Original Cinema Display as Second Monitor

Hi All,
Is it possible to use my Cinema Display - not the new one, nor the Studio Display - as a second/external monitor for my iMac 21.5in? If so, what cable would I need?
Thanks,
Jon

If you mean those older Cinema Displays with the Apple Display Connector (ADC), then you need a mini-DisplayPort to DVI adapter and the DVI to ADC convertor sold by Apple or others (expensive). I bought Apple's DVI to ADC box last year and use it to add the 23" Cinema Display HD to a Powerbook G4. Works great.
I haven't bought a mini-DisplayPort to DVI adapter/cable to use the ADC display off my iMac, because I don't have the desk space for two large monitors and two large printers.

  • IMac 24 and 27 Cinema Display as second monitor

    Got older 24 iMac with mini DVI output for external monitor (ATI Radeon HD 2600 Pro 256 MB graphics)
    Bought 27 Cinema display to use as 2nd monitor.
    Bought Atlona DP400 to convert signal.
    Connected everything and only resolution I get on 27 Cinema display is 1280 x 720, which is frustrating.
    Is there any way to set higher resolution for external monitor? Scaled shows only 800 x 600 and 1280 x 720 (as best for display)
    Thank you for help!

  • How can I run a 27" Apple Cinema Display and another monitor from my MacBook Pro?

    Hi everyone,
    I recently purchased a brand new 15"  MacBook Pro to replace my old one. I was told when ordering it that I would be able to hook up two external monitors to it using the Matrox DualHead2Go hardware. So, I also bought a 27" Cinema Display (non-Thunderbolt since it wouldn't work with the DH2Go). However, when I contacted Matrox they said their products don't support screens as large as the 27" ACD.
    Bummer!
    So, my question is: does anyone know how I can hookup a 27" Apple Cinema Display at 2560x1440 and a Acer 22" monitor at 1685x1050 (or, anything less really) to my new MacBook Pro?
    I've looked around and haven't been able to find a good answer.
    Thanks for your help!

    Will something like this work? A USB to VGA adapter? Can I use this at the same time that I have a Cinema Display plugged into the Mini-DVI port and will they both work at the same time? Anyone know?

  • 20" Cinema display as 2nd monitor??

    Will the 20" Apple Cinema display make a good 2nd monitor for my 20" (non-AL) iMac?

    It should work perfectly. All you need is the miniDVI-to-DVI adapter and a DVI-D cable.

  • Extending display with second monitor

    I am trying to add a second monitor to expand my desktop area. I routinely do this with my G5 laptop by simply plugging in a second monitor, clicking on DISPLAY in SYSTEM PREFS, clicking ARRANGEMENT, and clicking off MIRROR DISPLAYS.
    With the iMAC G5 ARRANGEMENT does not appear as an option and default seems to be mirror. Any way to make this work?

    This is an update to my previous post. I searched on Google about this problem and found an answer -- an old Macworld article:
    http://www.macworld.com/article/39969/2004/10/imacscreenspanning.html
    It describes a freeware program called Screen Spanning Doctor. I printed out the page and followed the instructions. It worked! I now have a Samsung SyncMaster 930B set at 1280 x 1024 and my iMac G5 set at 1440 x 900 (maximums for both) and They are not mirrored; the Samsung monitor extends the desktop of my iMac G5. I couldn't be happier.
    Just in case Screen Spanning Doctor does not work for you, be sure to print out this Apple support document, Resetting your Mac's PRAM and NVRAM:
    http://support.apple.com/kb/HT1379?viewlocale=en_US
    You can never be too careful. I believe what this will do is undo whatever changes Screen Spanning Doctor does. Per the Readme:
    "This program is intended to unlock some features of the graphics hardware in some Macs (iBook, iMac, eMac but not for all models - you can find a complete list at my website http://macparts.de/ibook). On supported Macs it will allow the use of an extended desktop where usually only mirrored mode is available. This enables you to use an external display to extend your workspace. It will also unlock additional resolutions for the external display making it possible to driver high-resolution screens. This is especially nice if you want to use an LCD panel that has a higher native resolution than the 1024*768 of the internal display. After you apply the patch you should see an additional tab in the displays prYou will only see this tab if you have at least the monitor adapter plugged in."
    Good luck! (I'm going to make a donation to macparts.de, which created this program. I figure it's worth $19 -- what I paid for the VGA display adapter at the Apple Store.

