Telvision Buying Guide

Which TV you go for really depends on
what sort of viewing experience you'd like.

Here's some helpful information to help
you choose one that's right for you

Screen size

We've got screen sizes from 22" all the way up to 75". But whatever the size, it's always a good idea to consider how far you'll be sitting from the screen.

Huge improvements in picture quality mean that it’s now possible to watch TV on much larger screens. However, although TVs have got bigger, your living room probably hasn’t.

So how do you choose a TV that’s big enough for a great picture without dominating the room? Personal choice is still important, but there is a simple test: ideally, your viewing distance should be 1.5-times the size of your screen.

For example, if you sit between six and seven feet (72-84”) from your TV, then your ideal screen size – measured diagonally, from corner to corner – is 48-55”.

Screen type

Go for OLED if you want a more vibrant picture, LED for energy
efficiency, and curved for the best possible viewing experience.



With OLED (Organic Light-Emitting Diode) technology, each organic cell sitting behind the television screen creates its own light source. As a result, the light is prevented from spreading into unwanted areas, for a smoother, more vibrant motion picture.

This also means that OLED TVs don’t need a backlight, so they can be even slimmer than LED TVs.

OLED benefits:

  • Brighter colours
  • Higher contrast
  • Realistic blacks
  • Faster refresh rates

LED-backlit TVs feature hundreds of small LEDs (light emitting diodes). These backlight the TV producing greater contrast ratios where blacks appear blacker, leading to a sharper image. This also allows them to be slimmer and consume less power.

LED benefits:

  • Energy efficient
  • Thinner models
  • Light weight
  • Displays darker blacks

Curved TV


Curved screens improve side angles, so no matter where you're sitting, you’ll have the best possible viewing experience, with an almost wrap-around effect as the screen fills more of your vision.

You’ll also have each part of the screen an equal distance from the eye, which helps to create the impression that the screen is larger than it is. As a bonus, the concave design helps to cut down on screen reflections.

Curved strengths:

  • Enhanced sense of depth
  • Wrap-around effect
  • Better contrast
  • Wider viewing angle

Picture quality

The more pixels your TV has, the sharper your picture will be.
For instance, 4K models have 9 million pixels, while Full HD has 2 million.

Your TV is capable of showing broadcasted high definition footage. A HD-ready set is able to handle High Definition signal, but does not have a High Definition tuner built-in, so the services would have to come from external sources such as Sky or Virgin.

Full HD displays up to 4x the quality of current analogue and digital broadcasts. It is currently being broadcast in a 1080p format, which uses a ‘progressive’ scan and assumes a widescreen aspect ratio of 16:9, and a screen resolution of 1920x1080. This makes picture detail sharper and more defined, especially during fast motion.

Ultra HD, also known as 4K, is a new class of high-definition resolution that offers unprecedented picture clarity and detail. Even close up, images are clearer, sharper and more realistic because they're created with 8.3 million pixels – 4 times the pixels of a Full HD screen – so you can sit closer or view on a larger TV without the picture looking pixelated.

HDR offers a deeper, more lifelike display, which boosts 4K and gives you even greater colour and contrast. Without HDR, films and TV shows normally need to have their colour content diluted for less advanced screens, but with HDR you will see everything as originally intended.

The UHD Alliance is made up of content creators and distributors, post-production companies, and consumer electronics companies, including Samsung, Sony, Panasonic, Disney, Twentieth Century Fox, Warner Bros and Netflix. Together, they believe for TVs to be awarded with the Ultra HD Premium sticker, they must have the following:

  • 4K resolution (four times the pixels of Full HD)
  • 10-bit colour depth (otherwise known as ‘deep colour’)
  • 90% colour space
  • A minimum contrast range

These measures mean new sets deliver the brilliant colour intensity, inky blacks and bright whites needed to channel content as the creators intended.

When you see the ‘Ultra HD Premium’ sticker, you’re guaranteed to get the very best home viewing.

Smart TVs

Smart TVs seamlessly stream online content through your broadband connection, so you can catch up on your favourite shows and connect to social media.

With a smart TV you can share content from your smartphone, like music and images. You can also watch videos from YouTube, or catch up with the latest on demand services from BBC iPlayer and 4oD, all on your large screen.

Buy a new TV today and it will almost certainly be a ‘smart’ TV, which can be connected to your home internet to receive extra services. When choosing a new television, look at the smart features available – most offer catch-up TV, such as BBC iPlayer and streaming movie services, such as Netflix or Amazon Prime.

If you subscribe to a movie service already, then make sure your new set includes it.

Other options to consider are whether you want access to games, applications and web browsing. The latest generation of smart TVs are even easier to use as they incorporate familiar operating systems such as Android, WebOS and Firefox.

Please note:
A Smart TV is a platform which can run 3rd party Apps. 3rd party content providers may remove Apps from the Smart TV platform or stop supporting them at any time and John Lewis cannot guarantee an Apps' availability. When new Smart TV products are launched, there may be also be a delay before certain Apps become available.

Availability of Apps are not included within the terms of the manufacturer’s warranty or the John Lewis 5 Year Guarantee (2 Year for Audio Visual products).

Sound quality

For an immersive viewing experience, you should consider
enhancing the sound of your TV with a sound bar.

Most TVs feature simple stereo sound or a system that produces a 'virtual' surround sound
effect, but as TVs get slimmer and built-in speakers get smaller, choosing the right sound
system is more important than ever.

Adding a sound bar will allow you to recreate a cinematic experience at home.

Sound bar

A sound bar is for positioning in front of the TV or securing to a wall. Depending on the model, the sound bar will either have a wired or a discreet wireless subwoofer, which enhances bass and depth to the sound quality.

Sound base

A sound base is for positioning underneath the base of the TV screen, ideal if space is limited or if you prefer a more discreet sound-enhancing option. The sound base has an integrated sub-woofer which enhances the power of the built-in TV sound.
