Abstract: PROBLEM TO BE SOLVED: To always keep a monitor to a fixed standard state by comparing/ analyzing the voltage data measured with a sensor with the standard data and adjusting voltages of voltage supply devices of red, green, blue supplying the voltages to the electron guns of the monitor. SOLUTION: The sensor 50 measures voltages for three beams by the command of a processor 20 to send the measured voltages to the processor 20 together with the data of the color temp. state of the present monitor. The processor 20 compares the beforehand inputted data for the voltages of three beams in a standard white luminance state for the color temp. of the relevant monitor with the collected data, and judges whether or not the collected data exist within the range of the error of the standard data, and when out or the range, judges whether or not the voltage of the sensor data is lower than the voltage of the standard data, and when lower, instructs a controller to increase the voltages of the electron guns, and when higher, instructs to lower the voltages.
