Sony goes super-size with its first 8K Z9G (ZG9) TVs

08 Jan 2019 | Torben Rasmussen |

At CES 2019, Sony has unveiled its first 8K TVs in the form of the super-sized 85- and 98-inch Z9G (ZG9). The ’Master’ series TVs feature full array local dimming, Dolby Vision, Dolby Atmos, and IMAX Enhanced.

Sony’s first 8K TVs

Sony is joining the 8K movement with Z9G in the US and ZG9 in Europe. 8K comprises over 33 million pixels, which is four times as many as 4K. TVs also include the Japanese company’s latest LCD technologies, some of which has been developed specifically for the ZG9 series, the company said.

- ”Completely new dedicated 8K technologies have been developed for the ZG9 series, including Backlight Master Drive with full-array local dimming and 8K X-tended Dynamic Range PRO. The Backlight Master Drive on the ZG9 has ultra-dense LED modules which are independently controlled, delivering unprecedented contrast with punchy brightness and pitch blacks. To leverage the most out of this backlight system, 8K X-tended Dynamic Range PRO uses the saved energy to intelligently boost the brightness in the areas where it needs to be boosted,” Sony explained.

The super-sized Z9G 8K TVs are part of Sony’s ’Master’ series that was introduced in the second half of 2018. The company says that the TVs have been designed to respect the creator’s intent. The initiative also covers an ’IMAX Enhanced’ mode and a ’Netflix Calibrated Mode’.

The LCD TVs also offer some of the technologies that were introduced with high-end 2018 TVs. The ’X-Wide Angle’ uses a special combination of filter and optics to improve viewing angles, while ’X-Motion Clarity’ can improve motion clarity by applying black frame insertion techniques in the individual dimming zones.

Sony claims that the 8K TVs can deliver ”20 times the contrast of conventional LED TVs” but refrains from commenting specifically on peak brightness. However, Sony’s wording suggests that these TVs will be able to hit quite high levels. In the past, Sony TVs with +1000 nits peak brightness have been promoted with “6 times the contrast of conventional LED TVs”. So, are we talking 4000 nits here? We hope to learn more soon.

The 8K TVs support HDR10, HLG, and Dolby Vision but Sony continues to disregard Samsung’s HDR10+ format, arguing that it can achieve the same result with HDR tone-mapping.

Like Samsung, Sony has implemented an 8K upscaler that can enhance images in real-time. The company explained that it is using a database with 8K reference material to determine the upscaling approach for that particular scene and that the processor can ”detect and analyze each object in the picture”.

Upscaling is required to present full-screen images on any 8K TV but manufacturers also like to emphasize the systems due to the dearth of 8K content. The UHD Blu-ray format is currently limited to 4K resolution and streaming providers such as Amazon and Netflix have yet to announce plans for 8K streaming.

So what about HDMI 2.1? Sony did not comment on improved bandwidth or HDMI 2.1 features such as VRR or eARC. Some of Sony’s previous TVs already support eARC so it would be surprising if this was not included in these 8K TVs but the more important matter is of course improved bandwidth to allow for 8K video input. FlatpanelsHD is chasing answers at CES.

Dolby Vision + Dolby Atmos

Dolby Vision was already implemented in high-end Sony TVs so it is no surprise to see it return in Z9G. Later this year, Sony will add Dolby Atmos support to the mix via a firmware update. Atmos support has been announced for select 2019 Sony TVs.

For the full Dolby Atmos experience you need additional speakers but Sony has also made it a priority to improve built-in sound.

- ”To deliver the Sound-from-Picture Reality experience, the new Acoustic Multi-Audio on the ZG9 utilises four front-facing speakers; two on the bottom and two on the top – to deliver a faithful sound position. Viewers will hear the sound coming from the screen, and not where the speaker is located. In addition, the ZG9 has a TV Centre Speaker Mode for those who have a home cinema setup – the TV becomes the centre speaker.”

There is no mention of DTS:X support, which is a little curious considering that ‘IMAX Enhanced’ that is now supported was created by IMAX and DTS.
Like new TVs from Samsung and LG, select Sony’s 8K TVs will support Apple Airplay 2 and HomeKit.

- ”Sony Android TVs will be compatible with Apple AirPlay 2 and HomeKit. AirPlay 2 lets you effortlessly stream content from your iPhone, iPad and Mac right to your Sony TV,” the company said. ”TVs can be added to the Home app and included in scenes or automations with other HomeKit accessories. For example, users can create a “Movie Night” scene in the Home app to easily turn on their smart TV and dim the lights, and simply ask Siri to launch the scene.”

Lastly, the TVs come with version 8 (Oreo) of the Android TV operating system built-in as well as Google Assistant and Chromecast. Sony is furthermore highlighting a new “slimmer, more rounded” remote control and a new processor for “quicker response of launching apps, powering on the TV, and more”.

Sony Z9G in the US and ZG9 in Europe will launch later this year. Exact availability and pricing details were not announced. The TVs will be showcased for the first time at CES 2019 so stay tuned for our hands-on impressions.
