1. LG OLED48CX

LG has produced the first sub-50in OLED of the 4K era – and it’s just as brilliant as we’d hoped.

SPECIFICATIONS

Screen size: 48in (also available in 55in, 65in, 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): 24" x 42" x 1.8"

Reasons to Buy

Flagship-level OLED performance
Dramatic but natural picture
Forward-looking feature set

Reasons to Avoid

Expensive for its size

We've been waiting for this moment for a long time. Finally, you can buy a 4K OLED TV that's smaller than 55 inches. In fact, it's quite a lot smaller: the OLED48CX is, you guessed it, a 48-inch TV, and therefore brings flagship OLED performance to under 50 inches for the first time.

And it really is a fabulous performance. This isn't a downgraded flagship TV - it's a downsized flagship TV. It offers the same performance and features as its bigger brothers in the CX range (which, let's remember, also match the more expensive GX, RX and WX in terms of picture quality and processing), but in a smaller, more living room-friendly package.

The performance is superb. The perfect blacks and near-perfect viewing angles we're used to from OLED, combined with bright, punchy whites and vibrant but natural colors. LG's motion processing in 2020 is the best it's ever been, too, and its OLEDs continue to impress in terms of upscaling 1080p and standard-def content.

On top of all 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). Those last two features will be of particular appeal to those gamers looking to upgrade to the PS5 or Xbox Series X this Christmas.

2. Samsung UN55TU8000

The new TU8000 represents exceptional value for money.

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): 28" x 48" x 2.4"

Reasons to Buy

Brilliant HDR picture
Bags of tonal detail
Punchy colors

Reasons to Avoid

Not particularly bright
Uninspiring sound

Samsung's 8-series has traditionally been positioned just below the company’s glamorous range-topping QLEDs. In the past, it has proven to be the sweet spot where picture quality and price intersect to maximum effect. And so it proves once more.

The TU8000 is astonishingly good value. For comparatively very little money you're getting a 55-inch TV that performs brilliantly, particularly with HDR content, and boasts the best, most app-laden operating system available at any price.

It's sound is only so-so and it's lacking the outright brightness and next-gen HDMI features of its premium siblings, but it's still undeniably brilliant for the money.

3. LG OLED55CX

The core model in LG’s 2020 OLED TV range is an astonishingly capable all-round performer.

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 UK catch-up apps

We've already covered the new 48-inch version of the CX above, but it's worth remembering that the 55-inch model is still available and arguably offers better value for money.

For not a huge amount more, you get seven extra inches of OLED panel real estate and all of the excellent picture qualities and advanced features of its smaller sibling. It sounds a bit better, too, thanks to the bigger chassis, although the CX isn't the best-sounding TV in its class.

All in all, this is an extremely compelling all-rounder.

4. Samsung QN55Q90T

Samsung’s top 4K model for 2020 is punchy, feature-packed and good value.

SPECIFICATIONS

Screen size: 55in (also available in 65in, 75in) | Type: QLED | Backlight: direct 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): 28" x 48" x 1.4"

Reasons to Buy

Brilliantly bright and punchy
Superb operating system
Improved motion and sound

Reasons to Avoid

Slightly exaggerated colors
OLEDs offer better blacks

The Samsung Q90T is a slightly tricky proposition. It’s the top 4K TV in Samsung’s 2020 TV range, but as a result of the company’s increased focus on 8K models, it’s also less of a flagship model than last year’s Q90R.

Whether you consider the Q90T to be the true successor to the Q90R or not, it is a better TV overall. It has a more natural balance, significantly better motion and a much-improved sound system. It’s true that it doesn’t go quite as bright or quite as black but, in fairness to Samsung, the Q90T is also more aggressively priced.

More important than how it fares against its discontinued sibling, though, is how it fares against similarly priced 2020 TVs such as the LG OLED55CX. This set goes blacker and produces brighter highlights in otherwise dark images, but the Samsung is vastly punchier with almost everything you watch and images pop from the screen in a way that OLEDs still can’t match. It also has the best, most app-packed operating system by quite a margin, and a feature set that will keep it relevant for years to come. 

There’s no doubt that the Samsung Q90T is an excellent TV, and you certainly shouldn’t discount it for not being an OLED or not having as many dimming zones as its ‘predecessor’.

5. Sony XBR-55A8H

Sony’s top 2020 OLED (so far) is one of its best TVs yet.

SPECIFICATIONS

Screen size: 55in (also available in 65in) | Type: OLED | Backlight: not applicable | Resolution: 4K | HDR formats supported: HDR10, HLG, Dolby Vision | Operating system: Android TV 9 | HDMI inputs: 4 | ARC/eARC: eARC | Optical output: Yes | Dimensions (hwd, without stand): 28" x 48" x 2"

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

This set is practically all screen – the black bezel is flush with the screen so you don’t notice it when the set is off. The fact it's so thin puts the emphasis squarely on the screen.

And what a screen it is. Images are beautifully natural, lending themselves to a cinematic authenticity that's great for movies. Dark detail is a particular highlight, though in high contrast sections (like white credits on a black screen) the Sony tends to play it a little safe. We would've liked more punch.

