4K Ultra-High Definition Explained

TV technology has gone through many changes over time. We started out with CRT TV sets, Tube TVs as they were called, and moved on to slim style plasma screens. Then came LCD where everything slimmed down further. LED screen technology made a hit and contrast levels skyrocketed allowing our TVs to go into true high definition. We have a new player on the field in OLED which is currently one of the highest display standards.

Now we are looking toward Ultra HD or 4K resolutions which offer four times the picture detail of today's HD televisions. Samsung, Sony, LG and Panasonic have all been showing off sets at the Consumer Electronics Show in Las Vegas which just passed in January.

What is Ultra HD/4K?

The Ultra HD format is 3840x2160 pixels in resolution compared to 1080p which is 1920x1080. This means it has four times the amount of detail as HD and eight times as much detail as standard definition! The technology is based on the Ultra HD standard used for projecting movies in theaters, and it's not just about the higher resolution – in the future Ultra HD will also support much higher frame rates to allow for smoother motion in video footage.

What are its advantages?

You will see amazing amounts of detail. The fractal patterns on leaves in a gardening show, individual faces in the crowd and on the court during March Madness. These details would be lost at a lower picture resolution. The difference is because the higher pixel count of a 4k screen allows for a more natural representation of the picture, with smoother outlines for distinct objects and added detail in the image.

Do you need Ultra HD?

If you are looking for the most life-like viewing experience. Ultra HD shows a real benefit to picture quality. Over the last 12 months prices for Ultra HD 4K televisions have fallen a significant amount, making this a great time to buy. There has been a large change for TV viewers since the advent of High definition. Ultra HD is going to make an even bigger splash in the market. Upgrading your TV to this new format will enhance your entertainment time and for sports fans it is a must-have.
