Intensity

Intensity species the luminance or “brightness” of white when displayed on the screen. The maximum Intensity value

of a display will depend on many factors, such as, the color temperature of the White Point selected, the type of monitor,

individual component tolerances, usage, and age of the display.

Intensity can be measured and specied in units of either Candelas (cd/m²) or Foot Lamberts (fL) within the application.

The NEC Display Wall Calibrator system supports 3 different methods of Intensity adjustment:

• Maximum Possible Matching - Calibrates all of the displays to the maximum possible luminance that can

achieve a match in both Intensity and White Point. Use this option if it is desired that all of the displays

match in both color and brightness. All of the displays will only be as bright as the dimmest display.

• Maximum Possible Per Display - Calibrates all of the displays to the maximum possible luminance that

each individual display can achieve, while matching up the white points on each display. Use this option if it

is desired that all of the displays match in color, but is not important if they match each other in luminance.

• Specic Level - Calibrates all of the displays to a specied target value of luminance, while matching

the white points on all displays. If a display can not achieve the specied value, it will be calibrated to the

closest possible Intensity, and a warning icon will be displayed after the calibration process is completed.

Use this option if the particular application requires a specic luminance, but keep in mind that each

display must actually be capable of achieving that value.

The difference between Maximum Possible Matching and Maximum Possible Per Display Intensity adjustment types is
