Monitor flickering blacks out jolting MacBook Air and LG Monitor IPS277l

Hello everyone. Using MacBook Air and LG IPS277L and have had no issues up until today. All of the sudden my monitor goes blurry and shuts off. I dont see the little mirror box thingy available at the top of my desktop either. It's like the Macbook isn't sending a powerful enough signal to the monitor or something.
The monitor works fine with 2 other laptops. Tried display settings no luck. No updates from LG for Mac available at this time. Any suggestions?
Thanks....

Howdy iMWorks,
It sounds like the issue you are experiencing is only happening on your external monitor, but the video works fine on your internal display. I have a couple of thoughts as to what could be causing the issue here. First, use these troubleshooting steps to help troubleshoot the hardware, and PRAM:
Apple computers: Troubleshooting issues with video on internal or external displays
http://support.apple.com/kb/HT1573
Try unplugging the video adapter or cable and then plug it back in.
If more than one video adapter is in use (or "daisy-chained"), troubleshoot by using only one adapter.
Example: A mini DisplayPort to DVI adapter connected to a DVI to HDMI adapter is an unsupported configuration because there is a series of adapters in use.
If available, try using a different display and or adapter (or use a different connector by using DVI instead of VGA, for instance).
Reset the system
You can reset the Mac's parameter RAM and SMC.
Reset the resolution
Start by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
Start up in Safe Mode.
From the Apple () menu, choose System Preferences.
Choose Displays from the View menu to open the preferences pane.
Select any resolution and refresh rate that your display supports.
Restart your computer.
If the issue persists, I would use the following article to troubleshoot the Safari application on the computer:

Thank you for using Apple Support Communities.
Take care,

  • Random Black Screen Flash Macbook Air and Apple LED display

    So I have started to see an issue with the new Macbook Air and my Apple LED 24" display. Randomly only maybe 2-3 times a day the screen will go black and then quickly come right back, like a blink. Anyone else see this behavior? This does not happen with the internal built-in screen on the MBA. Feels like a driver or software issue to me.

    Hi Steve,
    I have the same model you've mentioned. Although my issue is not the same, at times when I open my laptop up, I have a black screen, and have to manually power-down. I can tell the keys still work, as I use the brightness buttons and can tell the contrast is getting higher.
    Also last night my keyboard/trackpad stopped working, however the power button did bring up the shutdown options but the trackpad still did not work.

  • Trying to Figure Out Options - MacBook Air AND iPad?

    I've been thinking about this every since Jobs announced the new MBA's, but thought I'd turn to more experience brains here for some help. I'm trying to sell my Late 2008 MBP 15.4" on Craigslist in order to get a new 13.3" MBA with 2.13GHz process and 4GB RAM. The confounding thing is that I also have a 64GB iPad (WiFi only).
    Here's my dilemma: should I just sell my MBP and get the MBA? Side note, I've gotten ZERO response to my Craigslist ads If I do buy the 13.3" MBA should I also try to sell my iPad? For some reason, I feel like having a MBA and an iPad is too duplicative and unnecessary.
    Any thoughts and opinions would be very helpful. Thanks!

    I sold my nearly 3 year old MB on craigslist in the Seattle area for about what the website above said it was worth. I had a buy almost immediately.
    I've also sold several laptops on eBay and mostly got about what I was looking for. On Craigslist, there are a lot of Nigerian scammers trolling. So my craigslist listing clearly states for a reply from me, they have to include their local telephone number. I find this generally weeds out the Nigerian scammers.
    Never had a problem on eBay with Nigerians. Of the two services, I prefer craigslist because I seem to get a better price for my computer equipment. I do include a "money back" limited time period (usually a week) and I've never had anyone ask for their money back. However, I think it reinsures them in case the computer might have a problem. IF I have any defects, I list them upfront.
    Another negative with eBay is the raising fees they charge. To equal a craigslist sale, I guessing you have to get $25-$35 more just to break even.

    Great tip Stephen!!
    I was so frustated from this issue that I used to use Windows iTunes for mass editing info, adding Lyrics etc and then transfering songs to Mac. This tip has alleviated my pain!!
    Thanks for the tip. This question should be tagged as answered.

  • I am out of space on my Macbook Air and have a Time Machine Backup. I want to complete reset my mac, but wonder if I can pick and choose what I restore to my computer? Can I also use my time machine backup and external storage as well?

    I am out of space on my Macbook Air and have a Time Machine Backup. I want to complete reset my mac, but wonder if I can pick and choose what I restore to my computer? Can I also use my time machine backup as external storage as well for the files I don't need everyday?

    If you are using "Restore from Time Machine Backup" option from OS X Recovery, you can only choose from the broad categories presented.
    ... Can I also use my time machine backup as external storage as well for the files I don't need everyday?
    To be clear, if you are asking if you can use the volume containing your Time Machine backup to store additional, non-Time Machine files, the short answer is yes.
    It's not a good idea though, since the Time Machine backup will eventually fill all available space, after which it begins to remove old, "expired" backups to make room for newer ones. The presence of additional files doesn't change that fact, and Time Machine will not erase them, but you will encounter a dilemma should you want to store additional files on that volume when there is no remaining space. You will have to make room for them on your own, by deleting existing files. Furthermore, since Time Machine cannot back up its own volume, those additional files will not be backed up by Time Machine.
    The easy solution for what you describe is to purchase additional external storage. External USB hard disk drives have become very inexpensive; about $55 will buy a perfectly suitable 1 TB drive.
    You can also choose to replace your MacBook Air's internal storage with a larger capacity one. Look for a suitable replacement from OWC / MacSales:

    That gets a little more expensive but it is the optimum solution.

