Mini displayport to VGA adapter to projector problems

I have had zero problems with this combination prior to update to Mavericks. I believe I had Snow Leopard.
Since the update to Mavericks, when I connect my Macbook (white), the projector shows a blank home screen with the shortcut bar, but no icons, cursor, task bar, or windows. Very puzzling, and I'm unsure what exactly is going on.
This is a problem, since I am a teacher and use my macbook intensively to project media, text, and usb microscopy.
Any suggestions would be greatly appreciated.

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.

Using Mini DisplayPort to VGA Adapter to connect Macbook Pro (2009) for a presentation via projector.

When I connect my Macbook Pro (2009 model) using a Mini DisplayPort to VGA adapter to display a presentation via projector, only the top-left portion of what is displayed on my Macbook Pro's screen is displayed on the projector, as though I zoomed in on that portion of my screen. The projector is on and the adapter and the cable that connects the adapter to the projector machine is correctly connected. Any suggestions on how to fix 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.

Mini DisplayPort to VGA Adapter problems

I connected my Apple Pro to my HD TV to watch streamed movies on my computer using the TV as a monitor. I was advised to purchase a Mini DisplayPort to VGA Adapter and all the connections fit. The first time I connected it was no problem. I watched the movie and the audio was fine. Then the 2nd time I connected I had no screen. It was a blue wavy screen on the TV, even though the computer screen was showing the show. I believe it may have been showing me some sort of screensaver application from what i've read on the forums but I have no idea why or how. Then the next day I tried again. The screen was fine but the audio quality was terrible. It was like listening through a cheap radio. Why am I having so many problems and the quality is not consistent. Are there settings I should change when I do this?

I have some good news.
Regarding the broken lines on the output of the Mini DisplayPort, it seems as though it "fixed" itself. My theory is, I recently installed Windows 7. Updated all the drivers on the windows side and got it to project properly with the new Intel 4000 graphic cards. Once that happened, it kind of "popped the cherry" on the port and now both Mac and Windows output properly through the Mini DisplayPort.
I've tested it with numerous adapters and once it outputed properly for the first time ever, all subsequent times work.
I now have tested in on LCD and DLP projectors, Philips monitors, Skyworth TVs, Sanyo TVs.
It's working with the Mini DisplayPort - VGA adapter.
It's also working with the Mini DisplayPort - DVI adapter as well.
Before I "popped the cherry" on the output port, nothing else worked. 1440x900 didn't work, neither did mirroring the displays. It just had to work once with whatever OS and after that it outputs fine all the time.
If you ahve the same problem as above, i'd recommend dual booting another OS, load the proper graphix drivers, get it to output properly once and hopefully it'll fix the problem like it did for my unit.
Thanks for everyone's input with the whole ordeal!
PS. after the initial output, it didn't matter which adapter I used. I kept the generic since it's cheaper, returned the apple one cuz it's exactly the same, and now bought a generic MiniDP - DVI for my at home workstation.
PPS. One final picture of it working....

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.

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?

Mini DisplayPort to VGA Adapter NOT DISPLAYING ON EXTERNAL SCREEN

Hello!
Mid 2012 MacBook Pro
Processor 2.9 GHz Intel Core i7
Memory 8 GB 1600 MHz DDR3
Graphics Intel HD Graphics 4000
Software OS X 10.9.3 (13D65)
I have a mid 2012 MacBook Pro, I have connected a Mini DisplayPort to VGA Adapter in order to watch movies on a HP w19e LCD display.
Ive been using this adapter for a year now and I have never had any problems with it, until now...whenever I connect it to my mac's display turns black, and nothing happens, so I wait and the LCD display shows the unfurtunate NO SIGNAL message, so I wait a little longer and still nothing happens, I unplug the Mini DisplayPort and plug it back in, and nothing happens, and when I say nothing happens I mean nothing happens, my mac's display is black as if it was in sleep mode, I get no signal on the HP LCD and I can't get my computer's display to show image again, the only way to do it is to force restart it.
I looked up the problem and I found a forum with a possible solution for it and did as it said.
1) Restart the computer in Safe Mode with display attached (shut down and restart while holding down shift key).
The display showed up without distortion.
2) Change the display to my desired preferences (dimensions and refresh rate).
3) Restart computer. ...and it works like a charm.
I followed the directions and it worked... but after I restar to go back to um.. normal mode, the problem is back.
Please I need my LCD screen how can I fix this.
I hope I didn't confuse anyone, sorry for my english
THANK YOU

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.

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,
Nathan.

Using Mini DisplayPort to VGA adapter -- any settings on the Macbook Air I need to change?

Going into a meeting with my Macbook Air with Mini DisplayPort to VGA adapter, which will be connnected to a video projector on site. Never tried this setup before. Will this just work or do I need to adjust any video settings on my Macbook Air?

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 Adapter-is it reliable?

I have to give a Keynote presentation with my 13" 2009 mid year Macbook Pro, and planned on using an Apple mini displayport to VGA adapter, to connect to the projector. The reveiws I've read about this adapter are pretty dismal. Apparently, they burn out very quickly or just plain fail to work! How risky is this? What are my options?
Thanks in advance for any advice!

my thunderbolt to HDMI set up has failed a few times. Adapters are gonna fail. I've had great luck with a company called "moshi" They've had great support as well. Hope this helps, cheers!

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.

Mini DisplayPort to VGA adapter difficulties

About 3 months ago my mini DisplayPort to VGA Adapter quit working. It was off-brand. Recently bought an Apple replacement and it is also not working. What is wrong?
When I plug it into the laptop, the screen flickers as it used to, as it prepares to interface with a different display type. Then nothing happens and there is no apparent connection with the projector or TV.
Help!

Perhaps the fault is the cable.
Ciao.

Yes, I can't see why not.
Just give it a try and report back if you have a problem.
