A method of calibrating a flat panel display, comprising the steps of: a) providing the flat panel display having an overall and individual video signal channel adjustment for both gain and offset and an adjustment to provide a white point for the display, the white point including color temperature, chromaticity and luminance level; b) displaying a first target using a low-level code value for each video signal channel of the flat panel display; c) sensing the luminance level of the displayed first target and measuring the RGB values; d) comparing the measured RGB values to a first predetermined aim value representing a luminance level at least 3 decades lower than a maximum luminance level; e) adjusting, if the first target is not equal to the first aim value, the gain and offset of the flat panel display so that the sensed luminance level matches the first predetermined aim value; f) displaying, if the first target is equal to the first aim value or following step e), a second target using intermediate code values for each video signal channel of the flat panel display; g) sensing the luminance level and chromaticities of the displayed second target; h) comparing the luminance level and chromaticities of the displayed second target to a second predetermined aim value representing an intermediate luminance level; i) adjusting, if the second target is not equal to the second aim value, the individual video signal channel gains and offsets so that the luminance level matches the second predetermined aim value and the chromaticities match a first set of predetermined chromaticities that represent a desired white point; j) displaying, if the second target is equal to the second aim value, a third target using maximum code values for each video signal channel of the flat panel display; k) sensing the luminance level and chromaticities of the displayed third target; l) comparing the luminance level and chromaticities of the displayed third target to a third predetermined aim value representing the maximum luminance level, m) adjusting, if the third target is not equal to the third aim value, the individual video signal channel gains and offsets so that the luminance level matches the third predetermined aim value, and that both the maximum luminance level and the chromaticities match the first set of predetermined chromaticities; and n) repeating steps f) through m) a number of times until the third target is equal to the third aim value. a) providing the flat panel display having an overall and individual video signal channel adjustment for both gain and offset and an adjustment to provide a white point for the display, the white point including color temperature, chromaticity and luminance level; b) displaying a first target using a low-level code value for each video signal channel of the flat panel display; c) sensing the luminance level of the displayed first target and measuring the RGB values; d) comparing the measured RGB values to a first predetermined aim value representing a luminance level at least 3 decades lower than a maximum luminance level; e) adjusting, if the first target is not equal to the first aim value, the gain and offset of the flat panel display so that the sensed luminance level matches the first predetermined aim value; f) displaying, if the first target is equal to the first aim value or following step e), a second target using intermediate code values for each video signal channel of the flat panel display; g) sensing the luminance level and chromaticities of the displayed second target; h) comparing the luminance level and chromaticities of the displayed second target to a second predetermined aim value representing an intermediate luminance level; i) adjusting, if the second target is not equal to the second aim value, the individual video signal channel gains and offsets so that the luminance level matches the second predetermined aim value and the chromaticities match a first set of predetermined chromaticities that represent a desired white point; j) displaying, if the second target is equal to the second aim value, a third target using maximum code values for each video signal channel of the flat panel display; k) sensing the luminance level and chromaticities of the displayed third target; l) comparing the luminance level and chromaticities of the displayed third target to a third predetermined aim value representing the maximum luminance level, m) adjusting, if the third target is not equal to the third aim value, the individual video signal channel gains and offsets so that the luminance level matches the third predetermined aim value, and that both the maximum luminance level and the chromaticities match the first set of predetermined chromaticities; and n) repeating steps f) through m) a number of times until the third target is equal to the third aim value.
