I'm trying to connect two 4k ultrawide monitors to my PC for multi-display extended desktop setup, but I can't get the other monitor to work. My mobo has 1x DVI-D 1x D-Sub and 1x HDMI outputs. Both displays only have DP / HDMI ports and I have no idea what do I need to hook the other one up.
I've tried a 24-pin DVI-D to HDMI cable but that only gets it to work for a second then shows static, and from what I found that's related to the cable not supporting above 1080p resolutions.
What sort of cable would I need to hook it to the PC?
