UltraHD

UltraHD, also known as UHD or 4K resolution, refers to a digital video display resolution with a horizontal resolution of approximately 4,000 pixels. The most common UltraHD resolution is 3840 x 2160 pixels. This is four times the resolution of Full HD (1920 x 1080 pixels), offering significantly more detail and sharper images. The increased pixel count allows for finer textures, smoother gradients, and a more immersive viewing experience, especially on larger displays. UltraHD is often associated with other advanced display technologies such as High Dynamic Range (HDR), which expands the range of contrast and color, and wider color gamuts, providing more vibrant and lifelike colors. The adoption of UltraHD has been driven by advancements in display manufacturing, the availability of UltraHD content from streaming services and physical media like Ultra HD Blu-ray, and the increasing popularity of larger screen televisions. While the term "4K" is frequently used interchangeably with UltraHD, it technically refers to a cinema standard resolution of 4096 x 2160 pixels. In consumer electronics, 3840 x 2160 is the standard for UltraHD.
