TV buying guide

Watch your favourite programmes on a television which is just right for you with the help of this useful guide. John Lewis offers a wide range of TVs from the latest 4K Ultra HD curved screen to the more compact sets. All our televisions are delivered for free and include a 5-year guarantee for your peace of mind.

Size and design

The demand for larger screen televisions is evident with TVs now as thin as an inch. As a result, this makes the screen much easier to wall-mount. When selecting the screen size which is right for you, it is important to consider how far you will be sitting from the screen. All of our screens have a widescreen viewing ratio (or aspect ratio) of 16:9. This will allow you to see the whole picture as most broadcasts are now transmitted in widescreen.

The screen size shown in the table refers to OLED, LED and Plasma televisions.

Screen size
Distance from screen
Up to 22”
4 - 5ft
24 to 32” 6 - 9ft
39 to 46" 10 - 11ft
47 to 50" 12ft
55 to 60" 13ft
65 to 75" At least 14ft
Over 75" At least 20ft

Televisions with a screen type of 4K UHD provides a much more intimate viewing experience than the older resolution screen. As such, the most comfortable viewing distance is very much similar to the way we view films in the cinema – that’s 1.5 screen heights back. Translated to the home, this means that the recommended distance to view a 65 inch, 4K screen is five foot away from the sofa, although this may not be a practical option for many families. Therefore, look to secure the big screen to a suitable wall mount or television stand between six to eight foot away so you can make the most out of the available space in your living room.

Curved screens
Most of the benefits of curved displays come from being in the ‘sweet spot’: the right balance between distance and position. Here you can enjoy 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 screens improve side angles by bringing the corners of the screen back towards you so no matter where you are sitting, you’ll have the best possible viewing experience. For more advice watch our informational video below and see our guide on curved TVs for the best possible viewing experience.

HD vs 4K Ultra HD

In the UK, HD-ready means that 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

Full High Definition televisions display up to four times the quality of current analogue and digital broadcasts. Full HD gives you a higher screen resolution which means that it can give you more detail if you plug in a device which kicks out that kind of picture.

Some televisions will take a standard definition signal from a DVD player or the built-in digital tuner, and give it a HD "makeover" through a process referred to as upscaling. While this does make the picture better, the benefit of HD is appreciated fully when used in conjunction with a compatible source such as a Blu-ray player or games console.

What’s more, Full HD is currently being broadcast in a 1080p format. This format uses a ‘progressive’ scan which assumes a widescreen aspect ratio of 16:9, a screen resolution of 1920x1080. And as a result, picture detail looks sharper and more defined than 720p and 1080i, especially during fast motion. The 1080i format uses an ‘interlaced’ system which results in a slightly lower picture quality.

The difference

The best general indicator of what the difference is between HD Ready and Full HD is the picture quality. The picture resolution is made up of lines of pixels that display the picture - the greater the resolution, the higher the picture detail will be.

4K Ultra HD
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 are created with 8.3 million pixels – that’s four times the pixels of a Full HD screen. This means that you can sit closer to the screen or view on a larger television, without the picture looking pixelated.

4K Ultra HD is just a taste of what is around the corner in television world. The majority of big-budget films are now being shot in 4K and some television broadcasting companies, including the BBC, have been experimenting with 4K filming for some time now but are yet to broadcast. So in the meantime, streaming is the primary way to receive 4K content in our homes. Netflix has already launched its initial 4K offering, as has Amazon who announced their 4K service to Prime Instant Video users in December 2014. YouTube also plan to stream 4K content this year. You could even create and watch your own content with a 4K HD camcorder. This means that you can shoot in a 4K resolution and watch your footage in the same quality on an ultra-HD TV, when it is connected with a HDMI cable.

The resolution will really come into its own in delivering sports coverage over the next year or so. And while we wait for 4K content to arrive, Ultra HD TVs can still offer dramatic improvements in picture quality which can be enjoyed on the 4K screen because of upscaling capabilities. At the time of introduction to the market, 4K UHD screens were commonly large, over 70”, which was also reflected in the price. Thankfully though, not only have the prices fallen but so have the screen sizes which makes them a lot more manageable for the home. As manufacturers continue to use a variety of technologies to support a faster frame rate and improve colour and contrast, the larger screen sizes can come into play too to create a truly immersive cinematic experience.