  • 30" Cinema Display as External Monitor for 15" iMac?

    Is there any way to hook up a 30" Cinema Display to a flat-panel "lampshade" iMac? There is no DVI input on the iMac.

    No. There is a VGA output, and (expensive) VGA to DVI converters, but they won't work with a 30" display.

  • An iMac 20" with an 20" Cinema Display as second screen in dual

    I'm planning to buy an iMac 20" but I want to be sure of something before. I want to know if the screen of an iMac 20" and an 20" Cinema Display put together will be exactly at the same position. I search a lot online to have a picture of this but I only found some 17" iMac put together of an 20" Cinema Display. If someone can answer and/or give me a picture of this that would be really nice.

    Here is a quote from the user reviews section of Amazon.com, about the new 20 inch Imac core duo:
    Video out - The new iMac, for the first time ever, features a Mini-DVI output. This allows, with adapters, the ability to connect the iMac to a DVI display, a television via composite or S-video, or an analog display via VGA. I have my new iMac Core Duo connected to my 20-inch Apple Cinema Display, and it works perfect! A nice feature. This allows for screen-spanning, so I can take advantage of both screens.

  • DVI connection to second monitor doesn't work

    When I had the connection from my Mac Pro to my two monitors (20" Cinema display and 19" Princeton monitor), I had the black screens for a few seconds for both monitors then return to normal. It happens anytime. I read the forum and changed the VGA cable to connect the 19" Princeton monitor and now both monitors work fine.
    Do I have to live with the VGA cable option or anyone know how to utilize the DVI connection capability of Mac Pro please help?

    I tried to locate the right slot (x16) by going to
    Expansion Slot Utility and changed from #1 to #2. It
    showed my configuration of the PCI card now is x16 or

    The problem is still the same with DVI connection to

    appreciated.

    I'm fresh out of idea's. I assume that your card is a 7300GT, correct? I had an out of the box failure with mine and Apple replaced it. I was lead to believe that there were quite a few failures with the card. Interesting, they didn't even want the old one back.
    I'd go the Applecare route next and see what they say. FYI, I have two of these running three monitors (all apple flat panels) all on DVI connectors.

  • 32" Cinema Display compatible?

    I'm planning on upgrading from my MBP (original) to a new one. I use the 32" cinema display as my monitor. Will I still be able to connect this display to the newer lines of Apple laptops? Thanks in advance.

    Okay, then post in the white MacBook forums, here:

  • 10.5.2 Update - Second monitor "blinks" after wake from sleep

    Posting in the off chance that others have seen this behavior. This seems to be Leopard related, and did not start happening until after I installed the 10.5.2 update.
    After waking from sleep my second monitor will blink on and off for anywhere from 2 seconds to about 30 seconds at which time it functions properly. It does not do this on initial startup OR when booting from my tiger volume (backed up with superDuper before a clean install of Leopard). Unplugging the display and plugging it back in also stops the "blinking"; turning the monitor off and then on has no effect.
    My machine is a early (2007) model 2x2.66 dual-core with 3GB of (Apple) RAM and a GeForce 7300 GT. All firmware updates have been applied and software update reports no updates available.
    The displays are both Sceptre X9G-NagaV 19" flat-panels connected via DVI, though I see the same behavior when using my 20" apple cinema display as second head. (I know these are cheap monitors. Please refrain from telling me that the displays are at fault - it 's not a problem with the display, as this doesn't happen under Tiger. The monitors have performed admirably for over two years)

    Have you tried unplugging the second monitor, rebooting and letting it run without it for a little while, and then plugging it back in to see if it clears some persistent loading problem? My monitor has always gone out on me kinda randomly, but I think it's my GPU in my PMG5 that's losing power and resetting or something so it wouldnt be the same issue (I've gone through two so far with the same results).
    Alternatively, try changing some of the display settings, such as resolution, color, and such to see if the change corrects how it's loading the display.

