UPDATE: after sitting for an hour browsing reddit, the monitor hooked up through DisplayPort was suddenly detected and now it's working. Hopefully it stays working. The monitor plugged in to hdmi using a DVI to HDMI converter still isn't working though.

So today I went to Microcenter and purchased a Powercolor RX 480 Red Dragon 4GB and a displayport cable. After installing it into my system and plugging back in my monitors, it will only display on the monitor plugged in through DVI. The other two, plugged in through DisplayPort and HDMI, refuse to be detected in windows, and the bios screen doesn't mirror.

So far this is what I've done:

- Clean Reinstalled the drivers (3 times, and once with DDU).
- Replaced it with my old card, and the monitors worked on that.
- Gone back to microcenter and replaced both the card itself and the displayport cable.
- Tried only one monitor plugged in at a time, still only DVI connects.
- Unplugged, and reseated the card. Unplugged and reconnected each cable while in windows and while rebooting.

At this point I'm just at a loss, finding nothing online and with nothing left to think of to try, which is why I'm asking here. And I would rather not go back to microcenter for a third time so quickly, as it's a 40 minute drive one way.

Any help would be appreciated!

DP Monitor is the Aos G2260VWQ6
DVI monitor is the Dell 2007FPB
and the HDMI monitor is the Dell E176FPF using a DVI to HDMI converter.

However even if it won't transmit over the DVI to HDMI converter, wouldn't the DisplayPort connected monitor still be detected?
 


Yep I've tried that as well, to no avail.
