How did this passive display adapter do the job that should have needed an active adapter?


Our 7040 minitower has two standard (not ++) DisplayPorts.  Our monitor is dvi-D (dual-link).

Dell supplied the tower with a DisplayPort to dvi adapter.  The advice received was that this adapter wouldn't work because it was passive.

However, hooked it up and the dvi-D (dual-link) monitor displayed perfectly.

Would anyone know why this adapter succeeded (when apparently it shouldn't have)?
