Occasional flicker on external display

I have connected my Macbook Air to the bluray player of my home cinema system that is connected to my TV.
This allows me to use my TV as external display.
It works pretty well, except that my TV screen occasionally flickers on an irregular interval. Usually 1-10s apart.
The flickers can be described as horizontal screen wide grey/whitish bars or complete screen encompassing bars that appear for a split second
How can I fix this?
This is my setup:
                         1       2                             3
MacBook Air ===> ===> Bluray Player ===> TV
1: mini displayport to hdmi adapter
2: HDMI cable
3: HDMI cable
MacBook Air:
MacOS 10.8.5
13-inch
Mid 2012
2 GHz Intel Core i7
8 GB 1600 MHz DDR3
Intel HD Graphics 4000 512 MB
Bluray Player
Samsung HT-F5200
TV
Samsung UE32F5505
Additional info:
When connecting my macbook directly to the TV, bypassing the bluray player, this phenomenon does not occur.

Digital or analog audio out from the bluray to speakers?
Either way they make a analog or digital switching device for same that lets you select import source
TV into switcher.....and bluray same.....then either digital or analog out to speakers
However a digital switcher will cost more than an AppleTV would, and with the AppleTV you can forego all the wires, however there is still the speaker system which would need to be addressed.
Even HDMI from Apple TV to the HDMI port on the bluray theres an obvious video processing conflict not allowing same. Ive tried same thru my Bluray experimentally and got the same just to test it 10 mins. ago on a LG 60" HD TV thru a Sony Blu Ray player.   'No dice' 
If you only need the DISPLAY off your macbook Air, why not just do Airplay WIFI from your macbook to an AppleTV set?    Unless I assume audio is so important that youre playing youtube videos maybe thru same and need the upgraded audio from the speakers ONLY HOOKED up currently thru your bluray.
Its all wires and more boxes isnt it
Aside from the audio feeding dilema, AppleTv solves the rest of it with ease.
*** I forgot to mention or think of it, but if its an ANALOG speker system, you can get a dual connector for the back of the TV and BLURAY OUTPUT and connect / disconnect same as either can go to speaker OUTPUT and switch back and forth very easy.    $20 cost.

  • 10.9.2 Flicker when External Display is Inactive

    After upgrading to 10.9.2, my 27" iMac starts to flicker (1 sec black, 1 sec normal, 1 sec black) every 10 secs.  It only occurs after the iMac is restored from sleep mode and the external HDMI (via DVI connector) monitor (Sony 4K Bravia) is powered on, but it's PC input is not selected (like watching TV)
    On a fresh iMac bootup, it is OK.   When the external monitor is powered off it is OK.  When the external monitor PC input is selected and showing the iMac's screen it is OK.  With the DVI connector disconnected it is OK.
    This didn't occur with 10.9.1 version of OSX.

    Determined it only occurs if the external Sony display has not been configured by the WindowServer.  Seems the WindowServer, every 10 seconds, tries to detect the external monitor, then blinks once, shows only the iMac monitor as configured and then blinks one more time and shows both the iMac and Sony external monitor.  The repeats every 10 seconds.
    Once the Sony external monitor has had the HDMI/PC input selected, then the WindowServer must correctly see the monitor's settings and stops trying to configure the monitor and the blinking stops.
    Is there a fix for this, as it didn't occur with 10.9.1?

  • My phone keeps displaying a white screen with the apple, then occasionally flicks to a blue screen, but won't turn on! HELP!!

    My phone keeps displaying a white screen with the apple, then occasionally flicks to a blue screen, but won't turn on! HELP!! I have had it on charge all day and have tried plugging it in to my computer to sync.

    Restore your software using iTunes.
    Turn your device off and connect your cable to the computer, but not the device just yet. Start up iTunes. Now, hold down the home button on your device and plug it in to the cable - don't let go of the button until iTunes tells you it's detected a device in recovery mode. Now you can restore to factory settings.
    You should be able to restore your backup file after this procedure. If the problem comes back, you either have corruption in your backup file, or a serious hardware problem that should be looked at by a tech at the Genius Bar (make an appointment first).

  • Macbook pro retina 15" mid 2014 external display flicker randomly black

    external display: Acer k272HUL 1440p display.
    tested ports: Hdmi, Mini displayport, displayport, thunderbolt to HDMI,
    situation: The monitor goes black randomly and recover after several flickers.
    workaround: I have a external gpu connected by thunderbolt to pci-express. The monitor works normally with external graphic card.
    This is internal graphic card problem, it's independent of which port I am using to connect the external monitor. The problem happens on 1440p monitor. 1080p works fine. The problem happens on maverick and Yosemite.

  • My led and external display flicker a lot. What to do?

    I have a late 2011 MacBook or 15". My MacBook screen/display flickers excessively making the mac completely unusable. I am not sure if flickering is the right term. Some times it flickers and some times turns turs completely blue or black with white horizontal lines on it. This happens once a week and I have to reboot more than 20 times to get this solved.
    Same thing happens to my external display monitor which is connected via thunderbolt cable. So this makes it clear that the LED of my Mac is not damaged. I have searched a lot on the forums but couldn't find a solution. If somebody could help me I shall be grateful.

    Here are the Images, which show what happens to my screen:

  • Coverflow causes external display to flicker when rotated

    Hi,
    I have a new MBP 15", 2.2GHz, 2GB with Leopard installed, and I have an external monitor (a Lenovo Thinkvision L201p) which can be rotated into portrait mode, and that is how I use it almost all the time.
    The problem I have is that whenever I browse something using coverflow, be it in the Finder or in iTunes, the external display flickers (sometimes quite badly) as the items move. This happens even if the application that is using coverflow is on a different space (for example, if I have iTunes on a different space and it switches to a different song). It only happens when in rotated mode, in landscape mode the flickering goes away.
    Does anyone have any ideas what could be causing this? Maybe an issue with the video driver? Can someone reproduce this?
    Thanks.

    This was solved in 10.5.3.

  • Problem with external displays

    I've an issue with my MBP 15'' Early 2013. Recently I'd the GPU problem and my logic board was replaced. Everything worked fine as usual but I never tried to connect it to an external display.
    When I first connected a projector after the logic board change via a VGA adapter I wan unable to make it work, the computer had one of this two problems:
    Screen goes black and nothing works
    Computer gets too slow and I can't do anything but move the cursor
    Then I tried with a TV via HDMI and everything worked fine. I tried then with an external monitor, another projector and a TV with VGA and nothing worked.
    I searched in internet and most of the people has this problem with both VGA and HDMI. But I didn't found anyone with only the VGA problem.
    I tried resetting the PRAM, changing resolution to all the available ones and nothing worked.
    Before the logic board was replaced the external displays worked great.
    Any idea?
    Thank you!

    Hey, I had something similar happening with my i5 going to a Dell U2410, but my connection was via HDMI. When I got that distortion however I could not recover from it and had to reboot my laptop. I switched to an analog connector & noticed the occasional flicker to black, almost like my cable was loose and got bumped, but it recovered fine each time. I'm testing now with a dvi cable, and so far no issues *knock on wood*. Sorry, no fix, but maybe try a different connection and see if it improves things for you.
    Cheers!

  • How can I use an external display with my MBP lid closed and disconnected to power?

    I know that I can use an external display when my MBP lid is closed and it is connected to power. I was wondering why it does not work when the power cable is removed.
    I only use an external display when I am at home so my MBP acts like a Mac Pro or Mac Mini in that way, but it is not good to leave the battery charging constantly on a MBP so I want to disconnect the power and use external display and have the lid closed. Is this possible or do I have to leave my lid open when running on battery power?

    I'm plugged into my wall socket at least 90% of the time - probably more. I always make sure that I take my MBP off mains about once every two weeks and let it run down to about 30-40% and then plug it back up. This keeps the ions flowing and the battery healthy. My MBP will be one year old on March 20, 2013, and my battery health is still at 99%. I run in clamshell mode most of the time now - since I bought a 27" Apple Thunderbolt Display. Only occasionally am I off mains - and then because I'm exercising my battery, usually.
    Don't worry about running of mains most of the time - just be sure and unplug about once every two weeks (or twice a month) and let your battery dip to the 30-40% mark and you'll be fine.
    Good luck,
    Clinton

  • External display flashes and shows 'snow'. (Video of behaviour included)

    Since yesterday, my Macbook Pro is acting strange. When I connect it to an external monitor, it usually works. Everything goes well for 10 to 30 minutes, and at some point the display starts tearing, showing snow, and flashing. These flashes get worse and worse, up till the point where I have to reboot. Rebooting seems to help a little. Whenever the laptop hasn't been used for a few minutes it works correctly again, for a short while. (This makes me conclude it's some sort of heat-related issue)
    The issue is present on multiple monitors using different DVI cables. I only have one mini-displayport to dvi adapter, so the problem could be there too.
    This problem does not affect the internal display of the macbook in any way.
    Here is a short video showing the behaviour:
    http://www.youtube.com/watch?v=4BotUqHb3dM
    What should I do? Try to figure out wether it's the mbp or the connector or just bring it in for a repair. (It's less than a year old)

    I have had similar issues with my 15" MBP. Occasionally my external monitor will go 1980s and display what looks like crappy tv reception.
    Also, connecting or disconnecting an external display (via the single link mini display port to dvi adapter) has a tendency to lock up the entire machine (both displays black, won't respond to keyboard or mouse) until the power is cycled.
    Also, my built in monitor has a habit of flickering/glitching lines.
    These problems seem to happen regardless of which graphics card is active.

