Extended Desktop via 1 HDMI possible ?

Hi, I have a late 2013 MacBook Pro w/Retina Display 15” Quad Core 2.6Ghz i7 with 16Gb ram.
Running the latest OS (10.10.3) and all latest updates, etc..
I have 2 23” Apple Cinema Displays which are DVI. I would like them to be used as “Extended Desktop” style on this computer.
I understand this is possible via the Thunderbolt ports (correct?), but would ideally like them to come out the HDMI port (and work like “Extended Desktop”).
This is because I will have the bandwidth of my Thunderbolt bus maxed out. And would hate for the video to slow anything down as I will have many drives and interfaces on the TB ports that need the data.
I am not looking to mirror the displays, but want “Extended Desktop”. I am hoping the 1 HDMI port can support that somehow, maybe with adapters ?
Any input would be greatly appreciated as far as my options.
Thanks !

  • ITunes breaks Airplay extend desktop via Apple TV

    Hi there, using my MPBr 15in with Yosemite installed and an Apple TV.
    I have been watching photoshop tutorials in an iTunes playlist via extended desktop (Video played on extended desktop on TV, I'm following along with Photoshop on my mac).
    I had put my mac on charge and did some things for a while, came back and went to continue my tutorials. But for some unknown reason when I select play in iTunes, instead of just playing on the extended desktop like it was earlier, iTunes quits the extended mode, 'sends' the video to the Apple TV which is a bit of a bumpier process then I'd like. Not to mention it needs to 'buffer' the video each time the next one is played. The worst issue is that the video is zoomed in too far, meaning I cannot see the photoshop tools or the menus along the top and no way to change it (it seems at least). I could forgo the Airplay streaming if it didn't have that issue.
    No Apple account is signed in to the Apple TV.
    I have tried changing a couple settings in Apple TV (including overscan settings on/off) to no avail. Also changed iTunes setting of Airplay that appears next to the volume slider. No matter what I try when I play the video, extended desktop mode turns off and iTunes streams just the video to Apple TV, also meaning I have to completely disconnect from Apple TV and reconnect again.
    So my question is, how do I force iTunes to not use Airplay streaming when I have specifically configured the computer to extend the desktop? I want to extend the desktop!! Using the multiple desktop feature is useful!
    Why does it assume I want to stream it independently rather than keep the second desktop?
    Why has it done it now, instead of before? I never pressed anything that I know of. It just decided to do it.
    If for whatever reason there is no way to turn this auto configuration off, how do I stream the video so it does not cut off the edges?
    Thanks in advance. If I figure it out I'll be sure to post what I found here.

    Troubleshoot the network, starting with power cycling the ATV and router.

  • G4 Extended Desktop via 'dual display'

    My G4 has two outputs from the Nvidia Card, a standard vga and the
    'rounded edge' style AppleDisplay output. Two part question here:
    1) may I simply use an appledisplay connector-to-vga converter dongle,
    in order to send through that second output to a standard vga (non apple)
    monitor?
    2) Would using these outputs simultaniously render the 'extended desktop',
    or are they just a duplicate of the same output?
    Thank you kindly for any info on this.

    It depends on which NVIDIA card you have. Anything older then the GeForce4 MX won't run two VGA displays. The GeForce2 MX TwinView can run two displays, but the ADC to VGA adapter won't work with this card, so only one can be VGA.
    If your card does support dual displays, you can choose mirrored or extended desktop in the "Arrangement" tab of "Displays" system preference.

  • Extended desktop = slow startup

    Hi, Im using IMac mid 2011, extended desktop via VGA converter (Apple product).
    About an years ago (Maybe it was a time when I started use extended desktop via VGA converter), my IMac starting to slowdown on startup, here is the symptom s:
    1. Click the Power button.
    2. Startup choir. (Boeeiiiing!)
    3. No screen reaction. (Black screen)
    4. 30sec of wait. (Sometimes, 5min)
    5. Screen on. (White with Apple logo)
    6. Oh god Finally!
    I thought this was caused by bootcamp till now, but now I think it was a simply caused by this VGA converter.
    Before I push a power button, I removed this VGA converter. Then the screen immediately turn on (going white with the apple logo) with startup choir (Boeeeiiiing). Then again startup with VGA converter connected, the symptom I mentioned above starts again.
    Is there any solution for a fast startup rather than disconnect the VGA converter everytime before turn on IMac?

    Reset the SMC and PRAM 2-3 times back to back. Then re-start normally and test. If that does not help then try a different connection such as HDMI, it's possible the connection and/or cables are going bad to the VGA connection.

  • Is it possible to airplay my extended desktop to multiple apple tv at the same time

    Hi
    I am looking to do video distribution in the venue I work in thrue multiple apple tv. The Idea is to use AirPlay and to send my extended desktop to about a dozen apple tv at the same time. is it possible to do it ???

    Winston is correct you may want to consider a multiplexer its what places like bars restaruants usse when the wat several tvs to use the same imput. is cheaper then several apple tvs hers one at $132.74 i have never used it but searced google and found it would give you up to 8 tvs of one HDMI signal.

  • I cannot get my iMac to connect to my macbook via Thunderbolt to use my laptop as an extended desktop

    I am trying to connect my iMac 21.5" desktop to my macbook pro via Thunderbolt cable so that I can use my laptop as an extended desktop. I have tried using detect displays to get it to show up and nothing happens. I've tried doing command + F2 to make it a targeted display, but the only thing I can get to happen is my iMac will mirror my Macbook and that's not what I want. No matter what I have tried it hasn't worked. I have tried turning both computers off and I have a brand new thunderbolt cable. I've updated all the software. Is there anything else I'm missing??
    I'm running OSX Yosemite 10.10.1
    Thank you !

