I'm using the following setup:
Intel Core i5-6600
Kingston 8GB DDR4-2133
GIGABYTE GA-H110M-DS2 H110
MSI R9 270X
2x Dell U2515H Monitor
Windows 10 Home 10.0.15063 Build 15063 64bit
AMD Radeon Software 17.7.2 Crimson Relive
Graphics Driver Packaging Version 17.30.1041-170720a-316467C-CrimsonReLive
The problem I'm having is that I can't get a signal from the displayport. HDMI (2560x1440) and DVI are working fine. When connecting the displayport, the monitor recognizes something but goes to power saving mode instantly - as it does e.g. when the cable is connected and the computer is shut down. It doesn't matter which monitor I try. I tried different displayport cables. I also tried a displayport -> hdmi cabel. The problem is the display port of the graphics card.
I guess it has something to do with drivers or has OS-related reasons. What can I do? I would be grateful for any help.
Thanks and regards
