We sell a neurovisual training system that uses two Splay monitors. They definitely fill a niche. The original system we developed used two LCD monitors. Which we still offer, but has its own drawbacks.
As noted, regular monitors and projectors both can outperform for their intended use. But our customers love having a system that packs up small and light for travel and storage (we fit computer, tripods, monitors, etc etc in a small duffle bag). During use, users set them up on a tripods and position them at a distance from the control CPU. We use wireless HDMI dongles that are powered from the Splays. Battery powered and wireless. Customers love it.
Most of the time they are in monitor mode, but for some training scenarios, they are used in projector mode. They are pretty good as short throw projectors.
Are they a replacement for normal monitors or projectors? No. But for certain uses, like ours, they beat the other stuff out there.
BTW, as an interesting aside, the system we have was developed in cooperation with an expert in brain injury/therapy/training. That dude's work is worthy of an Ars article in its own right. His work on triggering neuroplasticity is used with patients with brain injury AND by athletes to improve visual processing and executive function. And the elderly to reduce cognitive decline. He was able to
reduce concussions at a division 1 football team by 80% while improving GPA and win more games. 10 years of data.
My understanding is a new coach thought it was BS, cut the training. Concussion rate went back to where it was before. Restarted the training, concussions dropped low again. Turns out players brains don't process their entire field of view, especially when tired. They see stuff, but the brain ignores it. His training improves visual processing and executive function for the entire game. They don't get as many concussions because they avoid getting hit as much or as hard.
Wild stuff and just the tip of the iceberg on this dude. This was just the easiest story to share.
