As their names imply, 4K UHD has a considerably higher resolution than 1080P HD video.
4K resolution is exactly 3840 x 2160 pixels, whilst 1080P consists of 1920 x 1080 pixels.
This massive difference brings about some important advantages for 4K when one compares it to the quality of a 1080P video.
Can you tell the difference between 1080p and 4k?
In short, it depends. The difference between 1080p and 4K is undeniable in that a 4K screen is capable of displaying four times the number of pixels as a 1080p screen. From a distance, it is virtually impossible for someone to tell the difference in quality between a 1080p and 4K screen.
Does 1080p look better on a 4k TV?
Here’s the problem. Your 4K TV has a resolution of 3,840×2,160 pixels. Pretty much all cable, satellite, streaming, gaming, Blu-ray and other video content is 1,920×1,080 pixels (which is called 1080p and 1080i) or 1,280×720 (called 720p). All 4K resolution TVs have four times as many pixels as 1080p TVs.
Can the human eye see 4k resolution?
But even those standard HD sets, at the distance viewers regularly watch them, can be considered “retina” resolution. The number of pixels is quadrupled for 4K TVs, but experts say that in most cases, the human eye cannot even perceive the difference.
