I'm trying to install a Decklink 4K 12G Extreme in a newish computer with an Asus x570 motherboard, but it doesn't show up in Device Manager or anywhere else. The card is in a PCIe 4 16-lane slot which works fine for a Decklink Duo 2. When I install the 4K 12G card in a much older HP Xeon workstation with an Intel C602 chipset, it works fine. I've seen some posts that suggest that Blackmagic cards don't play well with Asus motherboards, but nothing definitive. I've also seen a post suggesting that removing a pull-up resistor from the Decklink card might solve the problem, but it was applicable to systems with two decklink cards, which isn't my situation. I have an Nvidia 3080 in the other PCIe 16 lane slot, in case that matters. I have power running to the Decklink card, and the fan spins. Any ideas?
