Comparison of 4K Ultra HD and other common 16:9 aspect ratio monitor resolutions.
This article refers to the 3840x2160 Ultra-HD resolution of the 16:9 aspect ratio. For the 21:9 ultra-widescreen standard, see Ultra-widescreen.
Key points
- 4K Ultra HD (also 4K UHD or simply UHD) refers to a new standard of screen resolution at 3840 pixels wide and 2160 pixels tall.
- It is important to note that 4K refers to the horizontal resolution, in contrast to others, such as '1080p', which refer to the vertical resolution. 4K Ultra HD is therefore also known as '2160p'.[1]
