Connecting two 23" displays

The Mac Pro has one firewire 400 port and one firewire 800 port. Each display has a firewire 400 connector so there is no available firewire 400 port for the second display. Is it OK to connect the second display firewire cable into the first dispay's firewire port?

Why don't you simply get yourself a FW400 (6-pin) to FW800 (9-pin) cable and connect your 2nd display to your FW800 port.

  • Connecting two extra displays

    I was wondering whether it would be possible to connect two external monitors to my macbook. I currently have one connected but would like to add another- any help?

    It's possible that you could get what you're after.
    You'll need an external hardware that can split your display output. There are third party solutions for PC's - even for desktops that don't have internal PCI/AGP/PCIe expansion.
    Matrox has a LONG standing history at providing solutions for Windows. Actually I just took a look at their site and saw "Matrox DualHead2Go DisplayPort Edition"
    Specifically I read: "Run two monitors from your notebook or desktop computer even if that system only supports one monitor output" & "Includes Matrox PowerDesk software for Windows and Mac"
    Be careful though. Currently I saw lack of support for 10.6.
    "Mac® OS X v10.4, Mac OX v10.5 Leopard"

    Take a look around to see their competitors which has begun to flourish in the past 3-5yrs.
    Hope this helps.

  • Tecra A9 - Connecting two external displays using Express Port Replicator

    Hi,
    I have a Tecra A9 and Express Port Replicator.
    I'm trying to connect 2 external displays, one connected on the notebook output and the other connected on the docking station (notebook lid closed, not using the notebook display).
    I can only get one to work, does anyone know if this is possible?

    Hi
    I think you want to connect one monitor to VGA and the other to DVI port.
    Is it right?
    Well, I found this doc:
    http://aps2.toshiba-tro.de/kb0/TSB7B0201000CR01.htm
    It depends on the used Tecra A9, if you can get a picture on the DVI out port on the Express Port Replicator (PA3508E-1PRP) or not.
    The DVI port on the on the Express Port Replicator is only supported on machines with ATI or nVidia graphic card.
    If you have a INTEL graphic card the DVI port on the on the Express Port Replicator is NOT supported.

  • How tow connect two external displays that are not mirrored and turn of the retina display

    Hello,
    I have two questions:
    1.  Is it possible to use two external displays either mirrored or not and turn off the retina display, and if so how it is done?
    2.  Is it possible to close the MBP and use an external keyboard while using two external displays?
    I am using a music production DAW Persons Studio One-2 Pro and it would be great to be able to have this type of a setup.
    Thank You,

  • Possible to Connect Two External Displays?

    At work I have two 1600x1200 LCD displays connected to my G4 MDD and I've become quite attached to them and truly feel the extra real estate increases my productivity.
    I'm due to get a new system and would like to get a laptop rather than a desktop system since I occassionally work from home and would like to just have one machine for everything.
    The only thing holding me back is the unavailabilty of using dual displays. Here are the only solutions that I know of, but not that I am interested in:
    o use the laptop display with an external display (problem: I would want my two displays to be the same size, and the laptop display would be too small for my taste)
    o use one of those matrox dual display external boxes (problem: uses vga but my LCDs are DVI and I'm not interested in sacrificing quality)
    o get a huge display to take the place of two, like the 30" ACD (problem: too expensive, and already have two nice 21" displays)
    So ... just hoping someone has some other suggestions. If nothing like this is available now, does anyone know if this sort of capability would or could ever be supported? Thanks.

    Thanks for the quick reply, but see my second bullet, that what I meant by the "matrox thing". If it were DVI based I'd give it a try, but my understanding is it is VGA.

  • Connect two U2515H displays to Vostro 460.

    I recently aquired two of Dell's 25" U2515H displays. I would like to know how I would go about connecting those up to on of Dell's  Vostro 460 mini towers (from 2011, i5 3.1 GHz, 4GB RAM, onboard HDMI). 
    What, if any, (2x DP) GPU expansion card will fit the Vostro, and allows me to connect both displays? I'm not at all interested in gaming, so performance is not really an issue, as long as an OS runs smoothly, I'm more than happy.
    Thanks.

    You do not need to add a PCIe x16 video card. If you did, remember the Vostro 460 only has a 350w power supply. These are the Dell validated OEM video cards =
    8F60V AMD Radeon HD6670 M208
    HWHRN AMD Radeon HD5670 M206
    KP8GM AMD Radeon HD5450 M114A
    U2515H video in ports = HDMI/HDMI/DP/mDP
    Vostro 460 video out ports = HDMI/VGA
    Vostro 460 HDMI out --> HDMI to HDMI cable --> #1 U2515H in
    Vostro 460 VGA out --> VGA to VGA cable --> VGA to HDMI active converter --> HDMI to HDMI cable --> #2 U2515H in

