Nit

 

the name of a unit of luminance previously included in the International System of Units (SI). The unit is equal to 1 (candle/m2). It was accepted by the International Commission on Illumination in 1951 and by the All-Union State Standard (GOST) 7932–56 on light units but was not approved by the General Conference on Weights and Measures. The international symbol is nt; 1 nt = 10-4 candle/cm2 = 9.95 × 10-5 stilb = 3.13 × 10-4 lambert. The term “nit” is not included in new standards of units.

nit

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 Although, LCD screens range from 200 to 500 nits, our outdated TV standard is 100 nits, which was set in the days when rare earth phosphors were used in cathode ray tubes (CRTs).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 Dolby HDR and LED TV.

Nit ratings are not commonly advertised; however, in 2014, Lenovo published them for its W540 ThinkPad laptop. One model had a common 1920x1080 resolution at 220 nits, and another had a high-resolution 2880x1620 screen at 300 nits. See stilb and candela.
