Mini displayport to vga issue

I am trying to connect my MBP to multiple projectors(via vga distribution amp) using the mini displayport to vga adapter. It will recognize and correctly connect to each projector individually but will not connect to all simultaneously. Have a macbook w mini dvi to vga adapter that works fine both individually and simultaneously but for some reason the MBP will not. any help would be greatly appreciated.

I bought my Mini DisplayPort to VGA Adapter last May and only had the chance to use it now for my presentation. When I connected the cord of our LCD Projector to the Mini DisplayPort to VGA Adapter, it didn't work. I thought the cable was problematic and so I used another one but it still didn't work. After my presentation, another friend used the same cable and her Mini DisplayPort to VGA Adapter for MacBook. Her Mini DisplayPort to VGA Adapter worked. She said she just connected the Mini DisplayPort to VGA Adapter to the cord of the projector and it already worked. Is my Mini DisplayPort to VGA Adapter problematic or is there something I forgot to do that's why it didn't work? It's the first time for me to use it and can I have it replaced just in case it really isn't working?

Macbook air Mini DisplayPort to VGA Adapter connectivity issues

Hi pple,
Would like to ask if anyone is facing connectivity issues with Mini DisplayPort to VGA?
I am currently using the 2nd Gen Macbook Air with Intel HD Graphics 3000 384 MB. Sometimes when I connect to a montior (Viewsonic VA1918wm) it works fine, sometimes it just does not work and the laptop just shows me a blue screen.
I tried with out with my friend's Mini DisplayPort to VGA adapter, it has the same problem. Does this means that my macbook air mini disoaly port got a problem?
Thanks
Bryan

I am experiencing the same kind of problem... only with projectors. Some projectors will display the screen and then others wont even register with the MacBook Air.
Using an Apple Min Displayport to VGA adapter. It's hit or miss if it works. Firmware has been updated on the adapter but this did not help.
Anyone help with this?
Thanks,

Apple Mini DisplayPort to VGA Adapter flickers

I have 2 Samsung SyncMaster 23 in, HD Displays connected to my Mac Mini. The Display connected via the Mini DP to VGA adapter flickers erratically. This started happening after installing the latest upgrade of OSX Mountain Lion. I called Apple support, they gave me a list of steps to try to fix the problem, which I followed to the letter, to no avail. The problem is annoying, to say the least. I tried to find out if there was a firmware update for the adapter, but I am running the latest firmware (1.03).
I would appreciate any help to solve this issue.

Thank you for your message.
1. Both monitors only have VGA input.
2. The other adapter, Mini-DVI to VGA has always worked properly.
3. The Mini DisplayPort to VGA adapter is an Apple original product I bought at an Apple store. I bought 2 adapters.
4. Actually I have 2 Mini DisplayPort to VGA adapters: The one I use with my Mac Mini, and another adapter I use to connect my Mac Book Pro to a Panasonic projector.
5. I have tried using both adapters, and the flickering problem is present using either adapter.
6. I believe the flickering problem is definitely something that needs to be addressed and solved by Apple. The adapter is its product, and should work as advertised, no matter what version of OSX I am running. Please remember that there was no flickering before I upgraded to the latest OSX Mountain Lion.
7. I do not believe buying an adapter from another manufacturer, as you suggest, would solve the problem.
Thank you for your help.

No image on screen using Mini DisplayPort to VGA Adapter

Received mini today. After unboxing, read through the packet. Then began to hook everything up as directed. I used a Mini DisplayPort to VGA Adapter to connect the monitor from our now dead desktop to the mini. After double checking all connections, I hit the power button. I immediately heard the apple chime. Then the monitor showed the grey apple start up screen. Suddenly the monitor went black and said it was going into sleep mode. I can't get it out of sleep mode when connected to the mini. It is NOT the monitor or the adapter. I plugged the monitor straight into a netbook and it worked. Then, I plugged the monitor using the adapter into my MacBook Pro and also got it to work that way. So I tried replugging the adapter into the mini. Still can't get an image on the screen. I can't complete set up or use mini because I can't get an image. Any suggestions or ideas? I will call apple in the morning if I can't figure it out tonight. But I'm hoping someone can give me suggestions. Thanks for your help!

