Abstract
Systems, apparatuses, and methods are described herein for phase locked multi-display synchronization. In a slave display device, a first tearing effect signal is received that indicates rendering of a first image frame portion of a first image frame by a master display device has at least been initiated. In response to receiving the first tearing effect signal, a second image frame portion of a first image frame is retrieved from a frame buffer and is rendered to a display screen of a slave display device. In response to rendering the retrieved second image frame portion, a second tearing effect signal is generated for receipt by a host device to trigger the host device to transmit a second image frame portion of a second image frame to the slave display device.
