Now let’s get started.

HD vs. UHD

HD (High Definition)

High Definition, or short for HD, refers to videos that has more than 720 horizontal lines. The minimum resolution of a HD video is 1,280 x 720 (1,280 vertical lines and 720 horizontal lines), hence “720p”. It includes totally 921,600 pixels. There is also a term called Full HD, which features a resolution of 1,920 x 1,080, and also is known as 1080p. In recent years, it has become the industry standard, and many television broadcasts, movies and video games are made in 1080p high definition. HD video comes with a 16:9 aspect ratio.

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. UHD to 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.

The significant difference between HD and UHD is the resolution. Considering the pixel number, UHD means overall enhanced viewing experience. The video image of UHD would be much clearer, sharper, and crisper than HD. Once UHD TV was on the edge of the market due to its high price, but in the last few years, the price of UHD TV drops to a reasonable level, and even people who are careful about spending could afford it. To get the immersive viewing experience at home, you should buy a 4K UHD TV.
