It has three HDMI-in ports, but these are the older 2.0 (18Gbps) standard. They can they support 4/8K in 100/120Hz. The fourth port is eARC, and we know it is HDMI 2.1.

The new 2.1 standard is important to future-proof the device and allow for more 8K inputs. There are currently no 2.1 input devices nor soundbars with 8K switching.

Wi-Fi is N – now that will not stream even 4K. BT is 4.2.

But Flatpanels review states something puzzling.

First Android TV is not yet updated to support 8K TV. The interface looks soft and not every app works on 8K. For example, it does not decode 8K HEVC or VP9-2 (8K YouTube).

Sony has built a custom solution with an external video player that can decode 8K video, output it via 4x HDMI 2.0 ports to another box that couples these four feeds together into an HDMI 2.1 output that is then passed to the 8K TV.


Expect to see 500-1000W per hour or a cost of 25-50 cents per hour.

The unit 1,913 × 1,226 × 432 mm x 74.5kg with the tabletop stand. My chippie says 75kg is way too much to wall mount without steel-reinforced studs.

 GadgetGuy’s take – Sony Z9G – 8K now or wait

While I am sure Sony would like to sell heaps of these, the fact is that it, Samsung and LG’s 8K TVs are more proof-of-concept than mainstream devices.

I have yet to understand all the issues surrounding HDMI 2.1, local dimming, motion control, pixel dimming and other technologies that are going to make 8K mainstream. If it were my $26K I would want to be sure I knew what was best.

From what I saw picture quality is good but sub-native 4K, features are less than future 8K units will deliver and all TV makers need to work on V2.0 – never buy V1.0.
