Is there any way to differentiate between active and passive displayport adapters using the ADL.
I'm specifically looking for a way to find out whether a display is connected using a passive or active adapter.
you can determine the connection type by checking the ADLDisplayInfo structure. The structure contains the iDisplayConnector element. This element indicates if a DP, DVI-I, DVI-D etc connection is used. Unfortunately you cannot determine the type of dongle. A display connected via active dongle looks like a DP connection and this is waht the iDisplayConnector would return in this case. For a passive dongle iDisplayConnector would be DVI-D.
