we're trying Qlabs for a show I'm running to send out lighting(hog 4)/audio/videos (media server) cues. We want to send out up to 3 different videos at the same time from a macbook (1 LED wall, 2 tvs). What do we need to make this happen, software/ or hardware. So pretty much a box that takes in a hdmi and it takes the 3 different videos and splits them and sends each one to each source. Also if this isn't possible, let me know.
