I just got my new iMac 27" set up with DaVinci Resolve 9. I'm going Thunderbolt to the Black Magic Intensity Extreme, then HDMI to a Panasonic BT-L2150.
Unfortunately, I'm not getting any image sent to the Panasonic. It's a dark blue screen... which for a while turned into a yellow screen (after fiddling with some settings) and then back to dark blue when I unplugged and replugged the TB cable.
I've been using this monitor and HDMI cable with another DaVinci setup on a Mac tower with a Decklink with no issues.
Any idea what might be up? I hope it's just some odd setting somewhere that I haven't set correctly.
