About monitor calibration settingsMonitor calibration involves adjusting video settings, which may be unfamiliar to you. A monitor profile uses these settings to precisely describe how your monitor reproduces color. Brightness and contrast The overall level and range, respectively, of display intensity. These parameters work just as they do on a television. Adobe Gamma helps you set an optimum brightness and contrast range for calibration. Gamma The brightness of the midtone values. The values produced by a monitor from black to white are nonlinear--if you graph the values, they form a curve, not a straight line. Gamma defines the value of that curve at halfway between black and white. Gamma adjustment compensates for the nonlinear tonal reproduction of output devices such as monitor tubes. Phosphors The substance that monitors use to emit light. Different phosphors have different color characteristics. White point The RGB coordinates at which red, green, and blue phosphors at full intensity create white. |
