Mac 27in Displays flickering with browsers

I have two 27inch Thunderbolt displays connected to a Macbook Air.
When I bring up browsers, the screen within the browser flickers, especially with video. This happens on Chrome, Safari, and Opera. This happened with Mavericks, and is still happening with Yosemite.
Any suggestions?

This seems to be solved with installation of Yosemite 10.10.2

  • Mac Pro display flickers with a white screen and then display closes

    Hi,
    The display on my Mac Pro started showing a white screen and flickering.
    So I tried formating and re-installing 10.4.10. I am able to complete the installation of first DVD without flickering. But when after the restart after installation using first DVD then the flickering resumes.
    Any idea what is the issue and how we can solve this issue.
    The AHT test shows this code 4 SNS/1/40000001:ICAC. According to
    http://support.apple.com/kb/TS2081?viewlocale=en_US the code should have a trailing number - but my report does not have any number. Is this error code fine? If no, can some one tell me what is the error in the system?
    Thanks,
    Ed

    Same symptoms here. We tried AHT on a good Mac Pro with the video card from the bad mac, and got the 4 SNS/1/40000001:ICAC error. Looks like a bad video card.

  • HT4199 Mac Cinema display interfering with WiFi connection

    Year-old MacBook Pro works fine with WiFi UNTIL I plug into my older Mac 21" Cinema display - which I need to do via Rocketfish adaptor, and a female firewire adaptor. Plug in - offline. Unplug - back online.
    I have messed with network settings repeatedly, and got things running for a small pocket of time. Restart the day after, back offline.
    Note that my older MacBook Pro running Snow Leopard doesn't have this issue - only the new computer, which requires the adaptors to do so.
    Any help is greatly appreciated - this is killing productivity!!!

    Actually, Niel is half-right. After searching for over a month, and researching all sorts of options that "might" work, I went with the Atlona Dual-DVI to Mini DisplayPort (see link above - discontinued so you'll have to look on Amazon or eBay) and the Apple Nvidia 6800 GT DDL video card (look on eBay for approx. $70-$100).
    To achieve full native resolution on the Apple 27" Cinema LED, (2560x1440), you'll have to have both a Dual-DVI to Mini DisplayPort converter/adapter (like the Atlona), IN ADDITION to one of the higher-end "build to order" video cards like the Nvidia 6800 GT DDL or Ultra DDL which can support resolutions greater than the stock 1900x1200 on a single DVI-equipped stock card that came with most PowerMac G5's.
    Hope this helps clarify a little for those looking to stretch the lifespan of those bastardized G5's. ;)

  • Mac mini display flickers after update to 10.9.5

    It's very annoying especially in Safari when i try to scroll my page. I've tried SMC restrat and NVRAM reset, also HDMI disconetion and changing display resolution wont help with this problem.

    Thanks for Your help guys:) And dozens of replys:) If somebody will have simillar problem I can only say that after clean reinstall to 10.9.4 everything works as brand new. I highlly advice not to upgrade to 10.9.5 if You have mac mini with intel HD 4000 and external HDMI display.
    One more time thanks fro Your help and many replys:)

  • T61 LCD display flickering with big patches of black and going to dark (very low light) afterwards

    I have a T61 which has Intel graphic card. It is seven years old and at times has a noisy fan.
    Very recently it started to have problem with its LCD, it starts with slight flickering of light intensity from corners of screen, here and there, eventually covering the whole screen, goes away and comes back, happens for few seconds, the pattern repeats for few times, then big (screen-wide) patches of back starts to cover the lower 1/4th, one-half, 3/4th of screen, flickering between the screen content and black screen, till they cover the whole screen after 30-60 seconds. At that moment, the screen is very dark but with a close look, it is still possible (but very hard) to read it. Connecting it to external monitor (through its VGA), it is working very well. Showing same screen on both LCD and external monitor at the same time, the picture on external is solid, but picture on LCD can have this issue. At the moment of writing this message, the problem seems to not happening!! but it was happening during the past whole week including few minutes ago. I searched online and here in the forum and read few posts, and found about these issues:
    - some T61's have Nvidia GPU and thermal effects over the time and stress on the package or solder balls can make loose connections (this is probably not my case since the interface to graphic card is by Intel)
    - problem with LCD itself (it is working fine just right now)
    - problem with graphic card (it is working very well over the VGA to external monitor)
    - problem with the ribbon from mother-board to LCD (tilted the screen in different angles when the black patches and flickering are happening and didn't change the chaos much in any direction of making it better or worse)
    - problem with bulb inside the screen (maybe the cause, but somehow decided for the last few minutes to working fine)
    - problem with inverter (don't know yet what this part it)
    - problem with some sort of mechanical part(s) being loose, gently tapped on sides and back of the screen while the phenomena was happening and again didn't have much effect on it in any direction.
    I appreciate your time and good gesture of help, many of you would know more scientific/engineering ways of approaching the problem and how to root cause it. My sincere thanks beforehand.

