Hi,
I have quite difficult problem with connection two FULLHD monitors with MAC PRO with Yosemite 10.10.3 (ATI Radeon HD 5870 1024MB). I need connect two FULLHD monitors into one big desktop - resolutions 1920x2160 (1920x1080 + 1920x1080), like video wall. Anybody know how to do it? I need it because of touch foil, which operate just on primary LCD monitor.
Thank you for your comments,
Libor
Mac Pro, OS X Yosemite (10.10.3)
The Apple version of the ATI Radeon 5870 has two Mini Displayport connectors and a DVI connector. You could connect a 1920x1080 screen to each of the two Mini Displayport connectors. The Mac and this card will let you use both at the same time.
The two screens can be configured either in 'mirroring mode' where the same image is displayed on both - which is not what you want, or can be configured in the opposite to mirroring which is called 'spanning mode' which means that they are combined in to one larger virtual monitor.
You use the Displays System Preference pane to setup how they are positioned (virtually) e.g. one on top of the other, or side by side.
If you position them as if they are one on top of the other this would give you the equivalent of a 1920 wide by 2160 tall screen. If you position them side by side this would give you the equivalent of a 3840 wide by 1080 tall screen.
Dear John,
thak you very much for your advise! Problem is, that touch technology need to see LCD monitors together. Your solution works - two LCD monitors, one desktop, resolutions 1920x2160, but the pc still recognize Primary screen and Secondary screen. I have to make just one Primary screen.
Try unchecking "Displays have separate Spaces" in "Mission Control" system preferences, then logout and login again.
Dear Malcolm,
thank you for help. But this is not work. When I set LCDs into matrix, I have to set reolutions to 1920x2160, but MAC does not allowed me.
Do you get a setting similar to this in Displays preferences:

Yes, I do. Just second screen is under the primary screen.
Then the feature is working the way the Mac designers intended.
If you have the correct Macintosh-specific version of the touch foil, then your additional questions should be directed to the makers of the touch foil.
From taking a look at their web site, I do not understand how you could use one touch foil to span two displays. Perhaps they can help.
But it performs the way you expect and want when running under Windows (Boot Camp), right? Windows programs and esp. graphic drivers.
Yes, at W is running well. Problem is, that I have company's SW for OSx...
