23" Apple Cinema Display & 15" MacBook Pro?

1) Any ideas on how to crank up the res on a MacBook Pro for external mirroring?
A manager at my company ordered a 15" MacBook Pro & a 23" Apple Cinema Display for the purpose of Mirroring.
When spanning, the laptop and the display look great (and both run in their native modes of 1920 x 1200 and 1440 by 900, respectively), but when mirroring is enabled, the MacBook video card acts like it can't power the 23" LCD properly. It wants to default both the 15" built-in display and the Cinema display at 1440 by 900 - which is unacceptable.
2) Is it possible to close a MacBook Pro's lid and continue to power the external monitor without the MacBook sleeping?
3) Is it possible to toggle the MacBook Pro's video signal to turn OFF the built-in laptop display and ONLY run on the external display? I remember older PowerBooks being able to do this. Many PC laptops will allow you to disable the local video and only send a signal to the external display (for presentations etc).

1) Any ideas on how to crank up the res on a MacBook Pro for external mirroring?
Mirroring is pixel to pixel. The MacBook only has 1440 by 900, so that's all it can show on the external display when mirroring.
2) Is it possible to close a MacBook Pro's lid and continue to power the external monitor without the MacBook sleeping?
Attach the power adapter and an external keyboard and mouse (bluetooth is OK if it's set to wake the computer). When you close the lid, the computer will sleep, but will wake (and continue to run with the lid closed) when you use the external mouse or keyboard.
3) Is it possible to toggle the MacBook Pro's video signal to turn OFF the built-in laptop display and ONLY run on the external display?
Not with the lid open, but if not mirrored, you can move the menu bar to the external display by following the instructions in the "Arrangement" tab of "Displays" system preference.

  • I have a 25" Apple Cinema Display and Macbook Pro. Want to use iSight camera on ACD.

    When I use Skype or Google+ Hangout, I'm not able to use the built-in camera on the ACD. Is there a preference to switch camera from Macbook Pro to ACD?

    I don't know about Google+ but in Skype's Preferences, there's an Audio/Video tab and within that window there's a popup menu for the camera.  Does that allow you to select the ACD?

  • Cinema Display and MacBook Pro - Power Button won't work

    I have been using a 20" Apple Cinema Display (plastic model) with a 17" Powerbook and never had a problem. Recently I acquired a 15" MacBook Pro and it's like the power button on the display has no use at all. The only way to turn on the computer is opening the computer lid, turning it on and then closing it. The display also won't shutdown the computer, although the power button light reacts to the touch. The funny thing is that the display settings button work fine. Does anyone has a clue?

    Malcolm, thank you for the answer! But I still don't understand why my new MacBook Pro, having exactly the same connector as my older Powerbook had, won't behave the same way? I'm still using the same DVI to ADC adapter, I'm wondering if the new Macbooks maybe have some PIN assignment disabled on its DVI connector. And anyway, shouldn't the power button be able to at least shut down the computer, as long as pressing it would just open the shut down dialog box?

  • Compatibility of Past-Years Cinema Display with Macbook Pro Late 2011, and other displays.

    Hello.
    I'm inquiring about the compatibility of Apple cinema displays from years past with Macbook Pro 15" Late 2011.
    For instance, will all Apple Cinema Displays from, say, 2008 onwards work with my mbook?
    They can be had fairly cheaply on the used market.
    What is the earliest model that will be compatible?
    I've never had an external monitor for my lappies, so I am very clueless. I know DVI is a common connection, but there is no DVI port on my lappie.
    I would also be very curious as to what would be suitable displays from other manufacturers, particularly Samsung and Dell.
    The size doesn't have to be big, 20-23 inch is fine, I am more worried about good resolution [no obvious pixellation]
    If a screen is big, but has good resolution that's even better of course, but I'm not ****-bent on a big thing.
    The mbook 15" screen is just a bit squashy for home use really.
    Thank you very much in advance for any advice.
    Feel free to link me to other threads as an answer, I have done a bit of searching around, but still confused.

