TV Buying Guide

Treating yourself to a new TV? Or maybe you’re long overdue an upgrade? Whatever your reasons, there’s a lot of new tech and features you’ll need to wrap your head around, and our handy buying guide will help you do just that.

How to know which size is right for you 

Size is important. Your TV needs to suit your room and viewing needs, whether that’s a basic smaller model for your kitchen, or a giant screen with the latest tech for your living room. Here are a few things to consider.

TV sizes have changed a lot. They now have much thinner bezels, meaning you get more screen size for your money. And the latest tech means TVs are getting thinner and thinner, so even the biggest screens aren’t too imposing in your home.

TVs are measured diagonally, from corner to corner, and there’s a handy formula you can use to work out the size you need.

Measure the distance between where your TV will be and where you’ll be sitting in inches. Divide this number by two for your recommended screen size. This formula can be helpful but isn’t vital. You should always choose the size that feels right for you.

Big really is better when it comes to screen size. And we recommend sizing up when choosing your next TV – Most of the best tech only comes in models that are 40” or bigger. Plus, a bigger screen means you’ll be future-proofing your set-up.

Did you know? UK households have seen a 50% increase in TV size since 2010.

Smart TV

What is a smart TV?

Most TVs are smart now, which means they can connect to your WiFi. This lets you enjoy all the entertainment that the internet has to offer, such as subscription based services like Netflix and Prime, and catch-up classics like iPlayer. Smart TVs also don’t need an additional set top box to connect to your WiFi, because everything’s built in. When you hook up the TV for the first time, usually as you go through the set-up process, you’ll be asked to connect to the internet. Make sure you have any passwords on hand to make it quick and easy.

What can I watch?

The main benefit of a smart TV is naturally the amount of entertainment on offer. With different streaming platforms popping up left, right and centre, there’s bucket loads.

Free on-demand apps

You’ll find all your classic free catch-up and on demand apps such as BBC iPlayer for the best of British drama, and ITV Hub for all those great game shows and talked about reality TV. Not to mention the great entertainment on the likes of All4, My5 and Freeview. Learn more about Freeview Play here.

Subscription based streaming services

Looking for a bit more excitement and adventure? There’s a ton of subscription based streaming services available serving up the best in original films and binge worthy series. You’ve got your go to’s such as Netflix, Amazon Prime, Now TV and Disney +. But there’s also more independent services like BFI Player or MUBI, if you’re looking for that uncut gem.

Smart platforms

Different manufacturers use different smart platforms to let you sift through all the great entertainment the internet has to offer. You have WebOS with LG TVs, Tizen for Samsung, Android TV for Sony and even Apple TV which comes with its own line-up of original shows. They all look and work a little differently, but they’re a more user-friendly way for you to flick through the apps and services you love.

What technology are smart TVs compatible with?

Are you riding the smart home trend? Or maybe you’re thinking about getting into it. Not to worry. A lot of TVs now are compatible with your other smart devices.


Some TVs can connect to your Amazon Alexa device, meaning you can change the volume, select different apps and choose the stuff you want to watch with your voice. Even better, some models come with Alexa built-in, so you can enjoy the benefits of voice control without having to own an additional smart device.

Google Assistant

Like Alexa, some TVs can hook up to your Google Assistant smart device. So, you can put that remote down and impress your family with hands free control next time movie night comes around.

Picture Resolution

4K Explained

4K is one of the most common screen resolutions in TVs. With four times more pixels that a HD TV, 4K screens display your favourite films and shows with unbelievable detail. Plus, all the top streaming platforms such as Netflix, Amazon Prime and Disney + come with a range of 4K content for you to enjoy. If you’re looking for a TV for now and the future, a 4K model is a must.

Picture Quality

Improved colour and contrast with HDR

Screen tech, resolution and now picture quality? We know, there’s a lot to take in when picking out that new TV. Let us take you through some great features that’ll completely enhance the stuff you see on screen.

High Dynamic Range (HDR)

TVs with HDR tech display a wider range of colours with better contrast. This clever use of colour creates vivid and lifelike images, making it perfect for throwing yourself into those nature docs or that edge-of-your-seat sporting event. Most HDR TVs also pack in a 4K Ultra HD resolution. The two work together to bring you incredible visuals that'll transform your home viewing.

Shop TVs with HDR


HDR10+ takes high dynamic range technology up a notch, displaying that sci-fi film or football match in even more colour and detail. HDR10+ adapts during each scene or sequence of the content you watch, meaning it’s constantly improving the range of colours and details throughout. This means you know you’re watching the best possible version of the entertainment you love.

Dolby Vision

Dolby Vision makes sure you’re always watching your favourite films with the best possible quality. It works in a similar way to HDR10+ by adapting the visuals scene by scene, so what you see on screen is bursting with vivid colours and details.

Sound Quality

Often the area that’s overlooked when picking out that new TV, but no film experience is complete without great sound. With modern TVs being so thin, the sound can sometimes be an issue. So, here are a couple of features that are guaranteed to make your walls shake.

Dolby Atmos

Immerse yourself in the sound of your favourite entertainment with Dolby Atmos. This tech recreates the audio from that pulsating sci-fi or that rich period drama in 3D for that full surround sound experience.


No home cinema set-up is complete without a good soundbar. They’ll take your movies and shows to the next level with ground shaking sound. We’d recommend choosing a model with an additional sub-woofer – these chunky boxes will add the bass to those action extravaganzas for that true cinematic experience.
