Mini dvi to vga to projector help

Having a serious issue with the mini dvi connector. It is plugged into the projector, everything is working fine. The mac is not able to discover the new display. It works fine on windows computers, but refuses to work on a mac.
Is there anyway of changing the settings or resolution so that the display can be found?

I'm seeing the same thing on my macbook running as a closed clamshell connected to an external keyboard/mouse/monitor. It boots OK but if it falls asleep I'm in trouble. The external keyboard/mouse will wake it, but only for a few seconds before it falls asleep again. The only way to get it awake is to open the MacBook and use it as a secondary monitor. Kind of irritating since I use the macbook in this configuration often. I've also set sleep on power adapter to "never" to try to avoid the problem, but the system doesn't seem to be honoring that setting.
I'm guessing this might be related to the "extensive graphics updates" in 10.5.5, as I've only really seen the issue crop up since 10.5.5.

  • Mini Dvi to VGA for Projector issue

    I recently bought a mini DVI to VGA adapter for my new macbook Black 2.4 ghz. When I hook this up to the projector nothing comes through, but the computer recognizes the projector. I know it is not the projector because when I plug in my 12inch powerbook it instantly recognizes the computer and displays whatever is on the screen. I even returned the adapter for a new one and am still having the problem. Is there something I'm doing wrong? Are there steps that I'm not doing, or is there something wrong with the mini dvi on my macbook?

    When I attach my MacBook to a projector via mini DVI, all variations of order of activation used, the desktop image appears, but the icons and other open pages are off the screen to the right.
    Of greater importance, Keynote presentations appear as two slides side by side, with a timer under the left image and no transitions.
    This has happened with two portable projectors and one overhead, exactly the same images with each.

  • Samsung P400 Projector not working with mini-DVI to VGA

    I've never had so many hardware problems with a computer before... sigh.
    Why they labeled a 100-240v 50/60Hz power supply with a sticker that says 100-120V 60Hz is beyond me (Sony did the same with their original US PS3s but that's another tale). Anyways, here's my issue.
    I just bought the new 2009 Mac Mini along with a Samsung P400 Projector. This is one of those new pocket type with the LED bulbs.
    The Samsung P400 has a native resolution of 800x600 60Hz and can accept analog composite or VGA video signals.
    So, in my blind belief that Apple would sell me the correct adapter to go from mini-DVI to VGA, I went and I purchased said adapter. And lo and behold, it doesn't work.
    Now, I'm a computer guy, I've built my own systems. I know the difference between analog and digital, DVI-I and DVI-D, etc. So, when I read the specs on my merchandise and they all use the same connection labels DVI, mini-DVI, VGA, etc. it really irks me to find that they are all incompatible with each other. I don't understand how this is supposed to help the customer. It's ridiculous. Apple is supposed to be user friendly but this is downright evil.
    But, I've invested over a thousand dollars in this venture and I want it to work. *SO, before I go and run out and spend another $30 on a mini-DisplayPort to VGA adapter, can anyone tell me if it will work with my projector????*

    Thanks for your help.
    But I had just figured out a solution today. I guessed that the resolution wasn't holding when I switched monitors so I went and picked up a mini-DisplayPort adapter to run the monitor along side the projector at the same. This way I could see what was going on.
    Turns out that projector was automatically being set to 1600x1200. I changed the resolution to a lower one and it was fixed. Of course, when I tried to switch back to the mini-DVI to VGA adapter, OS X forgot the settings again and I had to redo everything.
    I'll try your solution as well but for now, I think I am okay. I will just use the mini-DisplayPort to VGA and not unplug the projector unless I really have to.
    I'll test your solution just in case I need to reset the resolution again.
    Thanks once again!!!

  • Help! Syncmaster 1100 blurry when connected to Imac with Mini DVI to Vga

    Hi,
    I recently tried to use my Samsung SyncMaster 1100 (21") as a secondary display But when I connect it with the mini dvi to vga adapter to my imac the image looks blurry. Is there some compatibility isue with syncmaster 1100?
    Please Help!, I tryed the imac with a different secondary monitor and it works fine. I tested my syncmaster with another pc and it works fine. I don't know what else to do.
    Thanks in advance

    Hi Josh,
    To start, it is considered extremely impolite to type in all capital letters as you have done. Please use all lower case, or preferably properly capitalised text, in future.
    With regards to the problem you're having.. the reason you only see the desktop background is due to screen spanning. If you want the external display to display the same thing as the internal display, go to the displays system preferences pane, and check the box that says "Mirroring"
    The color problem is probably due to a loose connection somewhere, either between the iMac and its adaptor, the adaptor and the cable to the projector, or between the projector and the cable plugging into it. If you're still having problems, try different adaptor cables, or try plugging it into a different monitor to try to work out which one is causing a problem.
    Good luck

  • Mini DVI to VGA cable doesn't send signal to the projector

    I just received a mini DVI to VGA adapter cable today.
    I connect mini DVI side of cable into my Macbook v. 4.1 and connect the other side into DGA cable, which connected to LCD projector.
    When I connect the cable to my Macbook, the opened application streched out to a full screen (seems like computer detets the cable) but projector says 'no signal'.
    Can any one tell me what is wrong it is?
    Thanks much
    Mike

    I'm still stucked.
    By reading some articles, it says even using mini DVI adapter, the signal is still digital and if the projector doesn't accept digital signal then it's no use....
    My projector is Epson EX3200 and it doesn't have any DVI or HDMI input.
    Does this mean my projector doesn't accept a digital signal?
    But, but, but if even uing mini DVI adapter cable it still doesn't conver to analog signal then why they call the cable a mini DVI to VGA cable???
    Why should this world be so complecated.....

