What is a dual-link DVI port?

I have a DVI port in my ancient Powerbook G4 that I use to connect an LG LCD monitor. Can I use the same cable to connect the LG to a 2009 Mac Pro or do I need some type of adapter?

As far as I know, you only need "dual-link" DVI if you are connecting a 30" monitor. If your LCD is smaller than that, the ports on the PowerBook and the Mac Pro should work just as well for that monitor.
I bought a 20" Apple Cinema monitor (it has DVI) originally to use with my PowerBook G4. It's now attached to my Mac Pro, no adapter needed just plug it in to the Mac Pro DVI port.

  • ATI 9600 Pro Mac & PC Ed. - Which is the Dual Link DVI Port?

    I just bought an ATI Radeon 9600 Pro Mac & PC edition Video Card:
    http://www.ati.com/products/radeon9600/radeon9600propcmac/index.html
    This card features 2 DVI ports - one of them dual link.
    Maybe I'm just blind, but I've been looking around everywhere trying to figure out which DVI port is the dual link. Does anyone know?
    Any help will be appreciated.
    PowerMac G5 dual 1.8, TiBook 550, Compaq V2000 1.68 Turion   Mac OS X (10.4.5)   G5-160+120gb,1.5gb,4xSD | PBook-20gb,768mb,Combo | V2000-80,512,8xDL+Lightscribe

    There is a small "1" stamped in the sheet metal next to the single link DVI connector, and a small "2" next to the dual link DVI connector. The single link is closer to the motherboard.
    There should be a PDF Users Guide on the Mac CD that came with the board. Page 17 shows the connectors.

  • Is anyone having stuttering problems on the ati 5870 with the mini dislplayport connected monitor when you turn off the display connected to the Dual-link DVI port?

    hey i have a ATI 5870 and when ever i turn the monitor connected to the dual_link DVI port the display connected to one of the mini display port shutters with everything on the screen Video, Mouse movement ect, any ideas ?

    Not sure what you are trying to do.  I interpret what you are saying is that you have a monitor connected to the DVI port and another to the mini displayport (mDP).  Are you physically trying to turn the one connected to the DVI port off (and on) causing the one on the mDP port to "shutter"?  If so, take a look at SwitchResX.  It will allow you to programmatically turn monitors on or off.  Maybe that will cure the problem.
    Of course if I am misinterpreting what you are saying ignore this post.

  • Cinema 30" - What is the Dual Link DVI Cable Length?

    Planning my install, but can't find out how long the DVI cable is in length on the 30" Cinema display.
    Anyone know or can measure their cable?
    Thanks!
    Dave

    Cable is 2m. Not sure what the +/- tolerance is, but figure 5cm. And the breakout ends for USB, etc. are a little bit longer, just enough to allow them to reach their mating ports on a system.

  • How do I connect dual link dvi to hdmi so I can use my TV as a monitor?

    I have tried to google this for some time and have gotten nothing but conflicting responses.  I have a 15" macbook pro with a dual link dvi port.  I want to connect it to the hdmi port on my HDTV.  What do I need to make that happen?
    Is there actually an adapter from dual link dvi to hdmi or will I need multiple devices for this?
    thank you,

    Hi there,
    Thanks for the response...I think I have a 2007 version.  My output is the DVI-I.  It looks like maybe the dvi-i male to hdmi female might work?  I don't see much in the way of dvi-i, there are more dvi-d around it appears.
    This or many others like it will work, then a standard HDMI cable.

    nice, it's always the ones that fail to do a basic search that are the most hostile. i'm sorry you thought my asking you what monitor was 'drilling' my crystal ball was broken at the time.
    there are TONS of posts and articles out there with your answer, but since that may be too hard for you, i've provided some here.

  • Apple's Mini Displayport to Dual link DVI Adapter... What to do?

