Here's the google on that. https://www.google.com/search?q=multiplexing+hdmi+quad+screen
I found this device when googling different gadgets. I saw this one feature that I really liked and that was displaying four screens I guess from multiple sources. Does anyone know of any other devices that can do this acting as an android Smart TV or something of that sort? I would like to have different options than just this one. Thanks in advance.
To see what I'm talking about look at 2:07 in this YouTube video
