I am trying to build a new workstation PC at the moment including a Blackmagic Design Capture Card.
I am thinking of the Decklink Quad (https://www.blackmagicdesign.com/de/products/decklink/techspecs/W-DLK-36). Blackmagic says, it uses 8 PCIe Lanes for capturing. My mainboard only supports 4 lanes on the second PCIe Slot and I am using my graphics card in slot 1.
What would happen if I use the capture card with only 4 lanes?
Does it work at all? Am I limited in my resolution?
