I have an install with two TVs on a track. They are very cool but a total service nightmare IMO. We usually know better but the builder kept pushing and we caved like fools.

They have to be configured with archaic machine configuration software. Things like left right/rotation speed were not the same on each of them. Then you have to choose your preset positions. Every time you lose power you lose your position preset settings. So get a huge UPS and be ready to set the presets whenever it fails.

After power loss we found that a button like "home" would send the TV spinning forever destroying the 70' HDMI and power cable. Hardware limiting devices help but are not perfect.

We had to find another company more familiar with the product to tame it.

Once a year i go out to the project for 2 weeks to upgrade/add/repair things. Every year i have to fix something related to it. The plan right now is that when it completely fails we are going to replace it with something manual where the client would move the TV to the position they want. Nothing motorized.
