SOLVED:

So the mini HDMI cable was very loose. I used some jewelry pliers to crimp the male connector and made a tighter connection, now It works!

Pre-solve Update:

So it seems that the problem is jnfact the mini HDMI port on the camera itsself. If I hold it in VERY firm ajd at a specific angle, I can get it to send signal for 2 seconds before it disconnects again.

This is very sad, as a fix doesn't seem to exist, and I can't afford to send it out for repairs. Belgium bummer.

A friend gave me a Panasonic LUMIX GH4 a while ago. I got it working using the mini HDMI out on the camera and this capture card and through a powered USB hub (also tested through direct to PC). Now after refiguring my setup, I had to disconnect my camera from my setup for a few minutes to move things around. However everything was turned off before disconnecting. I plugged everything back in, and now my source on streamlabs displays my capture card as just a black screen. It registers that it is connected, but there is nothing going through. could it be a setting in the GH4 that got reset, the HDMI port on my GH4 is faulty, could it be the capture card? I'm at a loss and I am very distressed over this. Is there anyone out there, or a community who can help me?
