description In one embodiment, video content displayed across a plurality of display devices is synchronized by first obtaining a first set of VSYNC timestamps for a display controller of a first video display device and a second set of VSYNC timestamps for a display controller of a second video display device. An adjustment factor is determined based on a comparison of the first and second VSYNC timestamps, and an adjusted VSYNC period for the display controller of the second video display device is programmed based on the determined adjustment factor. After a predetermined number of VSYNC cycles, the display controller of the second video display device reverts back to an original VSYNC period.
