UHD (Ultra High Definition) and 4K are often considered synonymous, representing a resolution standard with a significant increase in pixel count compared to Full HD, i.e., 1080p. However, UHD and 4K have come to mean the same thing for the average consumer and are used interchangeably, particularly regarding televisions and consumer media content. Let us find out, UHD vs 4K which is better and which one to choose.
What is UHD?
UHD, or Ultra High Definition, is a broadcast standard for consumer display. UHD enables you to have a high-quality picture. It quadruples the Full HD resolution by four times to 3840 x 2160. It is used in TV advertisements primarily as most modern devices are equipped with UHD capabilities, ensuring an immersive viewing experience.
What is 4K?
If you wonder what is the resolution of 4K, you must know that 4K originally stemmed from professional production and cinema standards. It has a video resolution of 4096 x 2160, a bit wider than UHD. 4K is generally used in the consumer market and has a horizontal resolution of approximately 4,000 pixels. In 4K, ‘K’ stands for kilo, which means a thousand.
Difference Between 4K and UHD
There is not much difference in UHD vs 4K. These terms differ solely on the market. Vertical markets may separate them with different resolutions. However, in the display market, both 4K and UHD have the same resolution, i.e., 3840 x 2160.
Due to the difference in projectors, the digital cinema differentiates between 4K and UHD. Typically, 4K has a different resolution for the digital cinema market, like 4096 x 2160, and is 256 pixels wider than available UHD options in this market.
What Should You Choose: UHD or 4K?
It does not matter which one you opt for in a bid of 4K UHD vs 4K HDR. Whether you choose 4K or HDR, both offer the same resolutions for the digital market. However, the main difference in resolutions appears in the cinema industry. It depends on the directors and producers to choose one between the two. However, as a consumer, you can blindly pick any.
While major OTT platforms like Amazon Prime, Netflix, Hulu, etc., offer their on-demand videos in 4K, there may be a limit to what can be consumed in 4K. So you would not have a 4K viewing experience at all times.
