\"\"Actually, this might be part 3 or 4 of our updates that have captured the attention (and traffic!) of inquiring\u00a0 Mac Pro users around the world. It all got started back in March of 2009 when OWC Larry himself told the faithful which NVIDIA and Radeon video cards worked on legacy machines<\/a>.<\/p>\n

Then, the big bombshell was when we posted this past August which Radeon video cards work with 2006-2009 Mac Pros<\/a>.<\/p>\n

Rather than bury another important update in that recent post and perhaps make this information difficult to find, we thought it best start a new post thread. (But for historical info and some GREAT reader comments, I highly encourage you to visit those above links.)<\/p>\n

While most of us were enjoying an extended weekend of R&R, that uber-tech Rob-ART of Barefeats.com was laboring for the Mac community on getting more insight as to what Radeon cards and displays work with what Mac Pro.<\/p>\n

What he learned was he could get\u00a0 23″, 24″ and 30″ Apple Cinema Displays to work simultaneously on 2006-2010 Mac Pros with both <\/em>the 5870 and 5770 video adapter cards.<\/strong><\/p>\n

How he achieves this feat is as follows:<\/p>\n

1. 23″ Cinema or<\/strong> 30″ Cinema on the DVI port
\n2. 23″ Cinema with Mini DisplayPort to dual-link DVI adapter* on first Mini DisplayPort port
\n3. 24″ LED Cinema with direct Mini DisplayPort connection to second Mini DisplayPort port<\/p>\n

* regular Mini DisplayPort to DVI adapter works if two 23″ Cinema Displays are attached.<\/p>\n

For the full breakdown of his trials and results, visit his site index<\/a> where he’s busy adding the details as addendum to existing articles.<\/p>\n

***UPDATE 9\/9\/10***<\/p>\n

Seems like your interest and OWC’sRob-ART’s coverage of the subject has gotten Apple to note which interfaces one should use when using multiple displays simultaneously:<\/p>\n
