I want to use the display port in addition to the two DCI ports.
When I plug in a projector HDMI port through a display port-to-HDMI adaptor Windows 10 assigns a window but the window is not activated so I cannot assign a resolution for the port. When I select Advanced display settings it tells me that the Epson PJ is connected but the Display is not active.
I am stuck. Where do I go next?