  • Incorrect resolutions for 16:10 external displays, unable to detect 16:9

    Hey there all, this is my first post here. It looks like some people have had similar issues—particularly with an incomplete/incorrect list of resolutions being provided for external displays.
    I am shopping around for an external display for my MacBook (my specs are included) and I tested a few different ones today, but encountered problems.
    - On a 22" ASUS monitor (sorry I don't have the model) using Mini-DVI to VGA, the native resolution (I assume 1680x1050) is not available, and most resolutions offered are 4:3 ratio (1600x1200 worked). The highest widescreen resolution listed was 1280x768.
    - Next I tried a 19" ASUS, this time 16:9, but the monitor would not display at all. The MacBook display would go blue as normal but then flicker, as if it could not detect the display. This also happened with a 24" BENQ monitor (also 16:9).
    Wondering whether or not this was a problem with using VGA, I then bought a Mini-DVI to DVI adapter and tried again on the 19" and 24" (the 22" ASUS did not have a DVI-in) but the same flickering blue screen appeared, with nothing displayed on the monitor.
    These were my thoughts:
    1. My firmware is not up-to-date. I check in System Profiler and am running Boot ROM Version MB41.00C1.B00 and SMC Version (system): 1.31f0. These are definitely up-to-date for my model MacBook.
    2. Drivers are out of date. This does not seem likely as I am running OS X 10.5.7.
    Other than that, I am at a loss! I haven't yet forked out the $49 to do phone support with Apple, that will be my next bet.
    Has anyone had this problem, or have any ideas what I can try? Short of buying a new Unibody MacBook of course .
    Thanks guys, hope you can help. Just let me know if you need more info about my computer.

    It's unusual to strike out like that with three different monitors using two different adapters. On the other hand, with all the video issues that have been reported by others on these forums since the 10.5.7 update, it's not too surprising.
    Is a 10.5.6 downgrade a possibility for you? For example, do you use Time Machine and can you in that case revert to a previous time when the MB was running 10.5.6? Perhaps that's not a great suggestion, but it would be something to try.
    There is some remote chance, though somewhat unlikely given that three different monitors are involved, that the embedded display driver data (EDID) in each monitor is bad or incomplete. If you care to investigate that possibility, there is a program called SwitchRes X that allows you to snoop a monitor's EDID and turns it into a human readable text file.
    One final suggestion would be to try yet one more monitor to see if any monitor can return a good result. One obvious choice would be an Apple monitor. If there is trouble when trying to connect to an Apple monitor, then that would certainly point to some problem in the MB's configuration or hardware. And not to cast aspersions on the brands you have already tried, but try another brand (if not Apple) that is perhaps more mainstream and known to be more Mac compatible and less firmly in the PC camp where plug-and-display drivers have never mattered very much and are very often botched by the monitor makers. Dell, Samsung and LG are three big brands that come to mind. Good luck.

  • External Display Flickering/Blanking out on Windows 8.1 Boot Camp

    OK, so I have a MBP 15" Mid-2012 model running the latest versions of Mavericks and all software and drivers on Windows are up-to-date. I am using my external display through an Active HDMI adapter for Mini DisplayPort/Thunderbolt (one that broadcasts audio as well as video).
    So, this adapter and image seems to work perfectly fine on the Mac side, however, when I flip the switch to Windows 8.1, the external display goes haywire and goes blank and flickers with occasional lines and static across the screen. Image comes back every few seconds and then will suddenly lose signal.
    I've been reading around the internet and I've seen that this could be a hardware issue in that Intel never put support for Thunderbolt/Mini DisplayPort on their chipsets for Windows, not a driver issue.
    How screwed am I? If not so screwed, what steps do I need to take to attain functionality of the external display while running Windows 8.1 through Boot Camp?
    Note: my Mac does not come with an HDMI port already installed like current Macs. This was the last high-end Macbook Pro to have an optical drive installed on it.

    On a later rMBP, I can connect three displays via TB at full resolution.
    One suggestion is to try a Display-miniDP cable, instead of a converted HDMI signal, if the monitor will accept a DP connection.
    If it works correctly on the Mac side, it would be a driver issue, since the hardware supports it with one OS, but not the other. The effects you describe indicates that some pins on the HDMI are not getting correct signals to maintain image refresh rates or pixel sync. When you use the current connection, does the Control Panel -> Displays detect the model and name correctly? If not, the EDID detection is failing.

  • IMac cannot handle Mavericks and external display?

