[quote]Dave Baumann seems adamant that DP is and enabler of this, so maybe the lack of DP on older cards is a problem....?
What he's adamant over is 3+ ports working...and truth be told, he is correct that if you want more then 2 ports working this DP port method works.
I see no reason why they should exclude 2 screen EyeFinity from -- to borrow a term from him -- "legacy" cards. To borrow another term from him, it could be done as "value added" for free. There is no extra hardware needed to pull it off. Just need for Catalyst drivers to see the 2 available screens in use and use them. :wink:
I don't see why Dual screen shouldn't work on legacy cards.
(are there any pre 5xxx ATI cards that support 3 monitors at once? ) or even triple screens on legacy cards.
if SofTH can get triplehead working why can't ATI (or Nvidia) do that for the matter.
SofTH do it through the PCIe bus I wonder of ATI/NVidia can do it internally through the card.
I KNOW it's possible but they won't do it for cost vs profit reason.