    Use the trackpad to scroll, thats what it was designed for. The scroll bars automatically disappear when not being used and will appear if you scroll up or down using the trackpad.
    This is a user-to-user forum and most people will post on here if they have problems. You very rarely get people posting to say there update went smooth. The fact is the vast majority of Mountain Lion users will not be experiencing any major problems with the OS, or maybe with apps which are not compatible, but thats hardly Apple's fault if developers don't update their apps.

  • This is my 3rd macbook air and pro that kicks me out my yahoo email all the time and tells me my password is wrong when its not this been going on 2 years 3 different macs sometimes it dont do it for months after a software update

    Don't switch email providers. Switch to another email client on your Mac. It is not Yahoo. I have 3 Yahoo accounts and never have any problems getting or sending mail from/to those accounts. But I don't use the built in Mac Mail program. I use Thunderbird. I use thunderbird on both Mac OS X and Windows. Been using it for some time now with no problems getting my Yahoo mail, Google gmail mail or form my work email account.

  • I own an iMac and a Macbook Air and I have iWorks on my iMac. Can I copy it to my Air so that I can use it while working out-of-town? It would not be used on both computers simultaneously.

    I own an iMac and a Macbook Air and I have iWorks on my iMac. Can I copy it to my Air so that I can use it while working out-of-town? It would not be used on both computers simultaneously.

    It depends on how you bought iWork (no 's').
    If you bought a single-user retail box or license from the trial, no, you cannot legally install it on another Mac.
    If you bought a family pack retail box or licesnce, you can install on up to five Macs in your household.
    If you bought it from the Mac App Store, you can install the apps on as many Macs that you have by opening the Mac App Store & clicking on Purchases. Enter your Apple ID & click install.

  • Hello everyone i have macbook air, hello everyone i have macbook air and my startup disc is full i checked everything and and find out that all space is of OTHER and i dont know what is it and what i have to do with that

    hello everyone i have macbook air, hello everyone i have macbook air and my startup disc is full i checked everything and and find out that all space is of OTHER and i dont know what is it and what i have to do with that

    First, empty the Trash if you haven't already done so. Then reboot. That will temporarily free up some space.
    According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation. You also need enough space left over to allow for growth of your data. There is little or no performance advantage to having more available space than the minimum Apple recommends. Available storage space that you'll never use is wasted space.
    If you're using Time Machine to back up a portable Mac, some of the available space will be used to make local snapshots, which are backup copies of files you've recently deleted. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as "Backups." The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself.
    To locate large files, you can use Spotlight. That method may not find large folders that contain a lot of small files.
    You can more effectively use a tool such as OmniDiskSweeper (ODS) to explore your volume and find out what's taking up the space. You can also delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one.
    Deleting files inside an iPhoto or Aperture library will corrupt the library. Any changes to a photo library must be made from within the application that created it. The same goes for Mail files.
    Proceed further only if the problem isn't solved by the above steps.
    ODS can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To see everything, you have to run it as root.
    Back up all data now.
    Install ODS in the Applications folder as usual. Quit it if it's running.
    Triple-click the line of text below to select it, then copy the selected text to the Clipboard (command-C):sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
    Launch the Terminal application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
    Paste into the Terminal window (command-V). You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
    The application window will open, eventually showing all files in all folders. It may take some minutes for ODS to list all the files.
    I don't recommend that you make a habit of doing this. Don't delete anything while running ODS as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means. When in doubt, leave it alone or ask for guidance.
    When you're done with ODS, quit it and also quit Terminal.

  • I have a MacBook Air and for what ever reason, the print settings have gone out of whack. I am not sure how to set to print a normal A4 paper size or a standard envelope. These settings were working O.K., but not now

    I have a MacBook Air and for what ever reason the print settings for envelopes and normal A4 paper size changed from printing correctly each time I wished to print. Now, each time I wish to print either, I have to rest paper size and or Envelope vertical or horizontal. Can anyone assist with how to reset in order to print correctly without the need to rest each time please?

    Log in to the Developer forum. You will find instructions on how to install the lastest beta. Your problem is the beta you have installed has expired. All of them did on October 5; you will find hundreds of threads discussing this. If you have a beta it is assumed that you will continue as a beta tester, so a simple update using iTunes will not work.
    If you no longer want to be a beta tester install the GM 7.0.2 by restoring from iTunes using DFU mode.

  • MacBook Air and Mac Mini Combination

    I am trying to decide between a new (rumored to be out soon) MacBook Pro 15'' or a MacBook Air. If I take the latter option, I will need an accessible hard drive onto which to offload my photos, videos, and other large files. Would the combination of a MacBook Air and a Mac Mini work well for this? Could I use the MacBook Air essentially as the monitor for the Mac Mini when I am using its hard-drive? Are there any other drawbacks or compromises I should think about? Thank you in advance.

    I'm going to agree with tele_player!
    If you're looking for an external storage solution, for the same cost of the Mac Mini you can get a 1.0TB Time Capsule. If you're looking for a computer to pair with the MBA, for the sake of disc sharing and such then the Mac Mini is a great option. But if you're looking for a machine to serve as a data storage unit, then it's definitely not a good choice.
    External hard drives range from 5GB to 1TB, get something that fits your needs. The cost of a 250, 320 or 500GB are extremely reasonable.
