Color Calibration

Saturation

  • Point the color analyzer or light meter towards the screen and display a 100% white test pattern.
  • Measure the Y value (luminance) of white.
  • Display a 100% Red test pattern, and measure the Y value here as well.
  • You will notice that as you move the Color control up and down, the Y value of Red increases and decreases, but white stays the same.
  • Set the color control at the point where Red measures closest to 21% of the white reading.
