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
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.
