I am currently using the ASUS EAH560 video card with the vga, hdmi and dvi outlet ports. I cannot get to 3 screen s running at the same time.
Regarding the Footnote 2 mentioned above:
Footnote 2 confirms this even more:
ATI Eyefinity technology works with games that support non-standard aspect ratios which is >>required for panning across three displays and to enable a third display you require one >>panel with a DisplayPort connector.
I would like to point out that it REQUIRES a Display Port outlet, which is not present in either mine of your card. I have not tried the card with the Display Port, but do think I will do so soon.
