Good point about the protocol converters, though I don't recall seeing any way to distinguish between a DP and a DP++ connector in nouveau, nor do I know if nVidia actually made any boards with DP that isn't DP++.

DP++. Good point a= bout the protocol converters, though I don't recall
seeing any way t= o distinguish between a DP and a DP++ connector in

isn't DP++. I gues= s I have some digging to do in that direction. Thank
you.
