A measurement of the brightness of light. One nit is equal to one candela (one candlepower) per square meter (1cd/m2
). The sun at noon is rated at 1.6 billion nits. Although, LCD screens range from 200 to 500 nits, our outdated TV standard is 100 nits, which was set in the days when rare earth phosphors were used in cathode ray tubes (CRTs). Various high dynamic range (HDR) technologies, such as Dolby Vision, yield 4,000 nits and above on LCD TVs. See stilb
