Here's an easy guide to what 4K means...

4K, Ultra HD and UHD are all different names for the same type of TV screen. 4K refers to the number of pixels on your TV screen – or the “image resolution” The pixels are the tiny dots of colour that make up the image you see on your telly. A pixellated image is one where the pixels are really obvious, because there aren’t many.

But images with lots of pixels – like a 4K movie – generally look sharper and clearer A true 4K screen has 4096 x 2160 pixels. That means on your TV screen there are 3840 pixels across, and 2160 pixels vertically. That’s roughly 8.

3 million pixels on the display in total 4K gets it’s name because it’s got four times the number of pixels as a standard Full HD TV Full HD (or 1080p) screens have 1920 pixels across, and 1080 pixels going upwards – for around two million pixels in total. So 4K just means your TV has many more pixels on the screen compared to a more common Full HD display Ultra HD, or UHD, is basically the same as 4K. If you buy a UHD telly in a shop, you’ll be able to watch 4K content on it with no bother But there is a small difference.

Almost every TV you ever buy has an aspect ratio of 16:9. That means for every 16 pixels horizontally, there are 9 vertically True 4K footage doesn’t quite fit in with that ratio, so you won’t often find TVs with 4096 x 2160 pixels. Instead, to fit with the 16:9 ratio, most 4K TVs will have 3840 x 2160 pixels instead If it doesn’t make sense, grab a calculator and divide 2160 by 9.

Then multiply it by 16, and you’ll get 3840. That’s the aspect ratio working its magic. So when you see an Ultra HD TV, it just means it’s a 4K image with slightly fewer vertical pixels If you try watching a 4K video on a non-4K TV, the video will still play – but it won’t be in 4K quality.

To watch a 4K video in 4K quality, you’ll need to fork out for a 4K TV. Similarly, if you’re watching standard or HD footage on a 4K TV, it won’t magically become 4K quality Some TVs promise “4K upscaling”, which converts your standard or HD footage to near-4K quality. This works by using software to guess what colours would fill the extra empty pixels missing in HD footage, and then filling them in.

This creates a 4K-like effect, but it’s not true 4K.
