Mini diplayport to vga wont work on projector

I can't seem to get a Keynote presentation to work on a projector. I have a mini displayport to VGA adapter (Model: MB572Z/A) but can't seem to get a signal. Any suggestions? (MacBook Pro 17-inch, early 2009)

Still no go. I've gone into systems preferences, selected the "Detect Displays" and nothing. I've check to make sure it wasn't the projector so I tried it on my boy's Dell 19" monitor--nothing....on my Samsung 52" tv-nothing. Could the video adapter be bad? or the MiniDisplay Port? Don't know what else to do. Any suggestions?

Hello-
I am trying to project a film from an ipad mini with a vga cable to a projector. When tested, the film played, but the ipad did not mirror what was being projected, it was a black screen. I am trying to be able to mirror the devices AND figure out how isolate the window so I can use different menus with the film still playing.
Any one know an app or softward that i can use?
Thank you!

To move an iPhoto Library to a new machine:
Link the two Macs together: there are several ways to do this: Wireless Network,Firewire Target Disk Mode, Ethernet, or even just copy the Library to an external HD and then on to the new machine...
But however you do choose to link the two machines...
Simply copy the iPhoto Library from the Pictures Folder on the old Machine to the Pictures Folder on the new Machine.
Then hold down the option (or alt) key key and launch iPhoto. From the resulting menu select 'Choose Library'
and select the Library that you moved. That's it.
This moves photos, events, albums, books, keywords, slideshows and everything else.
Your first option didn't work because you imported one Library to another. Every version and thumbnail is imported like a distinct photo, you lose all your Albums, Keywords etc., the link between Original and Previews is destroyed, the non-destructive editing feature is ruined and so on. In summary: it's mess.
Your second option didn't work because you simply referenced her library on the old machine.

Does the "Mini DisplayPort to VGA Adapter" work with all Samsung tv models?

Does the "Mini DisplayPort to VGA Adapter" work with all Samsung tv models?

It's a VGA adapter. Nothing special about that. If your Samsung monitor supports VGA then it will work.
But why not go completely digital and use a Mini DisplayPort to HDMI adapter to skip the analog conversion? It also supports passing audio over HDMI.

Does the mini display to vga adapter work with a pc (win 7 64-bit)

Its not a thunderbolt adapter. its a mini display to vga adapter. my hp ency pc has a mini display port next to the hdmi port.

First make sure the mini-displayport is firmly seated. They are a bit "sneaky" in that they look like they are fully in but aren't.
I assume that windows has something similar to the mac Displays system preferences. So you need to check that and set if necessary the proper refresh rate and resolution for the projector.
how do i make it work or is it formated for macs only?
What's "it"? The projector shouldn't care where it gets its vga signal from (when using the proper refresh rate and resolution). The adapter is passive and just converts a digital mini-displayport signal to analog vga to pass over the cable (is the cable ok?). That leaves your laptop. I can't speak about it or its video card. But I have to assume that if it supports mini-displayport it should follow the standards for mini-displayports.

Mini displayPort to VGA wont detect DELL E228WFP

i bought a brand new mini display to VGA adapter for my late 2008 macbook pro 2.53 connecting to dell e228wfp wont do a thing.
just wont work,
also not on a sharp prjector.
i tried booting with the lid closed and i get the grey startup screen on my dell but then it glitches away...
in Displays menu, the detect screens doesnt do a thing.
this is sooo frustrating as im involved in a huge project witch is stuck on this matter.

Is the monitor working? Tried its self-test?
Self-Test Feature Check (STFC)
Your monitor provides a self-test feature that allows you to check whether your monitor is functioning properly. If your monitor and computer are properly connected but the monitor screen remains dark, run the monitor self-test by performing the following steps:
Turn off both your computer and monitor.
Unplug the video cable from the back of the computer. To ensure proper Self-Test operation, remove both Digital (white connector) and the Analog(blue connector) cables from the back of the computer.
Turn on the monitor.
You should get bar test patterns ....

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.

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.

