Contrast is calculated by the difference between the brightest whites and darkest blacks of a display. This is measured in candelas per square meter (cd/m<sup>2</sup>) - a value called nits. Zero nits (completely black) is currently only possible on OLED displays, which completely turn off the pixels. Standard dynamic range (SDR) TVs produce 300 to 500 nits, while High Dynamic Range displays can reach thousands of nits. <ref name=”2”></ref> | Contrast is calculated by the difference between the brightest whites and darkest blacks of a display.

Technicolor has partnered with Phillips to develop a new format compatible with SDR displays that the companies say “will simplify HDR deployments for distributors who will be able to send one signal to all of their customers, regardless of which TV they have.” <ref name=”2”></ref> | Technicolor has partnered with Phillips to develop a new format compatible with SDR displays that the companies say “will simplify HDR deployments for distributors who will be able to send one signal to all of their customers, regardless of which TV they have.” <ref name=”2”></ref> | ||

An essential feature of virtual reality is the sense of immersion. There are several factors that contribute to an increase of it, and perceptual realism of the displayed images is one of the most important. <ref name=”4”></ref> | An essential feature of virtual reality is the sense of immersion.
