These LG OLED & LCD 4K TVs Get Major Firmware Picture & Audio Updates

LG OLED 4K screens offer some of the greatest picture quality in the market and to further increase the overall superior experience of their 2017 TVs, LG is constantly updating the firmware with new features and performance enhancements. This time the company is adding a couple of significant new features to its 2017 OLEDs and select 2017 LCD models.

The first important update introduces a new Technicolor Expert Mode that display colors optimized by Technicolor’s color scientists (who work on the majority of Hollywood’s premium content). Technicolor Expert Mode mainly modifies the color settings with more vivid colors (although many would consider this mode saturated) and can be activated like any other predefined setting from the Picture Settinga Menu. This Technicolor preset is not the same thing as support for Technicolor’s own HDR format feature, which is also supposed to be added to LG’s 2017 OLED TVs eventually.

According to Tony Dustin, senior colorist at Technicolor:

“OLED technology’s true blacks, color saturation and depth ensured that all of us were looking at the same colors, even when we were not physically together. On top of that, we’re excited that LG OLED TVs are readily available on the market for consumers wishing to experience LG OLED TV picture quality, and this gives us confidence that the images we were working on will be accurately represented for audiences at home,

LG HDR Technicolor update

The second major update is labeled 04.70.07 in the US and 04.70.06 in Europe, and it adds support for Dolby Atmos True HD playback over HDMI. Although all of LG’s 2017 OLED support native Dolby Atmos decoding, it was not possible to send Atmos audio out through HDMI to the speakers. The feature only worked with streamed sources supporting Dolby Atmos like Netflix. Now with this update you can play Dolby Atmos in lossless True HD format directly from Blu-rays, where most Dolby Atmos tracks are actually found.

LG Dolby Atmos Update

It was at IFA 2017 where LG announced its intentions to leverage technologies from Dolby and Technicolor, and this month the updates are finally starting to be implemented on a territory by territory basis. Models that will get this updates within the OLED 4K HDR range are LG’s C7, B7, E7 and W7 models, and from the LCD-LED range the  SJ9x, SJ8x, and SJ7x LCD models.models as of October 20th. Oddly, the premium LG OLED G7 model is still pending on the new updates and LG has not yet confirmed whether it will be coming to this pricey, premium OLED model too. We also have no word on any such updates for LG’s 2016 OLED 4K HDR television models at this time.

In addition, LG has stated that support for Advanced HDR by Technicolor is coming later this year to its 2017 OLED models. This is the fourth HDR format to be supported by LG’s 2017 OLED TVs, but no specific dates have been given as of this writing.

    Unfortunately, LG’s latest firmware (4.70.06/07) has broken Dolby processing… and they’ve acknowledged it, but don’t have a timeline for a fix (as of 11/14/17).
    The issue is when changing HDMI input sources from one Dolby programming to another… the user receives picture, but loses sound… and the only quick way to address is by switching to a non-Dolby (i.e. stereo) source… and then returning to the Dolby source HDMI port that the user wants to view.
    This was not an issue on the previous firmware release (3.x.x)… yet LG has pushed the broken firmware out to the public as of early November.
