MiniDisplayPort-VGA adapter (bug?)

Hello,
I just bought a new MacMini (model last 2009)
I connected trough original Apple miniDisplayPort-VGA adapter to a FullHD-Projektor.
when I play HD-movies bought in iTunes store,
iTunes or Front-row tell me i must connect a HDCP capable Display
(via Analog VGA, that make no sense for me)
I know, that digital output of HD-Movies must be protected via HDCP, (but not analog).
The miniDisplayPort-Adaper was correct recognized in the System-Profiler
with the old MacMini I dont had this problem (with DVI -> VGA Adapter connected)
is there a solution for that? (I think this is a bug?!)
(sorry for my english)

HDCP typically does not work through analog connections, only digital.
You can remove the "typically" qualifier from this statement. HDCP is strictly a digital-only initiative.
HDCP bans compliant products from converting HDCP-restricted content to full-resolution analog form...
Dave, do you have a citation for that comment? It's different from everything I know about HDCP. In fact the consortium of industry, studios and other content producers specifically left analog out of the discussion. AFAIK there is no restriction for, say, a component video enabled device to send full definition HD content out the component video port, even though the content may be protected by HDCP were it to be transmitted digitally. In fact, AppleTV stands as an example of that. It will pass anything purchased from the iTMS out its component output at full definition.
What I think this points to, though I'm only guessing because Apple doesn't tell us such things, is that the Apple Mini DisplayPort to VGA Adapter does not itself possess the ability to provide a KSV, meaning it can't do the HDCP "secret handshake." Hence the DisplayPort on the mini is prevented from outputting any digital HD content to that adapter lest it be intercepted in its unencrypted digital form as it passes from the mini to the adapter.
To the OP, if you instead use the Apple Mini DVI to VGA adapter as Dah-veed suggests, I think you will find things to be working as expected. With this adapter, digital video need never leave the mini's case. The same is not true of the Apple MDP to VGA Adapter because the D-to-A conversion happens within the adapter and outside the confines of the mini's case. That could be the difference.
You should also try Dah-veed's suggestion of updating the FW in the adapter you already have on the chance that it is supposed to be HDCP compliant and that it isn't working right.

HDCP is the Digital Rights Management/copy protection scheme for High Definition media content, and is sent over HDMI connections. Your VGA connection is not designed to carry this information, as it is just an analog signal. You will need to connect your mini via an HDMI adapter, and make sure all the adapters and cable connections are HDCP compliant.

I plug in through the Mini DisplayPort adapter, MacBook Pro screen flickers, and nothing happens with my external monitor.

HT3382 Does the Apple MiniDisplayPort to VGA adapter allow me to connect a VGA DLP projector as a display?

I want to connect my MacBook Pro i7 that has a mini Dsiplay Port/Thunderbolt port. I want to connect it to my VGA NEC LT20 DLP Projector.
I have the Apple MiniDisplayPort to VGA adapter, MB5727Z/A, Model Number A1307 and the computer does not recognize the NEC LT20, nor does the LT20 recieve the MacBook Pro as a computer or other source.
My previous MacBook Pro core duo with DVI to VGA adapter worked fine with the projector.
Is this because the Apple MiniDisplayPort to VGA adapter is only for computer to VGA video displays?
Is there another adapter that will allow me to use my particular VGA proejctor with my MacBook Pro?
Has my replacing the old computer with the newer one forced me to shell out big bucks to for another projector, thereby making my ability to give educational lectures for free to audiences impossible?

When you plug the projector into the computer, with the projector on, dose the computer reconize a second a 2nd display is connected?
ie: Menu bar, click on the Apple menu, chose System Preferences, click on displays, do you see an arragment tab?
if you do see an arragment tab, try clicking gather display windows. a window should pop up for the projector. What resolution is it set to? is there a lower resolution you could set?

Lion 10.7.3: blank screen with MiniDisplayPort to VGA adapter

Updated my Mac Mini to Lion 10.7.3 recently.. now my MiniDisplayPort to VGA adapter signal is gone: screen is black all of the time, immediately after turning on the Mac Mini. I still have video output via HDMI, however I need the VGA adapter at work. Any help how to get out of this ?

Minidisplayport to VGA adapter - no signal

Hi, we have problem with Minidisplayport to VGA adapter. It seems that when we plug it between the netbook and the projector it does not give any sign of life... the port seems to be disabled. Is it possible?

I have the same problem!
I tried connecting my macbook pro 13" (latest generation) to:
1- A data projector
2- An external monitor
none work.
I believe that BLUE SCREEN that flashes when you plug in the cable is simply what happens when the macbook recognizes that an adapter has been pluggged in, and it's trying to send the signal out to another video device. I get that blues screen too, and also get that flashing blue screen when I click "detect display" in the video preferences.
Nothing has worked so far. Apple advises unplugging and plugging back in, as well as putting the computer to sleep and then waking up again. I tried all of that and didn't work. Also tried changing the resolution, and nothing. Will go back to apple store ASAP and see if it's a bad cable.
In the meantime, has anybody had the same problem? Or found a solution???
Cheers.

How to get sound from computer to tv using a MiniDisplayPort to VGA adapter?

Using a Mini DisplayPort to VGA adapter I am able to get my computer screen onto my TV display. However, there is no sound. My MacBook Pro does not have a Mini DisplayPort and a Mini DVI port -- only a Thunderbolt. Is there any way to get my computer sound to go through to my TV output speakers?
Thanks for any assitance.

