VGA out to Mini Displayport in: possible?

I'd like to use my 27" i5 iMac as an external display for my crusty work laptop (Dell Latitude D630).
The only video out on the laptop is a VGA port - no DVI, no DisplayPort.
Does such a creature as a VGA->DisplayPort adapter exist? Will I be able to drive the full resolution from my laptop? (it has a 128MB nVidia Quadro 135NVS video card)

Hi Peter,
such 'creatures' might exist (I am not aware of one...) but it would be a lot more than a simple adapter since it would have to take the analog video signals from VGA and convert them to digital video signals for the Mini DisplayPort.
So, most likely such thing would cost in the range of 300USD !
And even then, the quality of the converted signal might not be up to the quality you now have with the iMac display.
Regards
Stefan

  • My VGA output using Mini DisplayPort to VGA doesn't work.

    Since I upgraded to Mavericks, my VGA output using Mini DisplayPort to VGA doesn't work. When I was using Mountain Lion, as soon as you plugged in the Mini adaopter into the mini display port, the screen would shrink and format to where it would project via a RGB cable to a projector. No such luck since Mavericks! Also, I had a lot of trouble with the DVD player when I tried to play a DVD and project it via a projector. It all worked seamlessly with Mountain Lion. Can anyone help me?

    I think if you go to System Preferences >> Displays and Option-click on the "Scaled" radio button, it will show you all of the resolutions that you would have had before under Mountain Lion. I just upgraded to Maverick and my resolution preferences (mirrored on a TV using the Mini DisplayPort to VGA adapter, using 1280x768) were completely reset (my display was no longer mirrored, and the resolution on my main iMac screen became 2560x1440). I found my answer here: https://discussions.apple.com/message/23599645#23599645. Hope that helps.

  • Connecting a vga monitor to mini displayport with 2 adapters

    Hi. I have a 21.5 inch iMac and I want to attach a second monitor. The monitor that I bought, the MultiSync LCD1560m, says it is mac compatible. it has two inputs; one DVI-D and one VGA. The monitor came with a vga cable, but not a DVI-D cable. I bought a dvi to mini displayport adapter, thinking the monitor would come with a DVI-D cable. I also had a VGA to DVI cable laying around, and attached that to the other adapter. The iMac won't detect the monitor. The chain from the iMac to the monitor is as follows: Mini DisplayPort > DVI > VGA. I don't want to shell out $40 for a new DVI-D cable. I've already rebooted multiple times plugging and unplugging the mnitor in before and after the iMac started up. I've also reset the PRAM. Does anybody have a solution that doesn't involve spending (much) money? (I'm broke. my monitor only cost $75). Thanks.

    $40 for a DVI cable, where are you shopping Macy's?

  • Fake Apple Macbook Pro Air VGA-Adapter for mini DisplayPort

    Hello everybody,
    in November 2009 I ordered a VGA-Adapter for my MacBook Pro at Amazon.de. I used it occasionally over the last year. But today it didn't show anything before a presentation. I went to a local Apple service provider and he said it's a fake one. I didn't see another one the last year, but he's right. I made some pictures you can see here:
    http://www.abload.de/img/img_09276ay7.jpg
    http://www.abload.de/img/img_09283len.jpg
    I'm not sure but I thought I would get an official one when I bought this. I checked my feedback at Amazon (because it's from a third party seller) and I mentioned that I was wondering why the adapter was in an official DVI for mini DisplayPort packaging. It was 10€ cheaper than the regular one. Not too much to think it's not official.
    It's way over warranty time, but I'm ****** it's not working after using it only 10 times over the year (just for presentations). What can I do after buying a fake one? Go back to the seller or not?

    Going back to the seller would be your only recourse, although Amazon might be able to assist if the seller advertised the adapter as a genuine Apple part and sold you a fake instead. After this much time, though, there's probably nothing Amazon can do, and it's doubtful the seller will do anything either since the adapter apparently worked without problem for over a year. Even if the part were genuine Apple it would be out of any warranty at this point.
    Time to just buy a new adapter, it would seem, if you haven't already.
    Regards.

  • No audio out through Mini Displayport?

    Last night I hooked up my first-gen MBA to my plasma TV using a connector that converted the Mini Displayport to HDMI. The movie I streamed from Netflix looked great. One problem -- no audio. I guess there's no audio out through the Mini Displayport? I was forced to hook up computer speakers to my MBA. Is there a way I can get audio to go through the Mini Displayport rather than the audio-out/headphone jack?

    There are a couple of adapters out that will convert DVI plus optical audio to HDMI (with audio). They are all made by the same company (though they are branded and priced differently). I think they are currently running around $100. The problem you might run into is HDCP. Apple doesn't do HDCP with their DVI... so you'll end up not having a compliant HDCP chain... if that is important to you.
    If you do this setup, make sure you have your TV set to a setting that is pixel to pixel... that is, doesn't adjust for overscan. Lest you loose some of your computer desktop.

