Monitor repair company has never heard of displayport!!!

I had a BENQ monitor whose displayport input died.  We shipped it to get fixed to the monitor repair company in Montreal that handles BENQ. The technician calls us to tell us that the analog and DVI work, but he cannot test displayport as he has nothing to test it with, besides it was just turned off in the menu so it should work!!!

Turned off in the menu? No, the menu offers autodetect or you can choose which port is going to be the main focus, but you cannot TURN OFF a port.  Does he think that a company that specializes in graphics cards would not know when a port is dead? Besides this would not be the first LCD who's displayport  port dies but the analog and DVI port still work fine.  What's the point of having 3 ports if one of them is dead?

I cannot believe that 2 years after displayport LCDs have been on the market that a company that repairs monitors does not even have a displayport cable or a displayport card to be able to test them!!!!

Personally I would ask to speak to the big boss and suggest that if they consider themselves a serious company they should not call the client to ask for cables and cards, but should get them themselves. Also worth noting BENQ does not ship with displayport cables, so I would not ship it with one!!!! And I have a 2nd monitor exactly the same that works.

EDIT 10-03-12: On my 2nd BENQ monitor, that was displaying graphics in displayport, we did notice in the menu "DP autodetect"  and it was at OFF. Yes...  the port works regardless and you can use all 3 sources at once and cycle between them even if DP autodetect is at off!!! I still cannot believe that tech was that incompetent.
