Review on 📺 gofanco Prophecy 4K HDMI 2x2 Video Wall Controller & Processor for Flawless Display - Bezel Correction, Cascading, and Fanless Design by Steve French

This seems like a good product for many purposes but there are some caveats. First, the control software is difficult to understand, and the manual is a poor translation from the original language, which loses a lot in translation. I work with technology all day, so it was to be expected to some degree, but it was difficult to use. BUT, if you don't need to do anything special, this might work well for you. What it can do is flip the top two screens to use the smaller top bezel (at least I couldn't find that after reading the manual and playing around with the software for hours) or mask the bezels. Both features are advertised for this controller.
