Synchronizing multiple display channels

A graphics system comprising:

• a master display timing generator configured to provide a frame event indication;
• a slave display timing generator configured to provide synchronization signals to a display, wherein the slave display timing generator is configured to receive the frame event indication and, in response to receiving the frame event indication, to jump to the slave display timing generator's synchronization point;
• and
• a display output queue configured to provide pixels to the display, wherein the display output queue is configured to output prefetched display information for an interrupted frame during a next active display period in response to the slave display timing generator jumping to its synchronization point before entering its vertical blanking interval.

A method of synchronizing a plurality of display timing generators, the method comprising:

• providing a frame event indication;
• a slave display timing generator detecting the frame event indication, wherein the slave display timing generator is configured to output synchronization signals to a display;
• and
• if said detecting occurs during the slave display timing generator's active display period, the slave display timing generator jumping to the slave display timing generator's synchronization point after the slave display timing generator's current active display period ends.

A method of synchronizing a plurality of display timing generators, the method comprising:

• providing a frame event indication;
• a slave display timing generator detecting the frame event indication;
• in response to said detecting, the slave display timing generator jumping to the slave display timing generator's synchronization point, wherein said jumping comprises interrupting a frame that is currently being displayed by a display coupled to receive synchronization signals from the slave display timing generator;
• and
• in response to said jumping, outputting remaining display information in the interrupted frame to the display during a next active display period.
