You might have seen some pics here and there of a triple monitor setup at the Soaring Academy here in California. Indeed we'll be making a triple monitor kit available some time early 2022. The design is done, just building and shipping parts takes time. The max size for monitors on this type of setup is around 32-34" and most importantly, you'll need to have a graphics card (Nvidia has a couple) that actually supports 3 HDMI or 3 DP (display port) out to the monitors. Most graphics cards come with two outputs - but that won't work if you want to go triple.
