Hi there

I have a Mac Pro 2.93 Ghz Quad-Core Intel Xeon - (4GB-1066 Mhz -DDR3)

Serial Number:
J59######4MF

I wish to run 2 - 30" Cinema Displays from my machine - which Graphics Card do I need to order to do  the job successfully?

Many thanks
Geoffrey

    yours came with GT120. Doesn't do the job?

     

    Nothing I can suggest until you are running 10.6.8 or Lion and then ATI 5770 with dual link DVI

    Show us the top of what you find in System Profile, include the graphic adapter.

     

    Even a GT120 which was stock should have two DVI.

     

    And the 5770, re read and study that article. It has one DVI and the 2nd display would need a special adapter for the DisplayPort to 30 inch (dual link).

     

    It is when people get into 3 displays it gets more interesting.

    None of the newer cards come with two DVI outlets. The second (and third) are Mini DisplayPort. To run a second DVI for a screen wider than 1920, such as your 30" cinema displays, you need a Mini DisplayPort to Dual-Link DVI adapter, about $100 from Apple, slightly cheaper third-party.

     

    Dual-Link refers to the number of bits in the display data path -- it does not refer to dual displays.

    The second slot on a GT120 is the tiny Mini DisplayPort. you can adapt it to Dual Link DVI with a US$100 Dual-Link DVI adapter.

    Apple product page: only instead of leaving it "in place" for reference, you get 'bad url'

    NVIDIA GeForce GT 120

     

    So went to Nvidia product page.

    GeForce GT 120 OEM

    All you need to get the second display to light up is the adapter. Apple supports multiple displays on same card or additional cards, no big deal.

     

    Apple sold an optional Mac configuration that loaded up a Mac Pro with four of those GT120 cards, for eight display support.

     

    Any card you buy must have Apple firmware, or you get no picture under Mac OS X.

     

    If you are going to buy another card, you may want to consider a 5770 or 5870 if you are doing graphics-intensive work.

    I have a 2010 powermac g5. I have a 30" cinema display. I also have a 42" sony flat screen from 2005-2006 that I have been using as my second monitor. I have the monitor connected via Mini DisplayPort to DVI using a apple adaptor. RecentlyI have been experiencing problems on my flat screen TV. There seems to be a doubling effect along with TV snow on the screen. I tried changing resolutions and nothing happened as well as buying a new adapter. 

     

    I know currently I have a Nividia GeForce GT 120 graphics card. Do I need to update the drivers or ge a better graphocs card. By me running dual screens, ( a 30" display and a large flat screen ) is it pushing the card too hard of sorts?  Please help !!! 

     

    Thank you for any suggestions!
