Can I get the same 1920x1200 (or better) resolution with this card from my 2x 23" HD ACD on my macpro1,1?

From previous questions I see this card will work on MacPro 1,1. I need to run 2 x Apple Cinema 23" HD displays and want them the same resolution? Currently using the ATI Radeon X1900 XT that has 2x dual DVI ports. If an adaptor is needed, do I need the dual or Mini Display port to Dvi adapter?

    yes you can, I run 2x 30" ACD's at 2560x1600 BUT i had to buy a display port to Dual Link Dvi adapter for one of them to plug into the display port socket. the other goes into the normal DVI socket.

    you'll get the native resolution of your 23" monitors, (or lower) but to force your display to run at higher than the actual pixels on screen you'd need graphics drivers that are willing to allow non-standard pixels - and these arent available with theATi Drivers that run natively. also the picture would look a bit rubbish!.