    So i'm doing a new setup with 6 monitors (Eyefinity 6), and i've got everything set up so far... Except for adapters. So i went and got 4 Of those Accel MDP to DVI SL adapters, in addition to the two passive that come with a card. Didn't work...
    So i got two Apple Mini Displayport to Dual Link DVI Adapters... And boy, I should have read the reviews before buying them. They are giving me very strange issues. Not going above 800X600, serious graphics corruption on the monitors connected to the apple adapters, or odd resolutions that the monitors do not support.
    So i'm wondering what to do. If possible, i'd like to get these to work somehow, as i got them for cheaper than other MDP to Dual Link adapters. They are both plugged in to the USB ports of my mac pro.
    I've also heard something about a firmware version, 1.2 or something. Is there a way to update the firmware of these?
    Thanks
    -C

    I'm using the Sapphire 5870 Eyefinity 6 Edition. Two of them in crossfire, supplied their power from an external 1200W PSU Devoted just to them.
    It's under Windows 7, running on my mac Pro 2.26.
    Hooking them both up to a iphone cube-wall charger keeps them up and running, but they fail to supply the necessary resolution (One only registers 640X The other dimension, the other thinks the monitor is 1920X1080, when it really is 1920X1200).
    Not to mention, attempting to use any of them in an extended desktop led to a MACHINECHECKEXCEPTION bsod.
    I can't find any sign of what the whole issue is, i'm having issues with the eyefinity setup itself too, so i dunno if its the adapters, the card, drivers, or what. The apple adapters are acting up on me though.

  • Mini Display Port to Dual Link DVI Does Not Work Right

    Somebody said here that this was an isolated problem. Well, I just got my new MacBook Pro 15", used the adapter to hook to the 30" Dell monitor, and it works a few minutes, then the screen distorts.
    Count me among the isolated problems- it is beginning not to look isolated.
    Now, do I wait on Apple to fix the problem, or do I return the MacBook Pro while still in the return period?

    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.

  • Connect to Dual-Link DVI-D port on monitor using DVI-D to VGA adapter -- getting no signal

    I have a T400.  I am trying to connect to a dual-link DVI-D port on my LG monitor via the VGA port on my T400 laptop. I bought a DVI-D to VGA adapter, but I am getting no signal. 
    Do I need some other method or adapter or cable?  Monitor works fine for VGA to VGA connection.
    Solved!
    Go to Solution.

    I happened onto this thread while searching for a way to connect my T400 to my wife's 27" iMac. What I learned thus far is that Atlona makes a device (AT-DP400) that will convert dual link DVI to Mini DisplayPort. But Atlona says that one's graphic card must support 2560x1440. The T400 doesn't have a DVI out (nor does my current docking station), but it sounds like one can get a docking station that does. But that won't help if my card won't support 2560x1440. So are you saying that there is no way I will be able to use the 27" iMac as a monitor for the T400?

  • 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,

  • 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.

  • HT204149 What is the maximum resolution available for use with the Apple Mini DisplayPort to Dual-Link DVI adapter?

    What is the maximum resolution available for use with the Apple Mini DisplayPort to Dual-Link DVI adapter?

    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 !

  • What does the 'Dual' in Dual-Link DVI Adapter refer to?

    We purchased a 'Mini Display Port to Dual-Link DVI Adapter thinking it meant we could split the output to two monitors such as the Matrox TripleHead2Go or Matrox DualHead2Go.
    Having received it, we are unable to determine the advantage of using this product other than a normal Mini to DVI adapter. Hopefully the Dual doesn't refer to the addition of a USB port. Thanks for any replies.
    --Bruce D. Meyer

    DVI uses a transmission format called "transmission minimized differential signaling" (TMDS). In the DVI standard, single-link means that there's one 165MHz TMDS transmitters connected, and dual-link means that there is 2 (doubling the bandwidth of the cable). So, a single-link cable can transmit 1920x1200 at 60 Hz, whereas a dual-link can transmit 2560 x 1600 at 60 Hz (about 1.8x the resolution).
    So, a dual-link cable will allow you to use higher resolutions and frequencies (though common LCD panels are locked at 60 Hz) than a single-link one.

  • 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