Will a Mini-Displayport to VGA adapter work with new macbook pro 2011

I was thinking of getting a mini-displayport to vga adapter for my external monitor I wanted to hook up but I wasnt quite sure whether it would work as my macbook pro has the new thunderbolt port, I was confused if the new port would only work with the thunderbolt displays. Could anyone help me as I'm not too sure what will work.

I tried the Apple miniDisplayport to VGA in a Thunderbolt MBP and iMac and they both worked. Same for the Apple miniDIsplayport to DVI.

Mini displayport to VGA not working anymore

Hello Everyone,
Macbook Pro 10.9.5 Mavericks
Mini displayport to VGA adapter to beamer
I recently bought a mini displayport to VGA adapter cable to use my beamer as an extra display.
The first 24 hours it worked and I could use the beamer as an external display which was great.
Only the next day it wasn't working and the beamer kept saying NO INPUT. My roommate has a windows laptop with VGA port and it still works on his laptop (before the incident and after).
I used the same cable only with the mini displayport to vga adapter inbetween it.
I tried everything to solve it.
     - Go to display and look for external desktop of mirroring (this didn't work because my macbook doesn't recognize it)
     - I did a PRAM reset
     - Did a SMC reset.
     - Tried the same thing on another beamer and it didn't work. With my roommate (his laptop) everything just works.
     - and finally i bought another more expensive Apple mini displayport to VGA adapter and it didn't work also
     - I repeated al the previous steps with the new adapter (PRAM, SMC, DIFFERENT BEAMER, DIFFERENT CABLE)
Still it doesn't work.
I really don't know what to do now. I just worked the first day and know my macbook doesn't even recognize it. doesn't matter which of the 2 ports (on my macbook) I use.
I hope there's is someone with a solution because I just don't understand why it's not working or ignoring my cable.
MacBook Pro (Retina, 15-inch, Late 2013), OS X Mavericks (10.9.5)

MBP CD2 DVI to VGA not working with projector

I am having issues getting the MBP to recognize a DELL 2300 projector through a DVI to VGA apple cable.
A few months ago there were posts about this, but no solutions. The problem seems to be with the 'INTEL' side of things, as the same projector with the same DVI to VGA apple cable works on an older G4 tower running 10.4.9. The projector also works on an old G4 iBook with it's version of a VGA adapter. To make things more confusing, a DVI to Video apple cable works with the DELL 2300 on my new MBP C2D-but produces a terrible quality picture. Mysteriously, my previous 1st generation MBP CD worked with the DELL 2300 via a DVI to VGA apple cable (but I'm not sure which OS was out at the time 10.4.8?)
My new MBP CD2 definately recognizes the projector through the DVI to VGA adapter, but the projector doesn't recognize the video signal from the computer. It is DEFINATELY the MBP (or universal drivers), as I have checked the DVI to VGA dongle (works), have checked the projector (works with an ibook running 10.4.8 OSX with VGA dongle), have changed resolution settings before and after connecting, have restarted computer, have tested various orders of connecting the projector and cables. STINK! (I also have TWO DVI to VGA adapters, so it is not a bad adapter). I have also played with exchanging various plist files from older universal versions of 10.4.8 that worked with the projector-no help.
As I stated, the projector will work (in horrible quality) with a DVI to Video dongle. Why it will not work with the DVI to VGA dongle is a mystery and annoying I would hope that a newer MBP CD2 would be plug and play (like my previous MBP CD and an old G4 tower and an old iBook G4...but no).
Any ideas, any help, any answers?

