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.

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.

Macbook mini-dvi to vga display resolution issue

Hi,
I'm connecting my 13in first generation macbook to an external LCD display. It's an ACER AL2216W. I'm running latest Snow Leopard.
I could always just click 'detect displays' and it would figure out what kind of monitor I had and I would be off and running at the native 1600x1050.
Now for some reason when I click detect displays, it only shows the laptop native resolutions. There is no 1600x1050 in the resolution list and instead of saying "ACER AL2216W" at the top of the display preferences, it just says "Display"
I've tried rebooting, plugging in and and out my monitor cable to the macbook and a variety of other things but to no avail. I'm forced to use 1024x768 right as it is the only resolution that displays correctly on my monitor.   Any ideas on how to get back the detect display working and have 1600x1050 resolution again?

I have a 40 lcd tv and have my macbook hookuped to it using the mini display port to vga and it looks really good, but i only use it for watching movies. Dedicated monitors are still better for reading text or playing games

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!!!

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
Bob

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 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?

Preferred adapter for VGA? Mini DisplayPort to VGA or Mini-DVI to VGA?

Which is the preferred adapter for connecting a VGA-only LCD display to the new Mac mini?
The official Mac mini accessories page <http://www.apple.com/macmini/accessories.html> prominently features the Mini DisplayPort to VGA Adapter.
However, the Tech Specs knowledge base article <http://support.apple.com/kb/SP505> suggests the Mini-DVI to VGA Adapter.
I'm sure Mac OS X will work fine with either. But is one more likely to work better with Windows XP using Boot Camp?

I've come up with my own answer to my earlier question...
It's the Mini-DVI to VGA adapter.
I ended up trying both adapters, and got the results I described here: [http://discussions.apple.com/thread.jspa?messageID=9255959].
Besides the simple fact that the Mini-DVI to VGA adapter is the only adapter that fully worked for me, it's also cheaper.
Also, from a mechanical point of view, the nuts to secure a VGA cable to the DisplayPort version of the adapter are recessed into the end of the connector housing. This prevented my VGA cable from being able to be properly secured to the adapter--although this might be a defect with my cable!

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 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

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!

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 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 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.
