Will this work on a desktop PCIE X700 ? I seem to have the same problem
doing stuff with the secondary DVI head. I'd like to have some sort of
setup where DVI #1 is 16/10 1680x1050 most of the time, and is cloned to
4/3 DVI #2 wherever xrandr is used to lower the res to something the
harware on head #2 can understand (typically 4/3 1024*768).

I haven't managed to display anything on head #2 since everything was
cabled in DVI.
