20" Cinema Display with G4 dual 450

I just purchased a 20" Cinema Display to use on my G4 dual 450. I'm going to buy the ATI Radeon 7500 graphics card that's recommended, but I'm confused. Is there more than one version of this card? In the specs I don't see the Mac operating system mentioned.
My graphics needs are very simple so I want the least expensive card I can get that will handle the 20" display, and this one seems to be it. Also, is there anything else (adapter?) that I'll need?
Thanks,
Carole

Hi Carole,
The display you describe is a DVI display.
From where are you getting the graphics card?
If the ATI Radeon 7500 card you are looking at has no mention of Mac specifications, then it is probably not the Mac edition, more likely a PC edition.
Only Mac edition cards, or PC edition cards that have been "flashed" with a Mac ROM, will work in a Mac. As "flashing" is an after market modification, you are relying on the technical expertise of the "flasher" to give you a functional card.
The true Mac edition ATI Radeon 7500 is an OEM card (so is not generally available "off the shelf"):
http://www.ati.com/products/radeon7500/radeon7500me/specs.html
It has VGA and ADC output. You would have to get an ADC to DVI adaptor to be able to use the DVI display. Here's an example of an adaptor:

Given all the things I have just pointed out, it would probably be more appropriate for you to get the ATI Radeon 8500 Mac Edition (if you can find one, they are a bit rare). Howwever, it has DVI output, so you can hook the display straight in.
If you can't find the 8500, the next most available card would be the ATI Radeon 9000 Pro Mac Edition, but it has VGA and ADC output, so you would have to use the adaptor that I mentioned before.
Cheers!

  • Can I use a 30" Apple Cinema display with a new 27" iMac?

    I have a brand new iMac(27-inch, Late 2013), OS X Mountain Lion (10.8), i7 3.5 GHz, 32MB RAM, 4GB NVIDIA.  I will soon be upgrading it to Mavericks, if that makes a difference.  My understanding is that the resolution on it is 2560 x 1440.
    I'm looking at buying a used 30" Apple Cinema display.  I'd like to use it with my new iMac.  The only advantage for me would be that the 30" screen is larger and things on it easier to see (or so I'm guessing).
    I need to know if the 30" Cinema display would work with my new iMac, and if it would, as I'm guessing, give me a larger, easier-to-see screen.
    I currently have my new iMac connected to my old mid-2010 iMac as a target display (that old iMac has a minidisplay port--no Thunderbolt), and that works great.  I just want a larger screen.
    I called Apple support, and the tech rep wasn't sure it would work.  He seemed to think that the 30" Cinema displays were made with different connections.  Some had minidisplay ports (which he thought would work), and some a cord built into them that provided some other type of connection (that I guess would not work as far as he knew).
    Can anyone tell me if this would work?  Would my new iMac and its video card support the 30" Cinema display?  Would the result be as sharp and good-looking as my iMac's built-in 27" display, but only bigger (which is what I'm hoping for)?  Any advice is appreciated.
    I don't yet know many of the specifics of the 30" Cinema display I'm considering.  I know it is about 3 years old.  And here is a picture of the back of it:

    Yes, you should be able use the 30" Cinema Display with your new iMac without problems. You'll need a mini-DisplayPort to Dual-Link DVI adapter:

    I haven't had the 30" myself to test so I don't know if there any caveats. Perhaps someone else here will have personal experience.
    Regards.

  • 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!

    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.

  • Acrylic 20" Cinema Display with new MacPro

    As I read the posts here, to use the old cinema display with an ADC connector I will need to buy Apple DVI to ADC adapter to connect my 20" cinema display with ADC to the new MacPro?
    This new DVI to ADC adapter provides power for the cinema display as I understand which is why it's so expensive whereas when cinema display was connected to my Powermac G5 the power came thru the ADC connection?
    Is this correct?

    I am trying to connect a 24" cinema display with mini display port cable to a 24" imac with a displayport - is there a cable for this as these two connections are two different sizes

    Hi Gilly,
    I have no proof, but I think it will not work with an adapter, only Mini Display Port or Thunderbolt.

