Abstract
A graphics system that is configured to synchronize a slave display channel to a master display channel may include a master display timing generator configured to provide a frame event indication and a slave display timing generator. The slave display timing generator may be configured to receive the frame event indication and, in response to receiving the frame event indication during its active display period, the slave display timing generator may be configured to wait until its current active display period ends and then jump to its synchronization point. Alternatively, the slave display timing generator may be configured to jump to its synchronization point immediately or after the end of the current horizontal line, and any remaining display information in an interrupted frame may be displayed during the next active display period.
