Most Sony 4K TVs Are Getting a Hybrid Log Gamma HDR Update
Stephan Jukic – February 4, 2017
Sony has formally confirmed that its 2016 and 2017 4K HDR TVs will be getting a firmware update that’s going to bring them HLG (Hybrid Log Gamma) HDR support as a future-proofing measure for new, mainly broadcast, HLG HDR content that’s expected to emerge in 2017 or 2018. Up until the new name brand TV releases of early 2017, only a very small selection of 4K televisions in some markets offered support for HLG. Now, in addition to Sony, brands like LG are also updating their 2017 and possibly 2016 4K HDR TV models for the new high dynamic range standard.
As for HLG itself, to clarify a bit what it means, the Hybrid Log Gamma standard is a new type of HDR technology which was developed jointly between the BBC and Japanese state media broadcaster NHK for the sake of delivering high dynamic range video in 4K resolution through over-the-air and other broadcast distribution channels. In contrast to HDR10 or Dolby Vision HDR standards, HLG doesn’t require specific hardware updates to existing technology and is much easier to insert into broadcast video sources than these other standards.
Of course, it’s worth noting that at the current time, pretty much no HLG video consumer video content to speak of exists anywhere yet outside a couple of very limited public experiments from the BBC and others. In other words, the fact that Sony or anyone else’s HDR televisions come with HLG has pretty much zero immediate relevance to you as a consumer, sitting in your home and trying to enjoy the high dynamic range benefits of your particular TV from these brands (if you own one).
Nonetheless, being ready for the 4K HDR future of content is never too bad and the fact that the HLG update costs nothing extra is a further benefit for people who already own or want to buy one of Sony’s excellent 2016 and 2017 4K HDR TVs.
Sony’s 2017 4K TV lineup consists of the company’s new flagship OLED 4K HDR TV model, the Bravia A1E. Following this are the stunning Z9D ultra-premium LCD HDR models, which were actually released in late 2016 but which can be considered 2017 TVs due to their sheer performance specs. And then, there are Sony’s 2017 replacements to the 2015 and 2016 XBR C and E TVs. These are the new XBR-E models which include the X-940E and X930-E.
All of Sony’s 2017 4K TVs also come with support for both HDR10 and Dolby Vision HDR technology. In contrast, the 2015 and 2016 HDR models from the brand only supported HDR10.
