ADC displays, 10.4.11 and MDD

I've been running a dual 1.25 PowerMac G4 with a 23" Cinema display (ADC) for about 8 years now without a single hint of trouble. No room for the 23" ADC monitor on my desk anymore (making room for 30" w/MacPro), so I picked up a 17" ADC Studio display and wall-mounted it (actually, I have two of these).
Trouble is, my MDD G4 refuses to turn on with either 17" ADC Studio display connected. (LED only blinks once, machine never goes on.) The 23" Cinema works perfectly (as always) and a 15" ADC Studio display works, too. Both 17" ADC Studio displays work fine connected to an old G4 Cube, but both prevent my MDD from starting up. I always thought any Apple ADC display would work on the G4 MDD - no? What makes the 17" Studio displays different? Video card is the OEM ATI Radeon 9000 Pro (1 ADC, 1 DVI).
What am I missing? All four displays work, only the combination of MDD and 17" Studio display fails....?

Tried to startup from a great old SCSI drive running OS9, Monitors CDEV set to proper resolution, etc.
Computer's power button LED only lights when pressed, nothing else happens.
It's a hardware issue, simultaneous with two identical 17" ADC Studio Displays? I have an ADC to DVI converter, but what's the point of trying that? So..... why do they both work perfectly when plugged into a (10.3) G4 Cube?! What's the diff between G4 MDD (Radeon 9000 Pro) and G4 Cube's AGP cards (32MB VRAM 1280x1024 ATI RV200? - upgrade from OEM card)....?

  • DVI to ADC Adapter a 12" Powerbook and an Apple Studio Display 15"

    hello,
    i am trying to hook up a 12" powerbook with a DVI to ADC adapter to an Apple Studio Display 15".
    i´m just about to buy a used 15" display on ebay.
    i was wondering if this is working out together. in the apple store there are two DVI to ADC adapters at different prices and displays supported?
    so if anybody could help me out please let me know!!!!
    thank you very much
    regards, g.

    Hi
    unfortunately I think the Apple store have sold you the wrong item.
    I'm almost certain the DVI to ADC adapter only works with ADC based flat panel displays. DVI ports can output digital or analogue signals (or a combination of the two). The adapter seems to provide digital, which is why it works with the LCD displays, but not analogue, which is why it doesn't work with the CRT displays.
    Confusingly Apple did a 17" Studio display both as a CRT and LCD.
    Dr. Bott do a similar adapter but they explicitly state it's not compatible with the 17" CRT.
    Unfortunately I'm not sure there's a solution, as the display has an ADC connector yet I'm not aware of any adapters available that will work.

  • Dual ADC displays and a vid card w/ no ADC ?

    Hi.
    I've got a PowerMac G4 with an ATI Radeon 9800 Pro vid. card. I bought it when I purchased my 17" Apple display not knowing that the Apple display had its own connector that required me to but a $99 adaptor that also requires a power cord!
    Anyway, my old CRT (that acted as my 2nd display on the G4) finally died. I purchased a nice 15" Apple display, but apparently forgot to consider the ADC connection.
    I need a cheap, fast solution.
    I've got a G4 with the 9800 Radeon which has a DVI and VGA connection.
    By the way, does having 128MB DDR of video ram help with rendering time??
    Ok, back to the original question.
    I also have the original video card that came with the PowerMac G4 1.2mhz Quicksilver. I believe it's an 9000 Radeon. It's got an ADC and VGA connection.
    How can I setup a dual display on the G4 with the two Apple displays? Both are ADC and neither card has (2) ADC connections.
    I've got two ADC to DVI convertors and I have the VGA to DVI convertor that came with my 17" apple display, but the DVI end doesnt match the DVI end on the 2nd ADC to DVI convertor.
    Any suggestions? Is there a dual ADC video card?

