Displayport required for Eyefinity?

[somewhatdamaged]

Hi,

I have two 5850's in Crossfire, giving me 4 DVI ports in total. I have purchased 3 x Samsung SM2443BW 24" monitors, but read that one screen MUST be connected via Displayport?

Could someone let me know if this is the case?

many thanks

I see Apple also sell a Mini DisplayPort to Dual-Link DVI Adapter, would this also do the job?
