What is 4K?
4K refers to a horizontal display resolution of approximately 4,000 pixels. The term generally refers to one of two high-definition resolutions: 3840×2160 (4K UHD) or 4096×2160 (DCI 4K).
4K is a display resolution of approximately 4000 horizontal pixels. It is called Quad HD because it has four times as many pixels as an HDTV.
The main advantage of 4K is that it offers a significantly higher level of detail than HD. This is especially noticeable when viewing images or videos containing many fine details, such as close-ups of people or nature scenes. In addition, 4K also offers a wider color gamut and higher dynamic range than HD, which results in more vibrant and realistic colors.
The main disadvantage of 4K is that it requires more processing power and storage space than HD. In addition, 4K displays are still relatively expensive, so they are not yet widely available.
4K is the future of high-definition video and is slowly becoming more common in consumer electronics. As prices continue to drop and more 4K content becomes available, this technology will likely eventually replace HD altogether.
What is UHD?
UHD, or Ultra High Definition, is a resolution standard in the consumer electronics market. It succeeded High Definition (HD) and Wide Quad eXtended Graphics Array (WQXGA).
UHD has a display resolution of approximately 3840 horizontal pixels. It is sometimes called Ultra HD or 4K 2160p because it has twice as many pixels as a 1080p TV.

What is the difference between 4K and UHD?
the difference between 4k and UHD is that 4K refers to a horizontal display resolution of approximately 4000 pixels, while UHD refers to a horizontal display resolution of approximately 3840 pixels.
4K is a display resolution of approximately 4000 horizontal pixels. It is called Quad HD because it has four times as many pixels as an HDTV. On the other hand, UHD has a display resolution of approximately 3840 horizontal pixels. It is sometimes called Ultra HD or 4K 2160p because it has twice as many pixels as a 1080p TV.

There are two main ways to achieve a 4K or UHD display: using a native 4K or UHD display or upscaling from a lower resolution. Native 4K or UHD displays have a pixel density that is high enough that the human eye cannot resolve the individual pixels at a normal viewing distance. Upscaling takes a lower resolution image and uses software to increase the number of pixels, resulting in a sharper image.
