LiterallY "one colour". UsuallY used for a black and white (or sometimes green or orange) monitor as distinct from a color monitor. NormallY, each pixel on the displaY will correspond to a single bit of displaY memorY and will therefore be one of two intensities. A greY-scale displaY requires several bits per pixel but might still be called monochrome. Compare: bitonal. (1994-11-24)