Typically for a Sony, the motion processing is superb, and SDR content remains vibrant and dynamic. It even makes standard definition content watchable. Just.

On the audio side, the A8 lacks a little bass depth and weight, but otherwise impresses with its crisp, dynamic delivery. It sounds a lot better than most of its similarly-priced rivals, though of course we would always recommend partnering it with a dedicated sound system to really enhance the experience.

6. LG OLED65GX

LG’s 2020 OLED TV range gets off to a superb start with this beautifully designed ‘Gallery’ model

SPECIFICATIONS

Screen size: 65in (also available in 55in, 75in) | Type: OLED | Backlight: Not applicable | Resolution: 4K | Operating system: webOS | HDR formats supported: HDR10, HLG, Dolby Vision | Operating system: webOS | HDMI inputs: 4 | ARC/eARC: eARC | Optical output: Yes | Dimensions (hwd, without stand): 33" x 57" x 0.8"

Reasons to Buy

Consistent, natural performance
Improved motion and dark detail
Lovely design

Reasons to Avoid

No feet or pedestal in the box

LG's first 2020 OLED is brilliant. While we'd usually like to start the year with the C-class model, which is the most affordable set with all of the best picture processing, this GX takes that same picture and adds more powerful sound and a beautiful design.

This is LG's 'Gallery' model, and as such is entirely intended for wall-mounting. You don't even get a stand in the box (although feet can be bought separately), with a low-profile mount provided instead. The set is a uniform 2cm deep, which is exceptionally slim. 

Picture-wise, LG has taken the exemplary performance of its 2019 OLEDs and improved it in a few key areas, with dark detail, color richness and motion handling all getting a worthwhile boost. The set sounds decent, too, particularly for one with essentially invisible speakers.

7. Sony XBR-49X950H

The 49X950H is the latest in a long line of superb 49in TVs from Sony.

SPECIFICATIONS

Screen size: 49in (also available in 55in, 65in, 75in 85in) | Type: LCD | Backlight: Direct LED | Resolution: 4K | HDR formats supported: HDR10, HLG, Dolby Vision | Operating system: Android TV 9.0 | HDMI inputs: 4 | ARC/eARC: eARC | Optical output: Yes | Dimensions (hwd, without stand): 25" x 43" x 3"

Reasons to Buy

Punchy, rich picture performance
Vastly improved sound
Snappy user experience

Reasons to Avoid

Same design as last year
Some backlight bloom

There's a lot of pressure on the 49in XBR-49X950H, as all three of its predecessors have taken home What Hi-Fi? Awards. While other challengers will emerge before the 2020 Awards deadline (the 49in version of the Samsung Q80T and 48in LG OLED CX could be very good), Sony's put itself in a great position to make it four in a row.

The company has basically reused the shell of last year's X950G, which is a bit of a shame as it's fairly thick and has awkward-looking feet that give the set an overly wide footprint. But the set looks fairly smart in its own right. You do also get a better remote that's neatly laid out and doesn't require line of sight in order to send commands to the TV.

Most importantly, last year's shell has been stuffed with upgraded kit, including Sony's flagship processor, the X1 Ultimate, which brings with it lots of picture improvements. All told, this is a punchier and more richly colored performer than its predecessor, with more dark detail and the excellent motion processing for which Sony is renowned. It sounds impressively weighty and solid, too.

Other than a bit of blooming from the direct LED backlight, this is a great buy, and the new benchmark for 49 inch TVs.

8. Samsung QN55Q80T

This 2020 TV is an excellent value proposition

SPECIFICATIONS

Screen size: 55in (also available in 49in, 65in, 75in, 85in) | Type: QLED | Backlight: direct 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): 27.8" x 48.3" x 2.1"

Reasons to Buy

Excellent contrast and colors
Three-dimensional and detailed
Solid, spacious sound

Reasons to Avoid

Occasionally overcooks colors
Slightly exaggerates film grain

This new Samsung QLED sets a formidable benchmark for 55 inch TVs in 2020, offering a high-end performance at a fairly mid-range price.

The Q80T looks much like any other Samsung QLED, but that's no bad thing. Inside there are four HDMI inputs, which support the key features of HDMI 2.1, such as eARC, VRR and HFR. 4K HDR streaming is available via the likes of Netflix, Amazon Prime Video, Disney+, Apple TV+. In fact, the app support is superb, with pretty much every video and music streaming site you can think of on offer here. The only feature gap of real significance is the lack of Dolby Vision.

A simple TV to set-up when it comes to getting the best possible picture, the Q80T ultimately delivers a brilliantly dynamic image with deep black levels, excellent contrast and neutral but vibrant colors. While there are rare occasions when watching HDR that a skin tone seems slightly overcooked, the color balance is a great strength overall, while motion is handled confidently and smoothly throughout our testing. And while we'd recommend a soundbar or some speakers, Samsung's Object Tracking Sound technology provides open, engaging audio.
