U2717D, Nvidia FX 5800, HDMI signal not detected

I received Dell U2717D as a replacement for a similar monitor.  I had hard time getting it to work with my NVIDIA FX 5800 video card.  I spoke with Dell support many times and they couldn't figure out why the signal is not getting to the monitor.  I tried these different configuration of cables: 

DVI at (Video Card)  to HDMI at (monitor) ====  I got the the error HDMI signal not detected

DVI at (Video Card)) to DP at (monitor) ==== I got the the error DP signal not detected

DVI at (Video Card) to miniDP at (monitor)====  I got the the error miniDP signal not detected

As shown none of these cables made the Dell U2717D work with my NVIDIA FX 5800 card.  Finally, I figured I would try DP to DP cable and use the DP port on the video card (which I never used before).  The monitor worked beautifully with this configuration.  I wish Dell customer support had more information about this compatibility issue.  Nonetheless, it is never too late to add this information to your database.
