That was my first idea too, so I spent several evenings trying to find 
out the correct
modeline to drive the thing via DVI. The exact specs of the modelines it 
accepts are
even given in the manual, but they simply do not work via DVI (they do 
via VGA).

So I asked a Samsung employee (they are consulting customers in big 
electronic retailers),
and he told me what I did not want to hear, that the panel will only 
display something, if there
is HDCP spoken on the DVI port. We both agreed on the fact that it does 
not really make
sense in that direction, but we has not able to help me otherwise.

Seems like I'm stuck here ...

Kind regards,
