The nit (symbol: nt) is a non-SI name also used for this unit (1 nt = 1 cd/m 2). [1] The term nit is believed to come from the Latin word nitēre, "to shine". [2] As a measure of light emitted per unit area, this unit is frequently used to specify the brightness of a display device. The sRGB spec for monitors targets 80 cd/m 2. [3]
High brightness sunlight readable monitors are typically used commercially in kiosks, vending systems, pipeline inspection systems, outdoor digital signage and advertising, in sports stadiums, in military vehicles, on ships for navigation systems, on bus and train platforms, and much more.
Brightness is the term for the subjective impression of the objective luminance measurement standard (see Objectivity (science) § Objectivity in measurement for the importance of this contrast). The SI unit for luminance is candela per square metre (cd/m 2). A non-SI term for the same unit is the nit.
The highlights—the brightest parts of an image—can be brighter, more colorful, and more detailed. [2] The larger capacity for brightness can be used to increase the brightness of small areas without increasing the overall image's brightness, resulting in, for example, bright reflections from shiny objects, bright stars in a dark night scene, and bright and colorful light-emissive objects ...

HDR10 is supported by a wide variety of companies, which include monitor and TV manufacturers such as Dell, LG, Samsung, Sharp, VU, Sony, and Vizio, [8] [9] as well as Sony Interactive Entertainment, Microsoft and Apple which support HDR10 on their PlayStation 4, Xbox One video game console and Apple TV platforms, respectively.
luminance is the photometric brightness of an object (in units of cd/m 2), taking into account the wavelength-dependent sensitivity of the human eye (the photopic curve); relative luminance is the luminance relative to a white level, used in a color-space encoding; luma is the encoded video brightness signal, i.e., similar to the signal voltage ...