    I have the same MBP and recently bought a 23" cinema display on Craigslist for $140.  It works great.  I had a display port to DVI adapter and it worked fine.  Built a stand to hold the laptop vertically so it's out of the way.  Don't know about older displays but anything with DVI should work fine.
    The screen size and resolution are great for photo editing.  I now have the best of both worlds, a display that rivals my wife's iMac and portability.

  • 27" Cinema Display & 17" Macbook Pro not calibrating correctly

    I've had my 17" macbook pro hooked up to a 27" viewsonic LCD monitor for about a year.  The colors have never been right, as many times that I tried calabrating them through the built in Apple calabration system, or if I use my X-rite I1Disply 2.  Today, I bit the bullet and bought the 27" Apple Cinema Display and nothing changed, the colors are still off.  The monitor looks slightly warmer than the laptop. I'm a wedding photographer, so it can be frustrating not being able to use the bigger monitor to edit.  Thanks in advance for you help...

    Would changing the contrast help?  I don't know, I'm just asking, because there is a contrast control in the Universal Access preferences Seeing tab.

  • Apple Cinema Displays & 2007 MacBooks

    hello. which apple cinema displays are compatible with older (2007) white macbooks, in terms of connectivity, adapters, etc...?

    Any Apple LCD will work except for the 24" LED or 30". You will need a Mini-DVI to DVI adapter.
    <http://store.apple.com/us/product/M9321G/B?fnode=MTY1NDA5OQ&mco=MjE0NTg3Nw>
    The 20" is the only one currently sold at the Apple online store, but some stores may still have some 23" models in stock. 15", 17", and 22" models may be available used. If they use ADC, you will also need a DVI to ADC adapter

  • How to connect multiple Apple LED Cinema Displays to MacBook Pro

    I have an Apple 24 inch LED Cinema display that I run from my MB Pro. I mainly use the MB Pro+ screen for document editing.
    I would like to run a second Apple 24 inch Cinema display from the MB Pro. I am presently running another monitor successfully via a Dynalink USB splitter but would really prefer to run a second Apple monitor. I have enquired at two Apple Stores and browsed lots of sites. Multiple monitors from MB Pro seems ok (as long as it's not two Apple monitors). I would be surprised if Apple is content to pass up the opportunity to sell more of these superb screens.
    Grateful for any advice and suggestions

  • Installation of 27" cinema display with macbook pro silver key and bootcamp

    For everyone out there who may be interested in using the new 27" cinema display with an older Macbook Pro Intel with silver keys and bootcamp.
    What is needed:
    1. Apple 27" cinema display.
    2. Macbook pro Intel silver key model
    3. Altona Dual Link DVI to Mini DisplayPort Converter (Model AT-DP400)
    4. Bootcamp 3.1 drivers from Mac OSX Snow Leopard V10.6.3(retail)
    Procedure:
    1. Update your display software on the Mac OS side. Apple has posted an update on their software downloads page, "LED Cinema Display Software Update 1.0" After doing so, make sure that the 27" CinDisp is operating correctly and you can change the brightness from the system settings.
    2. On the Windows side, install the bootcamp 3.1 drivers. These are on the Snow Leopard distribution CD. However, there is a bug in the .msi installer that causes the installation to go into an endless loop. This must be resolved during the installation of the drivers. The following article discribes how to do this:
    http://discussions.apple.com/thread.jspa?threadID=2305631&tstart=0
    3. After you have successfully installed the bootcamp 3.1 drivers, then install Apple's bootcamp update: "Apple Magic Trackpad and 27-inch LED Cinema Display Update for Windows 32 bit".
    Good luck, it works!

  • How do i connect a cinema display to macbook pro

    I got a hand-me-down cinema display from my work for hookup to my macbook pro - there are 4 different connections attached and I don't know what goes where.

    You can connect to a Thunderbolt port with

    or the HDMI port with
    <http://www.startech.com/Cables/Audio-Video/Video-Adapter/HDMI-to-DVI-D-Video-Cab le-Adapter-M-F~HDMIDVIMF>
    If the display uses ADC (Apple Display Connector)
    <http://upload.wikimedia.org/wikipedia/commons/0/09/AppleDisplayConnector.jpg>
    you will also need a DVI to ADC adapter.