I had the same issue when I bought my mac mini last week apart from I wasn't even getting the initial grey screen. I went back to the Apple shop and they gave me another mini and fired it up in the shop using the adaptor on an old VGA monitor. It worked perfectly.
When I got home I set it all up again and still had the same issue. I nearly threw out a couple of monitors as I thought they were broken.
However, had a look around the web and found this suggestion:
Shut down the mac and disconnect the adaptor from it. Now fire the mac up and let it boot up FULLY. Once it has had a chance to boot up fully, only then plug the adaptor in.
Worked for me and I haven't had the issue since (touch wood). Hope this helps.

Mini-Displayport to DVI adapter not working, but Mini-Displayport to VGA and Thunderbolt work fine

Mini-Displayport to DVI adapter not working, but Mini-Displayport to VGA and Thunderbolt work fine.
This is a brand new MacBook Pro (15-inch, mid-2012) just received. I suspect that this is a hardware problem as:
The mini-displayport to DVI adapter and the external monitor that I am utilizing connect and operate just fine using my older MacBook Pro (mid-2010) with the same OS.
The new MacBook Pro powers the external monitor with a mini-displayport to VGA adapater without issue.
The new MacBook Pro powers an Apple Thunderbolt display without issue.
Both MacBook Pro's are running OSX Lion 10.7.4.
The only combination which does not work is the mini-displayport to DVI adapater used in conjunction with the brand new MacBook Pro (mid-2012).
All adapters and components (mini-displayport adapters) are Apple retail adapter.
I have tried several external monitors, including my Dell U2412m.
When I connect the mini-displayport to DVI adapater to the new MacBook Pro (mid-2012), nothing happens. The external monitor reports "no signal" and attempts to go into sleep mode. Using the "Detect displays" button has no effect, even when used multiple times. Rebooting does not help, nor does resetting the SMC or PRAM.
Any other suggestions before I take it to the Genius Bar?

I turns out that the logic board of my MacBook Pro was faulty (despite being brand new).
I took it to the Apple Store, presented the problem, and one of the Tech's came to the same conclusion that I had -- hardware failure. Phone support was no help in the matter (and even told me that what I was trying to do wasn't a supported option, which is rediculous). However, the Genius Bar did take care of the problem, and my MacBook Pro was back to me with a replaced logic board within a few days.
Hope that htis helps.

Getting a Mini DisplayPort to VGA Adapter & Monitor to Work with an Xserve

First let me say that I'm very new to Xserve's and OS X Server and any help is greatly appreciated.
I have an Xserve with a connected Mini DisplayPort to VGA Adapter and a confirmed working VGA monitor. There is also a keyboard and mouse plugged into the front USB port of the Xserve. The internal SSD has been formatted clean.
I've been trying to boot up from the optical drive on the Xserve using the 10.6 DVD. I use the front panel/system identifier button to boot up and I make sure enclosure lock is unlocked. Each time I try to boot up, the monitor stays off and the DVD is spit out.
I eventually got the DVD to stay in, and the screen showed the grey screen with black apple and the spinning black circle on the bottom. However, after a few minutes the screen turned orange in color. Using Screen Sharing, it looked fine. I tried a second VGA monitor, but that still didn't do it.
So with the DVD still in, I stay connected via Screen Sharing and begin the installation process remotely, thinking Snow Leopard will recognize the monitor eventually. Well, 10.6 is now fully installed, but still no working monitor.
I then decided to try the Mini DisplayPort to VGA Firmware Update. I download and run the installer, but it tells me, "The Updater could not find a Mini DisplayPort to VGA Adapter to update."
How can I possibly get this monitor working?
Thanks in advance.

Just ran in to this myself -- Nehalem Xserve running 10.6.2 Server with an MiniDisplayPort to VGA adapter connected to an Avocent Switchview 1000 KVM. Took the server offline to install RAM and after rebooting, no video. Oddly enough, the KVM's LEDs showed a display connected but Apple System Profiler showed no adapters connected to the video card. Nothing seemingly worked -- rebooting, shutdown/restart, and/or hot-plugging the adapter made no difference. I also tried a second MiniDisplayPort adapter to no avail.
Note that the MiniDisplayPort to VGA Firmware update had already been applied to BOTH adapters prior to this issue appearing.
What restored video output on our system: reboot from the Snow Leopard Server install media, video reappears over the adapter, and after that I can reboot from the SSD boot drive running 10.6.2 Server with video output working over the MiniDisplayPort to VGA adapter.

