2560x1600 display issue due to copyright issues ?

[Linuxguy123]

"The Dell 3007WFP and Hewlett Packard LP3065 30" LCD monitors require a
graphics card with a dual-link DVI port to drive the ultra high native
resolution of 2560x1600 which these monitors support. With the current
family of NVIDIA Geforce 8 & 7 series HDCP capable GPU's, playback of
HDCP content is limited to single-link DVI connection only.  HDCP is
disabled over a dual-link DVI connection."

So it seems as though copyright issues prevent graphics card or laptop
manufacturers from enabling the full bandwidth of an HDMI 1.3 port and
thus regular users like me from using a U3011 monitor for work purposes.

It should be noted that the member who posted that little tidbit of
information has answered that question and only that question.  Seems to
me he is an industry insider.