  • Sharing Cinema display with a PC

    Is there a way to share (via a swith box) my 20" cinema display with a PC. I know that there are DVI switchers but do they support the fact that the MAC display is powered through the connector interface aand that the firewire and usb is on the same connector as well???
    Thanks

    The DVI connector does not carry the power to the display. The cable from the display carries the power, USB, FireWire, and digital signals. At the computer end it is split into separate cables with plugs for USB, FireWire, power and DVI.. The switch would go between this DVI plug and the DVI connector on the computer's video card. The power would not go though the switch. The fancier switches will also have sockets to switch the UBS as well, so a keyboard and mouse plugged into the display will switch to the computer using it. This will also allow computer control of the display brightness.

  • CAN I USE MYApple Cinema Displays WITH MY MAC BOOK PRO

    CAN I USE MYApple Cinema Displays WITH MY 13"mac book pro

    Your 2014 MacBook Pro should have 2 Thunderbolt ports and 1 HDMI port.  We need to find out what plug your Cinema Display has.
    Does the Plug look like this:
    http://www.bluejeanscable.com/store/dvi-cables/dviiplug.jpg
    If so, then its a DVI connector.   And you would need a Thunderbolt/Mini Display Port to DVI adapter.
    http://store.apple.com/us/product/MB570Z/B/mini-displayport-to-dvi-adapter
    If not, look on the underside of the Display's frame or base/stand, there should be a model number there.

  • 30'' Cinema Display with mini-display-port to dual link DVI adapter usb hub

    Hi all, I don't know if any one of you experience this issue and can help me.
    I am using an unibody macbook pro (late2008 model) to connect to a 30'' cinema display via the famous $100 mini diaplay port to dual link DVI adapter. I have connected the usb cable from the ACD to the adapter and the usb cable of the adapter to my macbook pro. This setting works fine under OSX 10.5.7.
    When I am using Windows Vista under bootcamp the USB hub on the back of the ACD doesn't work. The device manager of Vista shows an excalmatory mark besides the device "Generic usb hub"; and it reports a problem of "the device cannot be started".
    I doubted this problem is due to Windows cannot recognise the $100 adapter as a "generic usb hub"; and apple has not release a driver for this $100 adapter for windows.
    Since my MBP only has 2 usb ports and the $100 adapter already occupied one, it would be very much helpful if the usb hub of the ACD can work just like in OSX. Can anyone think of any suggestion?
    Much appreciated for reading this post and thank you.

    i don't have an answer for you, but i feel your pain. very frustrating when this happens with Apple products and Vista/Bootcamp. wish they were more compatible, for it would make things so much easier for the consumer.

  • Original 22" Cinema Display and G5 Dual-Core Machine

    Good Morning, All!
    Is there a special adapter or converter I need to run my old 22" Cinema Display on my G5? I had to go back to the Dr. Bot I had when I had the monitor on a G4 450. With the arrival of the G4 933, I was happily able to do away with the Dr. Bot "octopus" and take full advantage of all the display on-board stuff (power switch, USB ports, etc.) However, the new dual-core has forced me back to that friggin' Dr. Bot, even though the G5 books says it's ready for ALL Cinema displays. Well, obviously not mine.
    A part number and a place to purchase would be most appreciated!!! I got spoiled to the power switch on the monitor. It was really rather dumb for Apple to put a metal start-up button on the front panel of the G5. With the air as dry as it is right now, the static is horrible and I don't like giving the machine a jolt when I started up in the morning. I find myself having to ground to something before I ever touch the machine these days.

    Hi,
    Well I have just bought a Quad G5 that I was gonna
    use with my old DVI equipped 22in Cinema Display and
    now discover that the connector on the display has
    more pins than the connector on the video card. How
    am I supposed to get around that?!
    Are you sure the display is DVI (screw knobs), and not ADC (clips)?
    If it is DVI and has six round pins (2 X 3) in the middle that are not on the video card connector, the extra pins are for dual link, which is only used on the 30" display. Depending on which video card you have, one or both connectors may be dual link, but you don't need the extra pins for the 22" display.

