Disable display mirroring _by default_

Every time I connect a projector to my MBP (e.g. to give a presentation), the system defaults to mirroring the display, and I have to manually disable mirroring - in the meantime, half of my windows get resized because the main display has switched resolutions.
I want to set up the MBP so that an external display (e.g. projector) will, by default, NOT mirror, but rather be part of the extended desktop. In other words, I want mirroring to be OFF by default, instead of being ON by default (and having to be manually disabled) as it currently is.
Is there any way to change this default behavior, or am I stuck manually turning off mirroring every time I connect a projector?

Firefox will pick up new plugins from the registry as they are added by other software, so that could explain the origin.
I can't think of a feature native to Firefox to disable new plugins by default, but perhaps an add-on offers this feature??

Lion login always goes back with display mirroring on

How to disable airplay mirroring on iPad with ios7

How to disable airplay mirroring on iPad with ios7?

I've had this problem ever since I was at my friend's house- she has Apple TV- and my iPad connected automatically. So, I have no idea why any of the practical solutions that people think of are not options BUT, in terms of just getting it done, I did figure out a way. The key for me was getting near another Apple TV. I was out of town so I took my iPad to another friend's house who also has TV. Once I was logged onto their wireless network (the same network that their Apple TV is on-- that's how it connected in the first place), then the Airplay icon and options showed up from the bottom-draw menu and I was able to make sure that mirroring was turned off from the Apple TV section and to make sure the selection was on iPad instead. Problem solved. Now whether or not this will stay the same (rather than me having to make sure it stays at this setting everytime I link up to a network that has an Apple TV on it) I don't know. So my advice is find someone with Apple TV and connect to their network with your iPad and then change it.

Mac OS X 10.7.4 ARD Issues When Observing/Controlling Computers with Display Mirroring/Different Resolutions

As if Macs in an enterprise environment could be more difficult to manage, now since our upgrade to OS X 10.7.(4) I have lost the ability to remotely control numerous Macs in our organization. The issue occurs when attempting to control a Mac running OS X 10.7.(4) that has their Display mirrored and the resolution does not match on both displays. What happens is that I can see the remote screen however it does not fill the entire Observe/Control window. Instead, the remote screen takes up about 50% of the window, the rest is black but sometimes will display a mirror image of the remote screen in the black area. What?! Yeah, I've attached a screenshot because this is ridiculous. The real problem is that I cannot control the computer when it has reached this state, the mouse no longer functions properly, it is not clicking where I place the mouse, etc. I have made sure that I have all updates including ARD Client/Server updates. I even tried VNC but as I have come to find out that is a whole other issue (doesn't work, sends me to the login screen, etc).
So here's what I need:
- A patch that is going to fix this issue
- A script to run that is going to change the remote screen resolution (I still have the ability to run remote scripts, etc. simply not Observe/Control)
Ideas?
<Image Edited by Host>

I found a way to work around this issue. Not a fix but a work around.
This is little application some one wrote to toggle mirroring on and off.
Mirror Displays
If you put this application in the client computer's /Aplications folder
you can use ARD or SSH to run the app and switch modes.
The problem only occurs for me when a client is set to mirror dissimilar displays with different aspect ratios.
I am only seeing this in Lion 10.7.4 and 10.7.5
Hope it helps someone....

IMac won't offer display mirroring option when connecting to HDTV with Thunderbolt to HDMI cable

I have an iMac, and am trying to connect to my HDTV to use as a second display (mirror). I am using a cable with a Thunderbolt connector at one end, and an HDMI on the other. I know the cable works because I have used it with my MacBook on other TVs. When I use this on my MacBook, I simply open displays, and between the tabs marked "Display" and "Color" there is always an "Arrangement" tab to select. When I try this same setup on my iMac, the only two tabs I can see are "Display" and "Color" - the option to mirror disdplay (or recognize the HDTV in any way) simply doesn't exist.
I would welcome any help. Thanks much, Doug.

OK, yes your Mid 2011 has a Thunderbolt port.

5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.
6. Release the keys.
Then try connecting the TV to the iMac.

Adobe Reader XI enterprise deploy-disable display PDF in browser?

There appears to be conflicting information about Adobe Reader XI and how to pre-configure the "disable display pdf in browser".
The Enterprise Administration Kit/Guide says you can do this via the MSI Property:
DISABLE_BROWSER_INTEGRATION = YES
However, acrobat help, indicates you can ONLY do this manually via individual browser add-ons.
I have the redestributable version from Adobe and I used the Enterprise Guide to make the AIP and used the Customization Wizard to create the package and am using the properties line when the msi is installed to disable the display
so which one is right?

I am out of the office until 1/22/13.

