Buy a 4K TV for Christmas? Bet it wasn’t a new “UHD Premium” set
 

The UHD Alliance (UHDA), a who's who of the TV and movie industries, has unveiled Ultra HD Premium, a new standard for UHD (4K) TVs that arrives just in time for everyone to regret picking up a new 4K TV for Christmas.

While the core resolution of UHD remains unchanged at 3840×2160 pixels, any device bearing the UHD Premium logo will have to meet minimum specs for high dynamic range (HDR), peak luminance, black levels, and wide colour gamut, among others (full specs below). Effectively, the UHD Premium logo guarantees that the TV, device (such as a UHD Blu-ray player), or content fully supports HDR, and will work with UHD streaming services from the likes of Netflix and Amazon.