Mini DisplayPort to VGA adapter not working under Vista (Boot Camp).

Hi there,
I'm facing a very serious issue with MacBook Pro Unibody running MS Vista under Boot Camp: using the Mini DisplayPort to VGA adapter to hook a projector is 95% impossible because the only resolution available is 640x480 or sometimes 800x600. No solution came from the adaptor firmware update, still same behavior: connecting the external projector/monitor toggles 640x480 resolution with no more choices available. Just 5% of attempts on selected projectors gave me access to the complete resolutions list.
This is having a serious impact on my job where I do need both Mac&Windows running natively and with external display capabilities, please I'm looking for some feedback from users facing the same problem or someone who had an official answer on this issue from Apple. Do avoid posting about using modded display drivers please: I know they exist but the adaptor should be working with original ones.
I can understand Apple does not support MS Vista issues but this seems to be a hardware/driver one.
I'd like to point out I'm using a clean Vista installation with Apple drivers (from the Leopard DVD) and I've run Vista (same version, same gfx drivers etc) under Boot Camp on my previous MPB (with integrated DVI output+adapter) on hundreds of different projectors with never a single problem.
Any feedback is really appreciated.
L.

I'm having the same problem. When I try to connect to the switch in our conference room (connecting both a flat panel display and/or a projector, both with much higher native resolutions), all I get is 640x480. This is a huge problem to using bootcamp, and I really need to get this to work. I was able to get a higher resolution 1280x800 on a separate, portable display, so I'm wondering if people have the problem with standalone projectors or only with projectors connected to some sort of switch, in my case an Extron MPX423A. I have also tried this in both Windows Vista (32-bit) and Windows 7 RC1 (32-bit), with the bootcamp drivers and the latest NVidia drivers, and the behavior is the same all around.

Mini DisplayPort to VGA Adapter won't work on thunderbolt port

Hello
I bought 2 new Macbook Pro 13' , 2.9 Ghz Intel Core i7, with 8 Go 1600Mhz DDR3, Intel HD Graphics 4000 512 MB, Mac OS X Lion 10.7.4 (11E2617).
I have connected a Mini DisplayPort to VGA Adapter in order to show presentations on different LCD projectors but no image appear.
The external monitor is detected but no image is shown. I have tried to change the frequencies: parts of the screen appears but no a correct image. I have the same symptoms with the 2 Macbook Pro. Using old Macbook Pro with the same Mini DisplayPort to VGA Adapter, the slides are showns normally.
I make a test with a Mini DisplayPort to DVI Adapter and with a Mini DisplayPort to HDMI Adapter and everythings works correctly with both adapters.
Does anybody has a solution?
Thank in advance for your help
Philippe

By any chance were you using a VGA->DVI adapter when trying to use the Mini-DisplayPort->VGA adapter? As in Mini-DisplayPort->VGA->DVI?
I had trouble with this. I found going straight to Mini-DisplayPort->VGA or Mini-DisplayPort->DVI worked perfectly but once I added a VGA->DVI or DVI->VGA adapter to the chain the screen would be detected by OS X but the monitor itself would give the "No signal detected" message. I tried all these combinations on the same monitor.
Not sure if it helps your situation but I have noticed some similar issues.
EDIT: Oh, and I have the new MacBook Pro 15inch with Retina all fully updated. I noticed that with my late-2009 White Macbook didn't have this issue with the cables and adapters.

Mini DisplayPort to VGA Adaptor not Mirroring

13-inch MacBook Pro (Mid 2012) running 10.8.3
Monoprice Mini DisplayPort to VGA Adaptors freeze the system (no issues with Monoprice Mini DisplayPort to DVI connected to monitor) so I tried an Apple Mini DisplayPort to VGA Adaptor and that works ok, EXCEPT it doesnt automatically mirror to projectors like older models I have used.
Is the 13-inch MacBook Pro (Mid 2012) supposed to auto mirror when connected to projectors using Mini DisplayPort to VGA Adaptor?
Thanks for any assistance.

I havent had a chance to test, yet it looks like if I create the settings for mirroring when the projector is attached to the laptop, the setting should stick moving forward.. I thought it just auto-sensed. Will try and report back here if there are any changes or to solve the ticket...

