Televisions

TV screen size is measured diagonally from the bottom left corner to the top right. Use the same method to measure how much space you have, then shop by screen size.

A smart TV has catch-up and on-demand streaming services built-in, so you don't need any extras sticks or boxes. Some also let you use social media, Spotify and games.

Want a better listening experience than your in-built TV speaker? Look out for sound bars and other audio systems with surround sound, clear voice tech and object tracking.

4K Ultra HD is the name of the screen resolution four times clearer than a Full HD TV. It delivers a cinema quality picture, with crisp images and accurate colours.
