I have a 10.13 build. Now I am upgrading the build by adding a graphics card R9 280x , every thing works fine, except the graphics card DisplayPort. It unable to output any signal, but ones I Connected graphic card HDMI to a Monitor it both works fine. If I disconnect the HDMI, the DisplayPort Lose the signal. My setup only allows one 4K monitor.
