Hello
I have one project which require to connect 4 Full HD Projectors with Mac Pro to use as multi screen projection screen. what are the good graphics cards available for connecting 4 projectors with Mac Pro ?
Regards
Yogin
Mac Pro, OS X Yosemite (10.10.4)
What specific Mac Pro and OSX version?
What is presetly installed card?
Most cards for the 2006-2012 can handle two monitors, some three. You can install more than one graphics card
I have Mac Pro 2013 with Yosemie 10.10.4.
I have Dual AMD Fire Pro D300 graphics card.
Just connect the projectors with the suitable adopters.
Mac Pro (Late 2013): Using multiple displays - Apple Support
That Mac can support two "legacy" monitors (one with DVI or HDMI) input without problems. For more than two legacy monitors you need active adopters.
f the resolution is greater than1920x1200 you need a dual-link adopter with requires USB power.
A mini displayport>VGA adopter is always an active type.
mini displayport>DVI and mini displayport>HDMI adopter can be either with active ones costing more
thanks for your reply.
can you please suggest what active adapters are useful for connecting 4 different hdmi projectors with mac pro ?
I have not used this specific adopter:

But I have used an active mini displayport>DVI adopter made bu the same company, StarTech
Can i use 4 mini display port to hdmi adapers for my mac for expanding display to 4 projectors ? if yes then what is the system architecture ?
Yes. If these are the only four "monitors" connected at least two of the adopters have to be active,
You can only have a max of two non-active. legacy "monitor" connections.
Macs have supported a multi-display feature called Extended desktop since system 4.5 with MultiFinder (circa 1987) each display is appended to an edge you specify and makes up one big Extended desktop. This graphic may help explain what it does:
windows can be placed on one display, dragged to another display, or split across display boundaries with impunity. It is supported by every well behaved Application, except those that deliberately choose to defeat it (iMovie was on that list, not sure if it still is).
is there any graphics card which enable me to connect four projectors with mac pro ?
Is not your question already answered in the above replies?
The Hardware you have will support up to six displays, provided no more than two are "legacy" displays. "Legacy" display is anything other than DisplayPort or Mini DisplayPort. To support more than the first two "legacy" displays, you need to use ACTIVE adapters, available for under US$40.
The built-in HDMI port counts as a "legacy" display.
The second could be supported with "any old HDMI adapter" from a Mini DisplayPort (plugs into ThunderBolt port, and picks up a subset of ThunderBolt equivalent to Mini DisplayPort).
The third, and fourth, and further would need ACTIVE adapters to HDMI. lllaass suggested one made by StarTech above.
