up to 100 GB.
