RE: How did this passive display adapter do the job that should have needed an active adapter?
' Do you know whether the DisplayPorts on a 2016 Optiplex mini tower (i3-6100 igp) are single mode or dual mode ? '
To be more accurate, I should've asked if the DisplayPorts are single-mode or multi-mode.
As I understand it:
DisplayPort (multi-mode) = Works with both passive adapters and active adapters.
DisplayPort (single-mode) = Will only work with an active adapter
Would you happen to know which mode of Displayport is used in this Optiplex?
