See Blackmagic Sync Generator's switch diagram below :Īlso, when using this method, it is needed to configure each HDMI output for each Fx4 in Wall Designer, so it follows this sync-signal. Configure your sync-signal so its frequency matches the one of your displays : for example 720p60 sync-signal for displays. See schema below with a MacMini 2018 + eGPU (more info about in this article : RecommendationsĪn affordable sync-signal generator is the Blackmagic Sync Generator (around US$200). But this process is long and uncertain.Ģ/ Using an external sync-signal (recommended)Įach Fx4 will get the same signal to synchronize all their outputs together. You can update each Fx4's settings, until all Fx4 frequencies are identical (see image below). To override this problem and frame-lock the outputs for all the Fx4, there is 2 solutions : 1/ Via Wall Designer application Indeed, you can observe that the refresh rate of the 3 monitors (each plugged to a different Fx4) are not in sync. Your browser does not support the video tag. See the slow-motion video below, to understand this phenomenom : This is because each Fx4 can work at a slightly different pace : for example, one at 60.110Hz versus the other at 60.120Hz. However, when you connect multiple Fx4 to your computer, you may get a slightly delay between outputs from different Fx4. The Datapath Fx4 is a great device to handle a output from your computer, and split it into 4 x 1080p60 HDMI outputs (there is also a version with SDI or DisplayPort outputs).Īlso, such outputs are frame-locked by the Fx4, so there is no screen tearing between the screens you connect to the Fx4. How to synchronize multiple Datapath Fx4 ?
