Connecting two 27" iMacs via mini DisplayPort

Juz a thought. Wonder if possible.
Since the 27-incher iMac does video input and output, instead of buying two 30" displays ($1799 each), might as well buy two of these 27" iMacs ($1999 each) and connect them via their mini DisplayPorts. Wonder if it's possible to use one 27-incher for computing and use the other as a second monitor, and switch around whenever it's needed. Kinda cool to have two 27-inchers and Macs on one table top.

There is no reason why that would not work. It would be the same as connecting a MacBook or a Mac mini or a Mac Pro (any Mac with a Mini DisplayPort) that same way to use the 27-inch iMac's big screen as a second display, which is the primary purpose of this feature. It should not matter if the primary Mac happens to be another 27-inch iMac.
And the second iMac would not be "just the display to extend my screen." It is fully operational, so it can be doing tasks in the background. It can be acting as a file or web server, or processing video, or downloading/uploading files. I believe there is a keystroke to toggle the display, and you can probably even control it using +Screen Sharing+ from the other iMac (as long as the two are connected over a network).
What would be really interesting to know, from someone who actually has two of these iMac sitting side-by-side, connected with a Mini DisplayPort cable, is if you can use either iMac as the extended Desktop screen for the other iMac, on-the-fly. So you'd be working on iMac A with iMac B being the second display. Then, you switch to the working on iMac B with iMac A being the second display. And do it with a few keystrokes and no rebooting. Now, that would be cool.

    You can connect the audio from your iMac to your TV using a mini jack (like headphones plug) to rca (regular red and white audio connectors used on every TV,DVD, etc) cable.
    On your TV, you need to be able to set the audio for the HDMI input you will use to "analog" and connect the rca end of the cable to the analog inputs on your TV.

  • NTSC monitor component/RGB to Imac via min-displayport

    I'm trying to hook up an NTSC monitor which only has RGB and component (Y, R-Y, B-Y) ports to my 2009 iMac, which thus must use a min-display port to do so.
    Does anyone know of the best way of connecting this NTSC monitor to my iMac? I had thought about...mini displayport/DVI-->DVI to component.
    Although mini displayport/VGA-->VGA to component might work too.
    One concern I had was that I heard the mini displayports were DVI-D opposed to DVI-I, which may or not mean a component adapter would work.
    help lol.
    thanks

    There was a long thread on the forum with good info regarding conversion of Mini DisplayPort to composite/S-Video.
    http://discussions.apple.com/thread.jspa?messageID=9692969
    I don't think component will work for the same reasons, unless you use something like the rather complex method explained in the post by Lougle in the above thread (the one with pictures). Maybe it is different...
    I thought of something the other day though. OWC has a recent USB video adapter product.
    http://eshop.macsales.com/item/Other%20World%20Computing/VIDU2DVIA/
    I wonder if you could put a DVI-to-component adapter (or a DVI-to-composite adapter) at the end of this USB-to-DVI adapter, and get it to work. I don't think the product description has the answer, and I was going to send an email to OWC's sales/tech support to ask. I'm only curious, since I don't need such an output myself. If you decide to ask them, please post back with their response.

  • 27: iMac Apple Mini DisplayPort to DVI adapter quits working post-firmware

    I iMac Apple Mini DisplayPort to DVI adapter suddenly quit working after I installed Apple's latest iMac display firmware update. This is an Intel Core i5; the monitor is an LG Flatron 24" Wide, and when it powers up it says "no video input" and goes into power-saving mode. No amount of replugging cables helps, but the monitor works fine on other computers.
    The Displays control panel just shows one monitor, and clicking Detect Displays does nothing.
    I suspect Apple's Display Firmware Update. My installer log shows the following, but the problem only happened today after the latest update:
    6/1/10 9:45 AM 27-inch iMac EFI Firmware Update 1.0
    6/1/10 9:45 AM 27-inch iMac Display Update 1.0
    6/4/10 11:47 AM 27-inch iMac SMC Firmware Update 1.0
    6/4/10 11:47 AM 27-inch iMac Display Update 1.0
    6/5/10 7:29 AM 27-inch iMac Display Update 1.0
    I have automatic updates disabled, but after each update I would see more firmware updates ready, but caution leads me to never install more than one of these at a time, and then to wait a while to see if anything bad happens. The odd thing is that the Display Update 1.0 seems to have been installed three times in this course of events. Alas, there appears to be no way to uninstall a firmware update.
    Here is the System Profiler Graphics/Displays output:
    Chipset Model: ATI Radeon HD 4850
    Type: GPU
    Bus: PCIe
    PCIe Lane Width: x16
    VRAM (Total): 512 MB
    Vendor: ATI (0x1002)
    Device ID: 0x944a
    Revision ID: 0x0000
    ROM Revision: 113-B9110C-425
    EFI Driver Version: 01.00.383
    Displays:
    iMac:
    Resolution: 2560 x 1440
    Pixel Depth: 32-Bit Color (ARGB8888)
    Main Display: Yes
    Mirror: Off
    Online: Yes
    Built-In: Yes
    Connection Type: DisplayPort
    Display Connector:
    Status: No Display Connected
    It says the Mac sees no display connected, and the display gets no video signal. Since the adapter is an active device (it has powered electronics to convert DisplayPort signals to DVI signals) I suppose it could have just coincidentally died. But that seems unlikely given that the thing worked perfectly just before the last firmware update.
    Does anybody have similar experience, or better yet, a fix?

