While Sony’s OLEDs are highly regarded, it’s typically hard to justify buying one over a rival LG. Historically, the Sony has a more authentic picture and better sound but is also a step behind on features and usability – and at least a level or two more expensive.
But what if Sony could produce a TV with most of those previously missing features, a more satisfying user experience, and a unique high-quality movie streaming app, all while raising the picture and sound quality to even greater heights? That's exactly what the company's done with the A90J.
In performance terms, the Sony A90J is an absolute stunner. It takes OLED picture performance to new, thrilling levels while maintaining the authenticity for which Sony is justifiably renowned. It also sounds significantly better than all of the other TVs you might be considering. The new Google TV operating system means the user experience is better than that of any pre-2021 Sony TV, too, and the exclusive Bravia Core streaming service is a genuine value-added feature.
Hardcore gamers might want to take a wait-and-see approach, as the set doesn't yet support VRR (an update has been promised but not dated) and we found the 4K@120Hz support a little buggy. However, if movies and TV shows are your priority and you have a big budget, we haven’t tested a better television than the Sony A90J. It’s pricey, but it’s also a clear cut above the competition.

The TU8000 punches well above its weight, performing brilliantly across 4K, HD and standard definition. It's a budget mid-range model, but it arguably represents the best balance of price and picture quality in the company's 2020 lineup.
Its solid build quality impresses and the superb Tizen operating system provides all your favorite streaming apps including the likes of Netflix, Prime Video, Apple TV+, Disney+, Hulu, Showtime, Google Play Movies & TV and YouTube TV.
HDR content looks great on the 55-inch LED panel, with a level of shading and punch that's not a million miles away from that of the company's pricier QLED panels. It does a fine job of upscaling SD content, too.
Sound is decent enough but we'd recommend upgrading to a soundbar. It's also worth noting that you'll need a unit or AV rack that's least 103cm wide to support this set's stand.
Overall, we can't praise the TU8000 enough. This app-laden set is a great value buy that delivers a premium picture at a remarkably-low price. One of the best 55-inch TVs you can buy right now.

Want breathtaking picture quality at a tempting price? This 2020 LG OLED delivers true flagship performance in a lounge-friendly 55-inch form factor.
Perfect blacks and near-perfect viewing angles combine with bright, punchy whites and natural colors to stunning effect. It really is a fantastic TV for those who want a serious home theater experience.
On top of that, you get certified HDMI 2.1 sockets that support next-gen features such as eARC (Enhanced Audio Return Channel), HFR (High Frame Rate), ALLM (Auto Low Latency Mode), and all current formats of VRR (Variable Refresh Rate). In other words, this TV will help you make the most of an PS5 or Xbox Series X.
There's also Airplay 2 built-in, so you can cast Apple's impressive library of Dolby Vision content from your iPhone or Pad to the big screen. You won't be short of streaming apps, either, with the likes of Disney+, Netflix, Paramount+, Hulu, Google Play Movies & TV, Showtime, Starz, Prime Video, Crackle, Apple TV+ and others at your disposal.
While the 2020 CX has been succeeded by the new C1 in LG's 2021 TV line-up, it's still up there with the best 55-inch TVs available. What's more, because it's no longer LG's newest model, there are serious savings to be had on this mid-size MVP.

Sony TVs might have serious competition from the likes of Samsung and LG, but the Japanese tech giant's clever picture processing and innovative TV sound technology make this elegant OLED one of the company's best 55-inch TVs.
The XBR-55A8H gives you the best of both worlds: a top-notch OLED panel made by LG, combined with Sony’s stellar picture and sound technology. The design is a cut above too, with a thin (just over 5cm) profile. That said, it's worth noting that the positioning of the feet means you'll need a large stand to accommodate this TV.
One thing you might not need is a soundbar. Sony uses actuators that vibrate the screen imperceptibly, essentially turning the display into a big, flat speaker. The A8H combines two of these actuators with two subwoofers to great effect, making it one of the best-sounding 55-inch TVs in the US right now.
You get all the usual connections, streaming apps and tech features as well as support for the crucial HDR picture formats. But the real attraction is the picture quality, which majors on realism and authenticity. Whether you're a movie buff or a sports fan, this 55-inch television will not disappoint.
The newer A90J, above, is an even better TV, but it's also vastly more expensive. If you want a big dollop of that top-end Sony OLED performance at a fraction of the price the A8H is a great buy.
