What is 4K Ultra HD TV?

Having become used to buying Televisions with High Definition or HD resolution we are now seeing 4K televisions everywhere.  Technology has moved on and as TV screen sizes are becoming ever larger, increases in definition quality are needed to provide excellent viewing experiences. So, what is 4K Ultra HD TV and is it worth getting?

How does 4K compare to HD ?

Current HD resolution is known as 1080p and is made up of 1920 x 1080 pixels on a 16:9 aspect screen.  This equates to 2,073,600 (known as 2K) individual pixels lighting up your living room TV.

So multiply this by 2 and we arrive at 3840 x 2160 pixels equating to 8,294,400 individual pixels squeezed even more closely onto your screen and giving a much clearer and sharper image.

Why is it called 4K?

Because this Definition contains 4 times as many pixels as our current 2K standard.  It began life referred to as 4 x 2K and this was abbreviated to 4K.

More recently, the Consumer Electronics Association (CEA) has officially christened 4K as “UltraHD” – Ultra High Definition – and this is already being referred to as UHDTV.

Interestingly, Sony has retained the 4K moniker in their current product labelling whilst including the UltraHD name.

What do I need to know about 4K?

Whilst all the acronyms may be confusing, all you really need to know is that 4K or UltraHD has the capacity to deliver more depth and definition to your TV screen.

Like most things, the end result – or what you see – will depend on how several factors such as how the TV manufacturer implements the new standards, the quality of the media that is displayed on screen and the interface between the media source and the TV.

And the larger TV screen that you choose, the more likely you are to really appreciate the deeper quality that this new standard can deliver.
