I have ATI Radeon HD 5770 and I'm trying to connect 3 monitors : Two of them are connected using mini DisplayPort to HDMI and one DVI-D to DVI-D. I can only get two of them work at the same time. What do I need to make it work?


The DVI-D to DVI-D connected monitor supports the resolution of 2560x1440.


I really need some help with this as the new monitor has just arrived and I cannot use it.

Mac Pro, Mac OS X (10.6.8)