    >  the screen is very dark but with a close look, it is still possible (but very hard) to read it.
    That sounds like a defective CCFL backlight or inverter.
    >- problem with bulb inside the screen (maybe the cause, but somehow decided for the last few minutes to working fine)
    A CCFL is essentially a high intensity fluorescent bulb. One failure mode is flickering.
    >- problem with inverter (don't know yet what this part it)
    The inverter is a power supply that converts the low voltage DC used in the rest of the ThinkPad to high voltage to drive the CCFL. I would expect that to fail catastrophically rather than cause flickering.
    What to do?
    CCFLs backlights are relatively inexpensive ($10 to $15 on eBay) but they can be difficult to replace because they're delicate. You may prefer to replace the entire LCD panel assembly or even the entire top cover assembly (which also includes the inverter card.)
    The Hardware Maintenance Manual for the T61 provides detailed instructions for doing this sort of stuff if you'd like to see what's involved and decide what you feel comfortable doing.

  • New Mac Pro display issues with Thunderbolt display

    When connected to a 27inch Thunderbolt display after a while I get vertical blue lines on the display. If I plug my Macbook Air into the screen, after a while the blue lines clear. How do I find out if it's the Mac Pro or the Display?

    Thanks Turbostar, that's exactly right, it takes about 30 minutes having the Air plugged in and the stripes disappear.

  • How do I connect a mac cinema display to a dell laptop with VGA output?

    I need to connect my coworkers Mac Cinema display to his Dell Laptop with VGA out, running Windows 7. We have a VGA to DVi adapter, but it doesn't work. Do we need a different adapter or a driver? Thanks.

    DVI-I offered by most computers has support for up to a wider-than-1920 Digital display AND a complete set of VGA signals in it.
    If you have an adapter from DVI [computer] to VGA [display] it has no conversion logic in it and should be called a VGA extractor. It will NOT work the other direction.
    I think what you need is a better computer or a worser (VGA) display.

  • Studio Display 21" with Mac Mini?

    I am considering getting a Mac Mini as an economical upgrade to my B/W G3 system but I want to make sire that my monitor is going to work with it. I have the origingal blue and white 21" Studio Display. the System Profiler says this......

    Will this display work with a new Mac Mini? I really do not have the $ right now to get a new Monitor and this one works great anyway. I am also wondering how my current software,,,,,,, Photoshop,Indesign etc. will work with the new Intel Macs?
    THanks for any input

    Can't help on the screen much - believe you need to get an adapter, as the previous post indicated. You might check in the Apple dislay area at http://discussions.apple.com/category.jspa?categoryID=111
    Regarding your applications, as long as you're not running under OS 9 or earlier, your applications will run on the Intel mini under Rosetta emulation. Universal applications are those that have been modified to run on both the PPC and Intel macs, and they run natively. Those applications that have not been made universal run under Rosetta emulation. Photoshop is an example of an application that has not been made universal yet (supposed to happen this year with Photoshop CS3). Running under emulation does extract a performance penalty, of up to 50%, versus running in native universal mode.
    If you have applications running under OS9 or in the OS X classic environment, you'll need to upgrade to an OS X version in order to run on the Intel-based mini, and you may find there are Universal versions of your software, which would be even better.

