New Year's Resolution (4k)

A pixel is the smallest unit of a digital image or graphic that can be displayed and represented on a display.

Resolution is the image quality displayed on a screen.

For shopping purposes, 4K, also known as Ultra HD (High Definition), or UHD, refers to a resolution of 3,840 x 2,160 pixels. That’s four times the 1,920 x 1,080 pixels found in an original full HD TV. 

More pixels means a clearer, better defined, more life-like picture.  A common description is as if looking through a window rather than watching TV.

TV delivered through your aerial or satellite box is transmitted in a lower resolution.  Your new UHD TV will use a computer chip to use the 4K pixel count to improve the picture.  So buying a 4K TV will almost definitely improve your viewing.

For the full UHD experience you will need a TV provider that sends content in 4K.  The most important here are Netflix and Amazon.  These are provided via an internet connection.

It’s worth considering that you will need a minimum of 15 mbps internet speed (with no other computers, tablets, phones using at the same time), otherwise the transmission will drop to a lower resolution.  To be absolutely sure a fibre internet service is recommended. 

BT has sports content and the SkyQ 2TB box has sports, movies and other content available.  These boxes need connecting to the TV with a HDMI 2.0 cable for best results. 

All of these services require a subscription payment of some kind.

So your simple technical guide for 4K:

  1. 4K, Ultra HD or UHD are the same for the purposes of buying a television;
  2. You will see an improved picture regardless of the type of TV you watch;
  3. However, for a full 4K experience you will need either a TV box subscription service with add ons;
  4. Or a fast internet connection with a streaming service like Netflix or Amazon;
  5. Any new 4K boxes need connecting with a HDMI 2.0 cable.

Make your resolution a new one this year.
