1. A display monitor, comprising:
- an interface which receives a command issued from an external device and sends data to the external device;
a monitor circuit which drives a display monitor to produce an image on a screen of the monitor according to a video signal inputted to the display monitor;
a rewritable memory which temporarily stores adjustment data used by the monitor circuit for a currently displayed image;
means for transferring the adjustment data in the rewritable memory to the monitor circuit;
means for reading out the adjustment data from the rewritable memory and for sending the adjustment data to the external device via the interface;
means for recognizing a command inputted via the interface from the external device, said command identifying an adjustment parameter and specifying an adjustment amount; and
means, responsive to the command, for replacing data in said rewritable memory with data corresponding to said adjustment parameter and adjustment amount.

Abstract
A display monitor which has the monitor circuit 10 for driving the monitor 9 such as a cathode ray tube, the monitor control CPU 14, the EEPROM 11 which stores control data for monitor circuit 10, the RAM 12 which temporarily stores adjustment data of monitor circuit 10 necessary for a currently displayed image and the serial interface 8 which performs a data communication between the computer 1 and the monitor display 2. Based on a command received via the serial interface 8, the monitor control CPU 14 reads data in the EEPROM 11 and the RAM 12. Then, the monitor control CPU 14 sends the data to the computer 1 via the serial interface 8.

7. A method for changing one or more parameters of a display device via an external device, said display device including a non-volatile memory device and an interface circuit connecting said display device with said external device, the method including the steps of:
-
transmitting a first command from said external device to said display device, said first command identifying one or more display parameters stored within said non-volatile memory; receiving said first command at said display device; reading out said parameters identified by said first command from said non-volatile memory; transmitting said read parameters to said external device; receiving said read parameters at said external device; and transmitting a second command to said display device instructing said display device to change one or more parameters stored within said non-volatile memory, said second command including replacement data; receiving said second command at said display device; replacing said one or more parameters identified by said second command with said replacement data included with said second command. - View Dependent Claims (8)
