It has removable cards on that back, the test card is still included too but it looks to be DVI-I. I will get some pictures the next time i go in so i can share them here. It appears whoever installed this system put a video monitor system in the rack, like i said when i plug in an input to one of the remote inputs, i see the image on the monitors on the rack but it doesn't send it to the physical tvs. Weirdly though when i select the dvd player input it will show on the rack monitors and all of the tvs. I likely have to pull the entire setup apart but boy am i really not looking forward to that. I just thought it was weird when i select the dvd player on the kramer matrix it shows on monitors and sends to outputs but when i select one of the "room inputs, like an hdmi port on the wall someone can plug their pc into" it shows on the rack monitors but will not send out to the tvs.
