Abstract
Abstract A control interface system governing the operation of an autosync multi-format display monitor. Incoming video signals are measured to discern the attendant timing format. Calibration of the monitor responsive to the video signal is made on selected display parameters defining the structural characteristics of the displayed image. The calibration system is both simplified and highly versatile, permitting quick and accurate calibration of disparate incoming signals.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
129 words
In combination in a display monitor control system for controlling an autosync monitor of the type capable of receiving video signal transmissions having differing timing formats, wherein said control system comprises: a. memory location access means for accessing and retrieving timing format and display parameters associated with said timing format from addressable memory locations; b. display parameter indicator means for indicating entry into a calibration mode for the calibration of at least one of said display parameters; c. display parameter selector means for selecting one of plural display parameters for calibration; d. display parameter incremental adjustment means for adjusting a display parameter selected for calibration; and e. display parameter storage means for storing in memory calibrated display parameters associated with said timing format values in said accessed memory location.
Claim 2
Dependent Claim
27 words
The monitor control system of claim 1, further comprising recall means for replacing a display parameter undergoing calibration with a stored value corresponding to that display parameter.
