To 4K TV or not to 4K TV?

It’s a case of caveat emptor on 4K TV right now.

NZ will see HDMI HDCP 2.2 later in the year but it is very important to note that very few manufacturers advertising 4K on their screens are actually HDCP2.2 compliant, and those that are often only activate it on one port.  If you have brought the big 4K TV, it very well may not work with the new 4K content coming out (read: rugby world cup)

If you are in the market for a 4K TV, please check that it will support the new HD copy protection standards that 4K will run on.

If the answer yes and it is going on a wall, be sure that the back port is the one that gets the 2.2 love.

If you cant be bothered with all that click here and one of our friendly home automation technology consultants will arrange for a 4K HDCP 2.2 compliant TV to be delivered and installed ready for the HD wonderment that will be 4K!

Understanding 4K TV

4K resolution is 4096 pixels wide and 2160 pixels deep.  Multiply these two numbers and you will see that there is approximately 8.8 million pixels being transmitted!   Aspect ratio is calculated by dividing the width by the depth – 4096 divided by 2160 = 1:9:1 or 17:9.  This means that the image is 1.9 times wider than it is tall.   The TV’s that we use however are 16:9 and if we put a 17:9 image on a 16:9 display we get black bars on the top and bottom.  In order to correct this our industry has invented a new format called UHD or UltraHD.  The resolution for UHD is 16:9 or, 1.78 times the height.  This is still 8.3 million pixels!  However 7% of the full 4K resolution has been removed.  99% of products used  in consumer electronics use this format.
