The best 55-inch 4K TVs are the best place to start if you're on the hunt for a new television. These days, 55-inch is the flagship size for any TV brand, meaning it gets the biggest spread of quality televisions.

Sure, if you want something more impactful, you can opt for the best 65-inch or even 75-inch screens – but for a happy medium between scale, price and practicality, the best 55-inch 4K TVs are where it's at.

Other TV sizes to consider

If you’re concerned that opting for a 55-inch TV might mean you’re scrimping in the features or performance departments, don’t worry. Most 55-inch TVs that you can buy nowadays offer support for HDR, 4K resolution and will have built-in smart TV services too. 

You'll find both QLED and OLED TVs in this size range, so you're not being locked out of any display technology, and most times you'll find a pretty good processor inside that can make even old HD images look brand-new.

That said, with size, manufacturer, LCD or OLED there may be a lot to consider – but we're here to point you towards some of the best 55-inch 4K TVs available to buy. All the sets we’ve listed below have been tried-and-tested by our expert reviewers, and you can click through to read the full reviews for more about the pros and cons of each model.

1. Best 55-inch TV: LG CX OLED

A mesmerizing OLED TV

48-inch: LG OLED48CX | 55-inch: LG OLED55CX | 65-inch: LG OLED65CX | 77-inch: LG OLED77CX

Stellar picture quality
Gorgeous super-slim design
Heavy bass can distort
No HDR10+ support

The LG CX OLED is topping a lot of our TV buying guides, and for good reason. Packing a high-contrast OLED panel, LG's brilliant webOS smart platform, and an upgraded a9 Gen 3 processor, there's really very little not to like.

You'll find exceptional picture quality, with endlessly deep blacks, an infinite contrast ratio, and processing fully able to make all those millions of pixels pull their weight. 

The 55-inch size is also a smart size to buy the CX, given the generally high price of OLED TVs. stopping short of a 65-inch or 77-inch will keep the price somewhat down – though those after more of a saving can opt for the new 48-inch OLED size LG introduced for 2020 too.

The display is also incredibly thin, at just a couple of millimeters deep – while still managing to fit in four HDMI 2.1 ports (with eARC too) and a brilliantly low input lag, meaning this is one set able to handle those next-gen consoles coming later this year.

The only real letdowns are the absence of HDR10+ (LG prefers Dolby Vision HDR) and (for UK viewers) Freeview Play. If you can overlook these faults, though, there's little reason not to make the CX your new television in 2020.

2. Best on a budget: TCL 6-Series Roku TV (US only)

TCL’s affordable 6-Series continues to shine as a beacon of hope for budget TV buyers

Screen size: 55-inch | Tuner: N/A | Resolution: 3840 x 2160 | Panel technology: LED | Smart TV: Roku TV | Curved: No | Dimensions: 1,239 x 717 x 36 mm

Bright, colorful HDR
Roku TV is amazing
Upscaling isn’t world-class
Poor black level performance

While we could easily fill this list with TVs that cost thousands, we try to measure screens by how well they perform for their price - and, by that metric, there are few TVs better than the TCL 6-Series QLED (55R625). 

Thanks to the addition of Quantum Dots, the 6-Series is more colorful than ever before and the new AIPQ engine makes upscaled content look even better than last year, too. It may not be able to output the same peak brightness as QLED TVs from Samsung and Vizio, but it costs less than half of the competition. 

We can't recommend it highly enough.

3. Best premium 55-inch TV: Sony A9G/AG9 OLED

The A9G Master Series is an OLED to take on the best

Screen size: 55-inch | Tuner: Freeview HD/Freesat | Resolution: 3840 x 2160 | Panel technology: OLED | Smart TV: Android TV | Curved: No | Dimensions: 1226 x 714 x 255mm (W x H x D)

Top-class upscaling
Acoustic Surface+ audio
Lean back design
No Freeview Play, or HDR10+

Why buy the A9G OLED? The 2019 model excels when it comes to upscaling, with SD and HD images looking as polished and detailed as you could hope for on the A9G’s 4K display – while the OLED panel manages to draw out incredible color and contrast performance. 

Sound is also a key feature, with Sony’s premium Acoustic Surface+ Audio technology emitting audio out of the panel itself, rather than jutting out of rear-firing speakers.

There are some specific flaws worth noting, including the lack of Freeview Play – the on demand service for British broadcasters. While you get premium Dolby Vision and Dolby Atmos formats, there’s also no HDR10+, which may be an issue depending on which streaming services and HDR sources you use. The A9G is, however, IMAX Enhanced certified for those keen on the cinematic aspect ratio and DTS-mixed audio that affords. 

If you can afford the eye-watering price, this is one of the best 55-inch TVs out there.

Samsung 4K QLED Q95T

4. HDR champ: Samsung Q95T QLED TV

An affordable Q90 successor with OTS audio

Screen size: 55-inch | Tuner: Freeview/FreeSat | Resolution: 3840 x 2160 | Panel technology: QLED | Smart TV: Samsung Tizen | Curved: No | Dimensions: 227.6 x 794.8 x 235.6mm (W x H x D)

Very good sound quality
Strong gaming features
Not cheap
Aggressive backlight dimming

The Samsung Q95T holds a curious position in this year's TV range, given it's not as high specified as its Q90 predecessor – but there are a few changes to make up for it.