Does Mini DisplayPort to VGA adapter support DDC/CI?

I have a Mac Pro and a MacBook5,1.
Mac Pro is attached to a BenQ monitor which supports DDC/CI communication.
With a capable software I'm able to set brightness and contrast of the monitor without using monitor's OSD (thanks to DDC/CI communication).
If I attach the same monitor to my MacBook5,1 with VGA cable through a Mini DisplayPort to VGA adapter, DDC/CI stops working.
I'm no more able to set brightness and contrast and the app reports that monitor isn't DDC/CI capable.
I'm sure its not an issue related to the app that I'm using to set brightness and contrast. It detects correctly both of the monitor (the internal and the external one) and I'm sure that I'm sending DDC/CI commands to the external monitor and not to the internal one.
So, does Mini DisplayPort to VGA adapter support DDC/CI, and therefore passthrough its signal?
Or is it a problem of MacBook and its Mini DisplayPort which does not support DDC/CI at all? I don't think so.
I hope you can help me.
Regards
Andrea

No. Unlike DVI, which in the DVI-I configuration has both digital and analog pinouts, DisplayPort (and mini-DisplayPort) are purely digital. Mini-DP to DVI then DVI to VGA will not work. If you look carefully at the Apple Mini-DisplayPort to DVI adapter, you'll notice it's a DVI-D connector - digital pins only.
The Apple mini-DisplayPort to VGA adapter contains a digital-to-analog converter.
So, you'll have to choose. If you want VGA, get Apple's mini-DisplayPort to VGA adapter.

X1 connectivity problem with old VGA beam projector using mini displayport to VGA adaptor.

Hi all,
I would like to ask you how to connect this X1 with VGA projector as well.
actually, X1 has a external interface specification as mini displayport 1.1a.
So I bought mini displayport to VGA adapter from MAC store.
(Actually, Lenovo Korea office doesn’t sell this adapter directly on Korea, even in the future.)
and try to connect both of LED monitor and beam projector.
LED monitor was worked as well. but, this adaptor doesn't work with VGA projector. TT
Please help me how to work this adaptor with projector as well.
Solved!
Go to Solution.

Hi everybody. I was having the same issue here, but I bought a Mac minidisplayport to VGA adapter. It worked on my Monitor but it was not working on my clients VGA beam projectors. But today I figured out a way to make it work, and it is pretty easy; just change your laptop screen resolution.
When you connect the mini Dport to VGA adapter to the projector VGA receiver cable, just change your laptop screen resolution to 1024x768 (maximum) and the projector will receive the signal with no problem.
This is the best solution that I found, because is easy to find a Mac/Apple Mini display Port to VGA adapter.
Hope this works for you too.
Regards,
J.

2013 27" iMac using mini displayport to VGA, external monitor off center.

I recently purchased a new 2013 iMac 3.5 i7 and connected two external monitors. The minidisplayport to DVI adaptor works fine on one monitor but the minidisplayport to VGA is off center on the 2nd monitor. There is a 2" black band on the left side of the screen. I've replaced the adaptor, cable and tried on two different monitors. I've also tried repositioning image in the monitor settings which it can't move far enough. It only happens on 1920 x 1024. Any other resolution is fine. Other than that it works fine, but this space is going to drive me nuts. Because these are 23" monitors I really would like the highest resolution possible. I'm stuck. Any thoughts?

Update: I switched to DVI and it worked perfectly. I guess there could be an issue with the mini displayport to vga adaptor on the 2013 iMac. I also tested it on a 2012 mac mini and the vga operated as it should.

Thunderbolt (Mini DisplayPort) to VGA doesnt support Full HD Properly?

Hello,
Last month, I've bought a MacBook Pro 15" 2011 Model with 2.2Ghz Intel i7 2nd Generation with AMD 6750M. I've also got a Mini DisplayPort to VGA adapter in order to connect it to my FULL HD Samsung 23" monitor. The display works fine but there is a lot of flickering going on. Also whenever I set the screen resolution to 1920 x 1080, the screen gets shrinked and moves to the sides. Half of the screen is beyond the limits of the display ,that is, i cant see the left half of the display. I've tried changing the monitor setting also but no use . Tried connecting it to windows (using BootCamp) but still the result is the same. All other resolutions work well but the native resolution of the monitor is 1920 x 1080, So i'm in dire need of it...Please help

Mini displayport to vga limits second screen resolution in VMWare Fusion

I am using a Mini Displayport to VGA adapter which works fine in except when I use it with VMWare fusion. In VMWare I am unable to use the secondary display effectively. My screen does extend but I am unable to interact with anything on the second monitor.
help!

