The Auto Luminance feature, available on the LCD2490WUXi, LCD2490WUXi2, LCD2690WUXi, LCD2690WUXi2 and LCD3090WQXi, uses an internal sensor to constantly measure the luminance of the CCFL backlight used to illuminate the LCD panel and generate an image. These measurements are used to regulate the luminance of the backlight so it remains as constant as possible despite changes due to temperature variations and normal ageing of the display. Using the Auto Luminance feature means that the display won’t need to be calibrated as often and that it will become stable in luminance sooner after powering on. Using this feature will increase the calibration time slightly, and may have a very slight impact on the contrast ratio of the display when calibrated. The Auto Luminance will not be used if the Target setting is near to or above the maximum possible Intensity of the display, or with Targets with Maximum Possible Intensity selected.
