Using Mini DVI to VGA adapter on MacBook

I bought the adapter from Apple & hooked up my LCD monitor to the MacBook, but the video I get on the monitor is different that on my laptop. It has an old screen background & the dock but nothing on my desktop shows up. Also, when I'm plugged to the monitor, my dock disappears on the laptop screen. Is there some setting I need to change? It worked fine with my G4 PowerBook.
Thanks for any help....

i use the mini dvi-vga adapter in my classroom almost everyday. It sounds like your new monitor is running as a side by side monitor to your display instead of a "replacement" display.
To get your projector/monitor to basically show whatever is on your macbook screen once you've hooked up press F7....this should make your projector/monitory become your display with your dock & all of your desktop stuff. Your new monitor will completely mirror your display.
THis should do what you're looking for.

  • No video signal using mini dvi to vga adapter.

    I just bought a macmini,the last generation. Separately I bought on the apple store a mini dvi to vga adapter because when I bought the macmini I forgot to buy that....once the adapter arrived I tried to turno on the mini,everything seems to be normal,the mini works,the audio signal is normal and after the startup it asks me to choose the language,but the screen says there's no INPUT SIGNAL. I tried another mini dvi to vga adapter,the vga wire works with my pc so I didn't try another one,I tried the reset of the mini,nothing....do I have to try with "miniport to vga" adapter or is there something else I can try?

    I got my Mac Mini yesterday and I am having the exact same problem as you are having.
    I've tried on two different TV's but it is just not sending a signal. Is it faulty?

  • Using mini-DVI to VGA adapter to Samsung display

    I have 2009 late model of mac mini, The text on display looks washed out, not clear or sharp at all from day one, I thought it was the old model of monitor, tried the same cable to another monitor on another computer, SAME. so I thought the problem could be the cable or adapter.
    It's hard for me to believe is the signal from computer. I'm using VGA adapter made by Dynex bought from Best Buy.
    Anybody has suggestions?? Thanks

    Yeah, My old Samsung is lcd synmaster 17", bought many years ago at around $1000. Crazy, crazy price looked back. It's fine when I used it on the retired old Dell. It must be the adapter, trying not to buy another VGA adapter, could not image my next lcd will use one, anyway.
    This cable has only 14 pins vs 15 pins on the other cable, not sure if it matters?? Or if Safari has anything to do with it??
    Thank for you reply...

  • I have a MBPro mid 2013 with 1 Thunderbolt port. Just bought a Mac monitor and want to daisy chain a PC monitor to it. Use a Mini DVI to VGA adapter from MBP to PC monitor. How do I daisy chain the 2 monitors?

    Hall Palm Desert,
    if your Mac monitor has Thunderbolt ports, and the PC monitor is on the end of the daisy chain, then you might be able to do it by connecting your PC monitor’s VGA cable to a Mini DisplayPort-to-VGA adapter (e.g. Apple, NewerTech), connecting that cable’s Mini DisplayPort end to one of the Mac monitor’s Thunderbolt ports, and then connecting a Thunderbolt cable between the other port on the Mac monitor and your MacBook Pro.

  • Using external Display via Mini-DVI to VGA Adapter does'nt work

    Hey Guys,
    i recently bought a mini-dvi-to-vga adapter.
    When I plug it into my macbook and connect it to my 19" external TFT, the MB recognizes the TFT as [Medion] MD30219PH but the display stays blank (no matter if i choose mirroring mode or extended desktop)...
    Already changed the Hz-Rate between 59.9, 60 and 75 Hertz and the Resolution also... but nothing happens.
    In extended Desktop mode i can even slide the cursor into the area where the display is supposed to be...
    Hope u can help me
    thx

    From what I've been told, using the computer's video output isn't outputting a true NTSC picture. I was told when talking about how the Macbook Pros dropped the S-vdieo port that I shouldn't use that anyways, but rather to go the firewire route. THat was actually converts the video source to true NTSC instead of taking a computer output to a TV. While I have no doubt that it works, I'm willing to bet that you'll see a noticeable difference between the G5 S-video and your MB using firewire. Most consumer camcorders from the past several years do digital (firewire) to analogue (NTSC) conversion, so you probably don't even need a new box.