  • Using a 30" Cinema Display with new Mac Pro

    Hello Everyone:
    I just purchased, and waiting to arrive a new 2014 8 core Mac Pro which is an upgrade to my 2009 quad core Mac Pro. I currently use a 30 inch Apple Cinema display which has the DVI connection. I was thinking that I would use a DVI to HDMI adapter and plug the 30" into the HDMI port on the new Mac Pro. I have since heard that people have been having issues with this older monitor getting it to work properly with the new mac pro. some have suggested buy the $99 mini display port to DVI adapter and using that, but I don't believe there is a mini display port on the new mac pro.
    I have considered buying a new thunderbolt display because I am assuming that it will have a much better image quality than the older 30 in display but I hate the fact that it's a 27" and I would be giving up the 3" in size. I do a lot of video and audio recording editing and love the extra screen real-estate.  Can anyone confirm a couple of things for me?
    1. Will the 30 inch display work with a new mac pro and can I use the DVI to HDMI adapter?
    2. Does the new Thunderbolt display have a much better image quality than the 30 in display and because its newer, will look that much better with the mach pro?
    Thank you in advance.

    1. Will the 30 inch display work with a new Mac Pro?
    Yes.
    Can I use the DVI to HDMI adapter?
    Not if you want full resolution.  You need a Mini DisplayPort to dual-link DVI adapter
    <http://store.apple.com/us/product/MB571Z/A/mini-displayport-to-dual-link-dvi-ada pter>
    It plugs into a Thunderbolt port (and USB port) on the computer.
    2. Does the new Thunderbolt display have a much better image quality than the 30 in display and because its newer, will look that much better with the Mac Pro?
    No, it has more pixels (in the vertical direction), but they are spaced a bit more apart, so you don't want  to be as close to the display.

  • Using 2005 30" Cinema display with new mac pro

    I will order a new MacPro to replace my Mac Pro 1.1 immediately upon release.  I also have a 30" Cinema Display version 2005.  It's interface with the existing Mac Pro is three cable hookup:  DVI, USB and Firewire 400.  By connecting the Cinema display using a bunch of adaptors, can I make the display work with the new MacPro until a good 4K display is out there?  Alternatively, I'll have to buy a new display from current technology or the few 4k's available today.
    Thanks for your help.

  • Using Cinema Display with mid-2010 MBP, post-Yosemite:  corrupted MBP screen

    For a couple years I've been using a 27" Cinema Display attached to my mid-2010 MacBook Pro 15".  The dual-display setup works great for my home setup.
    However, since upgrading to Yosemite, the MBP display often completely corrupts and reverts to complete gibberish, with fragments of the UI and desktop littered all about the screen.  Dragging a window over to that screen usually "redraws" it sufficiently enough to keep working, but soon the problem re-appears.  The screen of the CInema Display (my main working area) never corrupts, only the MBP screen.
    My setup worked great in Mavericks, but something in Yosemite isn't driving both displays properly.  Can anything be done, aside from downgrading to Mavericks?
    Andy

    I am having this exact same problem.  2010 iMac with NVIDIA GeForce 9400 256MB.  I have it hooked to a 30" display through a DisplayPort to DVI-D adapter.  The 30" is fine, but I have graphical corruption constantly on the main iMac screen.
    This all started as soon as I updated to Yosemite a couple days ago.

  • Cinema display with mac book pro 15" using bootcamp

    Hi all, thank you in advance for answering my question. I just got a new mac book pro 15inch with the new cinema display, i am gonna use bootcamp to install windows vista, y question is will i still be able to use the cinema display when i am in windows system? thank you

    I have the same set up, but I must be doing something wrong, because when I set up the monitor to mirror the laptop the 24" LED screen is blurry and bright. When I have it set up as dual view the 24" LED screen looks good, yet, I have to drag everything over to the larger screen.
    How do I set it up as primary screen? Or make mirror screen work?
    Thanks!!!
