1. LG OLED55CX

LG's stunning OLED TV is a remarkably capable all-rounder

SPECIFICATIONS

Screen size: 55in (also available in 48in, 65in and 77in) | Type: OLED | Backlight: not applicable | Resolution: 4K | HDR formats supported: HDR10, HLG, Dolby Vision | Operating system: webOS | HDMI inputs: 4 | ARC/eARC: eARC | Optical output: Yes | Dimensions (hwd, without stand): 28" x 48" x 1.8"

Reasons to Buy

Picture is exciting but natural
Improved motion and dark detail
More future-proofed than most

Reasons to Avoid

Missing some catch-up apps

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 the best 55-inch TV we've tested. What's more, because it's no longer LG's newest model, there are serious savings to be had on this mid-size MVP.

2. Samsung UN55TU8000

This 2020 mid-range model is stunning value for a 55-inch TV.

SPECIFICATIONS

Screen size: 55in (also available in 43in, 50in, 65in, 75in and 82in) | Type: LCD | Backlight: edge LED | Resolution: 4K | HDR formats supported: HDR10, HLG, HDR10+ | Operating system: Tizen | HDMI inputs: 4 | ARC/eARC: eARC | Optical output: Yes | Dimensions (hwd, without stand): 71 x 123 x 6cm

Reasons to Buy

Brilliant HDR picture
Bags of tonal detail
Punchy colours

Reasons to Avoid

Not particularly bright
Uninspiring sound

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.

3. Samsung QN55Q90T

Samsung’s top 4K model from 2020 delivers a dynamic picture.

SPECIFICATIONS

Screen size: 55in (also available in 65in and 75in) | Type: QLED | Backlight: LED full array | Resolution: 4K | HDR formats supported: HDR10, HLG, HDR10+ | Operating system: Tizen | HDMI inputs: 4 | ARC/eARC: eARC | Optical output: Yes | Dimensions (hwd, without stand): 71 x 123 x 0.4cm

Reasons to Buy

Brilliantly bright and punchy
Superb operating system
Improved motion and sound

Reasons to Avoid

Slightly exaggerated colours
OLEDs offer better blacks

The pricier Samsung Q90T is one of Samsung's best 2020 4K TVs. It's not quite a flagship model, but it does boast a spec sheet that's loaded with more extras than an In-N-Out burger. 

In fact, we'd go so far as to say the Q90T is an excellent alternative to its (much pricier) OLED rivals. PS5 or Xbox Series X owners will love this model, too. It's heaving with gamer-centric features such as eARC, HFR (High Frame Rate), ALLM (Auto Low Latency Mode) and VRR (Variable Refresh Rate). It also has an input lag of just 11ms.

Of course, the Q90T's QLED panel is also a great choice for movies and TV, being noticeably brighter than its OLED rivals. Samsung has knocked it out the park in terms of sharpness and detail, and the the balance between punchiness and natural tone is to be applauded. Audio ability is decent, with a good combination of spaciousness and directness. 

If the Q90T falls within your budget, this is one of our top 55-inch TV picks.

4. Sony XBR-55A8H

Put simply, this is one of Sony's best ever 55-inch TVs.

SPECIFICATIONS

Resolution: 4K | Screen type: OLED | Operating system: Android TV | HDR formats: HDR10, HLG, Dolby Vision | HDMI: 4 | USB: 3 | Optical: 1 | Dimensions: 123 x 71 x 5.2 cm (w/out stand)

Reasons to Buy

Natural and authentic picture
Superb motion handling
Crisp, involving sound

Reasons to Avoid

High-contrast images lack punch
Lacking next-gen HDMI features

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.

5. LG OLED55C9

Superb OLED TV with flagship picture performance.

SPECIFICATIONS

Resolution: 3840x2160 | Operating system: webOS | HDR formats: HDR10, HLG, Dolby Vision | HDMI: 4 | USB: 3 | Optical: 1 | Dimensions (HWD with stand): 74 x 123 x 25cm (w/out stand)

Reasons to Buy

Excellent colours and detail
Inky dark blacks
Genuine upscaling class

Reasons to Avoid

Finest dark details missing
Sound isn’t spectacular

With its delicious colours, intense blacks and razor-thin panel, this What Hi-Fi? Award-winner is another fine OLED from LG. It's a great-looking TV, with a sleek design, and has the feature set to match. It might be an 'older' model (having launched in 2019) but the price has dropped considerably, so it's now an absolute steal and well worth considering.

The impressive feature count includes a nifty gesture remote, support for Dolby Atmos audio, a generous helping of inputs and outputs, and wide offering of streaming video and catch-up services including Netflix, Prime Video, Google Play Movies & TV, Hulu, Showtime and more.

There’s also an Alexa app you can install to voice control your TV usage, plus Google Assistant too. HDR is taken care of by Dolby Vision, HDR10 and HLG. Sound is average and a little more peak panel brightness might help with those dark details, but for the money, this 2019 panel remains one of the best 55-inch TVs on the market.

6. LG OLED55E9

An impressive OLED picture with the sound to match.

SPECIFICATIONS

Type: OLED | Resolution: 4K | HDR support: HDR10, Dolby Vision, HLG | HDMI inputs: 4 | Dimensions (hwd, with stand): 75 x 123 x 5cm

Reasons to Buy

Deep, rich blacks
Superb sense of realism
Solid, weighty sound

Reasons to Avoid

Motion could be more natural
Not the last word in black detail
No HDR10+ support

This svelte OLED TV sports LG's sleek 'Floating Screen' design, giving it a minimalistic look. Despite the thin profile, it's stuffed full of features including LG's 2019 AI Sound audio processing technology. In fact, you'd need to spend upwards of $500 on a soundbar to improve the audio significantly.

Of course, the main attraction here is the picture. LG’s clarity and crispness produces an immense sense of depth, even when faced with fast-moving sports such as NFL or Formula 1. It's extremely convincing and does a decent job of upscaling standard definition content. 

The E9 provides easy access to all of your favorite streaming apps, including Netflix, Prime Video, Disney+ and Hulu, as well as pay-as-you-go movie streaming services such as Google Play Movies & TV.

There's support for the Dolby Vision HDR format and four HDMI inputs that all meet the HDMI 2.1 standard, meaning they can support eARC (Enhanced Audio Return Channel) and VRR (Variable Refresh Rate). That's good news for gamers.

All in all, this 2019 continues to hold its own and sets the bar high with superb performance at an increasingly-affordable price.

    Not necessarily - the Panasonic was reviewed a year earlier than the Sony.
