摘要： A monitor including an integrated circuit with an operating voltage and a control unit for controlling the integrated circuit is provided. The control unit includes a driving unit, a counter, and a resetting unit. The control unit is used for sending out a command to drive the integrated circuit and receiving an acknowledge signal responded by the integrated circuit. The counter is coupled to the driving unit, and the counter value of the counter has an initial vale. The resetting unit is coupled to the counter for resetting the control unit. When the operating voltage is lower than a threshold voltage causing the integrated circuit to be shut down, the driving unit will repeatedly send out the command to drive the integrated circuit. If the driving unit drives the integrated circuit but the integrated circuit does not respond the acknowledge signal, the counter value will be increased by one. When the counter value is larger than the first value, the resetting unit will reset the control unit to restore a normal operation of the integrated circuit.

The display device has a screen, a display micro-processor and a storage unit. An original OSD parameter is stored in the storage unit. The method includes the following steps. Firstly, an OSD compiler is provided in a host for being displayed on the screen. Next, after a user adjusts the display characteristics of the OSD, the OSD compiler generates a modified OSD parameter. Then, the modified OSD parameter is inputted to the display micro-processor. Next, the modified OSD parameter is stored to the storage unit by the display micro-processor. Lastly, when the screen re-displays the OSD, the OSD is displayed on the screen according to the modified OSD parameter.

摘要： A display device has a display screen, a display circuit, an image correction circuit, a timing pulse generator electrically connected to the image correction circuit, and a switch circuit. The switch circuit has a switch electrically positioned between the timing pulse generator and the image correction circuit, and a key electrically connected to the switch for controlling the state of the switch. The switch controls the transmission of a sampling timing pulse from the timing pulse generator to the image correction circuit. When the key is pressed, the switch is activated to permit the sampling timing pulse from the timing pulse generator to transmit to the image correction circuit. The image correction circuit will then perform an automatic image correction to an image frame displayed on the display screen depending on screen frame signals transmitted from a host computer.
