摘要： A control method and device for a monitor, which is used for controlling the brightness, the vertical size, the horizontal size and the contrast of a monitor screen; by means of the minor and slow variation of the size and contrast of the monitor screen, a user's pupils can move naturally so as to reduce the fatigue of a user's: eyes. When the time set is up, a voice will be sent out to remind a user to have a break. The aforesaid device comprises an input setting unit, a microprocessor, a vertical size control circuit assembly, a horizontal size control circuit assembly, a contrast-control circuit assembly, a brightness-control circuit assembly, a voice module, a sensor, a power-supply control module, and a manual/automatic switch. The microprocessor will send out, in time sequence, an increasing or decreasing control value, in accordance with the ratio and period preset, to the various output-control modules to change the output-control modules to change the output voltage thereof so as to control the brightness, the contrast, the vertical size and the horizontal size of the monitor. By means of detest of the sensor, it can be determined whether the input power supply should be turned off or turned on, and whether an output signal should be sent out to control the output-control module and the voice module so as to save power and to control the image of the monitor.
