4K TV
The New 4K TV

New TV Trends
4K TV is the newest technology. 



LG 4K TV has four times the resolution of 1080p

What is 4K TV ?

The latest TV video standard you can expect to start experiencing in late 2012 and 2013 is called 4K, which promises an increase of four times the video sharpness of the current TV leader, 1080p (1920 x 1080 pixels or 1,080 rows of 1,920 dots each) video resolution. But 4K requires four times as much data. There is Quad Full HD (3,840 x 2,160 pixels) and also 4K/2K, sometimes called 4K x 2K (4,096 x 2,160 pixels). Only Quad HD conforms to the classic 16:9 ratio of current television screens.

Quad Full High Definition (QFHD), at 3840 x 2160 pixels, doubles the 1080p high-definition television standard in both the vertical and horizontal dimensions. 4K can refer to 3840 x 2160 pixels or 4096 x 2160 pixels.

Many questions come to mind regarding 4K such as the availability of 4K content. Is 4K really needed in the home? How much will 4K TVs cost? Toshiba and Sharp are selling 55- and 60-inch 4K televisions in Japan, with price tags topping $10,000. How can 4K data streams be sent over internet without staggering download times?

We have gone from video tape to Laser Disc to DVD to Blu-ray. Blu-ray is still trying to take over DVD. Many are still very satisfied with DVD. It has been over ten years since flat screen Plasma TVs arrived. We have 3D TV, Internet TV, larger and thinner TV screens, wireless and better and better display technology such as OLED. 4K is the latest trend in the march forward with 8K not far behind. Some cutting edge types will adopt 4K while many will begin to experience TV technology overload. 


4K video resolution 1920 plus 1920 = 3840 and 1080 plus 1080 = 2160

Sharp already has a 60-inch 4K television with 3840 x 2160, or what’s known as QFHD (Quad Full High Definition). It’s a 16:9 aspect ratio that brings four times the resolution of Full HD 1920 x 1080. That’s 8,294,400 pixels compared to 2,073,600 pixels. QFHD is called 4K but it technically doesn’t hit the 4000 pixel count.
