    RX480 loses display when 2nd HDMI Port is used


      SO i have this really weird issue with my RX480 where with one monitor plugged into either HDMI it runs perfectly but the second another monitor is connected to the other HDMI it stops displaying on either monitor. If i unplug either screen it starts displaying again. I have tried everything i can think of to fix it but have come up with nothing.
