Patent ID: 7990404

Claim:
A method for automatically detecting and switching video signals on a monitor having: an input connector receiving an input video having a video resolution; multiple other input connectors; and multiple setting buttons; said method comprising steps of: storing multiple menu groups in the monitor, and each menu group comprising multiple similarly public resolutions; executing a resolution identifying mode after the monitor is turned on, wherein the step of executing the resolution identifying mode comprises acts of: determining whether the video resolution of the video signal matches one of the resolutions in one of the menu groups; and creating a launch menu to show all the resolutions in the menu group having the resolution matched to the video resolution of the video signal when the video resolution of the video signal matches one of the resolutions in one of the menu groups; and executing a source switching mode comprising acts of: determining whether any setting button is pressed; determining whether all input connectors receive the video signal when one of the setting buttons is pressed; automatically detecting all input connectors when one of the input connectors receives the video signal; creating a launch menu to show all input connectors receiving the video signal on the monitor; determining whether the input connector is in a saving power mode when the input connector does not receive the video signal; automatically detecting all input connectors and creating a launch menu to show all input connectors receiving the video signal on the monitor when the input connector is not in a saving power mode; and automatically detecting all input connectors and switching to another input connector when the input connector is in a saving power mode.
