Canon projector doesn't recognize the macbook pro with OSX lion using Mini DisplayPort to VGA Adapter

for some reason my MBP and my iPad do not work with a Canon LV-7390 projector in the conference room at my office.
they work every other place but in this projector (the most important). any ideas

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:

  • 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?

  • 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?

  • Pressing D on boot to get into Diagnostic mode doesn't work. Macbook Pro with OSX 10.6.8

    My charger has stopped working all of a sudden for my MacBook Pro. I tried my friends charger and it works. I've seen a few people mentioning that their charger started working again after running a Diagnostic test at boot up by pressing "D" after powering up the computer.
    I see this instruction all over the web, but it doesn't work for me! I have the OSX DVD in the drive. Holding down "C" while booting makes it boot on the DVD, and holding the Option key will give me a boot menu. But it just boots normally while holding down "D".
    Am I missing something?

    Press D during startup
    Start up in Apple Hardware Test (AHT).
    Apple Hardware Test is included on the DVDs that are shipped with some Macintosh computers. If the copy on your hard drive becomes unavailable, use the DVDs to run Apple Hardware Test.
    For Intel-based Apple computers that shipped with Mac OS X v10.5.4 or earlier, Apple Hardware Test is located on the Mac OS X Install Disc 1 and should be included with your computer.
    For Apple computers that shipped with Mac OS X v10.5.5 to 10.6.7, Apple Hardware Test is located on the Applications Install Disc 2 and should be included with your computer.
    For some Apple computers that shipped with OS X Lion, if Apple Hardware Test cannot be found on the hard drive, an Internet-based version starts up instead.

  • My Macbook Pro wont play sound through Mini DisplayPort to HDMI adapter on toshiba television anymore. The sound plays through sony or samsung television, but not toshiba television.

    I have a Macbook Pro early 2011 running on mountain lion version 10.8.2. A while back, i purchased a mini display port thru HDMI port so i could watch dvds on my toshiba television. it all worked great for a while, then the sound just stopped working. At first, I thought the mini display port connector must have broke, until I plugged it into a sony television and it worked. I also tried using it through a samsung television and it worked just fine. Why does it not work through the toshiba television anymore? The picture works fine, but the sound does not come thru the television anymore. My mac is set to play sound thru the HDMI port and it doesnt. When i switch it to built in internal speakers, the sound comes thru my mac, but when i switch it, no sound comes out. Any help would be greatly appriciated. Thank you!

    I am still waiting to receive a response from them, but i dont think they'll be much help. the television still works fine and all of the ports on the back, including both HDMI ports, work perfectly.

  • I cannot get both monitors to work when connecting my MacBook Pro to a VGA monitor using Mini DisplayPort to VGA Adapter

    Need help with 2 monitor set up on MacBook Pro.

    I am sorry for the confusion.  The reason I asked about the speaker bar is that I can't find any information that shows built-in speakers on your monitor.  I have looked everywhere, including in the HP specifications.
    Here is the Back I/O panel (Input / Output) for your computer:
    Figure 2: Back I/O panel
    1 - Video Graphics Adapter port
    2 - USB 2.0: 4
    3 - RJ45 Network (LAN)
    4 - Audio: Line in
    5 - Audio: Front speaker/Line out
    6 - Audio: Microphone in
    The way that I have always connected speakers is to the port labeled # 5 (Audio: Front speaker/Line Out).  This port allows sound to be sent to speakers.  The VGA port is for video only.  There is no audio capability.  The only connection that sends Audio and Video is the HDMI (High-Definition Multimedia Interface) connectors.
    This is the type of connector that I would expect to see coming from your speakers:
    The male one at the bottom of the picture.
    Please check the monitor carefully to assure that there are actually speakers built-in.  I just don't want us to continue fighting a problem that doesn't exist.  There may have been some incorrect information in the advertisement that you read.

  • 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.

  • How long can the Mini DisplayPort to VGA Adapter last?

    Hi,
    I've been using Mini DisplayPort to VGA Adapter (genuine) for a year now but not everyday. Yesterday I bought a new display that needs this adapter, so now is the time that it will be used everyday. I was wondering how long can it last (or operational hours) if it were to sit in the same place, not unplugged, with an average use of 4 hours a day?
    Thanks
    PS. This one: http://store.apple.com/us/product/MB572Z/B/mini-displayport-to-vga-adapter.

    This is impossible to predict.
    Sometime cables last a lifetime, sometimes they fail in short order.

    You didn't mention any color calibration being done on your monitor.  This is an essential part of any color-correct workflow.  What are you using to calibrate your monitor (and your printer)?
    Print profiles (for soft-proofing as well as printing) are for specific combinations of paper & printer.  The nine you have are each, most likely, for a common paper (perhaps mfr'd by Canon) to be used with your printer.
    I don't know what you mean when you say "I choose a high standard print option".
    Have you read the User Manual chapter on printing?
    Printing Your Images
    There is also a good appendix on calibration:

    Precisely why it's not an iPad, and why it doesn't cost very much.  An Apple rep would tell you how to connect an iPad to every computer.