Hi m,
This sounds like it could be a Fusion issue. If you don't get help here, you may want to contact Fusion's tech support.

Thunderbolt display: devices not discovered after using Mini DisplayPort–to–VGA adapter

I have an interested problem related to using my MacBook Air in clamshell (closed) mode, connected to a Thunderbolt display. The problem appears to be related to moving my MacBook air between my office and my home.
At the office, I use the MacBook Air with an external VGA display, connected via the Mini DisplayPort–to–VGA adapter. At home, I use the MacBook Air together with a Thunderbolt display. An Apple USB keyboard is also connected to the display.
Mini DisplayPort–to–VGA adapter implicated
The following sequence of events causes the problem to occur:
Use the MacBook air (open) together with a VGA display, connected via a Mini DisplayPort–to–VGA adapter (depicted at right);
Put the MacBook Air to sleep by closing the lid, and disconnect the Mini DisplayPort–to–VGA adapter (I am not sure if the order of these two steps is significant—I usually perform them almost simultaneously when packing up my MacBook Air and getting ready to leave the office); and
With the MacBook Air still closed, connect it to a Thunderbolt display with a connected USB keyboard.
At this point, I would expect to be able to wake up the MacBook Air by tapping on the space bar of the keyboard. However, what I have observed is that this does not wake the MacBook Air.
I can wake the MacBook however by moving or clicking a Bluetooth mouse that is paired with the MacBook Air.
At this point, although the MacBook Air is awake, and the display is working, the USB keyboard connected to the display still does not work. This is the problem, in a nutshell.
Unplugging the USB keyboard from the display, and plugging it back in causes the MacBook Air properly to identify the keyboard.
I used Apple System Profiler to save a list of identified devices at two points in time:
Immediately after waking the MacBook Air by moving the Bluetooth mouse (at which point the USB keyboard was not working); and
After unplugging and plugging in again the USB keyboard (at which point the USB keyboard worked fine).
Many devices are enumerated in the second list that are missing from the first. For example:
Keyboard Hub@fe110000 <class IOUSBHubDevice, id 0x1000378ef, !registered, !matched, inactive, busy 3 (37993 ms), retain 6>
AppleUSBHub <class AppleUSBHub, id 0x1000378f2, !registered, !matched, inactive, busy 1 (37987 ms), retain 6>
IOUSBInterface@0 <class IOUSBInterface, id 0x1000378f4, !registered, !matched, inactive, busy 1 (37986 ms), retain 6>
Keyboard Hub@fe110000 <class IOUSBHubDevice, id 0x1000378f6, registered, matched, active, busy 0 (7 ms), retain 10>
AppleUSBHub <class AppleUSBHub, id 0x1000378f9, registered, matched, active, busy 0 (1 ms), retain 9>
IOUSBInterface@0 <class IOUSBInterface, id 0x1000378fb, !registered, !matched, active, busy 0, retain 7>
Apple Keyboard@fe112000 <class IOUSBDevice, id 0x1000378fd, registered, matched, active, busy 0 (112 ms), retain 11>
and many child devices…
Using the Mini DisplayPort–to–VGA adapter appears to be a necessary step to causing this problem to occur. If I merely disconnect the MacBook Air from the display, let it go to sleep, and then reconnect it again, the USB keyboard will work immediately and can be used to wake the computer from sleep.
Some devices are discovered even when the computer is in sleep mode. This is how it should work.
The problem appears to be that when a Mini DisplayPort–to–VGA adapter has been used since the last time the computer was connected to a Thunderbolt display, the MacBook air does not discover devices completely when it is again connected to the Thunderbolt display while in sleep mode.
Can anyone else reproduce this problem?

Hi glraczon.support,
It sounds like the external display you are using (projector) operates at a smaller resolution than your MacBook Pro. You may want to configure the display preferences in System Preferences for the external projector.
Here is an article that may help you with that process:
