That's noteworthy. It seems this model only includes one HDMI port and three display outputs.
everything should function properly then. are you connecting with a PCIE power cable that has a pig tail? one cable or two? using a pigtailed cable might not provide enough power to your card, so two cables could be better. depending on the model, the PSU can only supply about 250 watts through one PCIE cable, while each 8-pin connector delivers around 150 watts. issues may appear in various ways.
The card features just one 8-pin connector, so it requires only a single cable. Your 2070 used an 8-pin plus 6-pin connector, but you connected it with a pigtail and two separate PCIE power cables without any issues.
Yes, it seems related to the port. The one connected to the main DP (the left of the HMDI) is functioning immediately. After swapping the card for a new one, the port shouldn't be faulty. I've seen online that sometimes cards have compatibility problems. You might want to test another MSI model that fits your motherboard.
It seems your setup isn't behaving normally with HDMI/HDCP connections. I experience similar oddities with my monitors—two 1440p LG displays via DisplayPort and an Aorus 48" OLED on HDMI. The devices appear to react only when the 48" OLED is active, but they work fine once it's off. This pattern has appeared with your RTX 3070 and now the RX 7900XT, suggesting a persistent issue that may require a solution unless resolved.
