Dual 27" ACDs with MacPro

I am trying to set up 2 new 27" Apple Cinema Displays with an older MacPro. I have the default video card with 2 DVI-D Dual link outs ( female ). The ACDs have only the Apple Mini Display ( male ) for connection. For the life of me I can't find the proper DVI-d to Mini Display adaptor - everything I find is female.
Can you kind folks point me in the right direction ?

Yes, 2720QM.
I have to admit just to get the WQXGA res working with discrete-only graphics requires an arcane series of steps to reboot, connect cord, power on monitor in a specific order or not only does it not work, it permanently does not work until I cold shutdown the laptop/monitor.
As per discussion here http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/T520-and-WQXGA-2650x1600-resolution-with-Ac...
Possibly getting WQXGA going in integrated/optimus mode requires an even more occult ritual which I haven't figured out yet.

  • Dual 20" ACD with Geforce 6600

    Hi, is anyone here using dual 20" ACDs with the 6600? I have the stock 6600 in my dual-core 2.3. I read in another thread that performance wasn't great, but that was in relation to Aperture.
    What's performance like otherwise? I'm thinking in terms of Final Cut and After Effects, applications that aren't GPU-intensive, but experience with similar would be useful.
    Thanks!

    The main issue with driving two displays is that it divides the video RAM between the displays. So, your 128MB card acts like two 64MB cards. This isn't likely an issue unless you're playing games or doing something that needs to load textures onto the video card (e.g., Aperture, Motion).
    There shouldn't be a noticeble difference in Final Cut since, as you know, it isn't currently GPU accelerated. After Effects, on the other hand, can use the GPU to accelerate previews, depending on the version of AE that you have.

  • 2.26 8 core with GeForce GT 120 & dual 30" ACD, what to do?

    I'm almost getting the new 2.26 with the standard GeForce GT 120 card, now I need to use dual 30" with the new machine & I'm currently using the dual 30" setup with my 1st generation 2.66 quad with GT8800 & everything running smoothly. How I can do the same setup ?
    1. Can I install my GT 8800 card (1st generation) in my new 2.26 early 2009?
    2. Can I add another GeForce GT 120 so I can connect each monitor individually to cards?
    3. Buy the dual link mini display adapter & use only GeForce GT 120? (I don't like adapter idea)
    I need your advise for this & I'll be using the system for photography (aperture)

    No. You would need the 8800 made for the 2008 Mac Pro.
    2. Can I add another GeForce GT 120 so I can connect each monitor individually to cards?
    Yes, but some operations are faster if both displays use the same card.
    3. Buy the dual link mini display adapter & use only GeForce GT 120? (I don't like adapter idea)
    That should be best.

  • Dual monitor setup with seperate resolutions

    hey guys!
    i currentley run thye latest version of archlinux with the cinnamon desktop environment and an nvidia geforce 7300SE graphics card.
    im running a dual monitor setup with one 27" 1920x1080 monitor and one 27" 1024X768 monitor
    because they have the same physical size they line up perfectley but because the resolution is different programs/mouse cursor movement doesnt, is there any way (without changing the resolutions) to compensate this effect so that in the eyes of linux/cinnamon the monitors line up so that for example dragging a window goes seamlessley between the 2 monitors.
    i HAVE found out the panning option in the nvidia x server settings, but that really isnt what i am looking for...

    A magnifier following the window down to the pixel, zooming to the exact size of 540 pixels the 384 pixels window could create an illusion of just that. It would be highly impractical however, not mention all the hacking time. Even if you would manage to get two screen with different sized icons, so that they match visually, the windows and fonts resizing on the fly, wmctrl might help with windows alone, no their themes (buttons, borders thickness etc.), you would still be left with a visually differently sized mouse cursor. Technically such a feat should be possible, but who is going to code it? Nvidia?

  • Dual-DMVPN Design with Dual Hubs on a single router ??

    Hi All,
    In DMVPN, in Dual-DMVPN Design with Dual Hubs , can a single router perform the role of dual hubs.
    The router has two different internet links. It is intended that when one link goes down, spokes shud connect to the same router onto the other active internet connection. Is this possible ?

    Since no one has answered yet, I'll give you the practical answer.
    You'll have issues with IPSec and static routing. "DMVPN" itself probably wouldn't have an issue, but it would depend on IPSec and routing to work.
    It is easier, by far, to put in a second router. And when you factor in your time to try to make it work (and it may not work), the second router is less expensive.

