Using both the display ports on the new mac book pro

Hi, are there some one in Appel that can tell me if its possible to use both the display ports on the new mac book pro to show keynote on? or if its possible to make that possible? i would really like to be able to create a keynote with 5120 x 1600 pixels and get that output on two display ports, so that i can use my hardware to make a keynote with really nice reselution. its for use on a screen size of 18x4 meter.

Connect one display to the Mini-Displayport and the other to a USB port using an adapter like this:
http://eshop.macsales.com/item/NewerTech/VIDU2DVIA/
Or buy a Matrox DualHead2Go DP Edition external video box and connect both displays to that, which in turn connects to the Mini-Displayport on the computer.
There are limitations either way. A USB-connected display will be less responsive than one connected to the MDP, because USB 2 is slow. To use two displays with the Matrox box, I believe the displays must be identical. Read and understand all the caveats about each alternative before making a decision about which way to go.

  • I have 12 core with Quatro 4000 and 5770, I want to use dual monitor setup, monitors are NEC with Spectraview-II.  How do I connect?  4000 only has 1 Display Port and 1 DVI.  5770 has 2 of each, if I use both 5770 Display Ports, does the 4000 contribute?

    I just bought a 12 core with Quatro 4000 and 5770, I want to use dual monitor setup, monitors are NEC with Spectraview-II.  How do I connect?  4000 only has 1 Display Port and 1 DVI.  5770 has 2 of each, if I use both 5770 Display Ports, does the 4000 contribute any work at all?  I read where on a PC they would work together, but on a MAC they do not.
    I read that Display Port has higher band width than DVI, NEC monitors for best performance they recommend using DIsplay Port.
    When I was setting this up I looked at a Nvidia Quadro 4000, unfortunately it was for PC, it had 2 Display Ports, in the Mac version they reduce it to one.  I did not think there could be a difference.
    Mainly want to use it for CS6 and LR4.
    How to proceed??? 
    I do not want to use the Quadro 4000 for both, that would not optimize both monitors, one DP and 1 DVI.  Using just the 5770 would work but I do not think the 4000 would be doing anything, and the 5770 has been replaced by the 5870.more bandwidth.
    Any ideas, I am a Mac newbie, have not ever tried a Mac Pro, just bought off ebay and now I have these problems.
    As a last resort I could sell both and get a 5870.  That would work, I'm sure of that, it's just that I wanted the better graphics card.
    Thanks,
    Bill

    The Hatter,
    I am a novice at Mac so I read all I can.  From what I understand the NEC monitors I bought require Display Port for their maximum performance.  The GTX 680 only has DVI outputs.  Difference from what I understand is larger bandwidth with the DP.
    You said I have the 4000 for CUDA.  I am not all that familiar with CUDA and when I do read about it I do not understand it. 
    A concern I have is, that if I connect the 2 high end NEC monitors via the 5770, using it's 2 Display Ports I would have nothing connected to the 4000.  Is the 4000 doing anything with nothing connected?  I read where in a PC system the 2 cards would interact but in a Mac system they do not.
    Bottom line, as I see it, the 4000 will not be useful at all to me, since I want a dual monitor set-up.
    So far the 5870 seems the best choice, higher band width than the 5770, and it has 2 Display Ports to optimize the NEC monitors.
    I'm not sure how fine I am splitting hairs, nor do I know how important those hairs are.  I am just trying to set up a really fast reliable system that will mainly be used for CS6 and LR4.  Those NEC monitors are supposed to be top notch.

  • TS3694 Just took my 1st gen iPod out of it's original box, never used before.  Plugged it into my new Mac book Pro and it recognizes that the iPod is in recovery mode but when I click to restore, error 1611 comes up - but that error code doesn't say what

    I had an 8GB 1st gen iPod in it's original box in storage and just took it out to hook it up.  Charged it overnight, plugged it into new Mac Book Pro and it was recognized as being an iPod in recovery but other identifying information was all indicated as "n/a" (so, unknown OS, etc).  Error code 1604 came up so I downloaded iTunes on the Mac Book and it is currently showing version 10.  But now when I try to restore the iPod, error code 1611 comes up and the troubleshooting doesn't tell me what else to try.  The USB connector that came with the iPod was also never used before - brand new also from the box so that should be fine.  I also tried a different USB port on the Mac Book.  Any ideas?