VGA and DVI do not carry sound. Only HDMI.
Use a minidisplay-to-HDMI adapter. Then when the TV is connected to the system use "System Prefences > Sound > Output" to select the TV for sound.
Or connect speakers to the output port of the MBP.

Mac mini with minidisplayport to vga adapter: display does not sleep

I have a late 2009 mac mini. When using a mini displayport-vga adapter from Apple, whenever the mini puts the display to sleep the video goes black and my monitor goes into test mode (not sleeping).
It's almost like the signal to tell the display to sleep is not passing through the adapter. I have a Dell 2007WFP.
It works correctly with a minidvi-dvi adapter, but I have another computer connected via dvi so I would like to keep the mini on vga.

The dell would not go to sleep, ever.
For anyone else having the same issue, I got it resolved. I got another VGA cable and it now works perfectly. It is possible the cable I was using was older and didn't have a required wire or maybe was broken.

Mini-DVI to VGA or Mini DisplayPort to VGA Adapter?

Hi There,
I am so close to purchasing a new Mac Mini that I can almost taste it. When I finally get the Mini, I want to hit the ground running, so I am trying to research everything out so I do have any stupid delays.
With the Mini, I want to use my 17" Apple CRT Studio Display with its 15-pin miniature D-type connector (I'm assuming that this is the typical VGA display connector). When I first started looking into the Mini, I figured that I could use a Mini-DVI to VGA connector and just be done with it. When I looked at the Mac Mini Accessories page that Apple set up, however, Apple says that I need a Mini Display Port to VGA adaptor and doesn't say boo about the Mini DVI adaptor. Doing some cursory Googling lead me to believe that the most current MacBooks and Minis will not support Mini DVI to VGA adaptors. Is this true?
If you were me, if either adaptor can be used, which VGA adaptor would you use? Is one superior over another? Inquiring minds want to know.
Thank you very much in advance for your reply.
Sincerely,
Malcolm Fuller

Personally, I'm using a minidisplayport to vga adapter I had to pay $30 for and it's working great for me and I can't tell the difference in image quality from the minidvi to dvi cable that comes with the mini.
Also, why not get the displayport so you can run 2 monitors at once?
If the displayport doesn't work with your monitor then I would try the mini-dvi version.
But yeah don't be suprised if you have to mess with it to make it work since it seems to work for some like me and not for others:

Problem with audio and vga adapter in presentations

this is an odd problem. I potted a presentation that contained a qt movie. The video plays with sound just fine via the vga adapter until you plug in an external speaker system or earphone. the sound stops.
if you play a video outside keynote or play the video with out the video vga adapter or just unplug from the audio jack it works fine. am I missing something or is this a bug. For the life of me I can not figure out what the VGA in keynote has to do with audio.
John

Dr. John, this might be a little simple of an answer, but is the video jack pushed all the way in?
I had the same issue with my ipad playing a movie over a sound system and projecting it also, and discovered that the Apple issue iPad cover comes very close to interfering with the audio output jack, and that my plug into that jack wasn't all of the way in.
After that it's worked fine.

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.

DVI-to-VGA adapter disabled on HDMI-equipped monitors?

Can anyone with an Apple DVI-to-VGA adapter on a Core Duo or Core 2 Duo (both at 10.6.8, currently and probably forever) still connect to a second monitor if the monitor also has an HDMI port? I could until early 2011. From 2008 to 2010 I could connect to every VGA monitor through the DVI adapter.
I thought the DVI-out on my MBP died but got a newer MBP and it, too, doesn't work on any HDMI-equipped screens. Both computers and all my DVI-to-VGA adapters work fine on monitors without HDMI. Yes, I rebooted. No, it's not the cables. Again, all components otherwise work in other arrangements. I am not talking about any other setups. The HDMI-equipped monitors all work fine with miniDisplayPort-to-VGA plugs (today!) from newer Macs.
Any work-arounds? Anyone have a best-recommendation on an adapter that works still?

Thanks, BSteely, I have the latest QT and iTunes already. Closing the lid seems to kick the MacBook external display into some special mode that Front Row can't display videos in. For example, you get the Front Row interface, but as you select movies/TV shows, the preview window on the left side is blank. Open the cover, and have both displays going, and you can see the previews fine (and of course, you can see the movies/TV shows play fine as well when you click on them)
Running Quicktime Player full screen works fine without Front Row in either open or closed lid mode. So it is apparently something wrong with Front Row itself.

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.

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.

Mac mini 2009 . Mini DVI - VGA adapter with Monitor LG L1953S . No sleep .

Hi ..
Yesterday i started in the fabulous world of MAC with my brand new MAC MINI . The problem that i have is that when the MAC mini is in stand-by the monitor is not in sleep state , and i get in the monitor screen " check cable " . So i have to disconnect manually the monitor when mac is in sleep state .
I am using mini-dvi to vga adapter (original mac ) .
¿What is the problem ?
Thanks a lot ...

DVI-I provides the direct Analog signals needed to get VGA using a very simple adapter.
DsiplayPort (and its Mini variant) requires a converter to produce VGA or Dual-Link DVI, and the converter must be active/powered. There is a lot of logic in those converters. It may also have additional limitations.
In general, you should hook your highest resolution, most demanding display up with the DVI to VGA adapter.If running two Mini DisplayPort displays, ALL MiniDisplayPort converters must be active/powered.
