Connecting more than 2 HDMI displays to Mac Pro
I have a mac pro late 2013 model running yosemite 10.10.5. I have tried to connect 3 HDMI displays to it but it just doesn't seem to work.
1 screen is connected via HDMI port and the other 2 via HDMI to Mini-display adapter. I checked all the adapters and they work fine on the same mac pro because when i try to connect any 2 it works absolutely ok. I also borrowed another friends adapter and tried all three via the Minidisplay/thunderbolt ports but that didn't work.
I came across this - Use multiple displays with your Mac Pro (Late 2013) - Apple Support but it doesn't mention what to do for more than 2 HDMI displays. Also the same setup with my early 2013 mac book pro 15inch works perfectly. so i am guessing all my adapters and cables work ok.
Can someone please tell me what to do. Basically i need it working urgently in my studio for dubbing sessions with video sync.
Thanks
Mac Pro, OS X Yosemite (10.10.5)
