Abstract
Autophase adjustment is initiated in a display device that digitally displays analog video signals. The autophase adjustment is initiated based on monitoring of at least one of the horizontal and vertical synchronization signal pulse rates and polarity. When a change is detected in either of the horizontal and vertical synchronization pulses, an autophase adjustment is automatically initiated. Correct phase settings are obtained from a table of settings cross referenced by the horizontal and vertical synchronization pulse rates and polarity.