    We've already done all of that. And we used the same thunderbolt cable to connect two iMac's and that worked totally fine doing the Command+ F2. I don't understand why we can't get the macbook to do the same.

  • Is it possible to assign an extended desktop to be an external desktop for a window's machine?

    I have an iMac with Lion and a Windows Vists Laptop and corresponding external monitor on my desk. I'd ideally like to use my iMac as an external monitor for the Window's machine and essentially remove the physical one from my desk.  Make sense?
    I already have 4 extended desktops created on my iMac and I'm HOPING that I could assign Desktop 4 (example) as the external monitor to be controlled by the Vista machine. I'd like to be able to flip between my Mac OS and the "extrernal monitor'' via the 2-finger-swipe gesture. Anyone have any ideas?
    NOTE: I also have Paralles installed with Windows 7 running on my iMac, but I specifically need the Vista machine to have the external monitor, so please do not suggest this solution.

    Thank you!  While reading these directions, I realized that I have the wrong connector.  I have the old Mac Monitor serial port to VGA instead of the MiniDisplay port to VGA needed (didn't even think about this computer not having that port available).  I just bought the correct one from Apple, so I'll attempt these instructions as soon as it arrives.
    To confirm: I'll be able to run the iMac as the external display and have Lion open simultaneously, right? (Obviously not both on the screen simultaneously, but the ability to "switch" views) Based on the article, the trick is turning the Target Display on/off with the Command + F2 buttons (as opposed to assigning an extended desktop and using gestures), correct?
    Again, thank you for your help!

    How are you running this program? Is there a top level vi which calls the ones you posted? The Display image on screen.vi will display two images in succession, but according to the note on the block diagram the second image is blank. It seems as though this would intentionally create a flicker.
    The sequence structure is unnecessary. Dataflow will determine the order of execution. The only exception is the time delay in the third frame. Since it has no data dependency, a single frame sequence may be useful to assure that the delay occurs before the picture is updated. A simple state machine might be a more versatile architecture for what you may be trying to do.
    It is not necessary to write the FR.PanelBounds property immediately after reading it, nor is it necessary to read it a second time in the second frame. Just wire from the first read.

  • External Monitor - Mirror Only ... OR is Extended Desktop possible ?

    If I connect a monitor to my new Intel iMac must it mirror the built-in monitor or can it be set to extend the Desktop ??
    I have seen a bit of software called Desktop Spanning or something like that to make extending the desktop accross a second monitor connected to an earlier type of iMac. Will that work or is that necessary with the new iMcs ???

    All the intel macs support extended desktop, no hack needed.

  • Setting Up Extended Desktop

    I am trying to set up an extended desktop for my iMac.  The operating system on it is 10.6.8 and I am trying to set it up so that the extended desktop utilizes my Macbook Pro system 10.7.5.  I have the thunderbolt cable and have connected it to both computers and tried the following:
    System Preferences -> Displays -> Arrangement
    However, when I go into system preferences there is no option under displays for arrangement.  What am I doing wrong or what should I be doing to make this work?  Is it even possible?  Thank you.

    There is no MacBookPro model that I know of that you could use as an extended desktop for your iMac.  I don't think any MBP's ever supported use of the MBP as a display for another computer.
    Only certain iMac models support(ed) their use as a monitor for another computer connected to it via miniDP.  If you have such an iMac, you may be able to use it as an extended desktop for your MacBookPro, but not the other way around.

  • Dual Monitor (Extended Desktop) Information Requested

    Hello,
    I am gathering information regarding the addition of an additional monitor to serve as an extended desktop for my iMac 2GHz Intel Core Duo (purchased in early 2006).
    Questions:
    1) Is it possible for this 2 1/2 year iMac to have an additional monitor?
    2) My iMac has a Mini-DVI port on the back. While looking at other monitors, I have been seeing 15 pin High-Density D-shell (VGA), Video - 24 pin DVI-D, and Video - HDMI interface inputs
    3) Which one of those interface types is recommended?
    4) Does Apple require a proprietary cable to connect with the above mentioned monitor?
    Thank you for any information!
    Tony
    3)

    Yes it is possible to have an additional monitor. I would compare the 20" iMac display to DVI quality although I believe HDMI is the highest quality (probably comparable to the 24" iMac displays). You will need a mini-DVI adapter to connect any display (see link below). I would recommend a DVI connection using a monitor the same size as your iMac that can handle the same resolution as your iMac display. If unsure what this resolution is go to system preferences>displays.

    You can also read some of the reviews from this mini-DVI adapter as most of them are trying to do what you are doing. You will also need a standard DVI cable (sometimes included with monitor) to connect to the new monitor to this adapter. There is also a mini-DVI to VGA adapter - although I wouldn't recommend this connection because it will be lower quality than your regular display. And a cable that connects DVI to HDMI if you decide to go that route.

  • Front Row with Extended Desktop

    Im interested in purchasing a new Macbook and using it along side my plasma. Is it possible to run Front Row from the macbook using its screen for the interface and displaying the content on the plasma via the extended desktop?

    Currently Front Row only displays its menus and video content on the primary display. Any other displays are blacked out while Front Row is activated.

  • Does Portg R700-17W lsupport extended desktop across 3 screens?

    Hi,
    I've a Portg R700-17W laptop with a replicator port. I'd like to have an extended desktop in Windows 7, with one external monitor on the VGA port, one on the HDMI, and the laptop screen. Is this possible? If so, what resolutions can it support?
    Many thanks in advance for your help.

    Dont think its possible using an port replicator you will need to use something like Dynadock U3 since the Dynadock supports an own graphic chip and it allows you to use tree displays (2 external and 1 internal)
