ABSTRACT:
A system for making display adjustments in a monitor connected to a general-purpose computer converts user inputs at the host computer to digital commands and data words, and places the commands a data as serial packets on the VSYNC line to the monitor. A controller in the monitor receives the serial packets and controls adjustment circuitry in the monitor to adjust display characteristics according to the commands a data received. Adjustments include adjustments to brightness, contrast, display position on a monitor screen, display size and aspect ratio, and commands may include commands to switch display modes, and in some cases to signal the monitor to assume alternative power-using modes, such as a standby mode.
