2 External Monitors from Thunderbolt

Is there a way for me to drive 2 external DVI displays from the combo Thunderbolt/MiniDisplay Port on the 2011 MBP's? As nice as Apple's Thunderbolt Cinema displays are, they are a bit out of my price range.

  • HT2494 Reboot my Macbook Pro when using external monitor w Thunderbolt to VGA adapter

    I have a Macbook Pro running 10.9.2 OS X (MacBookPro8,1). I never had any problem w that but yesterday i bought an external monitor (kind of old model from LG - L1900E). Well, i was trying to extend my Macbook Pro display through a Thunderbolt to VGA adapter. It worked at first but it started rebooting my Mac. I just disconnected that and the reboot stopped.
    It sounds to me like a Software related BUG regarding connection or something strange.....
    I would like to have some help on how to proceed w that ? Is there a specific SW i need to install to use that ?
    I am kind of disapointed because i heard that one of the major items the new OS X was about external displays.....
    Looking forward a help from an apple specialist, Tks !

  • How to display 2560x1080 on external monitor from MBP or MBA?

    Is there any way to make MBP 17 (Intel HD and nVidia GT graphics, SnowLeo) or MBA 13 (Mountain Lion) display 2560x1080 on external monitor (LG 29" ultrawide)? My MacPro with RadeonX1900 card (10.5.8) does it perfectly but I cannot find a way to get the laptops to do it. Tried res. switching apps, still no good. Thanks.

    It worked perfect for me. Maybe settings should be different for your laptops. In my case I'm using a MBP 15" with a GeForce 330M.
    The monitor I have is the LG 29EA93 (21:9) @ 2560 x 1080.
    Make sure you have exactly same values in Switch Res X. Special attention to "Scan rate".
    You can see in the capture below that it's working
    and, just in case, here you have the settings that worked for me
    It might be also different for each video card...
    Greetings!!

  • What is the max resolution for external monitors from the intel hd 4000 graphics driver

    What is the max resolution supported by the intel hd 4000 graphics driver found on the 13in MacBook Pro for EXTERNAL monitors?

    OK so after doing much research... this seems to be the best workflow.
    Bring HDV in to FCP as ProRes 422.
    Edit show... add bells and whistles, etc.
    Export movie as ProRes 422.
    Then for the client - ensure that they have latest version of Quicktime and download the Apple ProRes Quicktime Decoder (for mac or Windows). (It is assumed they have a decent computer to play back on.)
    The client will then be able to play a movie encoded as proRes 422 and all will be happy.
    As a back up a high resolution h264 file can't hurt.
    Thanks for everyones input. We got there in the end.

  • I want to use multiple iPads as external monitors from a PC using the iPad VGA adapter (wired)

    I want to send a VGA signal to a couple of iPads using them as monitors. I currently use a pair of regular 13" VGA 1024x768 lcd monitors looping thru an LCD projector displaying the same signal sent to the projector.
    I want to use the iPad VGA adapter and WIRE them in just like a convention LCD monitor. Yes there are apps like air display and others but they don't allow cloning and have latency issues and must be networked. I need an app to use the VGA adapter and actually wire them in using a VGA signal from my existing VGA distrubution amp.
    The size of the iPad is perfect for my application however I cannot find an app to let me send a signal into the iPad via VGA adapter.
    Any ideas?
    thanks,

  • No 1920x1080 output to external monitor from MBP 2011 OSX 10.6.8

    Hi, I have a MBP 2011 running OSX 10.6.8.
    I have recently purchased an Asus ML249H Monitor and the Kanex Mini DisplayPort to HDMI Cable 10 ft (3 m) MDPHD10FT.
    The monitor should display at 1920x1080 natively but does not. The MBP max output resolution is 1600x900 on this screen. Is this a known issue with the MDPHD10FT cable or is it OSX? What it the work around to get 1920x1080.
    Thanks

    i had to go into iCal Preferences and delete my account and then put it back in.  Everything is working fine, now.

  • Calibrating external monitor from macbook pro

    Hello,
    I just bought a new Samsung t240 24" display for a late 08 macbook pro.
    Its connected from mini display to dvi.
    However the colors look really different from what they look on my macbook pro display.
    The samsung looks very sharp and bright, however there is a slight blueish cast, in contrast from the mbp display, which looks rather warmer.
    I already tried calibrating with the built in mac osx calibration, but it gives me the same result.
    Maybe somebody here has a calibrated profile for the t240 or a similar one I can try?
    Thanks and really appreciate any help.

    I know this is an old thread, but I just wanted to let people know there is another way of solving this problem without resorting to buying a DVI adapter:
    I've posted a solution here to a similar problem, it has worked for me and for others.

  • External monitor won't wake up

    I've just installed 10.5.8, and can no longer wake up my external monitor from sleep with the clamshell closed by pressing a key on my external keyboard, meaning that I now have to have the clamshell open (and macbook display active) when I want to use my external screen. I installed 10.5.8 specifically to solve the sleep issue that many users have been experiencing. Does anyone have any advice? Thanks.

