Intensity - NEC KT-X46UN User Manual

Intensity

Intensity specifies 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 specified 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.
Specific Level - Calibrates all of the displays to a specified target value of luminance, while matching the
•
white points on all displays. If a display can not achieve the specified 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 specific 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 illustrated below:
