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.

Key points to look out for

It takes more than a 4k UHD pixel count to guarantee a great 4k experience. To ensure that you get the best experience, check that the TV is future-ready and has the following technologies:

  • HDMI 2.0 - The HDMI 2.0 connection at the back of the TV supports Ultra HD video up to 60 fps, and will ensure that the TV is compatible with future sources of content such as Blu-ray players, 4K UHD set top boxes and 4k laptops. Your TV requires HDMI 2.0 to show a picture from these devices.
  • Upscaling processing power - If your 4K TV can effectively upscale content, you can enjoy your favourite shows and Blu-ray discs in ever better clarity and improved detail. UHD TVs from brands such as Samsung, Sony, Panasonic and LG include state-of-the-art processing engines to provide excellent picture quality without blur or 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.
