vmix external for decklink sdi capture card

Hi!
I have an issue with sending external playback output from vmix to decklink sdi capture card output
(old card without cooler on the board - see the picture in attach file
decklink sdi pci.jpg

).
The problem is that I have only camera picture from the decklink sdi capture card input directly sending for the output by default without any operation in software. When I tryed to start external in vmix it has an error message about bad video format. But when I delete sdi input as source and send to external sdi just other picture or titles after pressing external button the picture from camera on sdi input is breaking by black screen and then all is going good.
In the card driver setup I didn't see any setting about disabling of swithcing of send input to output directly.
How to fix this?
Thanks

I'm not sure the original Decklink SDI has separate input and output channels.

I'm sure that this card has it both and the REF as well

It seems to me that you need to replace the motherboard. Probably the PCI card gives you bad voltages and maybe that's why I do not want to act. I had a TV tuner similarly

The SDI 4K is a full duplex card, but I doubt the older HD version is.

The older HD card is not a Full duplex card.. Which means you can only use it to do input OR output at once..

The new 4K cards can do both at the same time. As does the Decklink Duo and Quad card..