Here are the actors in our play today
1. MacBookPro A. (my system a CD2 2.16 with OSX 10.4.9)
2. MacBookPro B. (my friends system a CD2 2.16 with OSX 10.4.9)
3. an iBook (my friends 1.07 GHz G4 with 10.4.8 and a VGA adapter)
4. DELL 2300 MP projector
Plugged in DVI to VGA adapter to the virgin MacBookPro B (never had the projector plugged into it before) Dell projector shows that it recognizes an analog RGB 800X600 signal from MBP B. It projects a beautiful desktop. All is well for a moment.
In Display preferences we see for the MBP B
Color LCD, Display: 800X600 stretched, Colors: Millions, Refresh Rate: N/A
VGA Display
Now, I unplug the DVI to VGA adapter and naturally MBP B readjusts to it's native resolution. Great.
Now I immediately plug back in the DVI to VGA adapter. The computer and the projector searches for signal with none found, while the computer shows no attempt at an automatic readjustment as above (800X600 stretched).
I try the 'detect display' option. It causes computer to stall for a second (as it searches) but it does not detect projector and does not readjust it's own resolution to 800X600 stretched as it did initially. F7 key does nothing.
This is a problem!
So, I shut down the projector. I unplug the projector's power source and waited 20 seconds. plugged it back in, started projector back up.
I shut down/restarted the MBP B.
I plug back in the DVI to VGA adapter into the MBP B. The MBP B screen flashes to all blue, but does not automatically change to 800X600 stretched (remains at native resolution and does not recognize an external monitor/projector)
Enter the iBook!
I plug the iBook's VGA adapter into the projector. The projector shows that it recognizes an analog RGB 1024X768 60Hz signal and projects desktop screen immediately. Plug and play!
iBook display prefs reveal:
Color LCD, 1024X768, colors: Millions, Refresh rate: N/A
Color tab: Generic RGB Profile
VGA display, 1024X768, colors: Millions,
Now. I unplug adapter from iBook, iBook readjusts to native display
plugged back in adapter to iBook, immediately recognizes and displays projected desktop.
Scene 2: The FREAKY thing!
Now, I immediately (after unplugging the adapter from the iBook) change adapters to the DVI to VGA adapter and plug the projector into the MacBookPro B, whallla! Back in business. (computer screen adjusted to 800X600, and projector recognized signal).
Now, what about my computer? I unplug from MBP B and plug into MacBookPro A, and NOTHING...the computer doesn't automatically adjust to a new resolution, and the projector doesn't recognize any signal from the computer.
Ahhhh Freak out! Now, I plugged adapter back into MacBookPro B, and now back to NOTHING. MBP B no longer recognizes projector or readjusts it's resolution. Was something somehow corrupted?
Now, I plugged iBook VGA adapter back in, and iBook once again with it's awesome G4 technology (or dated video drivers or something) recognizes the projector in an instant and projects the screen.
Now, logically I try again to immediately unplug the adapter from the iBook and switch adapters and plug back into MacBookPro B-it worked once right? But, sorry, NOT twice. The mystery deepens.
Well, I think, maybe it is because I didn't restart MacBookPro B before attempting the switcharoo from iBook to MacBookPro.
So, I plug back into iBook-projector. And the iBook works immediately again.
I restart MacBookPro B and plug in to the freshly restarted MBP B...HOUSTON WE HAVE LIFT OFF! The MacBookPro B recognizes the projector and the projector kindly displays the desktop.
Now what about MacBookPro A...Last time, when I did the switcharoo, it corrupted something to cause the MBP B not to work. Let's try it again. Will this plug-unplug-restart-switch adapters-immediatly plug in technique work...let's see. I restart MBP A, and plug DVI to VGA adapter in. Sorry. Same ol' no signals recognized. MacBookPro A not auto readjusting resolution, and does not list any projector in display prefs.
Let's get crazy and immediately plug the adapter into the MacBookPro B...it works-oh so logical...NOT! Why wasn't it corrupted this time by MBP A? MacBookPro B readjusts its screen to 800X600 stretched and projector immediately recognizes and projects desktop.
Now lets see if I can break it again as before. I unplug it from MacBookPro B and back into MacBook Pro B, knowing that this caused it to stop working previously. And...it still works-WHAT? I do it a third time. It still works on MacBookPro B.
So,
I plug it back into MacBookPro A...still nothing. Back to MacbookPro B works like a charm. This time it struggles a bit showing that initially it sees a signal from MacBookPro B of 1192X900 (i Think), then the MacBookPro B switches automatically to 800X600 and the projector works.
Wait..I see something amiss! I see in my MBP A menu bar an icon for Labtick which MBP B does not have. I shut down Labtick, plug back in the DVI to VGA adapter and 'Boom' the projector is recognized.
I unplug DVI to VGA adapter and plug back in to MBP A and 'Boom' the projector is recognized again...no it couldn't be!
Well, it is possible it couldn't be because, I shut down the projector, unplug it's power source, plug it back in. I plug it back into the recently working MBP A with Labtick not running, and sorry folks, now the projector doesn't work again. The MBP A does not readjust it's resolution, nor recognize a projector and the projector doesn't recognize the MBP A.
Let's try the projector in MBP B....same deal. Now it doesn't work. Same symptoms of MBP A.
Back to the good ol' iBook. Of course it works.
Now switching over directly to a restarted MBP B. -DOESN'T WORK (as it did using this technique previously)
Now switching over to MBP A- DOESN'T WORK.
As you can see, it is hard even with multiple computers to find a series of doing things that consistently makes the projector work.
Any thoughts, ideas, ways to diagnose? Thanks!