    I have the new 15" Retina MacBook Pro connected to a Thunderbolt display using one of the TB ports. Earlier today, I discovered that I could connect a second older 24" Dell Monitor (2405FPW) I've been using for years by using the DisplayPort to DVI adapter I had on my old iMac, and plugging the Dell directly into the second Thunderbolt port on the MBP.  All was well, until the displays went to sleep (I have my laptop configured to not sleep for 3 hours, but have the displays sleep after about 15 minutes).  When I came back, moving the mouse and typing on the keyboard brought the Thunderbolt Display back to life, but the Dell monitor remained dark.  Pressing buttons on the Dell had the message "In Power Save Mode - press key on the keyboard" appear.  I tried turning the monitor off, back on, unplugging the DVI cable from the MBP, all sorts of things.  It just would not wake up.  When going to the System Preferences, the dell WAS recognized.  As I plugged and unplugged the DVI cable from the second TB port, the "Arrangement" tab would appear and go away.  So, it SEEMED like it was working.
    Final solution for me: I selected "Sleep" from the Apple menu to actually put the entire machine to sleep.  I then jiggled the mouse, and the machine woke up, along with BOTH monitors!
    So, it appears that if just the monitors go to sleep, the "wake" signal is not making it to the Dell.  If the ENTIRE MACHINE sleeps, they all wake together.
    Hope that helps someone.  I couldn't find an answer, so I found it trial-and-error.

  • 2012 iMac as external monitor

    Hi, got 2012 imac that I want to use as a external monitor from my PC with has displayport out.
    From research I see that to use it via HDMI or DVI you have to make sure you get an expensive bi-directional cable, but all the cables I can see are just called mini-displayport to displayport, where as I want to go from displayport to mini-displayport.
    Do I need to a different cable or are mini-displayport to displayport cables bi-directional?
    Cheers

    Hi, I don't think you can do it...

  • External monitor revolution only goes up to 1080p

    Hi everyone,
         I just get my new monitor Dell U2713hm today, but I am so disappointed that the resolution of the new monitor only goes up to 1080p. The font looks blurry, so I want to adjust it to higher resolution. I have tried to use Dual link + MDP, HDMI + MDP, and MDP to HDMI cable(CONNECT, by Belkin, and it's labelled "4k" on it box). Still, none of them works...
         It's so annoying for see blurry things on the screen, please help... Thank you so much!!!

  • Macbook Pro retina + Samsung LED 24" external monitor

    Hi all, I just bought Macbook Pro 13.3" Retina and im having some troubles.
    When I connect those two via VGA adapter I see some strange artifact effect on external monitor.
    I dont know hot to name that artifact but it is the same thing that you can see when you take your camera or smartphone and try to record old tv screen for example. You will see that parallel lines goes up or down. This effects is easy to notice when you put something with dark background on external monior (like Unity3D Pro IDE with dark skin in my case).
    The interesting things are:
    - when I switch external monitor from VGA adapter connection to HDMI-HDMI then everything works fine with no artifacts.
    - when I'm using VGA adapter and connect Macbook Pro to another external monitor (AOC 24" LCD) then everything works ok aswell.
    - when I take my Samsung LED monitor and connect it to another PC (Windows 8) with VGA everything works great.
    So I belive that this issue is related to all three of them (MacbookPro + Sasmung LED + VGA adapter) and I really dont know who to blame and what to do.
    Dose anyome have an idea how to solve this and what to do?]
    thanks

    Hi luisvf7,
    So it seems you are having issues with your MacBook Pro not displaying properly on your external display. It does sound like a frustrating situation. Let’s see if we can get you up and running.
    I would suggest that you use the steps in this article to troubleshoot the problem -

  • Connecting Mid 2012 MBPro to External Monitor

    I've recently purchased a Mini Display Port to Display Port cable to connect my Mid 2012 MacBook Pro (Non Retina) to a 23" Asus PA238Q IPS Monitor, when I connect it It displays an image ok, it sometimes flickers but the main problem is it won't display an image in any other resolution other than the MacBook Pros native resolution.
    The main reason I wanted to use an external monitor from time to time is for photography related work and using an IPS Monitor with a resolution of 1920x1080 would be hugely beneficial, not to mention the fact it's 23" not 15"
    Is there a way I can get my MBPro to display the image properly at 1920x1080?
    Huge thanks in advance for any help!

    Can you post a screen shot of your Displays preference pane -> http://support.apple.com/kb/PH4391?
    Should look something like this:

  • Trying to run 2 external monitors with HDMI splitter

    I'm trying to run two external monitors from my iMac using an HDMI splitter but I can only get signal to one. I've read a lot of forums saying it is not possible to run two monitors from an iMac but the two monitors can be mirrored, in fact, I would be prefer it if they were.
    I've got the mini-DVI to HDMI cable running to an HDMI splitter, one end going to my 52'' Sharp Aquos tv and the other to my 21" BenQ monitor in the kitchen.
    I would just like to be able to have both monitors playing the same video at the sametime, I don't understand why this would not be possible.
    I'm at work so I don't have the exact specifications but I recently purchased my iMac and have the i7 processor and the Radeon 5750 graphics card so I know it's not a hardware limitation
    What am I doing wrong?

    I will reply to my own question just because I figured out the answer.
    The Larger display has to be set to the maximum settings of the smaller display
    For example: My sharp aquos has to be set to 720p BEFORE plugging in the BenQ which will not do 1080p
    If you try to plug in the benQ before setting the Aquos to 720p, it will not work and you will not be able to change it after the fact.
    May seem simple now, but boy did that drive me crazy for a while.

    You can't, don't. The iMac can only be used as an external monitor from another Mac computer. Not from a Windows PC.
