I have a quadro fx 580 card with 2 displayports and a single dvi. I use the dvi for my monitor and would like to use the displayport to hookup a vga cable so I can wireless transmit movies to my TV (got this transmitter to do that). The thing is that the graphics cards does not recognize the adapter when it is connected to the card. any ideas what should i do?
I still think it's a passive adapter, I was only asking if this might be possible so I can check if by any chance I am wrong and it's not passive. Maybe the card can't supply enough "juice" to run such circuitry?