Mini display to vga not working on 2010 Macbook Pro

I'm trying to hook up my MBP to an external display but it kept showing "No Signal" on the external display. I have verified that the mini display to VGA adapter is working as I've tried it on a separate MBA and 13" unibody MB.
I brought it down to the service centre and they've replaced the motherboard for me but it's still the same. I have also tried the SMC reset but to no avail.

Lenovo X1 mini-Displayport to VGA not working

Hi,
i recently needed to re-install a Lenovo X1, but i didn't have a Lenovo Windows-7-Image, so i used another one instead.
After installing, i updated all the drivers, using the ones provided on this page: http://support.lenovo.com/de/de/products/laptops-and-netbooks/thinkpad-x-series-laptops/thinkpad-x1
Unfortunately, the mini-Displayport does not seem to work. I tried to connect a mDP-VGA-Adapter, to connect it to a beamer and it didn't work, neither did it with another adapter.
Also i tried connecting it to a TV, also didn't work.
Any help how i could solve this problem?

Mini display port - vga only works with lid closed - then computer goes to sleep

my problem is simple, but strange.
I have a 2009 unibody macbook pro. I have 42 in lcd tv. I have a minidisplay to vga adapter and a vga cable. When I try to connect the monitor to the mbp when the lid is open nothing is detected. I do not get any options to change to mirror mode or am able to change any settings regarding the monitor. I can change the resolution of the built in display only. Now for the twist.
If I connect everything, do a restart and close the lid, as the computer boots up the external monitor works. Its the grey boot screen with the apple logo. But as soon as the computer begins to load the desktop, the monitor losses the signal. At first I thought it was going into sleep mode, so I hooked up a usb mouse to keep the computer awake. I tried the process again, and as soon as it goes to the desktop it losses the signal. So I don't think it is sleep mode.
I downloaded the minidisplay prot firmware update, but because the screen is not detected when the lid is open I cant run it. When the lid is closed the computer either goes to sleep or doesn't send the desktop signal and I still cant run it.
Nothing happens if I change between the video cards (9400 and 9600gm). Is it a resolution issue? Do the vga cables have a max resolution that is lower than 1900 x 1200?
What should I do? thanks

see all this time you DID have the info i was looking for:
"Do the vga cables have a max resolution that is lower than 1900 x 1200?"
3 posts later
"The VGA displays Apple has typically in the past offered only had 1024 x 768 resolution at most."
im sorry I inticed you to giving me the information i needed, but i guess it was required. you have earned your 10 points today.

Why won't any Mini DisplayPort to VGA adapter work with my 2012 13" MacBook Pro?

Hello!
A few month ago, I purchased a new 2012 13" MacBook Pro. I quickly realised that my non-Apple MDP to VGA adapter was not working, but put off the problem as it wasn't neccesary -- and I thught that the adapter was to blame. However, after using the adapter sold by Apple, I can asafely say that the problem is with my computer. In review on the product, several 2012 MacBook Pro users mention this. I was hoping someone here would be able to point me towards a solution! Thank you.

I tried the Apple miniDisplayport to VGA in a Thunderbolt MBP and iMac and they both worked. Same for the Apple miniDIsplayport to DVI.

Mini dvi to vga wont fit

just bought the cable but it doesent seem to plug in maybe theres a different cable

I use the mini-DVI to DVI cable with my BlackBook and it fit perfectly. Not to belabor the obvious, but the cable is keyed to fit only one way. Did you try turning it over to see if it would fit that way?
