There is also a term called Full HD, which features a resolution of 1,920 x 1,080, and also is known as 1080p.

UHD (Ultra High Definition)UHD, the acronym of Ultra High Definition, is the next upgrade of HD. Some people call UHD as 4K, and though 4K and UHD are different technically, these two words can be used interchangeably. You can go to 4K vs. UHDto learn the detailed differences. 4K UHD is made up of 3,840 vertical lines and 2,160 horizontal lines, namely 8,294,400 pixels, which is four times as many as that in a Full HD 1080p video.

To get the immersive viewing experience at home, you should buy a 4K UHD TV.