    Unfortunately the Apple Knowledge Base does not give much information about this update. Such has how to tell if it has been successfully installed. I suspect that because it keeps recurring in the install log that it has not been installed successfully as yet. Are you receiving this update through Software Update? Can you locate the installer for this update? It maybe located in Apps/Utilities.
    Some firmware update installations can be interrupted/corrupted by attached devices. If you find the update's installer on your iMac, I suggest that you detach all external devices from the iMac, use an Apple USB keyboard & mouse if available, follow the instructions carefully and install the update manually. If you do not locate the installer I suggest downloading manually from the link below and installing it.
    The Knowledge Base article mentions that your iMac should also have a Graphics Firmware Update. I suggest that you download and install that as well.

  • Connect two external monitors to mini DP(using a mini DP to VGA adapter) and the VGA out at once

    I am trying to  connect two external monitors to mini DP(using a mini DP to VGA adapter) and the VGA out at once. Windows recognize both monitors as well. But it dowsn't let me use all three monitors at once(see the below image). In the dropdown, it lists all three monitors. Problem is there are two active displays I can select.

    Mavec wrote:
    I would like to add a third monitor.  
    The GPU(s) in your T400 (and most other laptop brands) will support two different displays concurrently.  If you want to support more than two different displays concurrently, you will need another GPU external to the T400.
    Generally, if you want to use two external displays on a T400 you will nee dto use a docking station.
    I have read messages on various fora on this topic and know that there are a number of ways of doing this, but as I have never had a need to do this myself I can't tell you how to go about it.

I have tried going to display setting but cannot find the arrangements tab. When i searched "arrangements" a message said, "The Arrangement tab of Displays preferences is hidden because you only have a single display attached to this computer." Not sure how to fix this problem. I have connected this laptop to a TV before, but with a different cable other than the one i just purchased. Any help would be greatly appreciated, thanks.

    Found the fix.  Still don't know if it was Windows, iTunes, or Norton 360, but this worked immediately for me:

  • A printer that I have connected to my iMac via usb in not showing up in printer options on my iPhone or iPad and it use to before I upgraded to 8.1

    A printer that I have connected to my iMac via usb in not showing up in printer options on my iPhone or iPad and it use to before I upgraded to 8.1. How can I fix this?

    Is it an Airprint-compatible printer, and is its WiFi enabled if it is? (see: About AirPrint)
    If it isn't an Airprint supported printer, then you need a 3rd party driver on your iMac to print from an iPhone. Such as Printopia. As it worked in the past you probably have such a printer driver installed; check and see if it's running.
    Beyond that try restarting the printer, restarting the phone, restarting your router, and restarting your computer.

  • Connecting Two Airport Express Via Ethernet

    I have a unique situation in which I would like to connect two airport express via ethernet. Here is the situation: I can connect the first AX directly to the internet and set up a WDS for the second AX. Unfortunately, the second AX signal does not reach where I need it to go. I can run an ethernet cable between the two. Is this setting valid for a WDS? Or does the WDS have to be wireless? If I can set up the WDS using an ethernet, will the relay AX broadcast the internet wirelessly then?
    Are there any specific settings I should know about?
    Any help would be great.
    Thanks in advance,
    Debbie

    I currently have an old snow basestation at this location. Can I plug an ethernet cable into it and connect it to the AX?
    Yes that will work.
    My understanding was that the older basestation could not do this?
    I think you have it confused with extending a network wirelessly. That is not possible with the snow AirPort base station (ABS).

  • IMac 27" (Late 2009): getting audio to HDMI receiver via mini DisplayPort

    I just got my first iMac 27" and I'm in the process of integrating it into my home theater system. Here is my setup:
    iMac 27" connected to HDMI receiver (Yamaha RX-V1800) via mini DosplayPort, using miniDP-to-HDMI adapter + HDMI cable
    Optoma HD20 video projector connected to HDMI receiver (HDMI out) via HDMI cable
    I have Windows 7 installed via Bootcamp 3.2, so that I can take advantage of Windows Media Center. With the above setup, I am not getting audio or video signal to my receiver and video projector when I'm using Windows 7. However, when I am in OS X environment, I can get both video and audio signal to my receiver and video projector, and either mirror or extend my video diplay. When I do plug in my iMac straight into my video projector or LCD monitor with built-in speakers while in Windows 7, I get both audio and video output. So why doesn't it work -- and only under Windows 7 -- when the signal goes through the receiver?
    My immediate thought was that it must be something about the receiver, but since the setup creates no problem under OS X I don't think it is. Could it perhaps be the Windows driver for mini DisplayPort, because it looks like iMac is not 'recognizing' my receiver and therefore not establishing connection? Is there a driver of fix available that takes care of this problem?
    Thanks!