  • Connecting a 20" Cinema Display and MacBook Pro 4,1

    I admit I bought a cinema display from a co-worker because I thought it'd be nice to have a larger screen to attach to my MacBook pro 4,1. However, the monitor has a flat connector that doesn't seem to fit anywhere on my laptop. Is there some sort of adapter I can get? I've seen similar questions posted, but none with my exact specs.
    Or, should I just sell the monitor back to him or someone else?

    It says: Model Name: MacBook Pro
    Model Identifier: MacBookPro4,1
    Processor Name: Intel Core 2 Duo
    Maybe I'm a total dork. on the right side, I see, back to front: a monitor adaptor (which i use at work to plug in a Dell), an Ethernet port, a square-ish port with a firewire symbol, another firewire (with the 'dog-eared' edge), a USB, and then a tiny tiny rounded little hole that doesn't appear to go to anything. On the other side, I have the magnetic power cord, another USB, and two small round holes - one for DVI?, one for headphones.
    This is where I get a little confused. The Cinema Display looks like the one in the bottom right of this page: http://en.wikipedia.org/wiki/Mini_DisplayPort, and the little round port on the left of my laptop has the same symbol, but is the size of the headphone port.
    Do I need some adapter from the squareish one to the little round one?

  • Dual Display - help with Cinema Display for MacBook Pro where MB won't detect displays.

    I just got a Cinema Display (a1081 20") ("CD") off eBay to use as a dual screen with my Macbook Pro OS X 10.6.8 ("MB"). However, I can't get MB to recognize CD! I've tried power cycling both the MB and the CD with and without USB cord connected. MB won't recognize CD display in any situation. However, it is recognized in some capacity although I can't use dual display because the CD power button triggers MB to ask me if I want to restart, shutdown, or cancel.
    Any help is appreciated!!

    Have you tried smc and pram resets?
    Try Detect Displays in the Displays preference pane.
    Does the Displays preference pane Arrangement show two screens?  If so do click gather windows and check the resolution setting of the new screen.

  • 5770 with 27" Apple LED and two 20" Apple Cinema Displays w/Mac Pro

    As stated, I just bought a brand new Mac Pro 8-core (2010 ID 5,1) with a 5770 card and I'm trying to hook up a new 27" Apple LED and two 20" cinema displays. One of the 20" monitors is using the MDP adapter into the 5770 and the 27" is directly connected to the other MDP port. When I try to hook up the other 20" to the DVI port on the 5770 I get nothing. The screen is black and the it is not recognized as being connected. I'm using the standard DVI connector that came with the 20" direct into the 5770. To make sure it isn't a monitor problem, I switched out the 20" displays and both work using the MDP adapter but neither work plugging directly into the DVI port on the 5770. I believe the 20" monitors use DVI-D. (Is that correct?) So what's the scoop on getting blank screens when plugging into the DVI port on the 5770? Thanks for any help.

    "• the 27" is directly connected to the other MDP port.
    • One of the 20" monitors is using the MDP adapter into the 5770.
    • When I try to hook up the other 20" to the DVI port on the 5770 I get nothing.
    Note: If you are using an Apple Mini DisplayPort to DVI adapter, only two displays are supported across the three ports.
    If you are connecting three displays, any DVI displays must be connected to either the Dual-Link DVI port or must use an Apple Mini DisplayPort to Dual-Link Adapter.
    You MUST use All "Active" or "Powered" Mini DisplayPort connector such as the Apple Dual Link, or you can only use two displays

  • Dual 24" Cinema Displays on MacBook Pro

    Hi Everyone,
    I am interested in getting two 24" Apple displays on my MacBook pro (one-week old). Apple tells me that this is not possible without a dual-display head, would that be the Matrox P690 Plus LP PCIe x16?
    If it is, do I replace the MacBook pro video card with this video card, then what do I do?
    Thank you to anyone who responds, I greatly appreciate it.

    If it is, do I replace the MacBook pro video card with this video card, then what do I do?
    Keep in mind that the MBP does not have a discreet, removable video card. All the video hardware is soldered to the logic board. Sounds like the Apple tech was thinking "Mac Pro", a desktop machine that has a video card slot to allow card upgrades.