    Hello tonnyfromholsted,
    Great question. Your MacBook Air includes one thunderbolt port. Each thunderbolt port can support up to one Mini Display Port display. Thus, your MacBook Air can only connect to one external display. Even when taking Thunderbolt Displays into consideration, this Mac still only supports one connected display. For more information, please refer to the following resource:
    Thunderbolt ports and displays: Frequently asked questions (FAQ) - Apple Support
    http://support.apple.com/en-us/HT204154
    2. How do I connect my Mini DisplayPort monitor or monitor using a Mini DisplayPort adapter to my Thunderbolt-equipped Mac when I have other Thunderbolt devices connected?
    When connecting a Mini DisplayPort display or a display using a Mini DisplayPort adapter to a Thunderbolt peripheral (except as described in question 24), make sure the display is connected at the end of the Thunderbolt chain. You can use only one Mini DisplayPort device in the Thunderbolt chain.
    Note: Systems with more than one Thunderbolt port, like an iMac, can have more than one Mini DisplayPort monitor or monitor connected with a Mini DisplayPort adapter connected as each Thunderbolt port can support one Mini DisplayPort display.
    Thanks,
    Matt M.

  • Any way to connect two external displays?

    Hello,
    I have a quick question about connecting my PowerBook G4 15'' (machine model: Powerbook 5,6) to some external displays.
    I am trying to connect it to both a Samsung Syncmaster LCD and my TV.
    Currently, I am able to connect to each successfully, but only one at a time.
    My Samsung syncmaster LCD is connected via the DVI port on my powerbook, and using the DVI to VGA adapter, since the Samsung LCD is VGA. My TV is connected via S-Video, though I do have the s-video to composite adapter that came with my powerbook if it makes a difference.
    Anyways, my problem is I want to be able to use all three displays at once (the powerbook screen, my samsung LCD, and my TV), but i can only get one of the external displays working at a given time, and have to unplug the DVI (samsung lcd) to get the TV to be detected and activated as an external display.
    Any suggestions will be much appreciated. If there is some adapter I need to buy to make all this work, thats fine, just tell me what it is.
    Thank you for all your time.
    Regards,
    Matt Ellison

    This solution was previously pointed out to me on the 17" PowerBook forum. I don't have one and don't know how well it works. Last I saw they didn't have drivers for Tiger, yet.

    I expect you would hook your SyncMaster LCD to the VT Book and then use the S-Video port on the PB to connect the TV.

  • Using FCP 7 - Can I connect two more displays to the new 27" iMac and have one as a display monitor?

    I use Final Cut Pro 7 right now and am thinking about buying the new 27" iMac with the NVIDIA GeForce GTX 780M 4GB GDDR5 card. I have a 24" Apple Cinema Display with mini Display port cable. I also have one more Samsung display with DVI & HDMI. Can I connect both monitors to the iMac and be able to use one in FCP as a display monitor?

    Hello,
    Maybe a device like the Targus USB 3.0 SuperSpeed Dual Video Adapter or StarTech USB 3.0 to HDMI an DVI Dual Monitor External Video Card Adapter would work?

  • 27 inch iMac (April 2011) - Two external displays - how?

    I've just got a new 27" iMac and have connected two external displays via the mini display port. I can only get one to work, what am I doing wrong?

    Sorry that was a dumb typo on my behalf. Here is the setup:
    Apple 27inch iMac only bought today, so it's the newest version with the two Thunderbolt ports.
    Two seperate external monitors each connected to a seperate port via a DVI cable and Mini DisplayPort to DVI adapter.
    So that's:
    iMac x 1.
    Thunderbolt port x 2.
    External Monitor x 2.
    Mini DisplayPort Adapter x 2.
    3 displays in total. But when I turn on both displays only one will show up.

  • Connecting external VGA displays

    I am attempting to connect two external displays to my 15" early 2011 macbook pro. One is a Dell monitor and the other is a Hanns-G. Both are pretty old and only have VGA ports, but I know for a fact both the monitors work because I was using them on my old desktop. I already own a rocketfish mini displayport to DVI adapter so what I did was I purchased a male DVI-I to 2x VGA splitter. So basically the setup starting from my macbook pro would be mini displayport>DVI>DVI-I splitter>2xVGA monitors. For some reason when I use this set-up though, the monitors do not connect and instantly go into sleep mode. I've tried going into display preferences and detecting displays, but no luck.
    Here's where things are odd. I tried on my friend's monitor, an HP with DVI and VGA ports, to connect the DVI directly to my DVI>mini displayport adapter. That works fine. But when I try to connect through the VGA port on the monitor using a VGA to DVI adapter, and then DVI to mini displayport, the monitor instantly enters "sleep" mode when I plug the mini displayport end into my macbook pro. Since all three monitors entered sleep mode, what I'm assuming is that the right signals are not being converted between VGA and DVI, or something along those lines. Is it even possible to use a splitter cable with the DVI to mini displayport adapter? The signal must be getting screwed up somewhere along the way. But then again, I have no idea. If anyone has any ideas, or any settings I could fool around with on my macbook, it'd be much appreciated!