If you want to connect your television to a Blu-ray player or games console then you’ll need a HDMI cable. These all-in-one cables carry sound and video signals in a much neater package than older component type cables. Generally speaking, the more that is spent on quality, the more quality signal is transmitted, so be sure to consider your options before purchasing.

SMART TV and media streaming

SMART TVs bring you the best of the web straight to your television screen by seamlessly streaming online content through your broadband connection. With no need for a PC, you can access a world of online video entertainment direct from the comfort of your sofa, via your TV screen and trusty remote control.

If you don't own a SMART TV already, you'll need a smart box and broadband connection. Once the network media player is plugged into your TV, friends and family can enjoy your favourite memories, tracks or movies not hunched around a computer.

Media streaming is set to become even easier with the advent 
of DLNA compatible products. DLNA (Digital Living Network Alliance) compatibility is the ability to access your photos, music and movies from your PC across your home network from a compatible device. For instance, you could play your friends the latest MP3 track you've just downloaded, even though your computer is upstairs in the spare bedroom.

Ways to use media streaming

  • Watch movies: stream favourite DVDs or downloaded movies from your PC to your big-screen TV in the living room.
  • Watch a family slideshow: access your entire digital photo library and view all your pictures on TV.
  • Listen to entire music playlists: free up the music on your PC and listen to it in the living room via the TV's sound system.
  • Watch videos from YouTube or catch up with the latest on demand services from BBC iPlayer and 4oD, all on your large screen.
  • Choose from a huge number of internet radio stations: access them via remote control from the comfort of your armchair.

Sound quality

With the advent of 3D TV and 4K UHD, and the resulting improvement in picture quality, sound has become increasingly important for an immersive viewing experience. Most TVs feature simple stereo sound or a system that produces a 'virtual' surround sound effect. With TVs getting slimmer and built-in speakers getting smaller - choosing the right sound system is more important than ever. Adding a sound bar or sound base will allow you to recreate those memorable cinematic experiences in your own living room.

A sound bar is for positioning in front of the television screen or even securing to a wall. Depending on the model, the sound bar will either have a wired or a wireless subwoofer, which enhances bass and depth to the sound quality. A soundbar with a wireless subwoofer has the added benefit of discreet storage which can be stowed away safely within your living room at ease.

A sound base is for positioning underneath the base of the television screen. These are ideal if space is limited or if you would prefer a more discrete sound enhancing option. The sound base has an integrated sub-woofer which replaces the built-in television sound with an enhancing quality, leveraging the wattage and power.

Discovering 3D

3D TVs bring entertainment to life before your eyes. By wearing specially designed 3D glasses, images are given added depth, making you feel as though you're in the middle of the action. Glasses-free 3D TVs have also started to appear, meaning that you can dispense with specs altogether, sit back and enjoy immersive 3D viewing in total comfort. 3D programming is available from Sky, presenting sports, movies and entertainment in all their glory. You can also enjoy all your favourite movies on a compatible 3D Blu-ray player.

3D TVs will allow you to watch both 3D and 2D video content as they use the same electronic video processing systems to display the images. You'll even be able to turn off the 3D effect in order to watch your programmes and films in 2D.

There are three types of 3D: Active, Passive and Glasses-Free (or 'auto-stereoscopic'). The former typically offers the greater 3D experience and uses glasses which have small LCD screens. They're typically heavier than passive glasses and will require charging after prolonged use. They're also more expensive than passive glasses, which are more lightweight and thus more comfortable for extended 3D viewing.

How does it work?

Active 3D works by sending two separate images of the same scene simultaneously, one intended for your right eye and one for your left. These full-size images occupy the entire screen and appear intermixed with one another, appearing blurred for viewers not wearing 3D glasses. When you don the glasses, you'll perceive these two images as a single 3D image, a process known as 'fusing' and the illusion of depth is created.

Passive 3D glasses block different kinds of light from each eye, creating the illusion of depth. For those who have experienced 3D films at your local cinema, this is passive 3D.

Glasses-free 3D requires the TV to project differing images to each eye which then merge to create a 3D effect. This is a similar technique used by the other two methods, but a special lens in the TV panel takes care of the glasses' job of fusing the images together.

What do I need?

To watch 3D in your home you'll require a 3D ready TV, a 3D source such as Sky 3D or a 3D compatible Blu-ray player3D glasses for your TV set and a compatible HDMI cable to transfer the 3D signal to your TV.
