The other night I finished everything I wanted module wise so i was going to start on hardware (i.e taking monitor out of frame etc) After I took the monitor out of the frame and plugged it in to my Pi I noticed the screen was saying ‘no signal.’ I started to panic as the control for the monitor popped out of the socket so I was worried I just pissed a $150 monitor down the drain. I decide to try my PC monitor and lo and behold I get the same thing… I plug in my future MagicMirror Monitor to my PC and guess what… It works like a charm.
This obviously means something else is wrong…I am literally not at all a computer guy. I took my SD card out and plugged into my computer and I see all the files so that means that is not corrupted/dead right? So it must be the R Pi3 itself? The Pi lights up when I put power to it and everyhting…I tried using both the DVI and HDMI port on the R Pi3

Help would be greatly appreciated.