Disable "Display PDF in browser" | Acrobat, Reader XI

I understand this is the suggested method of disabling the "Display PDF in browser" is http://helpx.adobe.com/acrobat/using/display-pdf-browser-acrobat-xi.html However we would like to know if there is an API or something we can simply remove from the workstation to disable "Display PDF in browser".
Where is and what's the name of the file IE loads for "Display PDF in browser"
Is there a Reg Key that we can modiefy to Disable "Display PDF in browser"?
Thanks in advance for any assistance you might be able to offer.
Ed

From the KB note: "Acrobat XI and Reader XI do not include a preference setting to open web-based PDFs. "
In other words, what you want is already the default. All of the major browsers have their own PDF viewer. Moreover, the old reg pref "disable browser integration" never worked across all browsers due to the number of browsers and the rate at which they were evolving. That pref is removed in 11.x products.
While I don't understand the question in your first bullet, the default browser behavior seems to be what you are looking for. Browser behavior should be configured with browser settings rather than Acrobat/Reader settings.

Adobe Reader DC, doesn't disable "Display PDF Document in the web browser" when option is unchecked.

The option under Accessibility>Setup Assistanct to uncheck the "Display PDF Document in the web browser" doesn't correctly disable Display PDF in browser when unchecked, it still defaults to opening in Internet Explorer even after restarting the browser. Confirmed this tested agianst with IE 8, 9, 10 and 11 with the same behavior. Moving back to Reader 11.0.10 and using this same setting works flawlessly. Anyone else experiencing this issue?

I am out of the office until 1/22/13.

Will the first gen ipad support display mirroring via airplay when IOS5 is released?

From what I have read, IOS5 will support display mirroring on the ipad 2.. Is this likely to be added to the first gen ipad ? If so then great, but if not, why not? Im sure if you can wirelessly stream music and movies to an Apple TV device (connected via wifi) from the ipad one, then surely you must be able to use display mirroring ?

In case you didn't click on the link above that is on the Apple site:
AirPlay Mirroring for iPad 2
Wow your audience in the board room, classroom, or living room. AirPlay now supports video mirroring. Which means you can wirelessly — and securely — stream whatever’s on your iPad 2 to your HDTV via Apple TV. Everyone in the room sees exactly what’s on your iPad display up there on the big screen — even when you rotate iPad from portrait to landscape or zoom in and out on photos.2
So unless you were told be Steve Jobs that the iPad 1 will also do AirPlay Mirroring it really doesn't matter what you have been told, you are posting at best speculation but more likely misinformation.
And no, don't have anything better to do.

Here comes my problem, I cannot disable this function. The button is greyed out is abled.

any idea how to disable the

It appears that the full-screen display will only work on the display that has the menu bar.
You can switch the menu bar to your external display by going to Solid Apple -> System Preferences -> Displays, then Arrangement.
Grab the menu bar and drop it on the icon representing your external display.
When you full screen an app it should then full screen on the Cinema display.
I wish it would just full screen on the display the window is on, but that is evidently not the way it was designed to work.

Toggle Display Mirroring On/Off - alternate methods?

Does anyone know if there is a standalone application or script that will simply toggle Display Mirroring on or off?
Due to a custom setup I'm using, I can't access the menubar or System Preferences to do this.
I found a terminal utility that sort of does this but it leaves Terminal open after completing the task. I don't know how to tell it to close Terminal when done. Anyone know how to do this or how to integrate in to an Applescript that will do this?
Here is the link to the software I'm using: http://eruvia.org/software/osxmirroring/
Thank you!

Let me restate what I think you are saying and asking, just so I am sure I understand; you are using a projector along with the MBP's built-in display so that both are running at the same time, correct? Is this part important to you, meaning do you care that both displays are running or would you be happy to have just the projector running and the MBP's lid closed and screen not running? If that would be OK with you, e.g. just the projector running, then that may be the easiest thing to do to get content displayed on the projector at 1080p full screen.
If you do care that both screens are running, does it matter to you which is the primary screen, e.g. the screen with the menu bar along the top? Because you could set the projector to be the primary screen by moving the menu bar (under the Displays preferences Arrangement tab) and I believe that would also work to have your content show on the projector at 1080p in most cases.
Let me know if any of that makes sense because maybe I am completely misunderstanding the issue.

VIXIA/LEGRIA HF G30 true display mirror?

I know that the HF G30 has a mirror option that, when enabled, mirrors the video image horizontally. Unfortunately, for me as a diver this is only half way useful. I'm using an ikelite dive housing that has a mirror on the left side of the housing so I can see the display from behind while the display is in hinged position, folded to the cam body. For framing my shoots the mirroring works fine.
But whenever I need to change settings and the onscreen display comes up, then the G30 switches to unmirrored display. For ordinary use this is the right thing. But for underwater usage this isn't really helpful as this forces me to use the view finder ... which isn't exactly convenient with a half or full face mask, sadly.
Is there any display mirror option (maybe hidden) that allows me to constantly mirror the display even with all cam information in the screen also getting mirrored horizontally? While divers are probably not so much of interest to Canon I would be more than happy to hear that Canon actually want to help and offer a function that makes using the G30 under water more convient.

You were, just not directly. If you go to apple's mountain lion webpage, you'll see this note at the bottom:
1. AirPlay Mirroring requires a second-generation Apple TV or later, and is supported on the following Mac models: iMac (Mid 2011 or newer), Mac mini (Mid 2011 or newer), MacBook Air (Mid 2011 or newer), and MacBook Pro (Early 2011 or newer).
