Using DeckLink Mini 4K with "unsupported" apps

Hi ,
I was advised by a software vendor to use the DeckLink Mini 4K for capturing images from a medical instrument. Originally the intention was to use software that supported this card; however, at the last minute, the client decided to change to another package.

I can see the video from the device using the Media Express app that comes with the card. However, when I use the app that the client wants to use I'm not able to get an image.

I believe the problem is that the signal format is not correct. The software let's me choose the format but then, because I made a configuration change, forces itself to close. When you open it again, the signal format reverts back to the default!

Is there a way to force the Decklink Mini 4K to use a particular signal format outside of the program that is doing the capture?

Any other suggestions on how to force the video format so that I'm not just seeing a black screen in the "unsupported" app?

Thank you
Sunil

Or contact the software manufacturer that they change their settings so it supports the res and framerate you need.

Or convert the video signal with the use of a Decimator MD-HX to a supported format from that software..
