Hello, I have a Mac Pro 5,1 "Eight Core" 2.4 (Mid-2010/Westmere) that has an ATI Radeon 5770 (1024 MB) with 2x MiniDisplay ports and 1x DVI port.
I need to use 3 displays on this Mac, the main one is a Slate Raven MTi (1920x1080, connected with a MiniDisplay to DVI cable), the second one is a 27" Samsung (1920x1200, connected with a MiniDisplay to DVI cable adapter), the third one another Samsung 24" (1920x1200, connected directly with the DVI cable).
The problem is I can't get the all 3 monitors to work together.
From the specs here :
www.everymac.com/systems/apple/mac_pro/specs/mac-pro-eight-core-2.4-mid-2010-westmere-specs.html
I've read this Mac/video card "is capable of supporting three displays -- digital resolutions up to 2560x1600 and analog resolutions up to 2048x1536" but also "a maximum of two DVI-based displays per graphics card."
Can this be the problem, the fact that all 3 monitors are DVI ?
And if so, how to solve this ? Maybe replacing one of the 2 Samsung with an HDMI one ?
Thank you in advance

i have same problem i could get the order and the 3 display working, with an active display converter to HDMI, in 3 screen, the only problem is tha i removed the the composite to calibrate again, and then when i make the configure composite gives this message "the number of the overlays does not match with the displays…."

Now i am unable to calibrate the screens, when i take out the 3 screen everything works ok!!!

Any help There Please

You only need to add Composites when using 2 Ravens. The MTplatform is searching for a USB connection to the screen, so that is why "the number of the overlays does not match with the displays…." isn't matching..

In the end I've finally been able to make all the MTi + 2 displays work at the same time.
I used 2 of these (pretty inexpensive) active adapters :