  • Feb 2009 MBP-Audio out thru mini displayport?

    Does my MBP, bought new in February 2009 (Build 10F569) support audio OUT on the mini displayport?

    No. That was introduced with the April 2010 models.

  • I cannot get both monitors to work when connecting my MacBook Pro to a VGA monitor using Mini DisplayPort to VGA Adapter

    Need help with 2 monitor set up on MacBook Pro.

    I am sorry for the confusion.  The reason I asked about the speaker bar is that I can't find any information that shows built-in speakers on your monitor.  I have looked everywhere, including in the HP specifications.
    Here is the Back I/O panel (Input / Output) for your computer:
    Figure 2: Back I/O panel
    1 - Video Graphics Adapter port
    2 - USB 2.0: 4
    3 - RJ45 Network (LAN)
    4 - Audio: Line in
    5 - Audio: Front speaker/Line out
    6 - Audio: Microphone in
    The way that I have always connected speakers is to the port labeled # 5 (Audio: Front speaker/Line Out).  This port allows sound to be sent to speakers.  The VGA port is for video only.  There is no audio capability.  The only connection that sends Audio and Video is the HDMI (High-Definition Multimedia Interface) connectors.
    This is the type of connector that I would expect to see coming from your speakers:
    The male one at the bottom of the picture.
    Please check the monitor carefully to assure that there are actually speakers built-in.  I just don't want us to continue fighting a problem that doesn't exist.  There may have been some incorrect information in the advertisement that you read.

  • What is the difference between Mini DVI to VGA adapter and Mini DisplayPort to VGA Adapter?

    ......your MacBook has the Mini-DVI port........the VGA end of the adapter is the same on both...

  • Mini DisplayPort to VGA Adaptor : Gateway Monitor FPD1760 - Compatible ?

    Hi. Is the Apple, Mini DisplayPort to VGA Adaptor compatible with Gateway Monitors?, I own a Gateway FPD1760 (Specs : http://www.dealtime.com/xPF-Gateway-Gateway-Monitor-FPD1760).
    Just wanted to know if I should be going with Mini DisplayPort to VGA Adaptor or) Mini DisplayPort to DVI adapter, as I have heard too many complaints about the former.
    Thanks in advance

    If your monitor has DVI input, get the DVI adapter. DisplayPort is digital, DVI is digital, but VGA is analog - the signal conversion will result in a (slight) drop in quality.

  • MBP Unibody and Mini DisplayPort to S-video adapter

    Why is the Mini DisplayPort-to-s-Video Adapter the only adapter that Apple can't seem to make? My late model PowerBook G4 came with its own S-Video out, which was perfect for running video to the dual overhead projectors in my Sunday School class. But alas, the PowerBook couldn't keep up with the multimedia video requirements I made for it, so I upgraded to the MacBook Pro (mid 2009). But I can't find a friggin' adapter to save my life! I've tried an external VGA unit, only to have the video rolls all over the screen with no way to stop it. All I need is one simple adapter: a Mini DisplayPort to S-Video /Composite adapter. Apple makes almost the exact same adapter, but it's for the mini-DVI out. At least the PowerBook had a full-size DVI out- all the MBP has is the single, stupid Mini DisplayPort. Why can't the fine folks at Apple make up their stupid minds which ports they're going to use?

    This is why I think that won't work. I might be wrong tho.
    Once you head on over to VGA from the Mini DisplayPort, you are then talking about an ANALOG signal. This analog signal must be changed BACK to digital in order to work with S video. So, what you need is a VGA to S video converter box. They are a lil too pricey for me, around $100 I think.
    What I was thinking was this. Since Mini DisplayPort and S video are both digital signals, you need to have digital all the way. I wonder if the Apple Mini DisplayPort to DVI Adapter shown here:
    http://store.apple.com/us/product/MB570Z/A
    would work when connected to the DVI to Video Adapter shown here:
    http://store.apple.com/us/product/M9267G/A?fnode=MTY1NDA3Ng&mco=MTA4NDU1Mjc
    At that point you would need an S video cable connected to the second adapter...but if the first adapter is in fact transmitting a digital signal, the second adapter should then just pass through that digital signal to the S video cable.
    Has anyone tried this?

