Trying to flip display on vga projector connected to iPad2

Trying to invert display on vga connected projector, but the ipad2 keeps "correcting" it.  Can you lock the display somehow?

I wonder if a DVI to VGA adapter would work on your ADC to DVI connector?
Hazy memory, but I recall seeing comments here that the ADC-DVI-VGA approach doesn't work. Never tried it because I never had an ADC-DVI adapter and now have no ADC port any more.

  • Connecting DVI Cinema Display and VGA Projector from Minidisplay Port

    Hi Everyone!
    I'm trying to get my mid 2011 Mac Mini to send a signal from my MiniDisplay Port to a vga splitter which works fine. My biggest thing is that when I connect my inFocus IN112 VGA Projector the screen shows up from my mac but to connect my Cinema Display it takes VGA so I had to go from the VGA Splitter on one side and use a vga to dvi adapter and my cinema display shows blank? Help Me Please!!
    Thanks,
    Andrew

    I already have a converter on the end of the VGA Splitter to go to the Cinema. The reason I don't use the hdmi to dvi is because with the minidisplay port using vga to the projector and the hdmi going to dvi to the Cinema it makes the projector screen very rough and pixely

  • IPad to vga projector connection questions

    My kids got me a 3rd gen ipad and an apple tv and I would like to do keynote presentations and display them on an older vga projector.  If it matters it would be in a place without internet.  The projector is ceiling mounted with a wall mounted vga connector that is hard wired to it.  I believe the projector can also function as a server for wireless presentations, but I don't know how to wirelessly connect that to the iPad.  To get it working either way would be great.  Any suggestions or  directions would be very appreciated.  Thanks.

    Well I just now looked at the apple reviews of the mini display port to vga adapter to find that many people experience these things not working. Maybe the 3 I have are all dead. I never even thought that all the adapters I have might be defective. All other apple display adapters I have (that are are much older) still work. I have some display adapters that are probably 10 years old that still work great (mini dvi to dvi adapter crica 2004). Anyways I just ordered a new one and will report back after I have a chance to test it out.

  • X230T rotate VGA projector - independen​t monitor driver?

    Hi!  Could not find a clear, definitive answer when searching this issue, so here it is... when using the X230T in tablet mode with the secondary landscape setting and a VGA projector connected using duplicate displays, the projector image is upside down.
    I would like to rotate the VGA image while maintaining the proper tablet features in terms of screen annotations, etc.  So far I have been unbale to find a setting that will allow me to have proper functionality in the secondary landscape setting and the rotated VGA image.
    One forum post suggested a driver that will treat the tablet and the VGA projector as independent monitors, so the rotation does not impact the tablet features.  I have not been able to find such a driver.  The Intel Graphics & Media Control Panel does NOT help since it appears to treat the monitors as dependent (rotating one of them by 180 degrees does not appear to help at all).
    Can someone please point me in the right direction?  Either with the default driver or a OEM driver that I could buy or download?
    The VGA projector is located on the ceiling and shared by different people, so changing the projector settings is not a feasible option.  Help is appreciated.  Cheers!

    I've managed to rotate only secondary monitor in the duplicated-display setting. I used Intel Graphic control panel, and it worked well.

  • HT201177 How to connect my MBP 13" (Mid-2012) to a projector/LED TV using a mini-display port VGA adapter (CAPDASE)

    Hello Sirs, I'm having a hard time connecting my MBP 13" (mid-2012) to my projector using my mini-display-VGA out adapter. But when I switch to Windows 7 (via bootcamp), it can easily be connected... Please help me with this problem. Thanks

    Try connecting the Minidvi to the VGA and connect it all together, first try turning ing on the MBP, then connecting dvi to the the projector. Make sure your projector input is set for VGA. If noo joy invert the affored mentioned proceedure. You should see your image if not, try going to system preferences>displays, click display.   Try readjusting the resolutions in display. reboot monitor.

  • RetinaDisplay MBP not displaying correctly connected to VGA Projector

    I am not sure if this is a Mountain Lion issue or Retina MBP issue
    New MBP.
    hooked it up to a VGA projector tonight ( Apple store folk told me to use the same minidisplayport adapter I used with my older MBP which did  fit the Thunderbolt port.
    Monitor and Mac saw each other but my MBP did not project correct resolution or dimensions
    MBP still seemed to think it was connected to my 27" monitor at home.
    Is this an adapter issue? a MBP issue? a Mountain Lion issue
    Something was amiss
    Any ideas?

    Doesn't work that way with the Retina display
    a)  I never had to select a resolution previously when connecting a VGA projector.My previous Mac auto adjusted its resolution
    b) The preference does not allow choices of resolution as in the past
    Look at how differnt this preference is
    If I chose Scaled I get a few choices of larger or smaler text.
    There may be some options in the main menu bar which Ineed to look at when connecting a monitor ( based on some other posts elsewhere in this Apple discussion area.Dunno... I am sure I am overlookign something  but the old auto adjust is gone, I think

  • Is there a way to predict which video projectors will not work with the 2012 MacBook Air using the Mini-display to VGA adapter?

