Method for controlling on-screen display operation of display apparatus with auxiliary input/output terminal

A monitor, comprising:

• said monitor for providing a visual display of a video image;
• a key input unit installed on said monitor and comprising a plurality of control inputs for permitting a user to adjust display parameters of said video image displayed on said monitor and generating a key control signal indicating an image adjustment request from the user;
• an auxiliary input/output unit installed on said monitor and connected to a host computer via an universal serial bus, for receiving an auxiliary control signal from said host computer to adjust the display parameters of said video image displayed on said monitor;
• and
• a controller for controlling the visual display of said video image on said monitor, controlling an on-screen display of an operating state of display parameters of said video image displayed on said monitor, and executing display parameter adjustments of said video image displayed on said monitor in response to receipt of one of the key control signal and the auxiliary control signal.

A method for controlling an on-screen display of display parameters of a video image displayed on a monitor, comprising the steps of:

• providing a visual display of a video image on said monitor, said monitor having a key input unit installed on said monitor with a plurality of control inputs, and an auxiliary input/output terminal installed on said monitor and connected to a host computer via an universal serial bus;
• determining whether a key control signal is input through said key input unit installed on said monitor for adjustment of display parameters of said video image displayed on said monitor;
• when no key control signal is input through said key input unit, determining whether an auxiliary control signal is input through said auxiliary input/output terminal;
• when said auxiliary control signal is input through said auxiliary input/output terminal, determining whether the input auxiliary control signal is to be transferred to said monitor for adjustment of the display parameters of said video image displayed on said monitor;
• and
• providing an on-screen display of an operating state of display parameters on said monitor, and executing display parameter adjustments of said desired video image displayed on said monitor in accordance with one of the input key control signal and the input auxiliary control signal.
