I am trying to connect the HDMI port on my nVidia GeForce GT 640 video card to the DisplayPort input on my HP Compaq L2206tm monitor. This is the reverse of what is expected by cable fabricators who have lots of cables and adapters for the opposite configuration, i.e., DP on the videocard and HDMI input on the monitor. There seems to be a uni-directional vs bi-directional issue involved with DP, but I don't quite understand it. Anyway, the uni-directional choices I am seeing are in the wrong direction. Anybody dealt with this and what is your advice for me?