    I am a long-time apple-user and long-time user of this wonderful forum. This is, however, the first time I have needed to ask a question of my own having been unable to find an answer on here or elsewhere. In fact, I haven't read of anyone experiencing the issues that I am.
    I recently purchased a second hand Apple iMac "Core 2 Duo" 2.0 20-Inch (Al) to replace my old white one. I understand that this is the oldest iMac to be able to handle Mavericks, but I have upgraded the RAM to 4GB just to be safe. I also bought myself a lovely HP W2207H Monitor that is HDMI input and, when on Snow Leopard before my upgrade yesterday, was a beautiful extended desktop with no issues whatsoever.
    Since upgrading to Mavericks, the monitor has not been working properly; but it's not any of the other, well-documented issues that I have read already. The monitor doesn't flicker, it is recognized beautifully and the resolution is spot on the native...
    Right now, for instance, the monitor is working fine. However, if I was to open a new Firefox tab, or open a new application on my iMac, the monitor would go black (not to sleep or shutting down as the light remains on) for two seconds or so. It seems as if the iMac is struggling with doing something and therefore cuts the monitor feed whilst it's doing the process I have just requested. Furthermore, the iMac's fans are running quite hard despite activity monitor showing the decreased usage as Mavericks promised!
    For your information: Apple iMac "Core 2 Duo" 2.0GHz 20-Inch (Al) 4GB RAM connected to HP W2207H by Mini-SP to HDMI adaptor and HDMI Cable.
    I wonder if anyone could help me solve this problem on Mavericks, or will I simply need to regrade down to Snow Leopard for optimal performance of the external display?
    Many thanks in advance,
    Mike

    hey.. the display starts up with the imac...
    I'm having trouble adusting the brightness on my cinema display...
    hopefully get a answer today.. I have a 24" imac

  • External display flickers for a fraction of a second

    Hello all,
    Im using a macbook pro 15 with the new invidia 8600m graphics, hooked up to a cinema hd 30 inch display at home and a HP 30 inch display at work.
    At times, maybe twice an hour, my external display will flicker for a fraction of a second. I can not find a source of the problem, having tried all available graphics drivers from apple and forceware drivers from laptopvideo2go.
    The problem does not seem to be related to any particular action in vista, like opening windows or applications. It just flickers at any given time, for a fraction of a second and then comes back to normal.
    I have tried all available drivers. Yes, UAC is off. TMM is off, too. Yes, it does the flickering on both my cinema hd and the hp 30 at work. Yes, it is very very annoying.
    Anyone else having the same problem? Any idea of what it might be?
    Message was edited by: peterternstrom

    I have but the problem is still there. Matt on this forum has the same problem. He is in Austria, so maybe there is issue with streaming ATV in 50hz countries.
    Will try to connect the ATV directly to my projector instead of going through the receiver.

  • Softproof in Lightroom and Photoshop on external display not matching

    Hi,
    When I soft proof an image in Lightroom (5) and in Photoshop (CS6) on my external display there is a noticeable difference between the two proofs.
    This is the case both with "simulate paper & ink" on and off (with matching settings in both applications) and with a variety of different profiles being used. On my laptop screen the proofs always match (between Photoshop and Lightroom).
    On the external display with soft proofing off there is an exact match between images in LR and PS. With soft proofing on saturated areas of images (particularly reds, greens and yellows) become noticeably less saturated and blocked up in LR as compared to PS. Subdued colours appear to match. It's almost like they are both using the same profile but Lightroom is squashing it into a smaller gamut. I'm fairly sure PS is correct and LR is the one with something going wrong.
    I'd like to sort it as I'd prefer to soft proof in Lightroom as that's where I print from. I've read up a lot on colour management and can't find a solution.
    Can anyone help?
    Thanks,
    Tom
    (I'm on a Macbook pro running 10.8.4 and the external display is an NEC Spectraview 271 (euro version of PA271W), the display is calibrated and profiled with Spectraview 5, with an i1 Display Pro. Working space in PS is Prophoto RGB and it's set to preserve embedded profiles. I've checked with various test images but mostly been using Bill Atkinon's printer test image. I set up the image in LR and PS to match on screen position and with the same colour (white) background, I can then flick back and forth and there should be no change but there is and it's very obvious.)

    I'm having trouble with Lightroom 5 soft proofing with reds too.  To rid my propossed print of a gamut warning I must totally desaturate or change my paper profile to glossy (or both).  This is odd because my monitor is calibrated, I'm using the correct paper profiles etc and when I ignore the gamut warning my prints are looking good. This isn't helpful to you but at least your not alone....

  • View contents of external display on main display (PIP-style)

    I occasionally connect a TV to my MacBook Pro to watch movies and TV shows.  The problem is that I cannot see the TV from where the computer is located.  The computer must stay in this location in order to remain connected to the external HD and A/V receiver.  I'm looking for a way to monitor what's on the external display from the main display so I can more easily drag and position windows onto it.  Sort of like having a small picture-in-picture style window in the corner.  I don't believe this is possible natively, but are there any third-party products that could achieve this?
    Thanks in advance.

    None that I have ever heard of.