    Likely because it's a not self contained and/or it's game and copy protected, so install it via the developers instructions instead, which likely means it will have ot be uninstalled off the first machine, the developer contacted for a new license key before installing on the newer machine.
    If you want it on both machines, you will need to likely buy another license.
    Most developers are fine with transfering license between machines, you have to contact them.
    They just want to make sure it's only on one machine so they are not getting robbed.

    See below if the search engine setting was changed without your knowledge and you can't change it back.
    You installed the "Genieo/InstallMac" rootkit. The product is a fraud, and the developer knowingly distributes an uninstaller that doesn't work. I suggest the tedious procedure below to disable Genieo. This procedure may leave a few small files behind, but it will permanently deactivate the rootkit (as long as you never reinstall it.)
    Malware is constantly changing to get around the defenses against it. The instructions in this comment are valid as of now, as far as I know. They won't necessarily be valid in the future. Anyone finding this comment a few days or more after it was posted should look for more recent discussions or start a new one.
    Back up all data. You must know how to restore from a backup even if the system becomes unbootable. If you don't know how to do that, or if you don't have any backups, stop here and ask for guidance.
    Step 1
    In the Applications folder, there may (or may not) be an application named "Genieo". Genieo may be partially installed even if this item is absent. If it's present, select it and open the Finder Info window. If it shows that theVersion is less than 2.0, download and install the current version from the genieo.com website. This may seem paradoxical, since the goal is to remove it, but you'll be saving yourself some trouble as well as the risk of putting the system in an unusable state.
    There should be another application in the same folder named "Uninstall Genieo". After updating Genieo, if necessary, launch "Uninstall Genieo" and follow the prompts to remove the "newspaper-style home page." Restart the computer.
    This step does not completely inactivate Genieo.
    Step 2
    Don't take this step unless you completed Step 1, including the restart, without any error messages. If you didn't find the Genieo application, or if you couldn't complete Step 1 for any reason, stop here and ask for instructions.
    Triple-click anywhere in the line below on this page to select it:
    /Library/Frameworks/GenieoExtra.framework
    Right-click or control-click the line and select
    Services ▹ Reveal in Finder (or just Reveal)
    from the contextual menu.
    If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
    Go ▹ Go to Folder...
    from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
    A folder should open with an item named "GenieoExtra.framework" selected. Move that item to the Trash. You'll be prompted for your administrator password.
    Move each of these items to the Trash in the same way:
    /Library/LaunchAgents/com.genieo.completer.update.plist
    /Library/LaunchAgents/com.genieo.engine.plist
    /Library/LaunchAgents/com.genieoinnovation.macextension.plist
    /Library/LaunchDaemons/com.genieoinnovation.macextension.client.plist
    /Library/PrivilegedHelperTools/com.genieoinnovation.macextension.client
    /usr/lib/libgenkit.dylib/usr/lib/libgenkitsa.dylib
    /usr/lib/libimckit.dylib
    /usr/lib/libimckitsa.dylib~/Library/Application Support/com.genieoinnovation.Installer~/Library/LaunchAgents/com.genieo.completer.download.plist
    ~/Library/LaunchAgents/com.genieo.completer.update.plist
    If there are other items with a name that includes "Genieo" or "genieo" alongside any of those listed above, move them as well. There's no need to restart after each one. Some of these items will be absent, in which case you'll get a message that the file can't be found. Skip that item and go on to the next one.
    Restart and empty the Trash. Don't try to empty the Trash until you have restarted.
    Step 3
    From the Safari menu bar, select
    Safari ▹ Preferences... ▹ Extensions
    Uninstall any extensions you don't know you need, including ones called "Genieo" or "Omnibar," and any that have the word "Spigot" or "InstallMac" in the description. If in doubt, uninstall all extensions. Do the equivalent for the Firefox and Chrome browsers, if you use either of those.
    Your web browser(s) should now be working, and you should be able to reset the home page and search engine. If not, stop here and post your results.
    Make sure you don't repeat the mistake that led you to install this software. Chances are you got it from an Internet cesspit such as "Softonic" or "CNET Download." Never visit either of those sites again. You might also have downloaded it from an ad in a page on some other site. The ad has a large green button labeled "Download" or "Download Now" in white letters. The button is designed to confuse people who intend to download something else on the same page. If youever download a file that isn't obviously what you expected, delete it immediately.
    You may be wondering why you didn't get a warning from Gatekeeper about installing software from an unknown developer, as you should have. The reason is that the Genieo developer has a codesigning certificate issued by Apple, which causes Gatekeeper to give the installer a pass. Apple could revoke the certificate, but as of this writing, has not done so, even though it's aware of the problem. This failure of oversight is inexcusable and has compromised both Gatekeeper and the Developer ID program. You can't rely on Gatekeeper alone to protect you from harmful software.
    Finally, be forewarned that when Genieo is mentioned on this site, the perpetrator of the scam sometimes shows up under the name "Genieo support." He will tell you to run the provided uninstaller. As he knows and intends, the uninstaller does not completely remove the malware.
