Hey all - I have a Canon 5D EOS Mark 3 camera, with Neewer On-Camera Field Monitor and a Mini HDMI to HDMI cord to connect them. However, when I connect them using the cable, all that happens is that on the LED screen of the Canon Mark 3 is it just flashes. Picture never goes to the Neewer field monitor. It did work before. The field monitor fell off of the camera and didn't hit the floor because of the cable The cable had to be replaced, which I got today, and tried it out and it doesn't work. Anyone know how to fix this issue???
