Video Wall Demo

Each of my projects is different, but here’s a brief post that might help answer questions about how I span video across many different displays.
In this eight monitor setup, I’m dividing the top four monitors and the bottom four monitors between two 2x2 video wall controllers. Each of the video wall controllers splits the signal into four HDMI outputs which I then run into four HDMI-to-analog converter boxes and then into the back each monitor with analog cables. I did the same with the bottom four monitors.
The video wall controllers are connected to my Mac with two HDMI cables through a single DisplayLink USB-C Dual HDMI adapter. I use this adapter because my M1 Macbook normally only allows two external displays and I want to use my large LCD work display in addition to these video controllers. DisplayLink devices require a driver download and the device needs to be DisplayLink enabled. Often they are hubs with lots of different ports but this on from OWC just has two HDMI ports. When connected, each of the two video wall controllers
appears as a single monitor on my Mac.
I use VDMX to span between both the top and bottom video wall controllers and the video wall controllers distribute that signal across all eight monitors. Typically, I then use VDMX to adjust the video to correct for video stretching, bezel width, etc. for each of the eight monitors. In this video, I didn’t do that. BTW, the full-screen spanning feature does work in VDMX’s free trial version.

In my video, I alternate between the term “monitor” and “display”, but I hope it’s clear enough that I mean the same thing. Also, there are other ways to do this and other tips to explain, so I plan on doing a deeper dive into the different methods someday.