  • Apple Mini DVI to VGA Adapter

    I purchased a Apple Mini DVI to VGA Adapter for my MacBook (early 2008).
    When I plug the cable into my MacBook it works fine, I have to drag the browser from my macBook onto my LCD using the curser. But when I do this with iTunes and I want to watch a film or music video there is no sound. Does anyone have any ideas of how to solve this problem or if im using it right.
    Please help.

    Ah. Okay. Well you need to output the sound from your MacBook to your TV. You need another cable to carry the audio. You can use an 1/8 mini audio to TOSLINK (if your TV supports optical audio input) or 1/8" to RCA audio (those red/white cables).

  • Mini DVI to VGA Adapter Issues

    Hey guys,
    My first ever post to the forums. I just recently bought my very first apple computer. It is a 2.4 ghz Macbook 13" and bought a Mini DVI to VGA Adapter so that I can connect it to my 46" Sharp AQUOS TV. I connect my laptop with the dvi to vga adapter plus another vga cable of course and all I get on the screen is my wallpaper but I can't see any of the icons on my tv screen, nothing.
    Can anyone help me on this? Does this sound like a familiar problem?
    I would appreciate your help.
    Thanks in advance,
    Dogan

    Hi DoDolom,
    First, welcome to Macintosh!
    Secondly, it sounds to me like what's happened is that OS X has extended your desktop onto a second monitor. Plug in an external mouse and keyboard and then close the MacBook's lid. It will go to sleep. Use the external mouse/keyboard to wake it up and you should be running on just the external display.

  • Mini- DVI to VGA adapter Or is that, DVI to DVI?

    I am having difficulty figuring out which adapter to purchase if I want to use my MacBook to make a Keynote or PowerPoint Presentation with an LCD projector.
    Do I need the Mini- DVI to VGA adapter, or is it DVI to Video adapter, or DVI to DVI adapter? Good grief! I've made fabulous-looking slides and just want to take my computer to the lecture hall, connect it to their projector, and give my talk. How does one decide which cable to get, if I don't know for certain what kind of projector they are using?
    Aren't all LCD projectors standardized this way?
    Thanks for the clarification.
    ~ john

    As mentioned, VGA is much more common than DVI is on projectors, so the mini-DVI to VGA will certainly work more often than the mini-DVI to DVI will.
    It costs $19USD, so I would get both and use the best option available to you when you get to the location and see what kind of projector they have.
    You also may want to pack the VGA and a DVI cable just in case. You never know if the location will have one on hand, or if it gets misplaced just in time for your arrival.

  • Mini DVI to VGA Adapter w/ extension cable

    I would like to get a Mini DVI to VGA Adapter for my macbook. Does anyone know how it would would if I used it with a VGA extension cable. Any experience will be helpful

    Depends on how long the cable is, and if it was of sufficient quality for computer use. The higher resolutions require better quality and shorter cables. You may get some signal loss for long cables. A standard monitor cable that comes with a computer monitor should be fine, but what kind of length extension cable are you talking about?

  • Apple Mini-DVI to VGA Adapter Problems in Boot Camp / Windows

    I currently run Windows XP SP2 on my MacBook and recently purchased the Mini-DVI to VGA adapter so I could hook up the MacBook to an external projector, monitor, or TV to display what's on my Windows screen on the external device. However, when I connect it to any external device, it just goes nuts and sporadically continues to make the hardware connect and hardware disconnect sounds and doesn't allow for external output of the screen. Any suggestions...? Thanks!
    Marc

    I think I solved this problem.
    It was in issue for me. My second monitor would only display the Windows XP screen when it was loading, then it would black out. I couldn't even move my mouse arrow to the other side. Then I fixed it, here's how (running Windows XP SP3):
    1. Start > Control Panel > Appearance and Themes
    2. Display
    3. Go to tab "settings"
    4. Double click the blue image with the "2" inside it. This is the second monitor, adjacent to your first, or primary, monitor. The blue box may be a desaturated, greyish blue, meaning that the monitor is disabled. Click it and it a box will pop up asking if you want to enable the monitor. Click OK, and then like magic, your monitor is resurected in it's Windows Glory! From there, adjust the resolution, and it should work perfectly.
    This isn't a Boot Camp compatability issue, it's just a problem with the lack of familiarity that users of OS X have with using XP.
    Have a nice day!

