Abstract

A computer system in which the signal parameters of an analog display signal received by a display unit can be determined automatically. A test data having a predetermined format is sent to a display unit. The test data is encoded to enable display unit to measure display signal parameters such as the timing signals (e.g., start position of each horizontal line) accurately. The test data also includes black and white points, which enable the display unit to measure the voltage levels used to represent black and white signals. Display unit can accordingly adjust the manner in which individual points on a display screen are actuated so that the full scale of brightness levels on individual points can be utilized. CRC-based techniques are used to indicate to the display unit the presence of the test data as the same communication path is used to send test data and display data.
