Does dvi to vga adapter change resolution

I had this hooked up to my tv and watched video from had drive. I shut down computer one evening, the next day turned i on, and picture is blurred, and can't see anything---maybe a resolution problem but can't see to change it. bought a new adapter, same thing. I hooked up to another tv, without vga adapter and seems to be fine, hookeed back up to tv with vga adapter, still no picture.

Hello,
Safe Boot from the HD, (holding Shift key down at bootup), see if you can set a good rez there.

  • 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 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."

    A DVI to VGA adapter provides a conversion from DVI to VGA.
    A DVI to DVI adapter, what is that? If the input is DVI and the output is DVI, what is the need for an adapter?
    Tell us what you are trying to accomplish.

  • I am considering a Apple iMac but would be interested in adding a second monitor. Does it have to be an Apple monitor or can i add any monitor with a thunderbolt cable and DVI or vGA adapter?

    I found that the Thunderbolt input accepts the mini-DVI (in my case converter to VGA for a tutorial use monitor)
    BUT, you have to really oush it in 'til it clicks.  I thought it too loose until I tried it.  works just fine!!
    i get a solved for my own  LOL

  • Dvi to video adapter changes shape

    When I plug my DVI to Video adapter into my macbook pro, all of the displays change shape, and no matter what resolution I choose, it won't go back to it's true size.   When I try a DVI to vga adapter, it works fine.

    Try starting the Mac in Safe mode.
    http://support.apple.com/kb/HT1455
    Hopefully that will result in a usable screen. If it does, go into Displays Preferences and change the resolution to what it was when you had things working properly before. Then restart normally and the resolution selection made under Safe mode should persist through the normal restart.

  • 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

    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 doesn't fit Mac Book port

    I bought a "mini dvi to vga" adapter at the local Apple store at the mall and it does not fit the mini DVI connection on my Mac Book. What is the correct mini dvi configuration or part number for the Mac Book Mini dvi port?

    It may be. I threw the bag out so I can't check. I was in a hurry and thought I picked up the right adapter but guess not.
    Thanks for your help. Know anyone that needs a mini vga to vga adapter?

  • 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.

  • 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!

  • DVI to VGA Adapter Closed Lid Mode Distorted Picture on TV

    Hi
    I managed to hook up the DVI to VGA adapter and view on my Sanyo TV. Nothing fancy just a older TV.
    I am feeding through the Yellow Video output into the video input on the TV. (Also tried s-video)
    Viewing with the macbook lid open no problems. Remembered that I could close the lid.
    Followed the instructions online about connecting, closing the lid and waking up using my bluetooth mouse.
    First time things went well - able to use Front Row and View Slideshows etc. also steaming video from Safari, (TV Land for my kid)
    Then the screen began to flash - and change to black with rolling images.
    Like you used to have in the 60-70's black and white TV - multiple images rolling past over and over.
    I tried rebooting - starting new connections, using different cables, using both VGA and S-Video directly into the TV and not through my reciever.
    Any ideas!
    I can't use closed lid mode at all. I must instead, dim my screen.
    Help?
    Thanks
    Buddy

    Thanks, BSteely, I have the latest QT and iTunes already. Closing the lid seems to kick the MacBook external display into some special mode that Front Row can't display videos in. For example, you get the Front Row interface, but as you select movies/TV shows, the preview window on the left side is blank. Open the cover, and have both displays going, and you can see the previews fine (and of course, you can see the movies/TV shows play fine as well when you click on them)
    Running Quicktime Player full screen works fine without Front Row in either open or closed lid mode. So it is apparently something wrong with Front Row itself.

  • Dvi to vga adapter?

    I want to connect a 20" VGA monitor to my Powermac dual 2.7. I looked in the Apple store and here's what they had:
    "The Apple DVI to VGA display adapter was specially designed to allow users to connect their DVI equipped PowerBook G4 or Power Mac G4 to an external VGA monitor or projector for 24-bit video-mirroring or dual display.. The DVI to VGA adapter plugs into the DVI port built into the new PowerBook G4 or into Power Mac G4s with NVIDIA or ATI Radeon graphic cards which feature DVI ports"
    Does Apple make an adapter for a G5 Powermac, if not, any suggestions on which one and where to get one?
    Thanks, Pete

    Yeah, I think you're working too hard.
    That one should be fine. I think you can only use one of them, as they're too wide to use one on each of the video card's ports. That's how it is on mine. Only an issue of course if you decide to use two VGA monitors.

  • 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.