    Error 1611
    This error typically occur when security software interferes with the restore and update process. FollowTroubleshooting security software issues to resolve this issue. In rare cases, this error may be a hardware issue. If the errors persist on another computer, the device may need service.

  • Can't use my Adobe Illustrator CS2 with my new Mac Book Pro - is there any way to fix?

    I recently purchased a MacBook Pro only to find out AFTER I made the purchase that I would not be able to use my Illustrator CS2! Do I really have to purchase a complete version of CS5 or is there another way around this? Does anyone know if OSX 10.7.2 will work with any upgrades to CS2?

    There is no Rosetta support in Lion, and most likely there never will be. You will have to update to CS5.

  • Trying to install Deskjet 3054A wireless printing with brand new Mac Book Pro

    Hello,
    I am trying to set up the wireless printing function on the Deskjet 3054A with a new Mac Book Pro, but not having any luck. When I connect via the USB the printer shows up, but once disconnected there is no communication. I tried to get the updated driver on the HP site, but nothing ever downloaded and it kept taking me to the setup page. 
    Is this All-In-One compatible with the new Mac OS 10.10 for wireless printing?
    Thank
    Scott

    Hello Sabuff,
    Welcome to the HP Forums.
    I see that you are having some connectivity issues to you Mac 10.10.
    Just so you are aware, the printer does not have a full feature software and driver package available for the Mac 10.10 operating system.
    You can however try the HP Printer Drivers v3.0 for OS X.
    Please feel free to write me back with any other questions or concerns.

  • I have a new mac book pro which i use in england but I need to use German charachters frequently, is there a way of having both visable on the keyboard?

    I have a new mac book pro which i use in england but I need to use German charachters frequently, is there a way of having both visable on the keyboard?
    For example so that I can just press shift or another key to get the German character.

    Some may already exist, but you will have to learn them.  On my old system these can be found through keyviewer.app  For example, if I press option+s I get ß   Umlaut is a bit cumbersome as option+u then the actual letter.  It may be possible to bind a key to do this function, possibly through System Preferences > Keyboard > Shortcuts
    I have old, old references for utilities that let you rebind keys to other functions, and you would have to see if they have modern equivalents.
    Ukelele Mac OS X Keyboard Layout Editor - http://scripts.sil.org/cms/scripts/page.php?site_id=nrsi&id=ukelele - mostly useful for character, not function mapping.

    .. and by the way, the jump from FCP 6.0.3 to FCP 7.0 (or higher) isn't an "update"  It's a full version "upgrade" that has to be done using the install discs (or disc images).

  • I set up my new computer using the apple ID i always use, and then later migrated all my files from my old mac book to the same new one, but under a different user (same ID). how do i consolidate the two users on my new mac book?

    i set up my new computer using the apple ID i always use, and then later migrated all my files from my old mac book to the same new one, but under a different user (same apple ID). how do i consolidate the two users on my new mac book?

    Well if you use the Finder Go menu to Computer, a window opens up double click on your boot drive and then on Users folder, open the other user folder and open Public and drop your files into DropBox
    When you do this it will copy them and change the permissions and user assigned to it, so log into the other user and place them into your respective normal folders.
    Once you have all your files over and don't need the old user, use System Preferences > Accounts to delete it if you wish, however it's good two Admin accounts on the machine in case something bad happens in the other. Some people for security reasons on use a Standard account for most uses and a emergency Admin account.
    One can still do most Admin things in Standard user.

    " how can I sync my iphone to my mac book without losing all the music and pictures on it?"
    You cannot.  Copy everything you want form the old computer to the new one, then sync it.
    it basically says you have to erase your iphone to sync to a new itunes!
    Correct Iphone will sync, or manually manage, with one and only one computer/library at a time. Syncing, or manually managing, to another will indeed erase the current content.
