What is 4K UltraHD in Samsung Smart TV's?
4K UHD is a resolution of 3840 pixels × 2160 pixels (8.3 megapixels, aspect ratio 16:9). It is one of the two resolutions of Samsung ultra high definition television. 4K UHD has twice the horizontal and vertical resolution of the 1080p HDTV format, with four times (2 x 2) as many pixels overall.
(Resolution comparison between SD, FHD and UHD)
The term 4K refers to the horizontal resolution (instead of the vertical) of these formats, which are all on the order of approx 4,000 pixels.
Example: Let's take FHD (Full High Definition) resolution which is (1920 x 1080).
Width: 1920 × 2 = 3840 (horizontal resolution multiplied by 2).
Height: 1080 × 2 = 2160 (vertical resolution multiplied by 2).
Hence, the resolution for 4K UHD is (3840 x 2160).
NOTE: You will see UHD in your TV screen instead of 4K.
