Mini DVI-Adapter Not Working

Today I went to the Apple Store and got myself one of those fancy new Mini-DVI to DVI adapters, hoping it would work with my screen at home, which I had previously running on the Mini Displayport to VGA Adapter on my original MacBook.
Strangely, when I plugged the cable into the adapter, and into my computer, nothing happened. I did not get video on the screen, nor did my MacBook detect it. I have tried re-plugging the Mini-DVI adapter and clicking Detect Displays in the Displays Preferences multiple times, but no luck.
I have seen the screen work with DVI about a year ago, but that was on one of the original MacBook Pros. Am I better off returning this DVI adapter and instead buying a Mini-DVI to VGA Adapter?
Thanks for any help in resolving this problem.

I have a 22 inch ViewSonic that I got from a friend about a year ago. I did indeed plug the monitor directly into the adapter.
I brought my computer, adapter and cable all into the Apple Store, and they said it was all OK, but did replace my DVI adapter thinking it was probably defective. I got home, tested it on my monitor, but still not working. I tested it on a newer HP monitor that's on the family computer, and oddly it worked there.
A bit of research revealed that the adapter did not send Analog signals on DVI anymore, which confuses me, since the MacBook actually does have Analog signals on that port. I brought my DVI adapter in original packaging in to the Apple store again, and they replaced it with a VGA adapter for free, and sure enough, that solved the problem for me.
Lesson Learned - don't use DVI with older monitors, stay with VGA.

  • Mini-Displayport to DVI adapter not working, but Mini-Displayport to VGA and Thunderbolt work fine

    Mini-Displayport to DVI adapter not working, but Mini-Displayport to VGA and Thunderbolt work fine.
    This is a brand new MacBook Pro (15-inch, mid-2012) just received.  I suspect that this is a hardware problem as:
    The mini-displayport to DVI adapter and the external monitor that I am utilizing connect and operate just fine using my older MacBook Pro (mid-2010) with the same OS.
    The new MacBook Pro powers the external monitor with a mini-displayport to VGA adapater without issue.
    The new MacBook Pro powers an Apple Thunderbolt display without issue.
    Both MacBook Pro's are running OSX Lion 10.7.4.
    The only combination which does not work is the mini-displayport to DVI adapater used in conjunction with the brand new MacBook Pro (mid-2012).
    All adapters and components (mini-displayport adapters) are Apple retail adapter.
    I have tried several external monitors, including my Dell U2412m.
    When I connect the mini-displayport to DVI adapater to the new MacBook Pro (mid-2012), nothing happens. The external monitor reports "no signal" and attempts to go into sleep mode.  Using the "Detect displays" button has no effect, even when used multiple times.  Rebooting does not help, nor does resetting the SMC or PRAM.
    Any other suggestions before I take it to the Genius Bar?

    I turns out that the logic board of my MacBook Pro was faulty (despite being brand new).
    I took it to the Apple Store, presented the problem, and one of the Tech's came to the same conclusion that I had -- hardware failure.  Phone support was no help in the matter (and even told me that what I was trying to do wasn't a supported option, which is rediculous).  However, the Genius Bar did take care of the problem, and my MacBook Pro was back to me with a replaced logic board within a few days.
    Hope that htis helps.

  • Mini dvi to dvi adapter not working with monitor

    arright *** i got a mini dvi to dvi adapter which is connected to my vga monitor through a vga to dvi adapter. The computer recognizes the monitor in display preferences, but the monitor doesn't display anything it just sits in standby mode... any ideas why this isn't working? You'd think if the problem was going from vga-vga to dvi adapter-dvi to mini dvi adapter that it wouldn't even recognize the monitor but it does.
    well that *****, back to best buy to get the other one. Reason i got the dvi one is because i plan on getting a different monitor with dvi soon. But noo dvi adapter wont work with vga adapters.

    The mini-DVD to DVI adapter doesn't pass through the analog video signals needed for VGA, so won't work with a DVI to VGA adapter. All the control signals are there, so the display is recognized, but there will be no picture.
    They could have used a DVI-D connector on the adapter, instead of DVD-I, so the DVI to VGA adapter wouldn't even plug in, but then it couldn't be used with some non-Apple LCDs, that use DVD-I connecters.

