What better place to review a Sony A9G Master Series OLED king-size TV than in a king-size bed replete with snacks in a cloistered suite at the iconic Old Claire Hotel?

One of the perks we tech journalist get is an overnight stay to review a TV. In this case, it was the 65-inch Sony A9G Master Series OLED. I spent the night watching copious 4K, Dolby Vision (not Dolby Atmos – more later), content from Netflix et al. A sci-fi binge delight.

What is the Master Series?

Let’s just say that Sony is trying to cement itself as a premium OLED TV provider. The Sony A9G Master Series in 55, 65 and 77-inches at $5,199/7,199/14,399 is the best it can offer.

Under the Master Series is 55/65-inch A8G OLED at $3,495/4,995. I could go on, but we covered the 2019 launch range here.

So, I will avoid the hyperbole until my summary. The suffix ‘G’ means 2019 model – F is for 2018.

In fact, we reviewed the A9F Master Series 2018 here scoring it at 4.5-out-of-5. It was Sony’s best to date, but we felt that it needed a little tweaking to take the ultimate crown.

On that note, both the Sony A9G and A9F use the same X1 Ultimate Processor and Android TV O upgrades since then have probably added a couple of points to the rating. So, if you see a lower cost 65-inch A9F (under $5,000) snap it up because the A9G is not a quantum leap – more a refined one. Is a bit slimmer, has a new remote and not too much more.

Note: some countries use the nomenclature AG9 – it is the same TV but for a different region.

Sony A9G 4K video tests

Armed with 4K TV testing software – a greyscale generator, colour bars, tone generator and a few tests for DCI-P3 colour gamut I put the TV through its technical paces. Spoiler alert: PASS

Colour bars

As expected of any OLED with pixel-level control, it gave good, rock-solid colour bars with clear definition between bars – no overlap. There were no bands of lighter and darker colours that you see with many LED/LCD TVs. PASS.



As an OLED with individually controllable light-emitting pixels (as against various forms of edge-lit or backlit dimming in LED/LCD) it theoretically has infinite contrast from pure black (pixel off) to 100% white. PASS


SDR (standard dynamic range): The Vivid pre-set can reach over 650 nits (momentarily), but the reality is between 150 and 500 nits depending on the image. The more white on the screen, the lower the nits. This is fine for free-to-air (FTA) TV and SDR content.

HDR (High dynamic range): HDR means more brightness and contrast control (*but you need reasonable ambient light control of your surroundings). If you drive the TV flat out, you can get 800nits. But again, the reality with true HDR/HDR10/Dolby Vision content is from 125-650 nits. PASS
