Ultra HD or UHD shows images in 3840 x 2160 resolution, While the so-called 4K actually has 4096 pixels horizontally across the screen and 2160 pixels vertically. Put it in another way, it displays contents at width reaching approximately 4000p. However, the touch panel suppliers or retailers prefer to advertise their products as 4K UHD Screen
. So you need to note that “4K UHD” or “4K” virtually refers to the resolution of 3840 x 2160, which has gone completely mainstream in the market.