  • Mini DVI does not work in windows

    I have no problem using the Mini DVI adapter in OSX but when I go into windows it does not work. Any suggestions would be greatly appreciated. The only reason why I use windows is for the TVUplayer, which currently has no version for OSX

    When you boot into Windows, you need to change graphics options to tell the OS to output to the External monitor. On the macbook is the intel GMA950 graphics chip and it comes with intel software when you install the drivers. If you go to control panel in Win XP, there is an intel section in there. You can then set the options to output to an external monitor either mirrored or extended desktop, and it will remember and do what you selected each time you boot into windows

  • Mini Display port DVI adapter not working on Thunderbolt Port

    For some time I've been using a mini display port to DVI adapter on an slightly older MBP to connect to my HD TV.  I recently purchased a MBP with a Thunderbolt port and when I try to connect it to my TV via my mini-display-port-DVI adapter things are not working properly.  The MBP is seeing the Philips TV but it isn't listing all the display modes and I'm not able to send any video to it.  Does the Thunderbolt port require a new display port to DVI adapter?

    Let me be clearer; I've got the MDP-DVI adapter connected to a cable that is DVI on one end and HDMI on the other.  I've got both laptops so I can compare side by side.  I plug in the MDP-DVI adapter to the old laptop and all works well; I plug it into the new laptop and while the laptop does see the TV, the display modes for it are all 1080p which is wrong I don't see any desktop image on the TV unlike when I plug it into the older laptop.  This is very disappointing as I expect things to just work with Apple products.

  • Mini displayport to dvi adapter not working

    hello,
    I have both a 2008 Mac Pro tower with 2 Apple Cinema Displays, and a newer MacBook Pro that I'd like to hook up to one of the monitors.
    The 2 monitors are both DVI, so I bought a mini displayport adapter to plug into the thunderbold port on the MacBook Pro and the other end to the monitor.
    When I plug it all in, I get no video on the monitor. I am sure the monitor works, I'm sure the cables work (from the monitor), not sure about the adapter (I just bought it, so it could be bad)....
    I did see quite a bit of the same issue online, thought I couldn't find any help in fixing it.... short of driving back to the apple store and replacing the adapter, I'm wondering if there's anything else I should do to trouble shoot this....
    I've restarted the computer, checked all connections, nada....
    help??

    The problem was simple: my laptop wasn't plugged in...
    The desk where the Mac Pro is isn't where I typically use my laptop, so I carried the laptop over and plugged the monitor in, when that didn't work I looked online and checked here- I also returend the original adapter to the apple store. I inquired about it there, and the genius asked if my laptop was plugged in when I tried it out... sooo when I got home I tried it again with the new adapter and with the laptop plugged in, and it worked right off the bat with no trouble shooting or "detect display" necessary...
    The laptop must be plugged in for the external monitor to show up...
    now I know.

  • Mini DVI to DVI adapter not working for MacBook BlackRAM upgrade for MacBook black (Early / Mid 2008 model - MB404LL/A)

    Hello.
    I have recently purchased an external display monitor (LG D2342P LED) and I am trying to connect my MacBook black - MB404LL/A (Mac OS X 10.6.8, Core2Duo 2.4 GHz) to the LG LED monitor using mini DVI to DVI adapter. The dispay is getting detected by the macbook in the display preferences but the screen shows "No video input" ( as a blank-black that bahaves as no input coming to the Monitor).
    Please help, what should I do to connect to the monitor ?  Is there any setting that I am missing that needs to be preconfigured or is this an issue with software update of 10.6.8 ?
    Thanks in advance.

    Thanks for the reply, shldr2thewheel. I ll go ahead with the RAM specification you have mentioned.
    Can you please suggest about the Hard Drive, what should be the specification I should be looking for compatibility of my MacBook black ?

  • Mini-Display Adapter Not Working?

    Hello,
    Has anyone had issues with the Apple mini-display to Dual-Link adapter? Any problems getting it connected to the DVI cable (very tight fit) or have a dead on arrival adapter?
    I have a Mac Pro 6-core. I just received my 27-inch monitor and plugged it into the Mini-display port. I have two other monitors - Dell 21-inch monitors. One is hooked up to the DVI port on my Radeon HD 5870. The other was hooked up to the other mini-display port via the Apple Mini-display to Dual-Link DVI.
    When I try to connect the DVI cable to the Dual-Link DVI side of the adapter, it is a very tight fit. To get the screws to take hold, I have to press very firmly. Once secured, I plugged it in and the monitor is not recognized. Previously (before the 27-inch monitor came in) I used this very same monitor and DVI cable and it worked fine in the Radeon DVI slot. Still I swapped cables, switched mini-display ports, and switched the two Dell monitors around. And none of the pins on the cables are bent or damaged. It appears it is the mini-display to DVI adapter.
    I am in the military overseas, so to return it to Apple is a major event. So I want to be sure it is the adapter before i go to the trouble and expense of sending it back, having Apple send it to a family member, then have that family member send it to me (since Apple doesn't send items to FPO/APO addresses). Anyone else have any issues with the adapter?

