Sony revealed this week that it will begin to deliver in mid-to-late January its promised firmware update bringing support for Dolby Vision high dynamic range (HDR) to select Bravia 4K Ultra HD A1E OLED TVs and 4K LED-LCD TVs with full-array LED backlighting and local dimming.

The firmware carrying the Dolby Vision support will arrive in the United States and Canada in the Sony A1E series of 4K OLED TV models, as well as in the Z9D, X940E, and X930E series of full-array LED-LCD TVs sold in the United States and Canada.

After the firmware update arrives, the specified Sony TVs will have the ability to present HDR from three popular profiles, including baseline HDR10, Hybrid Log-Gamma (HLG) and Dolby Vision.

High Dynamic Range is an enhancement that widens the contrast ratio bringing deeper blacks with greater degrees of fine detail and brighter whites with more visible fine detail and color shading. It also adds brighter specular highlights in localized points on the screen, such as bright objects like explosions and candle light.

Dolby Vision is considered a premium HDR format because it uses so-called dynamic metadata that enables grading HDR contrast and color on a scene-by-scene or even frame-by-frame basis, instead of applying uniform grading levels throughout a program or movie.

Dolby Vision is supported in select Ultra HD Blu-ray discs from all Hollywood studios, except 20th Century Fox, so far. However, the proposed acquisition of Fox by Disney could change that.

Streaming titles are offered in Dolby Vision from Vudu, Amazon and Netflix.
