4K ultra high definition is approximately how many times the resolution of full HD?

Two times
Three times
Four times
Five times

The correct answer is: Four times

4K Ultra High Definition (UHD) is considered to have a resolution of 3840 x 2160 pixels, while Full HD is defined as 1920 x 1080 pixels. To understand the relationship between these two resolutions, you can look at the number of total pixels in each. Full HD has a resolution of approximately 2 million pixels (2,073,600 pixels to be exact). In comparison, 4K UHD has about 8.3 million pixels (3,840 x 2,160 equals 8,294,400 pixels). When you calculate the ratio of 4K UHD pixels to Full HD pixels, you find that 8.3 million is roughly four times greater than 2 million. This means that 4K UHD provides significantly more detail and clarity compared to Full HD, which is why it is referred to as being approximately four times the resolution of Full HD. The increase in pixel count leads to sharper images and improved viewing experiences, especially on larger screens.