  • Mini-DVI port not working: wear and tear?

    I had been happily using the mini-DVI port to play content on TV, using a DVI to Video adapter : plugging and unplugging probably twice a week.
    Now it seems to have stopped, abruptly: no signal at all is reaching the TV. (Adapter still works fine on my MacBook.)
    What are the chances of wear and tear damaging the DVI port? Is this a complicated fix? Any other thoughts? No recent upgrades or updates.
    "About this Mac" reckons it's mirroring fine, so it feels like a hardware thing. Many thanks in advance.

    Hello ewfelton
    It is very possible that the DVI port on the iMac has been damaged from wear and tear, as it's harder to get at than the MacBook.
    I would disconnect everything from the iMac, grab a clean towel and turn it face down on the desk. Then with a magnifying glass and light inspect the DVI port for a broken or bent pin. In the process of inspecting the port your SMC will also be reset, follow the instruction for "How to reset the System Management Controller" when your done.
    If the port seems OK and the SMC reset doesn't get it going use Disk Utility to Repair Disk Premissions and try it again.
    Your local Apple Store or local Apple Service Provider can replace a bad or damaged DVI port.

  • Mini DVI port not working on Macbook

    I often watch movies streaming on the internet by connecting my Macbook to my television via my Mini DVI to S-video adaptor cable.
    Last week, however, it suddenly stopped working. The television can still detect the display, but the image is super distorted and moving in a static-ey way. I can only vaguely make out the icons on my desktop on the TV screen.
    I thought that perhaps my adaptor cable was at fault, so I bought a new one - but the problem remains. I have also tried resetting the PRAM, repairing the disc and permissions with Disc Utility, and cleaning the Mini DVI port. I am pretty certain that it is a hardware problem with the port itself.
    One of the pins on my Mini DVI port looks like it could be out of place. It is kind of squished at the bottom of the port instead of laying flat like the others. I’m thinking that this might be the culprit. However, I have tried to straighten it out using a safety pin and I’m not really able to do it.
    Am I right to assume this is a hardware problem with my port? Any advice about how I might go about fixing this? Is there a way to repair the port without having to replace the whole logic board?
    The Macbook in question is a 2008 Core 2 Duo running Lion.
    Any suggestions at all would be much appreciated!

    Do not dismiss the possibility that the problem may be with the TV.  Based on what you have tried so far, an appointment at an Apple store genius bar is your best option.  The evaluation will be FREE and then you should be in a position to make an informed decision.
    Ciao.

  • Mini-DVI does not work with DVI anymore only VGA output

    Hi,
    I recently started to get problems with external LCDs. It used to work just fine, but now I can only use a mini-DVI-VGA adapter to get any output. This gives me much worse results than digital and makesme a little worried, other things might also stop s
    working.
    A quick search here and on google didn't give me any ideas how to fix this.
    So any help is much appreciated!
    Cheers
    GerHi

    Have you tried a new DVI adapter?

  • Airpot not connecting when mini dvi adapter is pluged in.

    Airport will not work when I hook up a display through the apple mini dvi adapter. When the adapter is unpluged I can connect to the internet. Does anyone know how to fix the problem. Thanks.

    Typically that is an indication the wireless connection is on the edge of reception and the added EMI from the display throws the connection off. What you want to experiment with is placement and proximity of devices. Move the wireless access point closer if possible. Move the display further away from the Mac if possible. Think about line of sight between the wireless access point and the Mac. Is the monitor sitting right in the middle between the two?
    You can also try changing channels that the wireless is working on. Sometimes that's enough.

  • Can't work with Macbook mini-dvi adapter to s-video out under Windows..??

    hi..
    My macbook can work well with mini-dvi adapter to tv out under mac os,but it can't work under windows os..
    If anyone's using their Macbook and has any comments please let me know..
    Thanks.
    Richard

    Yes, if you can get an s-video cable and plug that into the SCART adapter, that would be better than plugging in composite video.
    Clearly, having an SCART connection is not going to "improve" the video going in, you're going to be limited by the lowest quality connection. An s-video connection will provide a higher (but probably not a lot) quality signal than composite video.

  • G5 dvi to vga adapter not working

    DVI to VGA adapter not working with my G5 Dual 2.3 GHz Power PC. I am trying to use a VGA Monitor but can not get a signal. I also am using a Dell with a DVI Input and that works fine using a DVI Cable from my G5 to the Dell u2410.

    Bad adapter?
    The G5 ports are DVI-I. Any good DVI-I to VGA adapter should be fine.
