Abstract

An apparatus and method for displaying the status of a current display power management signaling (DPMS) mode in a display device uses an on-screen display (OSD) circuit. The current DPMS mode is determined based on an input status of video sync signals and the connection of a signal cable. The current DPMS mode status data is stored in an internal memory of a microcomputer. The OSD circuit is driven using an OSD drive signal output from the microcomputer, so that a message indicative of the stored status data can be momentarily displayed on the display device. In a DPMS mode, any front panel key acts as a program interrupt for DPMS mode operation, which, upon activation, initiates a sequence whereby the DPMS mode is set to normal, horizontal and vertical sync signals are generated, the stored DPMS mode status data is read, and an OSD drive signal is generated. After a time sufficient for user recognition of the current DPMS mode, the OSD drive signal is discontinued and the DPMS mode is reset.
