Where to find owners of multi-monitor systems?

Question

Multimonitor

About a year ago I wrote a program for brightness control and forgot about it. In recent months, people began to write, one, two, three, in general, I realized that someone needed it and rewrote it from scratch, eliminating all errors and adding a few settings. For peace of mind, I would like to test brightness control and synchronization on large multi-monitor systems, and they are expensive and quite rare, so I'm looking for owners.

I tried to find articles on Habré about multi-monitor systems (who assembled and configured how), but there the authors have not visited Habr for several years and it makes no sense to write to them. Among my colleagues, there were no owners of such systems either.

In general, I throw a cry for help, I'm looking for contacts (you can in a personal on habré or on admin doggy brightmaster.ru) users of multi-monitor systems for 4-6-10 monitors. I would like a real feedback. Of course, the program itself is extremely simple and there is nothing besides adjusting the brightness, but how does it work with a large number of monitors, what are the delays in synchronization, what are the delays in adjusting, maybe everything slows down terribly...
