  iMac input to BlackMagic ATEM TV Studio Not Working

  Posted by John Johnson on September 11, 2012 at 12:19 am

  Hi all!

  I currently have two Panasonic V700s going into a Television Studio, and would like to add the output of an iMac to the mix. I’ve tried two separate mini display to hdmi adapter, multiple hdmi cables- no dice. I’ve unplugged everything but the iMac hdmi to the switcher- still nothing. I’ve restarted the iMac after plugging it in, changed my display settings to 1080i, 720p, 720×576, 480i and p. (50 and 60HZ)

  The thing is, the iMac sees it correctly as a display (named BMD HDMI), and when it’s set to 1080i 60HZ, I get a brief 3 second computer desktop input to the ATEM. Then it goes black again.

  Any thoughts?
  Thanks for any help!
