Plugging USB from cinema display to dual-link DVI adapter shuts-off adapter

i have a macbookpro and 30" cinema display. i had been using the $100 minidisplayport-to-duallinkDVI adapter to connect my monitor but now whenever i plug the USB from the monitor into the adapter (to use the monitor as a USB hub) it  kills the power to the monitor! does anyone know what the problem is here? it seems to have gotten worse and worse over time and now i cannot ever get it to work no matter how many times i replug things... causing my studio to be quite disconnected. does anyone have any information on this issue?

There just so much power that can be delivered to the usb buss.  You probably need a powered usb hub.

  • 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.

  • Macbook Pro with Retina wont detect monitor on mini display port to dual-link dvi adapter

    So after reading Jeff Atwood's post, I decided to jump and give it a shot. So this week I got my monitor in from Korea, and I already had my Apple mini display port to dual-link dvi adapter, hooked everything up - and nothing. Monitor doesnt show a signal, and no display shows up in user preferences.
    To verify the monitor actually works, i plugged it into my windows box - and boom, right away there it is in all its glory. So I called apple support, after spending about an hour going through the "are you sure its plugged in stuff", the tech finally admitted to being stumped and blamed the adapter. Not to be deterred, I then went to my local apple store and talked them into trying their adapter to rule out the adapter - regardless of the adapter, the mbp wont detect the monitor.
    Just for fun, i tried my old single mini displayport to single dvi, the monitor is recognized, but that obviously cant drive the right resolution, so i just get a backlight. Same deal when i try the hdmi port with a hdmi to dual-link dvi adapter on the end of it. Also tried display port to the same hdmi with adapter on it (the joys of working in a dev shop - cables to test everywhere)
    I have read / tried a ton of things:
    re-installed / uninstalled air display, just to be sure it was gone. went through all my apps just to see if there is anything like this i could think would be effecting it
    install gfxCardStatus to ensure i am on the nvidia (discrete) and not the internal card
    Played with different settings on SwitchResX to try to force the res over hdmi - no love - os rejected each one
    I bought the monoprice adapter wondering if it was just the apple adapter since the apple adapter has been panned, no love from it either
    Reset the PRAM countless times
    I have two other adapters coming in to test with in a day or two - maybe one of those will be magic, but at this point i kinda think its software on the mac. My Spec:
    I am running Mountain Lion with all the latest updates
    New MBP with Retina (2.6g processor, 16gig ram, nvidia video card)
    Here is the ebay link to the monitor
    Now the other weird thing is pretty much universally these auctions say the monitors cant be run on a laptop - which makes no sense to me, because its just a connection, if the video card is strong enough (which my machine better be) it shouldnt matter the source. The listing mentions its a "by-pass" monitor, which is something I and google have never heard of.
    So any sage words to make my day?

    Magic was, I have to have the adpter plugged into the mac, let it recognize all with the monitor powered off.
    then power on the monitor, and boom gloriousness
    For future generations, setup that works:
    1) MacBook Pro with Retina
    2) Monitor From Korea (example auction)
    3) Accell Mini DisplayPort to Dual-Link DVI Active adapter (amazon)
    4) Boot mac, plug in adapter, let it recognize the monitor, power on monitor

  • Mini Display Port to Dual-Link DVI Adapter: No image with 3840x1200

    Hi!
    I ordered the Mini Display Port to Dual-Link DVI Adapter regardless of the many complaints that it's not working in order to connect my new MacBook Pro to my Matrox TripleHead2Go. This Graphics Expansion Module normally allows to use two 1920x1200 monitors when connected to Dual-Link DVI (3840x1200). It works fine on my old MacBook Pro (with Dual-Link DVI output), but with my new MacBook Pro the first monitor just turns black and the second tells "Out of Range" when using the Mini Display Port to Dual-Link DVI adapter.
    When I am reducing the resolution to 3360x1050 (2x1680x1050) it works, but this is not the native resolution of my two 24'' monitors and therefore is useless.
    The Matrox Support only told me that the new MacBook Pro with Mini Display Port is not supported, but as it's working for 2x1680x1050 with the Dual-Link DVI adapter, I was wondering if the Mini Display Port to Dual-Link DVI Adapter could be the problem.
    Any input welcome.
    Thank you in advance.
    Cheers,
    Matthias

