ABSTRACT:
A display apparatus for displaying adjustment data for a video display on an on-screen display includes video signal processing circuitry, input circuitry for entering user adjustment data, a microcomputer for receiving the user adjustment data and for controlling the video signal processing circuitry based on the user adjustment data, a memory connected to the microcomputer for storing the user adjustment data and factory preset data for the video display, a display screen connected to the video signal processing circuitry, and an on-screen display portion for displaying the user adjustment data and the factory preset data simultaneously on the display screen. Also, a method for displaying a representation of user adjustment data simultaneously with a representation of factory preset adjustment data for a video display device, includes the steps of writing the factory preset adjustment data in a non-volatile memory section, receiving an input video signal for display on a video screen, receiving the representation of user adjustment data for a video display device parameter to be adjusted, writing the user adjustment data in another non-volatile memory section, generating an on-screen display video signal for displaying on a on-screen display portion of the video screen, thereby giving a user a reference adjustment position during the adjustment of the video display device parameter.