  • Apple Mini-DVI to VGA Adapter Resolution?

    If I hook my macbook to my hdtv using the Apple Mini-DVI to VGA Adapter what's the highest resolution I'll achieve? Will it be the max resolution of the TV or the Macbook?

    Hey,
    These are the specs that Apple provides for the GMA 950.
    "Extended desktop and video mirroring: Simultaneously supports full native resolution on the built-in display and up to 1920 by 1200 pixels on an external display, both at millions of colors."

  • Mini-DVI to VGA adapter length

    I'll be officially switching from microsoft to mac this month and i cant wait.
    after much thought as to whether i should buy a MBP or a MB i decided to go MB
    I plan to use my MB as a desktop while im in my dorm. I already have a 17 inch HP LCD monitor that works perfectly fine
    I know that in order to hook the monitor and the MB up i need to get the mini-DVI to VGA adapter.
    My question is, how long is the actual cable for the adapter? The picture on the website looks kinda short and I don't know whether or not the cable will reach from the back of the monitor to macbook. Will the cable be long enough so my macbook can rest freely on my desk, a few inches in front of my monitor, or am I going to have to put the monitor on top of/in front of my macbook.
    Thanks!
    ~Dan

    The cable on the adapter is only 2.5 inches long.
    I wish that Apple would make a mini-DVI extension cable so I could get the big bulky adapter off of my desk.

  • Mini dvi to VGA adapter to HDMI cable

    i have a mini dvi to vga adapter for my macbook (bought in 2007) and that works but I want to connect to hdmi cable to this? But don't exactly know how to do this or if it is possible?

    It is my understanding that 'VGA' is analog and HDMI is digital....from what I have read it won't work without a convert
    I use a Mini DVI to DVI adapter and then a DVI to HDMI adapter to run the HDMI cable to to TV
    the converter...VGA to HDMI...

    Personally I would shelf the VGA adapter and go with the new cable set up...if you already have the HDMI cable then an adapter from DVI to HDMI would be in order

  • Mini DVI to VGA Adapter M9320G/A on late09 mini

  • Mini DVI to VGA Adapter Video Problem

    This year at Randolph-Macon College we replaced the Math lab Emac computers with IMac G5 Intel machines. The laboratory has an NEC model MT1050 projector with a manufacturer’s date of August 2002. We can not seem to get rid of ever present scan lines. We can slow them down and speed them up by adjusting resolution and refresh rates, but nothing will remove them. We are connecting the IMac to the projector via the Apple Mini-DVI to VGA Adapter. It is specifically designed for use with the iMac (Intel Core Duo), and the adapter connects to the Mini-DVI port of the computer and the VGA end of the adapter to an external VGA monitor or projector.
    Troubleshooting the problem we have swapped IMac Intel computers with no luck, but we still have to use the Apple Mini-DVI to VGA Adapter. When we hook the projector to a Intel Mac Book Pro, we have to use a different adapter, but then it works perfectly. In fact, everything we try using other adapters works fine, it’s just when we use the Apple Mini-DVI to VGA Adapter that we experience the video problem.
    Has anyone experienced this problem and if so, have you been able to remedy it?
    iMac (Intel Core Duo)   Mac OS X (10.4.8)  

    I don't have much to suggest, except to ask if you can try with a different mini-DVI to VGA adapter. (i.e. do you have more than one on hand to make sure yours isn't just defective?) Make sure it is firmly seated into the iMac.
    I use the same adapter to provide an extended desktop on an old CRT monitor and the display is great.
