how to push video out a dell laptop "display port"?

[Robert P. J. Day]

  i have in front of me a dell latitude E6500 laptop (WUXGA display)
running F10, with one of dell's funky new "display ports" on the back,
as opposed to a standard DVI or HDMI port.  all i want to do is push
video out that port to a WUXGA samsung flat-panel display, which i've
been able to do for months from an older dell inspiron that had a DVI
port.

  i'd never seen one of these "display ports" before, and had the
powers-that-be order the apparently essential adapter cables (one
DP-DVI, one DP-HDMI).  but i have been utterly unable to get video out
that port.  in fact, if i boot the laptop with the port connected, i
get absolutely no video in *either* place.

  has anyone messed with one of these?  can you share the secret?
thanks.