    I recently upgraded from a 2011 MBA to a 2012 MBA due to the larger capacity SSD.  The 2011 MBA running Lion and Mountain Lion worked with every video projector for lectures.  The new 2012 MBA is hit or miss with video projectors.  It is not an adapter problem.  I have multiple Apple mini-display to VGA adapters with the latest firmware.  They all work just fine with the 2011 MBA. Re-starting the 2012 MBA with the adapter and projector connected has not helped.   
    It it not acceptable to have a laptop that works with projectors some of the time.  Apple is aware of the problem.  Is the only choice to go back to the 2011 MBA? 
    RC 

    I installed 10.8.2 update today with my 2012 MBA.  The details of the update include:  Resolves a video issue with some VGA projectors when connected to certain Mac notebooks.
    I tried using the MBA with a video projector and it found the correct resolution and connected with the projector automatically.  Using detect displays in the disoplay preference pane wasn't even necessary. 
    I hope this is the fix I have been waiting for with the 2012 MBA.
    Thank you Apple.

  • Connecting New iPad (3) to vga projector

    Hi everyone
    Has anyone tried connecting a New iPad (3) to a projector using the vga adaptor?
    From what i've read, most projectors have a resolution of around 1028 x 768.
    What happens if you connect the New iPad, with it's 2048 x 1536 resolution, to a vga projector with a lower resolution? (using the Apple vga connector).
    I would like to show keynote app presentations on a vga projector, but i'm worried that if I use the New iPad (3) that some of the image will be missing?
    Help?
    Thanks

    Does anyone know why the display on the LCD projector is not 1028x768. I have 2 black bands on each side. This is output from iPad3 using the VGA adaptor. It was working fine a day earlier, with 1028.x768. I used another application called Web Presenter and that works fine, with the option to choose external display setting.

    18. What is the maximum resolution available for use with the Apple Mini DisplayPort to VGA adapter?
    The resolution available with the Apple Mini DisplayPort to VGA Adapter is 1920 x 1200. VGA displays that use higher refresh rates (such as 85 Hz) at resolutions of 1600 x 1200 or greater may not generate video properly until you lower the refresh rate.

    How can I detect displays?
    If the detect displays option is not available, hold down the Option key while you are in the Display pane.
    How do I select additional resolutions on my display?
    You can use the Display pane of System Preferences to specify how your display works. Not all options appear for all display models. By default the best resolution for your display will already be selected in System Preferences.
    To select a different resolution, use the Scaled option. Some additional resolutions may be available when you hold the Option button.

    I connect my macbook pro to an Epson wireless projector. The macbook can see the projector wirelessly and the image on the macbook is displayed on the projector. However on system ref., the arrangement tab does not show and thus cannot have multiple view.
    I am trying to project Pro Presenter on the Epson projector such that I have the detail screen on the macbook and only the screen I want people to see on the projector display. This has not been possible because the arrangement tab on the Display section of the System Preference is not showing. If i tried to search for the arangement, it comes back with the message that there is not other source detected, hence the arrangement tab is not showing.
    I have also tried to connect the Epson directly to the Macbook but it still the same result, so its not because it is a wireless connection. Can someone advise me jhow to go around this problem. I have used windows before and it is very easy to extend ptojection on windows, but this system seems to be frustrating to me.

  • Why doesn't my VGA adapter work to connect my iPad2 to my projector. I haven't had any problems in the past?

    Why doesn't my VGA adapter work to connect my iPad2 to my projector. I haven't had any problems in the past?

    Hey MarieF-D,
    Thanks for the question. The following article provides basic troubleshooting steps that may help to resolve your issue:
    iOS: About Apple Digital AV Adapters
    http://support.apple.com/kb/HT4108
    Troubleshooting
    If you encounter an issue using the Apple Digital AV Adapter or VGA Adapter:
    Disconnect and reconnect the adapter from the iOS device and display.
    Connect directly to the TV, projector, or external display using a known-good VGA or HDMI cable.
    Remove any VGA or HDMI extension cables or converters.
    Note that accessories that convert a VGA or HDMI signal to other video formats (DVI, Composite, Component) are not supported.
    Ensure that you are using the latest version of iOS. Some Apple Digital AV Adapters require iOS 5.1 or later.
    Note: When using an Apple Digital AV Adapter manufactured before early 2012 with iPad (3rd generation), you may see the "This accessory is not supported" alert. Dismissing the alert will allow you to use the adapter.
    For optimal performance, you may need to adjust the video resolution or settings for your display. If your display offers an "auto detect" or "factory default" setting, you may be able to use these options to optimize video resolution and display.
    Thanks,

  • Connecting iMac to VGA projector problems

    I have just connected my Mac to a new NEC VGA projector via thundertbolt with thunderbolt-VGA adapter.   Even though I have done evrything that's recommended for the display differences in both the mac and the projector, the image remains poor, blurry, with a overall fuchsia tint.
    What should I do?

    The Mini DisplayPort to VGA adapter is what works in the Thunderbolt Port.
    see > thunderbolt to VGA - Apple Store (U.S.)
    Did you try a different VGA cable like I suggested...?
    Did you try a different Adapter like I suggested...? If not, then take that adapter to your local AASP and have them test it.
