Medieval Latin gamma 'G' + ut 'lowest note'
1520s, originally, "lowest note in the medieval musical scale," in the system of notation devised by Guido d'Arezzo, contraction of Medieval Latin gamma ut, from gamma, the Greek letter, indicating a note below A, + ut, the low note on the six-note musical scale that took names from corresponding syllables in a Latin hymn for St. John the Baptist's Day:
Ut queant laxis resonare fibrisetc. Gamut came to be used for "the whole musical scale;" the figurative sense of "entire scale or range" of anything is first recorded 1620s. When the modern octave scale was set early 16c., si was added, changed to ti in Britain and U.S. to keep the syllables as different from each other as possible. Ut later was replaced by more sonorous do (n.). Cf. also solmisation.

The gamut of a monitor is the set of colours it can display. There are some colours which can't be made up of a mixture of red, green and blue phosphor emissions and so can't be displayed by any monitor.
in music, the full range of pitches in a musical system; also, the compass of a particular instrument or voice. The word originated with the medieval monk Guido of Arezzo (d. 1050) to identify his system of solmization, i.e., of using syllables to denote musical tones in a scale. Thus, to render in syllables the six tones of the hexatonic scale that prevailed, Guido started with the lowest tone recognized in medieval music theory, the second G below middle C, or gamma. For this note he selected the syllable ut from the hymn "Ut queant laxis" and for the ascending tones used the syllables re, mi, fa, sol, and la. Since Guido and his successors conceived musical theory in terms of overlapping hexachords rather than the diatonic scale, the syllable ut could represent any of the three pitches capable of sustaining the overlapping hexachords that made up the system; these were C, F, and G. While ut might vary, there was only one gamma-ut.
