This laptop PC needs to be connected to the RS232 service port of the display The USB color sensor should be connected to the laptop PC The internal test pattern generator of the display is used to create the colored fields needed for the calibration Figure 1 External calibration system Calibration with external computer graphics by using the input source as calibration system Another way of setting up the calibration system is by using the input source as calibration system The computer is connected to the display via RS232 and the color sensor is connected via USB In this scenario the colored test fields are generated as computer graphics For this the display needs to be connected through DVI and driven at native resolution at 24 bits per pixel color depth Figure 2 The input source as part of the calibration system There is no difference in calibration results between the two calibration systems Barco DCMS User Manual 11 About DCMS 3 3 2 3 3 3 IMPORTANT When calibration is done with external computer graphics please restore all color settings of the host s graphics controller to their default value and disable any host services that may affect the color of the output picture Display Each pixel of the display has 3 sub pixels These sub pixels each have a color that corresponds with the three wavelengths for which the human eye is the most sensitive These colors are red green and blue RGB

Each of these sub pixels typically has 256 discrete levels Colors are reproduced by combinations of these three primary colors Gamma is the perceptual linearity of light Gamma is expressed by a power function Color temperature or white point is the color of white We say that the display has a warm white point or color temperature if the white of the display is reddish The display has a cold or cool white point or color temperature if the white of the display is bluish The color temperature or white point is expressed as coordinates in a color space for example xy values in CIE1931xyY space or the temperature in degrees Kelvin at which a black body gets this color Contradictory we speak of warm white when the color temperature is low for example 3200K and cold white when the color temperature is high for example 9300K Daylight has a color temperature of 6500K Gray tracking is keeping the color temperature constant for all gray levels between black and white The brightness light intensity of full white is also calibrated as the power applied to the backlights If the brightness target is set lower than the dimming capabilities of the backlight driver then additional dimming can be applied in the video if the display supports this function Sensor The sensor used for calibration is the Barco USB color sensor not sold separately This sensor has a USB interface to the host PC running the DCMS application Accuracy
