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.
