Hi,
did someone use a 4k input card on Catalyst
i tested a Blackmagic Thunderbolt ultrastudio 4K but Catalyst converted a 4K resolution to a HD resolution.
it is the same with the Decklink 4K Extreme 12G Pci card.

Beware of the Blackmagic 4K, it is not true 4k and will only input at 25/30fps and not full 50/60fps.
Ended up sticking with 1080@50p for cleanness of image.

I used an AJA io4k
Did you check the Blackmagic settings in the control panel... maybe the downconversion was active
I would always take AJA over Blackmagic for input support and latency.

just didnt work when i tried to make it work-
I have the AJA io4K working on my desk right now. mlorenz have you had any luck accessing multiple inputs on the AJA as in SDI 1 & 2? I am hoping i don't need one Aja per input and can use the 2 SDI's and the HDMI as discrete inputs into catalyst.
I used the aja io4k with the 4k input-option and 4 SDI inputs.
So 4 Full-HD quarters, in the catalyst input in then cropped thoses quarters
With the SDI1 and 2 you can only use once at a time when setting the card to Full HD
Is the AJA IO4k a better option than the phoenix cards? how is the latency on the inputs?
Hey Paul,
I can't say that the AJAs are the better Option as I never compared them side by side, but just my feeling says that the AJA 4K got less latency (and you can input 50/60 HZ)...
As a long term Phoenix User I switched to AJA 4K last year, when I upgraded my Catalysts to the recent Macs and definitely no regrets!

with aja io4k could you use it for 4 differents inputs 1080i50hz ?