    Hi
    As far as I'm aware, the Radeon 9000 that came as the stock graphics card in certain PowerMacs had an ADC connector and a DVI connector. It also came with a DVI to VGA adapter. If this is the case you should be able to attach one monitor directly to the ADC connector and the other to the DVI connector using the $99 DVI to ADC adapter. You'd be losing the benefit of the Radeon 9800 though.
    Unfortunately there aren't any graphics cards with dual ADC connectors, as the card (and AGP slot) would have to provide enough juice to power two monitors. The options seem to be:
    1. One AGP card with an ADC connector and DVI connector, which would require one DVI to ADC adapter, such as the Radeon 9000.
    2. One AGP card with two DVI connectors, which would require two DVI to ADC adapters, such as the Radeon 9600 retail version. Mines worked perfectly, although there do seem to be problems with it in certain Quicksilvers and Digital Audio G4s.
    3. One AGP card with a DVI connector, which would require a DVI to ADC adapter, such as your existing Radeon 9800 and one PCI card with a DVI connector, which would also require a DVI to ADC adapter, such as the Radeon 9200. An AGP card with an ADC connector would also work but seems pointless given you've already got the 9800 and adapter.
    Unfortunately I'm not sure there is a really cheap solution. As already mentioned, there are VGA to DVI converter boxes on the market, but they're incredibly expensive and you'd be converting from digital to analogue and back to digital, with some loss of quality.

  • Matrox DualHead2Go and ADC Display?

    I have an older 17" acrylic display with that big ADC-DVI adapter. I'm currently using my Macbook Pro (ATI X1600 video card, Dual-Link DVI connector) with a surprisingly good HP VGA panel, the same resolution as the Cinema Display.
    Has anyone had any luck with using an ADC monitor with the Matrox DualHead2Go? I'd like to connect both of these displays to my MBP, and have heard concerns about compatibility with certain devices and the ADC adapter. Secondly, does anyone know if the DualHead2Go can support mismatched signals, at the same resolution(1x DVI, 1x VGA).
    I suspect I need the Digital Version, but it seems that because the signal has to turn into VGA first, it may not work with the ADC display. So third, is the Macbook Pro capable of connecting to the newer DisplayPort version of the DualHead2Go? Assuming someone makes a DVI-Displayport connector.

    The idea behind the DualHead2Go is that the two displays be matching displays, so mismatched resolution won't work AFAIK. But you can ask Matrox that question to be sure.
    If your MBP has DVI for its output, then it won't be compatible with the DisplayPort version of the the DualHead2Go.

  • Powermac G4 ADC Display Problem

    Hi,
    I just bought a 17" Studio (LCD Flat Panel) Display. I was suprised to see that everything is powered by one cable because I though that I needed separate cables. I installed an AGP Graphics Card from another Powermac G4 MDD. The Powermac G4 I installed the card into is a Powermac G4 AGP. So, I plugged the display into the ADC Port of my card and nothing happened. I can get my DVI monitor working A++ but can't even get the Studio Display to do anything. I really need help, as this is going to be my main Photoshop Mac. Any help is appreciated.
    Thanks,
    Austin L.

    Just a note to avoid any possible confusion, you don't want an ADC->DVI converter, you want a DVI->ADC converter that has it's own 25V power supply brick.
    Wrong one...
    Right one...
    I don't think I've seen one lately go for less than $130...

    In which case a new/better DVI Monitor may be the way to go.

  • HT1825 Can I connect post cinema displays to my G4 and how?

    Can I connect post cinema displays to my G4 and how?

    You can use newer monitors but there are different ways to connect.
    It all depends on the video card installed in your computer. Different model cards had different ports. My G4 MDD has the ATI Radeon 9000 with one ADC port (abandoned technology) and one DVI port (useful technology). So we need to either see the description of your graphics card from System Profiler >Graphics/displays, a photo of the ports on your card, or both.
    As long as you find a monitor that shares the kind of ports on your Mac, you will be fine. I have a 2008-vintage LCD monitor on that circa 2003 MDD of mine. The MDD shipped with an Apple DVI-to-VGA adaptor so I can connect any monitor with DVI or VGA ports.
    There is an inconsistency in your equipment profile: No PowerMac can run OS 10.6. Please do "About this Mac" and verify your processor type and Mac OS version. Then you can edit your profile to avoid future confusion.

