Ultra HD Blu-ray (4K Ultra HD, UHD-BD, or 4K Blu-ray) is a digital optical disc data storage format that is an enhanced variant of Blu-ray. Ultra HD Blu-ray supports 4K UHD (3840 × 2160 pixel resolution) video at frame rates up to 60 progressive frames per second, encoded using High Efficiency Video Coding. These discs are incompatible with existing standard Blu-ray players.
The first Ultra HD Blu-ray Discs were officially released in the United States on February 14, 2016. To differentiate retail Ultra HD Blu-ray releases, the format usually uses a black opaque or largely transparent keep case packaging format (as opposed to blue), but with the same case size as standard Blu-ray. The format is supported on Microsoft's Xbox One X, One S, Series X, and Sony's PlayStation 5. Software made for the PlayStation 5 can use 100 GB UHD Blu-ray discs.
