Hey Chris,
Does your PC have Thunderbolt ports?
If not, you can get a Blackmagic Declink card. There are a few models and these go into the pcie slots. And BM are reasonably priced too. I’m using a Mac and use BM thunderbolt I/O. I was using a Matrox LE and had problems with their drivers while I was using PrPro CC last year. Switched to BM and it’s been going alright:)