    Hi Gary,
    The G4 AGP graphics model is pre-ADC and its motherboard will not support a video card with a native ADC port. The ADC ports on such cards draw their power and USB feed via an extra leg on the card that fits into an extra slot at one end of the AGP slot on the computer motherboard. Your computer does not have this extra slot.
    To run an ADC display off your computer, you can run a video card with a DVI output, then use a DVI to ADC adaptor such as this one:
    http://www.drbott.com/prod/db.lasso?code=0111-DVAD
    You can use VGA to ADC adaptors, but they are much more expensive (than a DVI to ADC adaptor plus another video card), and don't give as good a result.
    Cheers!

  • Mac Pro Adc Displays

    Hi
    Since Friday i have a Mac Pro.
    I connect my old Adc Cinema Display, with an ADC-DVI Adapter.
    Everything work fine.
    I have another 17" ADC Display.
    Is it possible to connect two ADC Displays, with two ADC-DVI Adaperts to the NVIDIA GeForce 7300 GT Graphiccard without a problem?
    Thanks
    Greetings from Vienna

    I'm seeing a lot of this.
    Pay attention closely.
    If you have an ADC display and you want to connect it to the new Mac Pro, you must buy a different adapter. The ones supplied with the Mac Pro do not connect an ADC display to a DVI Mac Pro. You need to buy one that has a power supply and a USB port. DrBott and Apple make them.

  • DVI display port/ADC display port bottleneck!

    My G5 dual came with ONE DVI display port and ONE ADC display port. I wish to add another monitor for editing purposes. My current monitor is an NEC multi-sync, which uses up the DVI port...leaving the ADC port empty and useless.
    1. Am I forced to purchase an Apple Cinema Display?
    2. Would it be more frugal to purchase another video card?
    3. Can I make this work even though I have bought every 'adaptor' under the sun and the ADC port is still useless?
    4. It there a 3d party adaptor that can use the ADC port to use an NTSC (television) device as 2nd monitor?
    thanx

    Hey U-dog,
    I went to see Mr. Whooppee at Dr. Botts and ordered the shiny new DVI Extractor II (sounds like I'm back in the hackin biz) and again, I'll hold Sweet Polly or Breezly bruin hostage if this (last attempt at adaptors[sold for g-4s]) DOGgone thang don't work. So keep an eye out at WDOG or the local tundra if you REALLY care about those toons!
    fingers crossed,

  • IMac & ADC display

    I have an older Apple LCD display with the ADC connector, which I can use with my (even older) PowerMac. It's a great monitor, and I'd hate to have it just sit around when I upgrade...hopefully to an iMac.
    I know there are connectors for mini-DVI to VGA or DVI, but would it be possible to go from mini-DVI to ADC? Or would a mini-DVI to DVI and then a DVI to ADC adapter have to be the way to go? Has anyone tried this before?

    Yes, thanks. But has anyone actually daisy-chained several connectors together to make sure it works with an ADC display? I just don't want to spend the $100+ and find out that it doesn't work. In theory it seems like it should, but one can never fully tell with technology.

  • Connecting 2 15" ADC Displays to G5

    I already have a 15" ADC display & have another one on the way. I require the use of a seperate display for using music software etc. Can anyone tell me how I can connect the extra display to my G5? Do I need an extra connection?

    I have the same problem with a 9800 AGP and 9200 PCI card.
    Things start to go wonky.

    Hi Guys,
    Checked the mini display with Dell flat monitor and Samsung LCD tv , works perfect. The VGA port of my old monitor is not in good condition.
