Abstract
A processing system synchronizes the display of a frame of video at an array of variable refresh rate (VRR) display modules of a display wall by dynamically adjusting a frequency and phase of the refresh rates of the VRR display modules via network protocols based on a selected master timing signal. The processing system selects a master timing signal and transmits the master timing signal to video processing units (VPUs) that render portions of the frame for display at the VRR display modules. Each VPU adjusts the frequency and phase of the VRR display modules for which it renders portions of the frame based on the master timing signal.