  • PC Gamer Looking To Get 23" Cinema Display

    I'm a hardcore PC gamer, that built a Nvidia SLI box for just gaming and nothing else.
    Finding a awesome high-end 24" sized LCD for 1900X1200 gaming is not a easy task.
    So this road as led me to Apple, a lot of people in the PC world are saying the 23" Cinema Display are nice monitors for high end gaming.
    Can someone back this up, that also lives in the PC world, and might know someone that uses this for SLI as well?
    THANKS

    I don't care for the Dell LCDs even though they are the big rave right now, because for the average consumer they are a tough price to size to beat.
    Average I'm not, I'm looking for the best, why I said SLI, is for playing with it the way it's meant, that's bigger screens and higher resolutions, yes I know SLI doesn't effect the monitor, by what I think you are saying.
    Actually hardware on both sides, when you have something like my box, is to compliment each other, bring out the best, so in that statement SLI has a effect and vice versa, but anyways....
    With my rig specs I didn't skimp and a LCD is the last thing I plan on skimping on too, so a great one is all I want and I'll pay for it too, but 24" is big enough, anything beyond that is going to be poor performance and a waste.
    These are my box specs needing something worthy to support it:
    AMD X2 3800
    Abit KN8 SLI

  • 20 Inch Cinema Display Went Black

    i just rebooted my mac mini that is connected to a 20 inch Cinema Display and the monitor never came back to life. The screen is totally black and the firewire, USB and video cables are plugged into the computer fine. When I look at the computer on Remote Desktop from my laptop i can see that the mac mini is fine. i can also see that when i hit the on/off button on the display that it prompts the shutdown/restart popup on the mac mini so it is communicating with the mac mini. i have also plugged the display into my PB and again I get the shutdown popup when i hit the display's on/off button. is there anything to do to bring it back to life or is it dead? its not even a year old.

    Hey,
    Same problem happening here, You described it exactly. Even the magenta box. Mine also happens most in the open windows, not when the desktop. I am trying to figure out when exactly it is happening. The third item I have issues with is that blocks of data are 'stuck' in a genie expansion like motion so it is blurred and dot displaying in that 3x3 inch square section. Could have something to do with refreshing? Sometimes I notice the window will fix if I manually resize the window.
    Hope this helps any one who is trying to help us out.

  • Calibrating MacBook Battery w/ 23" Cinema Display

    I am trying to calibrate the battery as described in the manual:

    This is essentially the same procedure as for the PowerBooks:
    http://docs.info.apple.com/article.html?artnum=86284
    I'm using a 23" Cinema display as my monitor and run the MacBook with the screen closed so the external display is my only display.
    Here's my problem....
    when I disconnect the POWER from my MacBook, the external monitor goes blank/dark. I have tried opening its screen, and the external monitor flashes on, but does NOT project the screen image.
    So, my question is...
    Is there some limitation on using an external monitor with a MacBook running on battery?
    Thanks for your help.

    Yes, you MUST be on A/C power when using an external display. There's no way around that.

  • How to connect my Cinema Display as a second monitor

    I just purchased a new 27-inch iMac, and I explained to the Apple folks that I had a 17-inch cinema display (silver clad model) that I wanted to connect, for a dual monitor set up. They told me just to get the Mini DisplayPort to DVI Adapter, but I was surprised to realize that's not going to work.
    Can anyone tell me how to do this, and what connector is actually needed? I have the big old white power brick that I bought to daisy chain my old 17 and 23 inch displays with my old configuration (Mac Pro).
    Or can you not have a second monitor with an iMac?

  • What do i need to connect my 30" cinema display as a second monitor to my new 27" imac?

    I recently purchased a new iMac and want to run my 30" cinema display as a second monitor. My local mac experts told me to use a mini display to dvi adaptor, but that didn't work for any of my cinema displays - the 30" that i want to use and a 21" that I have. I called the guys back up and after a little research, he told me to get a mini display port to dual link dvi adapter. This costs $99, so I want to be sure it's going to work.
    Does anyone know if this will work, or if there is a better idea, or ****, does the new iMac even except a 2nd monitor.
    Thanks. Looking forward to your input.

    Well I may have heard wrong, but I do not believe that you can hook that 6 year old monitor to the latest 27" iMacs with ThunderBolt. I would do more research before putting out the bucks, or make sure that you can return it if it does not work.
    But do let us know if you try it and it works.
