What do you need to consider when choosing your TV?

Our new range of Android TV powered models deliver stunning details for that truly amazing experience. With unlimited access of entertainment through the use of Google Play, the power of Voice Control, built-in Chromecast, superior sound, brilliant UHD picture quality and so much more, we bring you the features you deserve into one phenomenal TV.

What resolution screen will you need? Full HD TV offers you a 1080p Full HD resolution, consisting of 1920 pixels x 1080 (1080p), which can be up to 5x sharper than a normal TV. Ultra HD TV has 2160 pixels x 1080 resolution and when you step up to 4K Ultra HD TV, you’re looking at 3840 pixels by 2160, offering you 4x the picture resolution of Full HD. This equates to around 8 million pixels which is 4x what a 1080p screen can display.

What size TV will best fit the room? From a simple 32 inch LED TV to a big screen suitable for a home theatre, you’ll need to consider how much space you have to work with. As a basic rule for most TV’s, you should be able to sit back about three times the height of the TV. When it comes to a 4K Ultra HD TV, a recommended distance is approximately 1.5x the height of the TV screen.

What is Smart TV? Quite simply, Smart TV, also known as Internet TV, is any TV that has internet connectivity. Some of the Apps TCL Smart TVs run are Netflix (provider of TV shows and movies accessible only online), HBBTV (Both standard and free to air services – Freeview) and Go Live (The ability to stream international content from around the world).