For one, it uses Samsung's new-for-2020 audio system: OTS (Object Tracking Sound). This uses a number of different drivers placed around the screen to ensure audio can track up, down, left and right in response to what's happening onscreen. You're also getting a significantly lower starting price than the Q90 (which is essentially out of stock now, anyway).

As ever, the Q95T QLED is exceptionally bright, too, making for dazzling images. The backlight dimming can be a bit aggressive (in order to prevent blooming around bright objects) but it's a small price to pay for what's still an exceptional HDR performer.

In Dynamic Mode it achieves brightness peaks of more than 2000 nits. This drops to around 1500 and 1300 nits respectively in the more all-round effective Standard and Movie presets, but that’s more than enough to ensure the Q95T delivers HDR pictures with exceptional punch and vibrancy. 

Samsung's new Ultra Viewing Angle technology also maintains the depth of color off-axis, making for an exceptional LCD TV.

5. For wow factor: Philips OLED 803 4K

Philips redefines reality with next-gen P5 image processor

Screen size: 65-inch | Tuner: N/A | Resolution: 3840 x 2160 | Panel technology: OLED | Smart TV: Android N | Curved: No

Superb image performance
Three-sided Ambilight
Designer good looks
No Freeview Play
Android update is long overdue
Only two full-specification 4K HDMI inputs

Philips has significantly upgraded the picture processing power of its 2018 OLED TVs, and the benefits of this new-found brawn can be seen writ large, with enhanced contrast and spectacular colors. 

The brand’s second generation P5 Perfect Processing Engine offers twice the picture processing power of the original, and that was a pretty impressive chip in its own right.

But the main draw may be what Philip's Ambilight lighting system brings to the viewing experience, throwing colors over the wall in a full-on feast for the eyes. Why limit the picture to just the television, after all?

Buyers should weigh the visual benefits against the minor irritations, like poor catch-up TV provision, just two full-spec UHD HDMI inputs, and the lack of Dolby Vision. 

But the jazzy colors of the Philips Hue-compatible Ambilight room lighting system, and the eventual rollout of the Android Oreo smart system – as of June 2019 – could just manage to balance the books.

6. The starter OLED: LG B9 OLED

OLED on a budget

Screen size: 55-inch | Tuner: Freeview Play, Freeview Satellite | Resolution: 3840 x 2160 | Panel technology: OLED | Smart TV: WebOS | Curved: No | Dimensions: 1228 x 744 x 246mm (W x H x D)

LG's cheapest OLED
Incredible color contrast
Less advanced processing
Some video noise in dark scenes

Want a top-notch OLED panel, without the associated cost? You may want the LG B9 in your living room.

The B9 was a bit late to the party, only landing in the second half of 2019, but its low price point compared to the C Series or E Series makes it a tempting proposition. Of course, that affordability comes with a catch, as the B9 uses the a7 Gen 2 processor, instead of the more advanced a9 Gen 2 chip.

This means you’re not getting the best picture processing available – but aside from some mild video noise in dark scenes, and the occasional drop in frame rate, you’re still getting a high-quality picture at a (comparatively) cheap price.

You'll still be getting the expected 4K resolution, HDR support, and brilliant webOS smart platform of the best LG TVs too.

7. Best feature: Philips OLED 754

Ambilight is the jewel in this entry level OLED's crown

55-inch: 55OLED754 | 65-inch: 65OLED754

Great visuals
Ambilight is still cool
Saphi interface can be a chore
Motion settings need fine tuning

We're starting to enter an age of affordable OLEDs, and that's nowhere clearer than with the Philips OLED 754. Available now for just £999 in the UK, down from its initial £1,300 RRP, it's a fantastic example of the kind of quality already on offer for mid-budget TV buyers (along with the LG B9).

You won't get some of the bells and whistles of other, more high-end TVs in this list, but you do get universal HDR support – something even the LG CX OLED is lacking.

The inclusion of three-sided Ambilight, too, is still a thrill, offering a lightshow behind the television for ambience (ambi-light, get it?) and feeling fully unique in its offering.

The Saphi smart TV platform could use some work, but this really is a knockout OLED TV, and the second-gen P5 processor still works wonders on an OLED panel.

8. The budget pick: Samsung RU8000 (UN55RU8000, UE55RU8000, UA55RU8000)

Samsung TVs don’t always need QLED to impress

Screen size: 55-inch | Tuner: Freeview Play, Freeview Satellite | Resolution: 3840 x 2160 | Panel technology: LED | Smart TV: Tizen | Curved: No | Dimensions: 1237.2 x 776.9 x 237.2 mm (W x H x D)

Excellent value
Impressive smart TV platform
Slightly flimsy build quality
Occasional black level issues

While there’s no doubt that Samsung’s ‘QLED’ Quantum Dot technology delivers a premium experience, it also comes with a premium price tag attached. 

Cue the Samsung RU8000 series that offers up plenty of bang for your buck thanks to its impressively comprehensive smart system and user-friendly interface - including Bixby voice control. Forgoing QLED technology does cost the RU8000 a fair chunk of brightness and color range, but if you're after a budget set that looks great in a second bedroom or smaller living room, this is the one to go for.