    Hi, Matt, and welcome to Apple Discussions.
    The Matrox Support only told me that the new MacBook Pro with Mini Display Port is not supported, but as it's working for 2x1680x1050 with the Dual-Link DVI adapter, I was wondering if the Mini Display Port to Dual-Link DVI Adapter could be the problem.
    I suspect that what Matrox Support meant when they said "not supported" was, in fact, "not supported": i.e., they've tried it and it doesn't work satisfactorily. You've tried it too, and found that to be true. Now you just need to come to terms with the fact. Matrox is quite open about it; it's not a secret. See the 9400M/9600MGT MacBook Pro entry in this compatibility table from Matrox's web site:

  • Switching between Dell 4K display and Apple Mini DisplayPort To Dual-Link DVI Adapter

    Hi All,
    I've recently upgraded my home setup to a Dell 4K display (Dell P2815Q), which since the 10.9.3 update work as expected.
    However the downside is that my office setup uses a Mini displayport to Dual-Link DVI adapter (Firmware version 1.03) and a Dell 30" display (2560x1600), which will not work without a reboot after using the 4K display. If I use the 4K display after using the Dual-Link DVI adapter it works fine.
    Is this a know issue ? If not, I'm happy to provide some more diagnostic information to help resolve the issue.

    http://www.everymac.com/ says:
    *This model supports a simultaneous maximum resolution up to 2560x1600 on two external displays via Thunderbolt. Alternately, it can support a single display up to 2560x1600 via Thunderbolt and a single 1080p display at up to 60 Hz, 3840x2160 at 30 Hz, or 4096x2160 at 24 Hz via HDMI.
    DVI is not mentioned at all.  You probably need to connect to the display via HDMI to get the 4096x2160 resolution.

  • Display port Dual link DVI to Gateway XHD3000

    The *displayport to dual-link dvi adapter* I bought doesn't seem to work with resolutions > 1920x1200. My Gateway XHD3000 monitor supports upto 2560x1600 but I can't set this resolution in the system preferences. I have set my power setting to "+Better Performance+" hoping the other GPU would be used but still the same lower resolution.
    I'm using the Dual-link cable that came with my monitor.
    I actually have 2 systems exactly the same with this problem.

    Here is what the Gateway Tech support had to say. *Very helpful*....punt!

    Dear Emmett Bearden,
    Thank you for contacting Gateway. I apologize for the inconvenience that you have experienced. If you cannot set the monitor resolution greater than 1920 x 1200 or up to 2560 x 1600, this may occur if your MacBook Pro does not support dual-DVI output, does not support this kind of ultra-high resolution, or does not have the latest video driver. I suggest you please first contact Apple's technical support, to inquire if the MacBook Pro supports this resolution, or if they have a workaround for this problem.
    Respectfully,
    Gateway Online Technical Support
    Customer (Emmett Bearden) - 01/07/2009 12:26 PM
    Using my Apple MacBook Pro I'm unable to display a resolution greater that 1920x1200. I bought this monitor for the 2560x1600 resolution. My connection is a dual dvi using the cable that came with the monitor.

  • Mini DisplayPort to Dual-Link DVI Adapter

    Hi, I am using the Apple Mini DisplayPort to Dual-Link DVI adapter to connect my 30" Apple Cinema Display (Aluminum) to my MacBook Pro 13" Retina, I am passing through the Belkin Thunderbolt Dock, so I connect the Dock to the MBP via the Thunderbolt port and then I connect the Mini DisplayPort to Dual-Link DVI adapter to the Belkin Dock and then to the Apple Cinema 30".
    One of the issues I am having is that with the Cinema Display I am working at 2560 x 1600 resolution, much larger than the native MBP resolution, I am also using my apps in Full Screen mode, so when I disconnect from the Cinema Display and go back to use the MBP the apps in full screen mode still are at a higher resolution than the native MBP resolution and they are off the screen. Is there a way to manage a profile with different resolution so the Mac OS will switch automatically resolutions?
    Also does the Apple Mini DisplayPort to Dual-Link DVI adapter usb cable supports USB 3.0 ?
    Thanks

    Hey guys,
    I found out an answer by myself...
    The missing link : the MacBook Pro needs to be powered... as in you need to plug the charger in...
    In conclusion, you simply plug everything, turn on the MacBook Pro, close the lid, and there you go !

