I have had a problem with getting a picture on my Flyer's Composite monitor since I picked it up about a year ago. I have purchased a Blackmagic SDI - Analog, couldn't get that to work (tested with a RED that I don't have access to right now). Yesterday I went out and got a Decimator MD-HX and still cannot get a picture to show up. I contacted Decimator, and Blackmagic, and both are not sure how to do it. I am testing it with a DSLR and A7s II. ANY help would be greatly appreciated.