  • HOW TO DUAL BOOT W540 with windows 8.1 / 7

    I got my W540 recently with windows 8.1 pro on it. but as all engineers worst nightmare windows 8 has hard time with engineering softwares (for my case TIA Portal for  PLC programming software which only support windows 7). so i need to have a windows 7. i prefer to keep my windows 8 and have dual boot system with windows 7 added. But i can't install windows 7. initially due to disk type (GPT), then i changed it to MBR without losing my files (which only was possible if i had deleted the recovery partition- now my recovery is on my flash drive). But there are already 4 partitions on the system (1 for C: drive and 3 for recovery and system files which came originally with the product) , how can i install a windows 7? i can't add another partition because that makes my disk a Dynamic disk (which i don't really know what is). all in all, i really need windows 7 on my system ASAP.  If anyone know how to fix this please reply. Thanks guys.
    Solved!
    Go to Solution.

    You are limited to four PRIMARY partitions on an MBR disk.
    But other than the "active" partition (i.e. the small 100MB "system reserved" partition where Boot Manager is placed from doing a cold Windows install on an empty drive, or the 1.4GB equivalent Boot Manager partition that Lenovo provides along with other tools and utilities), all other partitions on the drive can be "logical".  They are not required to be PRIMARY, although Lenovo delivers its partitions that way.  But you can change that.
    You can have up to 120 LOGICAL partitions on a drive (all of which live inside an originally PRIMARY partition which gets converted to an "extended partition" which houses all of the logical partitions.  So if you have at least one logical partition (and thus have to give up one primary partition in order to build that required "extended partitions"), that means you can have up to three remaining primary partitions and up to 120 logical partitions... all on an MBR disk.  No "dynamic", and no GPT.
    Yes, that means even the Windows system partition itself (i.e. "C") can be on a LOGICAL partition.  It's only that one "active" partition (where the BIOS goes to find Boot Manager and its menu, and kick off the rest of the system boot process) which truly must be PRIMARY.  That's the only requirement.
    So, if you want to use MiniTool's Partition Wizard to carve out sufficient free space for your second Windows 7 partition (by shrinking your existing Win8 partition), you can create one or more logical partitions inside that new free space, and do the Win7 install to one of those empty logical partitions.  You can then use a second logical partition in that same free space for "data", if you want.
    Note that Partition Wizard can even convert one of your existing primary partitions to logical (i.e. convert it to an "extended partition", inside of which will be then be the original primary partition now converted to logical).  You can then shrink or move/resize the partitions on the drive (both primary and logical) however you want, to perhaps make room for additional "logical" partitions inside of that now present "extended partition" which can hold up to 120.  You can even convert ALL of your primary partitions except for the one "active" partition (which MUST BE PRIMARY) to logical partitions, which gives you maximum flexibility in having even more than just two bootable OS's along with one or more data partitions, etc., up to 120 logical partitions... plus the one "active" primary Boot Manager "system reserved" partition which must be kept.

  • Can I dual boot Mac with Windows?

    Hi all,
    At the moment I have Windows 7 32 bit OS. I've always wanted either an iMac, or atleast the Mac OS. I've recently found out it's only £20.99, and i've always thought it was a lot more than that, which is a bargain! The only thing which is stopping me from buying it at the moment, is that certain programs which I use reguarlarly won't work on Mac, and I really need those programs. Is their anyway I could dual-boot it with Windows 7, so I give Windows 7 say only 8gb of my hard drive, and Mac the rest?
    I will appreciate any answers, and thanks for tackling this for me!

    Is an Intel Mac just an Intel Processor, with Mac OS?
    Yes Macs changed to Intel Processors in about 2007. You can upgrade as far as Lion with a Core2Duel Processor or better. CoreDuos will only update as far as Snow Leopard.
    Hope this helps

  • Dual External Monitors with 15" MacBook Pro (Late 2011)

    I'm looking for suggestions for using dual external monitors with new MacBook Pro's.  The company I work for has started to puchase these for certain employees and we are looking for any good suggestions.
    It appears that the display/thunderbolt port should be able to support many devices but I have not seen any way to hook up multiple displays.  The idea is that these employees would be working with the macbook pro screen closed while in the office and use dual displays.  The only option that I can find is to use a usb device to output video to a second display.  I don't really like that because my experience with these devices is that they usally present a display lag and I know our graphic designers would never go for that.
    One employee suggested that he use the VGA adapter and then get a VGA splitter.  I'm not exacty certain that would work though. Wouldn't that just mirror the display on two screens instead of allowing an extended desktop?  Also it looks like expensive Apple displays have ports so that you can daisy chain thunderbolt devices out of those monitors but this company will not go for the cost of those displays.
    Am I missing anything?  Any suggestions would be helpful.
    Thanks!

