Tonight I set up a test installation to see how a new Bewinner 1 LED video wall controller would work with four old TVs. It seemed to work nice after some re-configuration. I used four HDMI to RCA convertors to connect to the TVS. I was pleased with how this set-up worked. I will re-think how I may use this new tool in a future presentation.
Take away from this practice:
Looks like the videos will need formatted/centered better
The conversion from HDMI to RCA worked well, but this may have been key to centering. Will check how these look on single screen.