    Hi,
    HDMI to VGA cable won't work, you need a converter to convert from digital to analog. The following device is one example:

  • Connect 2 external Displays with a iMac 27''

    Hi,
    is there a way to connect two external Displays with a iMac 27inch. Eyefinity? Its a Radeon 5750 inside the iMac isnt it?

    Hi,
    For the first screen is no brainer you use the Apple adapter to have video out to HDMI or DVI, but the second screen is where it gets tricky...
    There are USB to DVI out external video cards that should work with the iMac and OS X 10.6 but I have changed. Honestly I have tested 6 so far and none of them works as advertised, you can not even set minimal resolution on there and some wont even work ( all of them come with OS X 10.6 drivers )
    So I will recommend to stay away from the small $70 or $90 external USB to VGA/DVI cards...
    (maybe someone has luck with them but i have tried like I said 6 so far different brand and no luck..)
    Now recently online I tripped over a nice external video card that takes the MiniVideo Port out from the Mac and then takes it to another 2 monitors price was $249 i think, and you could hook up 2x30" monitors with hight res... I will try to find this link and post here later on.

  • Two External Displays and Internal Display Over Different Connections

    Hi there.
    I'm going to be purchasing a rMBP in the very, very near future. However, I am unclear about how external displays work with this. My current display setup at work is two basic 1080p monitors that can be run over DVI, VGA or HDMI. I'd like to keep using these when I start using the rMBP but also gain the advantage of a third screen by using the internal display at the same time (so much space for activities!).
    One of the thunderbolt ports will need to be used for an Ethernet connection (there is no wireless here), so this leaves the setup needing to be one monitor run via Thunderbolt -> DVI and the other monitor run via HDMI.
    The internet in general isn't being entirely helpful with this. I'm looking for a clear answer of whether the rMBP will run the internal display and the two external displays using this setup under OS X. Some seem to believe that it won't work using different connection types, for example.
    Thanks for any help.

    Hello dljfield,
    Thanks for using Apple Support Communities.
    If you'd like to use multiple external displays with a MacBook Pro with Retina display, then please take a look at the information outlined below. A 15" MacBook Pro mid-2014 can support up to two external displays using different outputs.

  • Can I connect two non-TB external displays to a new MBP?

    Looking to pick up a new MBP and I would like to connect two non-Thunderbolt monitors, they are nice but WAY too expensive, and I'm wondering if this is possible.  I know I can use Matrox Head2Go line of products, but I would like to avoid shelling out another 2-300 on other hardware if I can avoid it. 
    So any other ways to drive two monitors?   I'm surprised there is no Thunderbolt -> DVI adapter or something.  Heck maybe there is, but I haven't seen it yet.
    Thanks

    here is the adapter your were looking for http://store.apple.com/us/product/MB570Z/A
    you'll also need to consider getting something that supports usb to dvi which will make your third monitor connnected via a usb port. This uses DisplayLink Drivers which let you connect a monitor via usb. Warning, it does not have full support for Lion yet.
    I'm using the arkview usb display adapter. there are other on the market, they all use DisplayLink. And since I'm on Lion I'm waiting for DisplayLink to fix their drivers to work on it (it's been a struggle).
    If you're on Snow Leopard it will do you well to stay on it. .
    you could get on Thunderbolt display and then connect a monitor to that with the dongle I showed you. Then you will have no issues with Lion and your three displays.
    Thunderbolt tech is new and new adapters will be coming out for it, especially something that handles mutliple screens. but you'll have to wait for this technology to be made.

  • Connecting Two Displays

    I now have two Cinema displays that I would like to connect to my G5. Where the DVI ports are I'm short one FireWire port since both displays require a USB and FireWire connection along with the DVI.
    Can someone suggest a good way around this to allow for two displays? Is there such a thing as an extension for a FireWire cable that I can then run to the other side of the G5 where there is another FW port? The problem with this is that I have no FW ports left on the G5. Do I run any risks if I try to daisy-chain my display's FW to a port on one of my external hard-drives?
    Do FireWire hubs exist and are they reliable? I could be overlooking something with regard to connecting two displays as I'm sure it's done all the time. I'm just not sure about the best way to proceed. Thanks for any info.

    There are FireWire hubs and extension cables, but
    unless you need to use the FireWire ports on the
    displays, you don't have to connect their FireWire
    cables.
    I'm in the same situation as Stuart - I'm short one Firewire port.
    I tried plugging a powered Firewire Hub into the back of my new G5, and then tried plugging the 2 ACD Firewire cables into the hub - the G5 crashed on Startup.
    Surely there has to be more support info "out there" than "There are hubs & extension cables...
    Can we plug a Powered Hub into ACD #1, then plug the ACD Firewire cable into the Hub?
    Is it safe to use an Extender/Repeater?
    Is there a "Splitter" available, and it it safe to use?
