LG said Thursday that a new firmware update for its 4K Ultra HD OLED TVs is bringing support for Dolby TrueHD lossless sound technology to 2017 models.

The update will make it possible for 2017 LG OLED TV owners to listen to lossless, uncompressed 5.1 and 7.1 channel Dolby TrueHD audio soundtracks through their television’s speakers once the firmware update is delivered and installed this month.

The qualifying televisions will have to be setup to accept automatic firmware updates, otherwise users will have to make the update manually.

With the update installed, LG 2017 OLED TV owners also will be able to enjoy Dolby Atmos object-based audio in a lossless container instead of the lossy Dolby Digital Plus container that the televisions were previously equipped to decode.

All of LG’s 2017 OLED TVs have built-in Dolby Atmos sound supported in the B7 and C7 through internal speakers, and in sound bars offered with E7 and G7 models. The top-of-the line W7 “wall paper” TV models will use the TrueHD support with its external Atmos-enabled soundbars that incorporate motorized elevating left and right drivers carrying height-channel support.

Many 4K UHD Blu-ray titles already include Dolby TrueHD lossless audio, LG said, and the 2017 OLED TVs will be able to take advantage of the clearer, brighter high-resolution sound once the firmware update is installed.

The company added that for “maximum benefit” of Dolby TrueHD, the bitstream can be “streamed through a compatible sound bar to the TV.” Of course, the TrueHD soundtracks from supporting external devices can also be supported by connecting the playback device to a Dolby TrueHD supporting AV receiver with discrete 5.1- or 7.1-channel speaker setups.

In addition, LG’s 2017 premium OLED TVs support Dolby Vision high dynamic range (HDR), as well as basic HDR10, Hybrid Log Gamma (an HDR profile expected to be used in future cable, satellite and possibly over-the-air TV broadcasts), and through another recent addition, Technicolor picture mode that offers fine tuning adjustments of the TVs picture quality as determined by the Hollywood technical production house.

“LG’s OLED TVs have become the de facto leader in the premium TV market and is the optimal platform for those seeking to experience content the way its original creators envisioned,” stated Brian Kwon, LG Electronics Home Entertainment president. “With Dolby’s audio and visual technologies, LG continues to deliver an enhanced experience that pushes the boundaries of home TV viewing.”
