4K Ultra HD TVs are unique as they have the ability to make today's content appear better than it ever has. They have powerful, built-in processors that can upscale content up to four times the resolution of Full HD picture quality. Trusted brands such as Samsung, Sony, LG and Panasonic offer this benefit to deliver vibrant colour, vivid contrast and incredible depth to regular Full HD content.

It's worth noting, not all 4K UHD TVs can achieve high quality 4K upscaling. See the Key Things to Look For section for helpful tips.

Types of 4k content

The sound you get from your TV should be great, but the reality is that the demand for better picture quality and thinner screens has overtaken the sound quality your TV can produce on its own. Many manufacturers now recommend partnering your TV with a sound bar, home cinema system or soundstage for the ultimate all round experience.

  • 4K video streaming - You can enjoy your 4K content on the Netflix UHD streaming service, as well as on your Amazon Fire 4K Smart TV box.
  • Mastered in 4K Blu-ray - Watch the latest 4K Blu-ray DVD releases on a Blu-ray player with 4K upscaling, specifically designed to create a stunning picture.
  • 4K personal content - You can create your own 4K movies thanks to cameras and camcorders that are able to record video in 4K, including the GoPro HERO4 and Panasonic FZ1000 Bridge camera.
  • 4K computing - Computers and laptops with 4K graphics cards are becoming available. 4K connections such as HDMI 2.0 on these devices allow you to connect to a compatible 4K UHD TV.
  • 4K internet browsing - 4K browsing on your Smart TV is incredible, especially when using apps such as Google Maps or YouTube - see you favourite personalities and clips like you've never experienced before.
  • 4K broadcast - It's happened. 4K channels have launched. BT Sport Ultra HD broadcasts the beautiful game in beautiful 4K Ultra HD - the first of its kind in Europe. You can expect much more of this, with the first 4K BBC channels expected to be delivered in early 2016.

Key points to look out for

Having a TV with a 4K UHD pixel count does not, on its own, guarantee a great 4K experience. To get the very best experience you need to check that the TV is future-ready and has the following technologies built in:

  • HDMI 2.0 - This is a connection at the back of the TV. HDMI 2.0 supports Ultra HD video up to 60 fps and will ensure that the TV is compatible with future sources of secondary content such as 4K UHD set top boxes, Blu-ray players and 4k laptops. If the TV does not have HDMI 2.0 it will not show a picture from these devices.
  • Upscaling processing power - To enjoy your favourite shows and Blu-ray discs in improved detail and clarity, check that the 4K television has the ability to upscale your content effectively. Trusted brands including Samsung, Sony, Panasonic and LG all have state-of-the-art processing engines to ensure you get a great picture quality with no blur and pixilation.
  • High Efficiency Video Coding HEVC H.265 - A techy sounding name but put simply this is a new video compression format used to provide UHD content through streaming services most commonly through the internet. Netflix use this format to supply its 4K streaming content. If your 4K TV has Netflix built-in but does not have HEVC H.265 you will not be able to stream their 4K UHD content.
