Mini-display not recognizing any LCD

I have an IMac 27-inch OS 10.6.7 Intel-based.  I cannot get the Mini-Display port to recognize any LCD screen.  I have two adapters.  One for VGA and the other for DVI.  I have tried two different monitors with the same results. Neither VGA nor DVI will see the monitor (which displays the "no signal found".  Both monitors work on a PC laptop.
Any help be appreciated.

Morning kirstenpolley,
Thanks for using Apple Support Communities.
If you know the hdmi cable is good.
You may want to try a different input channel or a different display adapter.
For more information on this, take a look at this article:

    First open iTunes (version 11). Then connect the iPad. Now is it recognized?

  • My imac is not recognizing any external dvd writer drive. I have imac with Core i7 and Mac OS 10.6.8. I have tried external dvd writers from Samsung and Amazon Essentials but the computer does not recognize any of them. Which Dvd writer is compatible?

    I have an external firewire burner; it never shows on the desktop unless I insert a CD or DVD - that icon will then show (if I have my preferences set to show those on the desktop). Hae you checked in Disk Utility (Applications > Utilities) to see if it is listed under drives?

  • Yoga Pro 2 - Display not recognized in windows (Driver or Hardware issue?)

    Out of warranty by a month!
    Yoga Pro 2 - 256gb, installed new wireless card a month ago. Windows 8.1
    The touchscreen still works while the screen is black.
    System restarted after sleep mode I think.
    The Lenovo logo is displayed, seems to load windows, but when windows loads (I don't see it load so this is an assumption) the screen blanks and the black light is on.
    I can connect an external monintor which will connect after a return from sleep mode(odd). Which then turns the backlight off.
    When on the external monitor the internal display is not even recognized by windows.
    When I boot in safe mode, the internal screen works fine with of course limited capability.
    I have reloaded display drivers from the support site.
    Right now my internal monitor is not recognized by windows and is dark, and I can use an external monitor.
    Anyone have any clues as to what my be going on? Hardware, driver etc???
    What information can I provide?
    Solved!
    Go to Solution.

    This is a pretty weird issue with conflicting observations.
    1) Screen works in Safe Mode but not in regular boot. (So, not hardware issue)
    2) Display works on external monitor in regular mode. (So, not drivers issue)
    Did you install the wireless card yourself? Did you unplug the display cable while installing the card?
    Could you re-open and check that all connections are good?
    Is the Wi-Fi card working well?
    I would also recommend a complete reset of the laptop to eliminate the possibility that this is a corrupt driver. You can use the NOVO button to reset your laptop. Make sure to make a backup on external drive for your personal files.

  • Desperate...Premiere not recognizing any video

    Hi everyone!  I'm obviously very desperate if I'm posting to a forum for help. 
    The problem is my clips won't show in the timeline. When I drag and drop the video file, every single thing I've read online states that it should AUTOMATICALLY separate my video into clips for editing, and an audio track. It should read "Video 1", "Video 2," "Audio 1", etc. In the default setting, before a video is added to the timeline, it reads "Narration" and "Soundtrack." But, as I said, when I drag and drop a video it is supposed to automatically change. Even YouTube tutorials have shown this.
    Well...mine doesn't.
    When I drag and drop a video, not only does it NOT separate the video and audio, but it doesn't even separate it into clips. The words "Narration" and "Soundtrack" remain on the left side, where it's supposed to read "video" and "audio." So it's as if the program is not recognizing my video file.
    Fine, so I tried another video file. One of those sample ones that were already on the computer. No dice, it still did the same thing.
    So I'm at an impasse. No help sites or anything I've found have addressed the problem of the program just NOT WORKING like it's supposed to! And I know exactly what it's supposed to look like, because it's not that dissimilar from Windows Movie Maker which I have used before.
    Any help would be greatly appreciated.

    It's not from a camcorder, it's an .avi file directly from my hard drive.  Saved on my desktop, no less.
    Two things here:
    AVI is but a wrapper, and so very much can be inside that wrapper. See this ARTICLE for some background, and also tips on how to peek inside that wrapper.
    Second, I would not use the Desktop for your Assets. It is basically a special folder and one with special properties. Often, PrE (and many other programs) will have difficulty accessing the Desktop folder, due to those special properties. Just create a New Folder (or use the My Documents>My Video folder), and Move your AVI file(s) to that. This should be done, with PrE closed. When you Open that Project back up, PrE will ask you, "Where is file _____.avi?" From the Finder, just navigate to that New Folder, or to the My Videos folder, and choose that "missing" file.
    This might also be a good point to talk a bit about what a Project file (PREL file) really is. This ARTICLE will give you some background. It will also explain why PrE asked "Where is file ____.avi?" once you Moved it.
    Good luck, and for a very good starter set of articles, I strongly recommend Steve Grisetti's Basic Training Series at Muvipix. To go beyond those articles, he has some great books on PrE, also at Muvipix.
    Good luck,
    Hunt

  • Thunderbolt display not recognized

    i got this 27 inch thunderbolt. connected it to the imac (11,2 ) but somehow the display is not recognized. doesn't turn on. any ideas?

    I follwed the instructions:
    1. plugged in the power cord from the monitor to the wall outlet
    2. plugged in the mag MagSafe Power cord from the monitor to the Mac Book Pro
    3. Plugged in the Thunderbolt cord from teh monitor ot the Mac Book Pro
    4. Chose Apple icon> System Preference and click displays
    There is no "Arrangement" tab as indicated by the manual.  the monitor is totally black as if there is no power.  But the orange/green light on the MagSafe power cord is on.
    I have undone and redone these steps several times, with the same result - a black screen.  It is a Mac Book Pro 7.1
    Any ideas?

  • IPod mini does not restore - Any advice?

    My iPod mini is frozen, after switch on, on the Apple logo.
    Doing many resets do not change anything. Battery is OK.
    I have tried restores, but the iPod is not recognized, when connected either through firewire, or USB, on 2 different MAC iBooks.
    All tricks given on Support page have been tried (the 5 R method), to no avail.
    Any tip or idea welcome.
    This iPod mini is itself an exchange for a previous mini that had battery problem, and is less than 4 months old!!

    "the iPod is not recognized, when connected either through firewire, or USB, on 2 different MAC iBooks."
    Given the above statement, I would say it needs replacing again. As a last resort, try this from an Apple troubleshooting article.
    In rare cases, iPod might get into a state in which it needs to be drained completely before it can be reset. If iPod didn't turn on after you reset it, follow these steps:
    Disconnect iPod from all power sources and leave it disconnected for about 24 hours.
    Reconnect iPod to the Apple iPod Power Adapter or computer and reset it."
    After that, try the restore again.

  • Anyone have a problem with the HDMI port suddenly not recognizing any digital source imput signal?

    I have an HP 2711x monitor. 
    Anyone suddenly have a problem with it no longer recognizing any digital source input with the HDMI port (or DVI), yet the VGA port works fine?
    Thanks.

    I understand you are having issues with your HP 2711x Monitor not displaying HDMI or DVI inputs, yet it can display VGA inputs. Are these inputs all coming from the same device?

Are there any messages displayed on the monitors screen when you have the HDMI or DVI hooked up?
    Check to see if any of the documents below pertaining to the HP 2711x Monitor pertain to your issue:
