Hello -
I did a search here and see the latest is from 2014 and it doesn't seemed to be resolved. I am trying to get my iMac (M1) from my production room to display to a projector in our social hall. I have signal coming from our Sanctuary via BM Hyperdeck SDI line going into a switcher (3 SDI in, 1 SDI out). That works perfectly.
I hook up my iMac to a OWC dock (TB) ->display port to HDMI cable out, into BM Mini HDMI converter to SDI into the same switcher. The iMac see's the BM box and extends the screen (so I can move my windows and mouse off the main screen.) I can arranges the displays in settings and mirror the iMac. So clearly, the iMac knows there is another "monitor"
But, I can not get the image to go to the projector. I have tried removing the switcher and going directly into the SDi feed to the room - no luck. I tried setting the iMac to the same resolution as the BM converter. nope.
Is it a resolution problem? My mini converter is 3G - do I need 12G converter? I know the SDI feed into the projector is good because it is the same line we use from the Sanctuary.
Any help/suggestions?
Thanks
