Monitors come with a long list of specifications, but not many know what the figures represent.
Response Time Response time is measured in two ways; it is the duration taken for a pixel to switch from black-to-whiteto-black, or from grey-to-grey. Typical response times for most monitors range from 8-16ms for black-to-whiteto-black, or 2-8ms for grey-to-grey. Nowadays, response times are usually referred to in grey-to-grey terms.
Brightness Brightness is a measure of the luminance (or luminous intensity) of the monitor per square meter. As the name suggests, it gives a rough gauge of how bright a monitor screen will be. While monitors today have brightness ratings ranging from 200 cd/m2 to 300 cd/m2, it is advised to calibrate your monitor to a more moderate brightness of 120 cd/m2.
Contrast Ratio Contrast Ratio is a ratio of the luminance of the brightest white, and the luminance of the blackest black a monitor can reproduce. When measured accurately, it can give a good idea of a screen’s capabilities. However, with no standard methodology to measure contrast ratio, manufacturers have converted this specification into a marketing gimmick.
