4K HDR – Taking Picture Quality to the Next Level

Posted on 5th December 2016

If you’ve been thinking about getting yourself a 4K/Ultra HD TV, there is no doubt at all that you have met some confusing information along the way. Not to mention the huge number of acronyms surrounding the advanced features available in the new range of Televisions. It can all be a little confusing, and there is no wonder a lot of uncertainty and debate surrounds TV picture standards.

4K refers to the approximate number of pixels that display across your TV or display screen horizontally. This being 3840, but manufacturers round this up to 4000, called 4K resolution (current HD Televisions are 1920 pixels, around “2K resolution”). We hope that this information will help to clarify the difference between the technologies and why HDR is the right choice for you if you want to get the best viewing experience possible.

What is HDR?

HDR (High Dynamic Range) is the new picture standard for Ultra High Definition TVs that has brought image quality that one step closer to the real thing. HDR is about the expression of images and is a result of the depth of contrast between light and dark colours that a Television screen can produce. The TV comes to life with incredible clarity and detail, brighter objects and richer, more vibrant colours.


HDR picture standards for TV support twice the number of visible colours, this being over a billion!
HDR also supports much higher brightness levels and contrast ratio (more than 10,000:1). The picture will have less noticeable gradients between shades of colours.

Not all TVs are HDR TVs

The number of manufacturers that are releasing 4K Ultra HD TVs is increasing substantially, mainly due to their popularity. But not all 4K TVs are the same, some are able to play Ultra HD videos but cannot process HDR content. To be classed as a 4K TV it only has to include a certain number of pixels, but to really get the best viewing experience possible, your TV must have HDR imaging capabilities so that it can enhance and optimise everything that you watch.

4K Upscaling

The amount of Full 4K UHD content available for the consumer has only just started to take off now. But what happens when you are not watching 4K/HDR videos? The answer is called 4K Upscaling. Ultra HD TVs will upscale content that is non-4K to the highest resolution possible in order to maximise image quality.

How to watch incredible 4K Movies and TV Programmes

You can watch movies and TV shows in immersive 4K Ultra HD through 4K-enabled Blu-Ray Discs and SkyQ, but also through applications like Netflix, Amazon Prime Video, Youtube, Vimeo, Plex, Kodi and more.
