Blue Only / Mono

Red and Green channels are not used and only Blue or Monochrome channel is used to display the screen. This function is used to adjust the color tones (tones and saturation) of the screen using the SMPTE Color Bar. For example, after displaying the Blue channel, adjust the Color (or Saturation) and Tint (or Hue) so that the original Magenta and Cyan are of the same brightness, and the original Gray and Blue are of the same brightness.
