Sony has developed an excellent sound signature and pre-sets that cover most bases. But no matter what the content the TV speakers still present as 2.1 channels.
If you are buying a Master Series TV reserve a few extra grand to get a full Dolby Atmos 7.1.4 (or 5.1.2) receiver or soundbar.
Interestingly the TV can become the centre front (clear vocal speaker) with a companion Sony 7.2 or 5.2 Dolby Atmos receiver and four/six external full-range speakers and two sub-woofers for 9/7 speaker channels. The benefit of the Sony AV receiver system is the dual sub-woofers can produce deep, room-shaking bass (35Hz up to 200Hz).
Hearing-impaired – take note
Sony is one of the few TVs that can support Bluetooth headphones at the same time as the TV speakers (but not an external audio system). PASS with caveats – you need an external system to get Dolby Atmos.
I have a late model Sony LCD TV with the latest version of Android TV, so it’s the same interface as the review TV.
Let’s just say that over the past two years, Android TV has gone from more experimental to well-polished, and it’s Google Assistant integration is flawless. It also has the most extensive range of apps of any TV OS, and you can attach a BT keyboard and mouse for added productivity.
You can either use the two far-field mics on the TV or press the remote button to access OK Google. Amazon Alexa comes via the Amazon Prime App.
One interesting new feature is the ability to live stream FTA TV without the need to connect to a TV antenna. Streaming content requires a 25MBps or more NBN connection and unlimited data is almost mandatory.
It also has Chromecast to allow Android and iOS to cast to the screen. Apple’s TV app, AirPlay 2, and HomeKit will come via a later software update.
Sony A9G Design/build
Like the previous A9F, there is no room under the desktop stand for a soundbar – it is as if Sony expects you to wall-mount it, Sony does not supply its excellent VESA 300×300 SU-WL850 telescopic mount or its lower cost SU-WL450 wall mount in the box.
The screen has very narrow bezels and being OLED means it is essentially just a glass pane attached to the electronics box at the back.
The back is fully enclosed, but you can remove panels to get to the main ports. Heat is not an issue at all – after a few hours, our Kestrel Drop sensor recorded 38° at the back and 33° at the front.
Other brands of TVs can reach 45°, and prolonged exposure to heat can damage paintwork etc.
Sony build quality is superb, and even though the TV is ‘half’ glass you feel confident of picking it up and moving it.
The new remote is slimmer and lighter and connects via BT to the TV. It has a microphone button and dedicated Netflix and Google Play.
Size: with Table-Top Stand
- 77A9G: 1,721 × 1,001 × 302 mm x 39.7kg
- 65A9G: 1,447 × 838 × 255 mm x 24.8kg

Standby is .3W, and max power 55/65/77 is 373/469/653Wh or from 13 to 30 cents per hour (depends on tariff). This is typical of a 65-inch OLED or QLED panel but about twice that of a standard LED/LCD edge-lit panel.
