Oh damnit, didnt see that you were talking displayport to vga, my bad(figured you were talking about dvi-displayport, i'm gonna play the it was early this morning excuse). The reason that the passive dvi-DP adapters will not work is the absense of a TMDS chip for the displayport, hence the need for an active one.Nope, the passive DP to DVI adapters don't work because it's a straight signal swap. The DP to VGA adapters are actually active (even without external USB power), using some power from the display port itself to convert the signal to analog VGA. This is why they work.