  • MBP 2009: Audio over Mini DisplayPort

    Hello
    I previously ordered a Mini DisplayPort -> HDMI cable (http://www.amazon.co.uk/1-8m-DisplayPort-Adapter-Unibody-MacBook/dp/B003WVC8R2/r ef=sr1_fkmr01?ie=UTF8&m=A1T39SA8AUFT6J&qid=1289477962&sr=1-1-fkmr0).
    It's been working great with my 2009 model MacBook Pro, however I have to use a separate cable for audio.
    When in the Apple Store recently to fix a battery problem on that laptop, I got into a discussion about audio through HDMI on this model. According to the Mac Genius audio through Mini DisplayPort was enabled on older devices through a firmware update (and he said his Mac Mini now uses one cable to do audio and video).
    Audio is not working with the cable above - but was I incorrectly informed by Mac Genius, or do I need a different cable that does support audio?
    Thanks
    Jamie

    All we know about your MacBook Pro model is that you've identified it as a "2009 model MacBook Pro." Apple introduced audio-out via mini-displayport in the April 2010 MBP models, so if yours was bought before then, it didn't have that capability when it was new. To the best of my knowledge and belief, nothing that has happened or been released since then has changed that.
    [This article|http://support.apple.com/kb/HT4241], updated in June 2010 (after the release of the latest mac Mini), lists the Mac models that supported audio via mini-Displayport at that time:
    "iMac (Late 2009), MacBook Pro (Mid 2010), MacBook (Mid 2010), and Mac mini (Mid 2010) supply multichannel audio (up to 8 channels) and video signals over Mini DisplayPort."
    I haven't heard of any update that has changed that list since then. If it were possible to enable audio output by means of a firmware update, I think Apple would have made that update available to all owners of mini-Displayport-equipped Macs, not just some of them.

  • Have a 2008 iMac 24".  How to convert from mini-DVI to mini-displayport?

    I bought this awesome device recently:
    http://www.monoprice.com/products/product.asp?cid=104&cp_id=10428&cs_id=1042802&pid=6331&seq=1&format=2
    It takes the TOSLINK audio output and the minidisplayport output and combines it into HDMI to use in a home theater. However, I just found out that older iMacs (2008) have mini-DVI out, NOT mini-displayport. I've searched high and low and I cannot find a cable/adapter combination that will convert this for me so I can use it on my 2008 iMac. Any suggestions?
    IDEALLY it would be a male mini-dvi to female mini-displayport. This doesn't seem to exist.

    Well, there is this one
    http://www.atlona.com/Atlona-DVI-to-Mini-DisplayPort-Converter-p-17859.html
    but it is expensive. Going from DVI to DisplayPort is not simply a matter of changing the shape of the connector. And you would need a Mini-DVI to DVI adapter to connect to this device.

  • Mini DisplayPort to DVI Adapter failure misdiagnosed

    When I purchased my new MacBook Pro last December, I had to purchase Apple's Mini DisplayPort to DVI Adapter in order to continue using my Apple 20" Display monitor with it.
    Turns out the Mini DisplayPort to DVI Adapter dies so I no longer had access to use of my Apple 20" Display monitor
    Only the cause of the display's going blank was not clear
    I took my MacBook Pro and the 20" monitor tothe apple store Genius bar.
    Using my computer and my 20" monitor, the Genius tried making it work with my bower block and with another one in the store. Nothing worked.
    What he didn't test was the Mini DisplayPort to DVI Adapter itself to see if that was the problem.
    So I bought a new monitor and that didn't work either.
    I had to go back to the Apple store Genius bar a second time for them to figure out that it was the Mini DisplayPort to DVI Adapter.
    Big PITA (Pain in the A..)
    Poor diagnosis the first time gave me 10 days of frustration.
    What's with that, Apple?
    Steve

    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.

  • Does Mini DisplayPort to DVI adapter output sound?

    I am using the Mini DisplayPort to DVI adapter, like this one:
    with my Macbook Pro 17-inch, Mid 2010.
    I also happen to have a DVI to HDMI cable that I tried to connect to my Samsung LED TV (2014 yr.)
    The picture that I get on TV from the screen mirroring from the Mac is great but I don't have any sound. So I'm curious if DVI could be killing the sound in this case? Any ideas?

    I don't think the DVI standard carries sound, so while Mini DisplayPort can handle audio, DVI probably won't carry it any further.
    Does your TV have an unused HDMI port? MacBook Pros after a certain version do send audio out of Mini DisplayPort and the audio can be carried through HDMI to a TV or receiver. HDMI would be preferred over DVI for this reason, unless your MacBook Pro is too old. If it is, then with either type of connection you would need a separate audio cable connecting the audio-out on the MacBook Pro to an audio-in on the TV.

  • Mini displayport hdcp

    I've got an LG L204WT screen connected via VGA cable to mini Displayport. I've also connected to a sony Bravia TV.
    I purchased an HD movie in itunes, and cannot watch it on either screen because of the hdcp.
    I know the master key has been released, is there any info on how to use it/run a keygen, so I can watch my movies?

    Don't know if you have resolved this but, for what it's worth....here's my setup:
    MacPro (2009)
    ATI 4870HD
    LG GGW H20L BluRay Writer
    HP DreamColor 2480zx
    Win7 64bit Ultimate
    Cyberlink Power DVD Ultra
    From the ATI card to the HP monitor, I have a MDP to Full Size DP; works perfectly. I have also utilized a MDP to a full size HDMI cable and that works perfectly as well.
    Don't know why you are using MDP-DVI-DVI-HDMI. Simplify....you only need one cable.
