New UHD standards make buying a TV easier

Formed in January 2015, the UHD Alliance (UHDA) set out to define what exactly Ultra HD is and prevent a jumble of standards and formats. This week the UHDA revealed the standards against which so-called Ultra HD displays will be graded against.

Displays that meet the criteria which the UHDA has set forth will be emblazoned with a trademarked, “Ultra HD Premium” logo which will let consumers know that a display meets the UHDA’s standards and is actually an UHD display.

“The ULTRA HD PREMIUM logo gives consumers a single, identifying mark to seek out so they can purchase with confidence”, UHDA President, Hanno Basse said in a statement.

This standard could solve the UHD vs 4K resolution confusion that currently plagues consumers but resolution is not the only factor the UHDA will be taking into consideration. For a display to be given a Ultra HD Premium sticker it will need to meet or exceed these minimum requirements:

Image Resolution 3840×2160

Colour Bit Depth 10-bit signal

Colour Palette Wide Colour Gamut

Signal Input BT.2020 colour representation

Display Reproduction More than 90% of P3 colours

High Dynamic Range

  • SMPTE ST2084 EOTF
  • More than 1000 nits peak brightness and less than 0.05 nits black level or 540 nits peak brightness and less than 0.0005 nits black level.

What this means in simple terms is that how colours transition from one to another, how the display receives a signal from a set-top box, decoder or a DVD player and even how dark the blacks are will be taken into account when grading a display.

The process of classification has begun and earlier this week at CES 2016, LG revealed its OLED 4K displays and said that the products exceed the specifications brought forward by the UHDA.

Hopefully the end result will be that buying a UHD television, monitor or display is safer and that the disappointment of buying an HD Ready TV instead of a Full HD TV doesn’t have to happen ever again.
