Abstract: A display system synchronizes data stored in a video signal source and a monitor by detecting the state of a status pin coupled between the video signal source and the monitor. When DDC/CI function is on and a user adjusts the display parameter in the monitor by directly operating the buttons installed on the monitor, the monitor alters state of the status pin to an “inconsistent” state. Once the video signal source detects the “inconsistent” state of the status pin, the video signal source then updates the display parameter of the video signal source according to the display parameter of the monitor.

Abstract: Under the condition of a computer system being powered on, a switch on a monitor controls the power or the display parameters of the monitor according to the triggering time of the switch. When the switch is triggered for more than a predetermined period of time, a control unit of the monitor sets the monitor to the standby state or powers off the monitor. When the switch is triggered for less than the predetermined period of time, the control device then controls the monitor to display video signals from the computer system according to different display parameters.