  • Connect 24" Cinema Display with Mini DisplayPort to new 21.5' iMac

    I'm having a bit of an issue attempting to connect my new 21.5' iMac to my Apple Cinema Display. The display has a mini DV port that used to connect into my MacBook Pro but now I see there is no such port on the iMac.  They clearly state they offer support for it but I don't see a way to connect. Any suggestions?

    19. 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 14), 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.

  • Connecting my macbook pro 13" to Sony bravia via mini Displayport to HDMI

    Hi,
    yesterday I bought a new LCD TV Sony Bravia KDL-32EX600 (Full-HD LED) that has 4 x HDMI inputs.
    I also bought a mini Displayport to HDMI and HDMI to HDMI cable.
    When I connect it to my computer, the screen goes blue for a second and it doesn't recognise any additional displays. There's also no video or sound in the TV, on the right HDMI channel. (I've tried every HDMI input and every channel)
    I've tested the TV with another laptop that has straight HDMI output from the gfx card and it works perfectly.
    I have up-to-date MacOS and I also upgraded my TV's firmware to the latest.
    I thought that maybe the miniDisplayport to HDMI connector is broken but why does the computer try to do something when I turn on the correct channel on the TV?
    I'm out of ideas..

    Hi madhenry,
    I know it's a month on from your post, but I thought I'd add that I'm having exactly the same problem. I'm trying to connect my new MacBook Pro (15" core i7) to my Sony Bravia KDL-40EX600 using a mini displayport to HDMI adapter. When I plug the cable in, the MBP screen goes blue for one second then goes back to normal, but the system just doesn't detect the external display.
    I've tried the MBP on other monitors and it works fine, so there is nothing wrong with the adapter or cable.
    I've also tried plugging two other Macs into the TV (a 2008 15" MacBook Pro and a 2008 MacBook) and the TV works great with both of them.
    So, it seems there's something specific to the new MacBook Pros that makes them incompatible with the Sony EX600 TVs.
    I just talked to AppleCare about it and after trying a few things (resetting the PRAM, etc.) I was simply told that there's nothing wrong at all with the Mac and that this is simply a "compatibility" issue that I have to put up with. So, it looks like we're out of luck until (hopefully) a new Mac OS update fixes the issue.

  • Connect Mid-2009 Macbook Pro to HDTV via Mini Displayport to HDMI adapter

    Hello,
    I'm trying to connect my Mac to my HDTV via a Mini Displayport to HDMI converter I bought at the Apple Store. I have tried on three different HDTVs, none of which allow me to output video. I have tried adjusting the resolution to every available resolution under system preferences. Any advice as to how to resolve this problem would be very much appreciated.
    Thank you,

    I'm having the same problem, also with a 2009 13" MBP and a Mini DisplayPort to HDMI adapter.  Does anyone out there have a solution?  Do we need a different kind of adapter?  My tv is a Samsung 720p.  My boyfriend can connect his PC laptop with an HDMI cable with no issues.

  • Can I watch an iTunes movie rental on a TV connected via mini displayport?

    I'm not sure if there's been any headway with this, but I've got a mini displayport to HDMI adaptor on the way that I'm going to use to connect my MacBook Pro to my HDTV, effectively using the TV as an external monitor.
    And of course, I want to watch some iTunes movie rentals on the TV instead of my laptop, but digging around the internet has shown that I might be facing an issue relating to the HDCP standard that would prevent me from being able to use my TV in this manner.
    Is this still an issue? I have a fall 2009 MacBook Pro, which may be important, as I've read that Apple modified the mini displayport on the MacBooks in 2010.
    Other than renting a movie as a sort of guinea pig with the possibility of being shot down and wasting my money, is there any way to know if this is going to work? Or is it simply a fact that any monitor/TV connected to my MacBook through the mini displayport is incompatible with HDCP, and I'm totally out of luck?
    (Which, FYI Apple, is utter horse **** and is absolutely counter-productive to the notion of encouraging me to pay for digital entertainment.)
    What are your thoughts, folks?

    If your HDTV is HDCP compliant, you probably will have no problems. But you might want to read this information which while written a while back still, to the best of my knowledge, applies:
    http://www.ilounge.com/index.php/articles/comments/16488
    HDCP compliance is, from what I've read, rather a "rubber ruler" so even if your TV lists as being HDCP, it might or might not work correctly with your Mac. Testing with one movie first might avoid an expensive surprise.
    As to your complaint to Apple, it probably wasn't up to Apple but instead was forced on them as part of the conditions by the content owners for licensing movies and shows to the iTunes Store. But feel free to comment to Apple via their feedback pages:
