So how large should you go? TVs are measured by their visible screen size - diagonally across the screen from one corner to the other, in inches. All our TVs have a 16:9 ratio so you see the whole widescreen picture.

We have a great range of sizes from 15in to a huge 70in+ TV screen. The most important thing is to think about the size of the room, in which you'll be watching your chosen TV, (you wouldn't want to squash a massive screen into a room where space is tight, after all). Just check our handy chart, it'll show the right TV to match the distance you sit from the screen.

Smart TV, also known as connected TV is a TV or set-top box with built in internal features, connecting up technology between smart phones, tablets, computers, TV sets and set - top boxes. Not only can you watch normal TV programmes but you can also enjoy online interactive media, Internet TV, over-the-top content, as well as on-demand streaming media, and home networking access.

The same goes with video calls - just plug in a webcam and you can make free Skype-to-Skype video calls anywhere in the world (You'll need an Ethernet or wireless connection to your broadband hub).

Some Smart TVs have a built-in internet browser so you can use your TV screen to search and shop from all your favourite websites without having to turn on your PC or laptop. It's the easiest way of getting the best of the web from the latest fashions to picking your holidays on the big screen. Look out for a smart TV with a dedicated web browser and you can do all this and more!