  • Mini DVi to VGA :  impossible to display to a video projector

    hello !!!
    I bought a MINI DVI to VGA adaptor and i as soon as i connect my videoprojector (Sanyo) to my Imac with the mini DVI-VGA adaptor, my Imac screen freezes and nothing appears on the video projector screen.
    What can I do ?
    Thanks

    Not exactly, though you can reset the PMU of an iMac flat panel machine with a PowerPC G4 processor, reset the SMU of a G5 PowerPC-equipped platform, or reset the SMC of one driven by an intel processor.
    Any corrupted settings stored which might affect your external video will be dealt with by those processes. Have you attached the adapter alone and seen this same outcome, or does it occur only when a VGA projector is attached to the adapter?

  • Mini DVI to VGA Connector

    Hi I am trying to connect my Macbook to a projector via the Mini DVI to VGA Adapter. My Macbook recognizes the projector in the system preferences but the projector says no signal. I have tried every kind of arrangement, of computer on first, or projector on first and have had no luck. Then I tried connecting the same Mini DVI to VGA to my hp Monitor at home and that works just fine.
    Can anybody give any ideas as to how to fix this? I have had to use my wife's crappy PC 2 weeks in a row to run my Power Point in my class. I need help!

    I tried all the resolutions that I had available. I tried different combinations or resolutions with different Hz rates. I also tried putting them both on the same resolution with the same Hz. I also clicked detect displays and nothing happens. When I first plug the projector into my Mini DVI port the projector resolution and Hz, and the LCD resolution and Hz automatically change to the same.
    And what kinda weird is that my assistant professor in the class has an old G4 Powerbook and he can connect up to the same projector instantly. Is there any way of posting a pic, because I took a screen capture showing what my comp. looks like when i plug it in?

  • Mini DVi to VGA colour issues

    Hi,
    I recently purchased a projector to connect to my macbook. My intension was to use a mini-dvi to vga cable to do this, however when i connected everything up the projected image had a green tint. I must also state that i have connected a TV to the same port with a mini-dvi to s-video adaptor with no problems with the colour.
    My first thought was that the cable was the problem, so i borrowed my friends macbook to see if they had the same problem. There where no issues, so if figured it was either a software or hardware issue.
    My next step was to boot off the start up disk and plug the projector in, same issue - green tint.
    So i have concluded that it is a hardware issue. I know that the mini-dvi port is connected directly to the logic board, if i want to get this fixed will i have to replace the whole logic board or is there another way.
    All your help comes much appreciated.
    Thanks in advance

    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.

  • Problems after trying mini dvi-to-vga

    I plugged in my mini DVI-to-VGA and it worked for a minute. Then I bumped the adapter out of my MacBook and now it does not work. I can get an image on my tv, but it's only of my wallpaper, no matter what I'm viewing.
    The bigger problem I have is that my MacBook screen is now magnified. I've tried playing with the display settings, and have confirmed that my zoom is turned off. Now that I think about it, I'm thinking this was caused by viewing a Netflix streaming movie on full screen. Maybe?
    I don't know if these two issues are related or not but they started at exactly the same time. Help?

    Hi Robert, I cannot answer for you, as I have the same problem, which only came to light yesterday. 
    The same problem is discussed in the MacBook Pro community and none of the solutions there has solved the problem for me.  Maybe one of them will for you.  The link to this other set of problems is:

  • 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,

  • 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.

    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!

  • Mini-DVI to VGA maximum resolution?

    I have an external monitor with only VGA input, and it's resolution is 1680 x 1050. Will my MacBook be capable of using this display at it's native resolution using a mini-DVI to VGA adapter?
    The display is the HP w2007v in case anyone is interested.
    Thanks

    Hi Josh,
    taken from Apple Video Developer Note found here:
    http://developer.apple.com/documentation/Hardware/Conceptual/HWTechVideo/Articles/Video_implementation.html#//apple_ref/doc/uid/TP40003994-SW741200331181
    External Display Modes
    The default display mode setting on the MacBook is extended desktop display. To toggle between the two modes, press the F7 key, or go to System Preferences>Displays>Arrangement.
    A scaling function is available when the internal display and an external monitor are both operating and the mirror mode is selected. However, the external monitor could have black borders during mirroring, depending on the supported timings between the two displays and on the monitor’s selection algorithm. Black borders are not seen on VGA displays.
    Both displays show full-sized images when the display resolution for the external monitor is set to the internal display’s native resolution: 1280 by 800. Both displays can operate with other resolution settings, but in mirror mode, one of the displays may be smaller than the full screen and have a black border around it. With the resolution for the external monitor set to less than 1280 by 800, the image on the internal display is smaller than its screen. For resolution settings larger than 1280 by 800, the image on the external monitor is smaller than its screen.
    In mirror mode, the maximum size of the external display is 1280 by 800 at 60 Hz. In extended desktop mode, the maximum size of the external display is 1920 by 1200 at 60 Hz.
    So in extended mode the 1680x1050 resolution should be avaiable.
    Hope it helps
