yes this is a known issue Dell will not deal with. I have the same issue.
The video card with display port only allow one way traffic. And Nvidia have done nothing to correct it...last i checked.
The reply i got from

OK so the problem is there is no communications to the display. This is caused by the video chipset / notebook not supporting it. Unfortunately there is not really much that can be done in this situation since it is up to Nvidia and Dell to correct their support. We have informed Nvidia directly of problems similar to this on Dell notebooks in the past, but there seems to be some hardware limitations also.
Other than keep checking with Nvidia and Dell for updates, there is really not much that can be done directly.
You can always calibrate the display on another PC as long as you are using DVI and not analog.
Best regards
Will
