After using my 1080 for two weeks (Gigabyte G1 Gaming), yesterday after a bootup I noticed that the card only sends out signal on one of the display ports (it has 3 DP, 1 HDMI). No matter how many displays are plugged in, signal is only sent to one port, o matter how the displays are plugged in after the startup. If there is only one display plugged in at startup, that will be the only active port. After reinstalling the Nvidia driver (Win10) all ports are detected and work again, but the issue reappears on the next restart. More specifically one is active and my two other monitors will have black screen output (one has briefly a white screen before the desktop loads). Is this a driver/mobo issue (I have a GA-Z87MX-D3H) or could this be a HW fault? Could someone have a tip on how to solve this? Thanks!
