Mini-DVI to VGA issue

I'm trying to have my display go to my 26" Vizio tv.
However, when everything is plugged in, the display isn't showing up on the TV.
Any Help?

This seems obvious, but I have to ask; is the Vizio set to the VGA input?
Have you tried alternate resolutions and refresh rates for the Vizio within Displays Preferences? If none of them causes the Vizio to light up, it could be a basic incompatibility between the Vizio and the MB over VGA. Some displays terminate the VGA horizontal and vertical sync lines into too low of an impedance for the MB, and it becomes unable to drive those lines to critical TTL threshold levels. If that's what's happening, you could try getting a Mini DVI to DVI adapter and a DVI to HDMI cable and see if you get a better result out of that.

  • Mini DVI to VGA issues w/ LCD HDTV

    I have looked all over and I can't find a solution.
    I recently purchased an LCD HDTV, Insignia Brand which is a Best Buy Brand, and I bought a DVI cable to hook up to my Powerbook G4 using the Mini DVI to VGA cable. When I hook it up to my tv it works, but the screen on my Powerbook looks magnified as does the LCD TV. When I launch Safari or any other program it doesn't fit on my screen or the LCD TV and I have to resize it.
    After I look at displays in system prefernces it says my max resolution is 1024 x 768.
    Any help would be appreciated.
    Jeremy

    Just guessing - the TV's "VGA" input is limited to 1024x768, which is possible although some "VGA" inputs will work higher. Do the instructions mention a limitation like this?
    I think if you turn off mirroring on the Powerbook, at least the Powerbook screen will have normal resolution, and the TV 1024x768. The TV apparently scales up image to fill the screen unless using HDMI, where is leaves the extra 342 pixels blank on the sides (1366-1024). Perhaps the TV has a mode for adjusting how the TV handles lesser resolutions (stretch, dot-by-dot, etc)

  • 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.

  • 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 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.

  • 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 not working

    Hi,
    I've searched in the discussions forae to see if this issue has happened before, but it doesn't seem so.
    I have a new MacBook 13 in duo 2 and tried connecting a secondary display with a mini-dvi to vga adapter that I bought 2 years ago....and it doesn't work! No image appears on the second display and when I press detect display on the display preference panel, nothing happens.
    Does any mini DVI adapter work (the one that fits with a U connection)? Or maybe I need a newer one?
    Pablo

    I don't know what part number it is (it doesn't have a number anywhere), but it fits in the Mini DVI port. I would assume that any adapter that fits should work. If it doesn't work,then maybe the adapter is broken.....or my video output is broken!
    I'll try to get another one a test it.

  • 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!!!

  • 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:

  • Mini dvi to vga not working properly

    I have a Macbook from around 2008 and it has a mini dvi port. I have a mini-dvi to vga adapter going to my Vizio 32 inch TV's RGB port.  I have tried two adapters, and they both have problems.
    The display works fine coming from both of my G5s, which are running DVI to VGA to to the VGA cable to RGB port.  However, when I run the mini-dvi out of my Macbook, it does bizarre things.  It resets the display on my Macbook, and displays only part of the information on the Vizio screen.  For instance, the first adapter would show the wallpaper of my Mac, but would not show the icons on the TV.  This second adapter does the reverse.  The icons disappeared from my laptop, but showed on the TV.   The mouse shows sometimes on the TV, sometimes only on the Macbook. Etcetera.
    What's going on here?  This should work.  Grateful for help and suggestions. Thank you.

    Oh, it won't let me edit, so here's an added note:
    This time I started the macbook with the adapter plugged in, so that it didn't have to adjust.  It booted normally, with normal color, recognized properly on the TV, and then went to teh login screen.  All normal.  Once it booted into my login, and everything loaded on the desktop, the blue haze covered the screen.  This happened twice.  The first time, I hard-rebooted - and for some reason it's sort of loud and sounds like it's working very hard to reboot.  The second time I unplugged the adapter, the laptop tried to reset itself, and showed the icons, but not my picture in the middle of the wallpaper or the program bar at the bottom.  It did not respond properly to the restart command, hanging upon shutdown, so I  did a hard-shutdown again.
    EDIT
    Okay, it must be somewhere in the settings.  I am logged in from another login on the machine, which I keep as a control.  It is working fine, no issues.  I will somehow have to trace down the problem?  THe other login is my main and everything is loaded on that one.  Does this issue sound familiar to anyone?  welcome any guidance. 
    Thx.

