Thanks for the insight! I was hoping to avoid an I/O card. Was wondering if there was a software workaround to be able to use the displayport cable to monitor the signal. I use an HDMI splitter and all my footage is recorded directly to apple prores 4:2:2 via the Ninja unit. Just wanted to have another of the hdmi feeds go to the MBP to enable me to use the vectorscope capabilities instead of having to get the footage from the ninja an interrupt the filming just to review the footage with the vectorscopes, etc..
It sounds like an I/O card will be the only option for monitoring the footage live. Thanks.
Best Regards,
