so the boards only need the correct firmware flashed onto it - with a Windows PC with a DP port
Thanks! Ok so that does explain it. Unfortunately I’ve tried both a windows 10 and windows 7 machine with display port and their flashing program supplied for the JRY-W9CHUD-AA1 doesn't recognise the card, in the supplied screenshots is shows it will detect the card instead it just says UNKNOW. Have tried a PC on windows 10 also windows 7, just power and display port connected. Hmm. Anyway thanks again for the reply.
