This is a follow up to a previous post I made here.
I RMA'd the Intensity Pro 4K and it was replaced with a new unit. Yet I'm still experiencing the same issue I did with the previous unit; unable to use live video sources above 720x480i resolution. I've tried changing the video standard with lower refresh rates and "other" to no effect. The card was tested with Desktop Video 10.9.7 (latest version at the time of writing).
However, the card works with Resolume Arena 5 at 1080i 59.94Hz so I don't think this unit is defective. At this point I just wouldn't use any more Blackmagic products with my set-up.