    How do I enable TDM?
    Make sure both computers are turned on and awake. 
    Connect a male-to-male Mini DisplayPort or ThunderBolt cable to each computer.
    Press Command-F2 on the keyboard of the iMac being used as a display to enable TDM.
    Note: In Keyboard System Preferences, if the checkbox is enabled for "Use all F1, F2, etc. keys as standard functions keys," the key combination changes to Command-Fn-F2.
    How do I exit TDM?
    To leave TDM, press Command-F2 on the keyboard of the iMac that is in TDM. You can also exit TDM if you shutdown or sleep either computer or detach the cable.
    Can I use a third-party keyboard or older Apple keyboard to enable TDM?
    Some older Apple keyboards and keyboards not made by Apple may not allow Command-F2 to toggle display modes. You should use an aluminum wired or wireless Apple keyboard to toggle TDM on and

  • Display Problem with my Mac Pro and LG Flatron Wide Monitor in Mountain Lion

    After upgrading to Mountain Lion, my Mac Pro has display problems with my LG Flatron display.  The image is displayed with a black bar on the right and on the bottom.  And the left side of the content is not visible.  I tried every resolution available in the Display System Preferences, they are different in terms of how big the black bars are, and what part is not visible, but none of them are correct.  I held down the option key to try to detect displays or switch to resolutions that are not normally available.  When I restart the image is lined up with the display, but if the display ever goes to sleep or gets turned off, the image reverts to being off center, and the only way I can get it back is to restart...  The interesting thing is that this monitor works fine with the same machine if I reboot using BootCamp into Windows 7.  The Monitor also works fine, connecting the same connector to a Mac Mini, although that mac mini is running 10.6 and not Mountain Lion.  I've reset the SMC and restarted countless times, I don't see any other levers to pull or things to try...

    That card is for a PC it may not give you Startup and Option-Boot screens.
    The 7950 "Mac Edition" card has a very distinctive look:

  • Facing "Display Flickering" problem with my 15" macbook pro(A1286)while swapping the desktops and closing the tabs.....need help...reply soon

    Suggest Solution for this Display Flickering problem ....

    Hi, I read the post about calibration and I probably do that a little too often TBH! As I get so little time out the battery and mainly use my MBP on my lap, usually with the power supply near by, it gets charged to full, run to empty to the point of sleep, or sometimes it even cuts out and then is recharged to full again, so I really think it's new battery time. I've seen non Apple Official ones for between £35 and £65 that have 3 year warranties and state they are around 5200mh but am unsure due to reviews.
    Later...
    Anyway's I have now ordered a non Apple replacement from Amazon for about £35 and it has several good reviews and 4.5 out of 5 stars so I'll see if it works and report back. If it doesn't I'll send it back and get the Official Apple one.

  • Will my LED 27 Cinema Display work with the new Mac Pro?

    Will my LED 27 Cinema Display work with the new Mac Pro?

    Mini DisplayPort (like 27" LED Cinema Display) is a direct subset of ThunderBolt (like Mac pro late 2013). It plugs right in and the display portion "just works", no adapters required.

  • Is there some secret to getting Pentax K-3 .dng files to display thumbnails when importing to an iPad (mini w/retina)? Files import fine, but no thumbnail. Mac OS has compatability with those files.

    Is there some secret to getting Pentax K-3 .dng files to display thumbnails when importing to an iPad (mini w/retina)? Files import fine, but no thumbnail. Mac OS had compatibility with those files added long ago. Am I missing something?

    I agree Terrance. However, I was able to copy other large batches of other files (my music for example) without any issues. The issue only showed up when copying iPhoto's library and/or the photos themselves. This was repeated 3 times; I copied all my other files to the drive then it unmounted on iPhoto. And, as I said, again when I started with a fresh reformat and just iPhoto. That does not seem like hardware to me if it is only happening with one set of files.
    I have managed to get the iPhoto library to work on my other external drive. It wanted a rebuild twice and a thumbnail rebuild once. I am now attempting to copy it over to the new HGST internal drive.
    Anyone have a suggestion for alternatives to iPhoto? I have aperture, maybe I will try that. But from what I understand, it just shares the same library as iPhoto.
