Best 4K TV 2020: 7 top UHD TVs you can buy right now

The definitive Trusted Reviews list of the seven best 4K, ultra high definition TVs on the market in 2020

What’s the best 4K TV for most people?

Scroll through any online store and you’ll see 4K TVs covering every size and price point you can think of, and not all of them will be worth your time or money.

These are both factors you’ll need to consider before buying a new 4K TV. Pick a TV that is too big and you’ll end up ruining the feng shui of the room you put it in. Get one that’s too small and you’ll spend your life squinting.

Price is doubly important as a high up front doesn’t always equate to industry leading picture or audio quality. The best advice we have is to always check review sites, like Trusted, that test for key things like contrast ratio and colour accuracy before investing in a top end TV. If that’s not possible, then you should always look for certain badges of quality.

If you’re looking for a top end TV that offers the absolute best picture quality, you should always try and invest in an HDR (High Dynamic Range) certified set. There are multiple standards around at the moment, but the most common is HDR10 or Dolby Vision. Then you should check audio quality. If you don’t have a dedicated sound system you’re going to want to factor in the TV’s inbuilt speakers.

Clear on what you’re after? Then scroll down to see the top 4K TV sets Trusted Reviews has tested. If you’re in a rush you can get the cliff notes bullet point list of the best 4K TVs we’ve reviewed below.

LG 55C9

1. LG C9

One of the smartest OLEDs money can buy


  • Impressive image accuracy
  • Amazing blacks and contrast
  • AI-enhanced smart platform
  • Dolby Vision and Atmos
  • Incredibly low input lag


  • Limited HDR brightness
  • No HDR10+ support

LG’s latest OLED range has lived up to expectations and then some, with both the C9 and E9 making this list of best 4K TVs.

There’s not much difference between either set, with both delivering AI-enhanced picture and sound, as well as a comprehensive and intuitive smart platform. The C9’s design is not as grand as the E9, but that’s the only significant difference between them. The only disappointing aspect is the C9’s lack of HDR10+.

Even with that omission, with its support for HDMI 2.1 and WiSA (Wireless Speaker and Audio) technology, the C9 is future-proofed for years to come.

2. Panasonic TX-55GZ1500

Fantastic picture quality in almost every way


  • Beautifully refined and detailed picture quality
  • Strong sound from the Blade speaker
  • Easy-to-use smart system


  • Slight banding in HDR colour blends
  • Occasional motion stutter
  • Smart system is less sophisticated than some rivals

After its Plasma range went the way of the Dodo, Panasonic licked its wounds and has come back even stronger with its impressive OLED sets.

The GZ1500 is not even the top range effort, but features excellent near-black light management, which helps to produce a rich, natural looking image. And even though it’s a flatscreen set, attention has been paid to the sound quality with the inclusion of ‘Blade’ speakers that reduce the need for an external soundbar.

Both the 55-and 65-inch are exclusive to John Lewis stores.

3. Samsung QE65Q90R

A superlative TV


  • Groundbreaking contrast for an LCD TV
  • Groundbreaking viewing angles for an LCD TV
  • Fantastic HDR performance


  • No Dolby Vision support
  • Some missing shadow detail in Standard mode
  • Motion could be handled better

The Q90R gets closer than any LED set before it to meshing the characteristics of LED and OLED. It’s jam-packed full of features, with Auto Game Mode, excellent upscaling abilities and wide viewing angle tech for an increased range of viewing positions.

Samsung’s QLEDs don’t support Dolby Vision, but otherwise, the Q90R produces a bright, punchy and intense performance.

The QE65Q90R is a showcase for some of the most spectacular HDR pictures we’ve seen yet.

4. Philips OLED804

Outstanding OLED picture quality


  • Extremely sharp, detailed, vibrant pictures
  • Support for both HDR10+ and Dolby Vision
  • Great price for what’s on offer


  • Colours flare out in Vivid mode
  • Potential for MPEG noise with dark streamed video
  • Sound is a little light on bass

Ticking a number of boxes and hitting a relatively low price for a new OLED, the OLED804 is a 4K TV to keep an eye on.

Replacing 2018’s OLED+803 range, the OLED804 has a more powerful, 3rd-gen, two-chip version of the P5 picture processor, a great-looking design that melts into the room and an enjoyable 2.1 sound system.

Dolby Vision and HDR10+ are supported and the Philips looks great in either format, supplying a refined, but still richly colourful image (especially in Vivid mode).

LG E9 LG TV 2019

5. LG E9

An outstanding OLED package


  • Terrific image quality
  • Comprehensive feature set webOS functionality
  • Very good audio performance
  • Low input lag


  • No HDR10+
  • Settings and modes can be a maze to navigate

Like the C9, the E9 is another terrific OLED TV from LG. It comes stacked with features – although the omission of HDR10+ means it’s not complete.

Otherwise it has almost everything you could want from a modern day TV, with voice assistants, excellent gaming performance as well as the rich, colourful HDR images with deep blacks we’ve come to expect from OLEDs. A special mention for the sound quality, which is surprisingly hefty.

6. Sony KD-65AG9

A fantastic flagship OLED from Sony


  • Bright, effective HDR
  • Best in class HD SDR upscaling
  • Excellent audio


  • No HDR10+ support
  • No Freeview Play

Sony’s current flagship OLED is a stylish effort from the Japanese manufacturer, and is arguably Sony’s best OLED yet.

Like LG, the AG9 isn’t ostentatious when it comes to design adopting a “less is more” approach. The TV supports Android TV OS and the latest version is better than previous ones, but there’s no Freeview Play which disappoint some.

The AG9 puts in an impressive picture performance with bright HDR, and excellent – as usual from Sony – motion processing and upscaling of HD SDR images. The Surface Audio+, which shakes the screen to produce sound, is an impressive feat of technology too.

Hisense O8B

7. Hisense H55O8BUK

A very affordable OLED TV


  • Impressive picture quality
  • Great blacks and contrast
  • Simple but effective smart platform
  • Dolby Vision and Atmos
  • Competitively priced


  • Limited HDR brightness
  • No HDR10+ support

Hisense’s first OLED– the H55O8BUK – is a fine, affordable effort.

Like other OLED models, it takes advantage of is credit-card thin screen for an ultra-slim and attractive look. The VIDAA U smart platform is relatively simple, but features catch-up and on-demand services you’re likely use.

It lacks the AI enhancements and voice assistants more expensive sets have, but delivers where it counts with a punchy 4K HDR performance. If you don’t want to break the bank for an OLED TV, the O8B meets those expectations.

What you need to know abut buying a 4K TV

What is a 4K TV?

4K TVs have four times as many pixels as Full HD TVs. When you have that much more information in the same screen sizes, your picture ends up much sharper and clearer, and you can really appreciate all the extra definition and detail.

Many say 4K TVs can almost appear as if they’re in 3D, thanks to the amount of depth an image can offer. Some refer to 4K TVs as UHD (Ultra HD), but for TV-buying purposes, they are just different ways of naming the same thing.

How we test 4K TVs

  • Our crack team of 4K TV reviewers use both their naked eye and specialist tools to check every set they test for contrast, black level, maximum brightness and input lag, plus any hint of backlight bleed, blooming or anything else that might spoil your viewing enjoyment.
  • A variety of test footage is used to cover every type of scene, so we can assess a 4K TV’s strengths and weaknesses, as well as how it performs against the competition.
  • Sound quality isn’t forgotten, either – we give the built-in speakers a thorough listen to determine whether you’ll need to invest in a soundbar or speaker system to beef things up.
