Abstract
A method and apparatus provide a user interface for control of a display device. A video signal is provided to a display device and a graphic image is displayed by the display device. The video signal may be provided to the display device by a host computer system coupled to the display device. Input to the host computer system is received by a user manipulating the graphic image via an input device. The host computer system responds to the input by communicating a command to the display device, the command for adjusting a parameter of the display device. The parameter may be selected from a group consisting of: brightness, contrast, horizontal orientation, horizontal size, vertical orientation, vertical size, tilt, pincushion, and color tint for the display. The command may be communicated via a data sequence sent to the display device by the host computer system. The data sequence may be encoded onto the video signal sent to the display device by the host computer system. The command may be communicated via a digital protocol which provides for bi-directional communication. The input device may be one or more of: a cursor control device coupled to the computer system; and a keyboard coupled to the computer system. The graphic image may include one or more of: a task window which provides a graphic menu; a graphic representation of the parameter, the graphic representation changing in response to said input by the user; a sliding scale; and a numeric value.
