A few years ago I actually thought about something like this. I was about to go with three 46” monitors on the custom 8-foot sitting/standing desk I built, but ultimately decided to go with three 32” monitors. I’m pretty happy with the setup as it’s a full 6-feet of high definition screen across my desk and it allows me to do a bunch of things. In the future, closer to retirement, I might do three 80-inch monitors in a fashion similar to what’s pictured here.