    Look into the Matrox Dualhead2Go DP Edition. If it works with Thunderbolt Macs, it will support two identical 1920 x 1080 DVI monitors as one extended desktop. Verify with Matrox that it is Thunderbolt-compatible and will suit your purposes before ordering.

  • Does LR handle a dual monitor setup with different aspect ratios (16:9 and 16:10)?

    Does LR 5 handle a dual monitor setup with different aspect ratios (16:9 and 16:10)?
    I'm planing to buy a 27" 16:9 monitor and use it as primary together with a 22" 16:10. Does any have any idea?
    Thanks

    Moreover, the two monitors can have completely different characteristics.  As always, you really need to calibrate/profile any monitor (with a hardware tool - Spyder, Colormunki etc).  That's no more important with two monitors, but you see for sure if you don't, as two dissimilar monitors will then probably look different. 

  • T410 Dual monitor support with integrated graphics

    I am considering purchasing a T410 with integrated graphics, but I need to make sure it will support dual digital displays (with a dock of course).  I use a T500 for work, and when I switch to the integrated chip, I am unable to use dual monitors.
    Can someone confirm that the T410 (integrated graphics) can use dual digital displays with a dock?

    Should work. That NEC is 1920x1080 which is suported on the single-link DVI. DP can handle even more. The dock has both DVI and DP. Your ThinkPad supports the 2 monitor outs. My understanding is the ThinkPad LCD would need to be off when you do this; the specs on the dock mention max 2 monitors simultaneously.

  • Doe's the reconfigured mac mini with the 3.0GHz Dual Core i7, with 3.5GHz Turbo Boost, run at 7200 rpm?

    Hello there.
    Doe's the reconfigured mac mini with the fourth generation 3.0 GHz Dual Core i7 with 3.5GHz Turbo Boost, with 1TB Fusion Drive, run at 7200rpm?
    Thanks.

    Historically Apple have generally used 5400rpm hard disk drives and while the detailed information on the Apple store does not definitively say what speed hard disk the 1TB Fusion drive includes, it does make mention of testing conducted with a 5400rpm drive.
    Therefore I think we can safely assume it does come with a 5400rpm 1TB hard disk. However this is not necessarily as bad as it sounds, the whole point of a Fusion drive is to automatically off-load the most commonly used files to the much faster 128GB SSD portion of the Fusion drive so overall you should get performance better than even a 7200rpm hard disk.
    Finally, as far as I can see for the Mac mini it does not matter which speed model you buy they will all come with the same 1TB drive model if you chose a 1TB capacity, so the 3.0GHz Dual Core i7, 2.8GHz Dual Core i7, and 2.6GHz Dual Core i5 will all have a 5400rpm 1TB hard disk.

  • Dual-Screen Sessions with Oracle Desktop Client

    Dear All,
    I have read that the new version of the SRSS and SRWC support dual-screen separation with Windows 2008 R2 sessions, i.e. Windows sessions are able to determine that they are running on a dual-screen device and allow separation as you'd expect on a fat client. Does anyone know if this functionality is available via the Sun Ray software client or if I'll have to invest in Sun Ray 3 Plus devices? Has anyone actually got this working at all?
    Many thanks.
    Chris

    OK. I've applied patch -05 to the SRSS (which is odd because I thought I'd downloaded 5.1.1) which installed without complaint and have upgraded my copy of the Mac OVDC to 2.1.9.
    I've run the command (see previous post) and now I can't seem to connect to the SRSS with or without a card - it's not even connecting to the server to get a pseudo session.
    What version of the SRSS patching comes with the 5.1.2 download? It's very confusing with the version numbers not correlating. 5.1.1 seems to come with patch -06 but it refuses to install...
    Many thanks.