  • Mini-DVI To VGA Problems W/ iMac Late 2006

  • Macbook 13" Core 2 Duo, Mini DVI to DVI will not work (Mini DVI to VGA OK)

    I've recently purchased a used Macbook 13" with a Mini DVI out display port. When I try to use a Mini DVI to DVI adapter to an Acer X223W (or a few other Acer / Dell models), the Macbook screen either blinks blue to white constantly or doesn't do anything at all. When I use a Mini DVI to VGA adapter, it works fine, however, the MAC does not give an option for my monitors native resolution (1680 x 1050).
    At first I thought there was a physical issue with the Mini DVI port, however the VGA adapter works fine. I've also tried a new DVI adapter in case the first one was defective - same results.
    Am I missing something here? I don't think there are options to upgrade drivers on a MAC (I'm semi-new to the platform).
    Thanks in advance!
    Dan

    What happens if you try just the monitor, e.g. keep the lid down on the MB? The MB should be attached to it's AC adapter to try this. Also, some kind of USB device will be needed to wake up the closed MB. Pretty much anything hot-plugged into a USB port on the MB will cause it to wake up. Would be curious to know if a DVI monitor works under those conditions.

  • Possibly mundane Mini-DVI to VGA into an external monitor problem

    Hi,
    I've had a look over the interwebs regarding my problem and it seems as if it's not unusual to have external monitor problems but I'm not sure if mine is slightly different:
    I had a perfectly working set up with my new Macbook (the white one, '06 model I believe), that was connected to my Hanns-G HU196D monitor via a mini-DVI to VGA adapter, no problems whatsoever. But for a couple of weeks now my Macbook just flickers a light blue colour, with nothing at all on the monitor, and my macbook is unusable until I remove the adapter. I've read about updating firmware but I can't see my desktop once the macbook is connected to the monitor so it's not possible to configure anything. I've read somewhere that my external monitor isn't compatible with this set up, but it was until a couple of weeks ago!
    My Macbook's 4 months old now and since then I've bought a new mini-dvi to vga adapter and a new VGA cable, no connections seem loose on either mini-dvi port or my monitor's vga port.
    Thanks if you can help!
    Jack

    You will need to use a mini Dvi-dvi and a dvi-svideo/rca adapter.
    Joy joy hallelujah.
    Pardon the sarcasm...I just wasted 3 hours of my life trying to sort the issue out.
    Heard a KWORLD PlusTV PCTOTV Converter SA235 USB 2.0 Interface would sort the issue out for under 40$ but it's not Mac.
    Hope that helps.

  • Mini DVI to DVI to HDMI Vs Mini DVI to VGA

    When I connect my MacBook to my LG 32" HD Ready LCD TV via Mini DVI to DVI connector and DVI to HDMI cable, image is sharp but color seems very pale and washed out. However, when using Mini DVI to VGA connection, colors are brilliant, though images via DVI are sharper.
    I tried calibrating the display but couldn't achieve the brilliant colors of the VGA connection.
    Is this normal? Any solution for this?
    I'm also connecting my PS3 to my TV via HDMI and don't have this problem.

    Hey Guys,
    I am having a very similar problem.
    I have a 35" Westinghouse LCD TV (not the best I know but I'm a college student). I had been using a VGA adapter/cable in order to use my TV as a monitor, but I decided to upgrade (or so I thought) to a digital signal so I purchased a Mini-Dvi to HDMI adapter, etc.
    Here's the problem:
    My display settings on my MacBook for my LCD TV only allow me to choose either '1280 x 720' or '1920 x 1080'. My TV cannot support the higher resolution so when I chose the '1920 x 1080' setting, the picture comes up with good color quality, but the actual image looks over compressed and does not fill up the screen. When I choose the '1280 x 720' setting, the image resolution looks great, EXCEPT the colors are way off, faded, washed out, etc.
    This is problem is so frustrating because I can get the resolution to look good OR the color to look good, bot never both. I have read several forums that touch on a similar issue and have tried all types of monitor calibration but I can't get the color to look normal when the resolution is right.
    I just don't understand why the only resolution that fits that of my TV has terrible color??
    Help would be greatly appreciated.

  • 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?