  • MBP + Mini DisplayPort to Dual-Link DVI Adapter + 30" = blue flickering

    Hi everyone,
    I was wondering if anyone has found a solution to this problem? I use an Apple 30" Cinema Display and it worked fine with my Late 2007 MBP. Now I got a new Core i7 MBP and the Mini DisplayPort to Dual-Link DVI Adapter. At first all works fine, but after a while of use I get blue (and sometimes also green) flickering pixels in areas that are supposed to be black. This does usually not matter while working, but watching movies for example is completely unbearable.
    I’ve read a few threads, but most seem to have different problems like 1/3 of the screen flickering or the external display going completely off for a second. That is no issue over here. It is just that the longer I use my setup the more flickering gets added. At first I thought I don’t suffer from this, because it goes from practically flicker-free to totally weird flickering when everything is in use for more than a few minutes.
    I’ve set up the Computer Name screensaver. If I run it right after turning on my MBP all is fine. Running it again after 2-3 minutes of use shows the first blue pixels flickering. It does not need 30 minutes to arrive at what seems like more flickering isn’t possible anymore...
    Any recommendations or solutions are really welcome!
    Things I already tried:
    - different USB ports for both the adapter and the Cinema Display
    - other power outlets
    - powering the adapter from a USB hub or via an iPod wall charger
    Thanks

    I would even try out crazy adapter combinations if there were any available...
    At last! I’m quoting myself, because I finally found an alternative adapter which works! I have no more flickering pixels/lines. Black looks and stays completely black as it should! I can finally use dark backgrounds again and watching movies with black borders or dark areas is no longer a pain.
    The adapter was very hard to get. It currently is not sold here in Germany and I got it off eBay where there was only 1 available. I’m happy, because I got it for less than 90€ which is even a little cheaper than Apple’s flicker-creator.
    The adapter I now use is the Sapphire Active DisplayPort-to-(Dual-Link-)DVI adapter. It has a USB connector for power like Apple’s adapter. The only thing that’s added is the DisplayPort-to-Mini-DisplayPort cable since it is not available with Mini-DisplayPort. Here’s a picture of it:
    Hope this helps others, too!

    PS: This adapter seems to be normally meant for ATI’s GPUs in order to connect 3 displays which they call Eyefinity.

  • TS3232 I have the mini DisplayPort to Dual-Link DVI Adapter firmware 1.03 and I still have screen flickering issues

    I have the mini DisplayPort to Dual-Link DVI Adapter firmware 1.03 and I still have massive screen flickering issues on a Mac Mini 2012.
    I am using a Dell 30" monitor (it's the Samsung screen just rebranded) connected to a WD 4TB Thunderbolt drive connected to the Mac Mini.
    The screen is usable for the most part when I've just started the computer (although today I started having issues after a fresh restart) but if even just the screen goes to sleep, or the computer goes to sleep and I wake it later, I start to have massive flickering to black and occasionally to snow.
    The effect seems to be more likely to arise when I'm on heavy graphics-intensive websites or programs (eg, Tumblr feed with lots of GIF images or working in Adobe Premiere), but once it starts shutting down those programs has no effect, the screen keeps flickering wildly.
    The problem improved after the 1.03 firmware upgrade (for a while it was flickering uncontrollably ALL the time and was virtually unusable) but it has not gone away.
    Any suggestions would be very welcome, either for how to fix this issue or how to get Apple to, you know, let me TELL THEM that their adapter firmware fix has NOT solved the issue, since my phone support has expired. :/

    I have a new Mini DisplayPort to Dual-Link DVI Adapter to allow my original Apple 30" Cinema Display to connect to the new Mac Pro.  Shipped straight from Apple, it is firmware version 1.03.  I've never had flickering issues, but the display will often go black (possibly after a screen power save) and not come back.  when this happens I am still able to connect to and use the Mac via remote connection.  But the only way to get the screen back is either to unplug the adapter and plug it back in to the Mac, or to shut down and power up the Mac.  This may be a separate issue, so I'll also post it standalone...

    You've probably fallen into the nasty pothole created by the advent of HDCP compliant graphics on Apple computers and a mishmash of older and newer Apple gear that does/does not support HDCP.
    Ironically, if you were using an older Mac notebook (prior to late 2008), everything would play just fine because HDCP wouldn't come into play anywhere.
    That is my guess as to what is happening.
