Thunderbolt HDMI HDTV issues

Ok, so I have the latest model 13" macbook air with Lion, and when I connect it to my 720p hd tv to watch movies, the display/sound fades in and out. i.e. it works notmally for 10-30 seconds, then blacks out/mutes the audio (coming through HDMI).  I am using the griffin adapter.  Same issue occurs at different resolutions.
The same adapter/computer works fine on my 720p projector (no flickering).
The same adapter/ HDMI cable(tried 2)/TV works fine with my pre-thunderbolt mac book pro.
Same issue with or without audio running through HDMI.
HELP!!!!

When I run my macbook air, via a different thunderbolt to DVI adapter, it works find (but no audio).

  • MacBook Pro does not sense external monitor (Panasonic HDTV in my case) via thunderbolt-HDMI connection...Is update 10.8.3 helping anyone?

    My MacBook Pro (newest model in 2013 so far) does not sense external monitor (Panasonic HDTV in my case) via thunderbolt-HDMI connection...Is update 10.8.3 helping anyone else who has this issue? I returned my multiple HDMI adapters after figuring out it had to be an Apple issue n not the adapters so I can't check it myself now.
    Thanks!

    I have late 2012 MBP 13" and connect to my Panasonic Plasma correctly.
    But using the same cable, can't connect to an LG 47LM6200, the MBP detects the TV, the screen blinks blue, but the TV shows "no sinal detected" message.

  • Issues with Thunderbolt-HDMI connection on Mid-2012 MacBook Pro

    I have a 2012 MacBook Pro (non-Retina display) and just bought a thunderbolt-HDMI connector, but it's not working. A screen appears on the TV, only it's not my desktop screen, but the standard galaxy image in most Macs. Any idea how to fix this issue?

    Your TV is extending your desktop. You can drag some of your windows off of the MBP internal screen onto the TV. You can control how the two screens are related spacially at System Preferences > Displays > Arrangement.
    If you want the two screens to show the same picture, you should turn off "mirroring" on that same setting page.

  • Thunderbolt to TV issues

    I have a macbook pro mid 2011 and Im having trouble with the thunderbolt to hdmi connection. I have a Lg tv and when connecting the hdmi the tv screen flickers and I lose audio for about 3 seconds. This happens about every 10 seconds. I assumed it was a refresh rate problem but i've tried different resolutions ( even the hd ones) to no avail as the signal seems to still cut out every 10 sec.
    The problem doesn't happen when I run windows 7 through bootcamp making me think there is something wrong with lion. I'm running all the latetest updates for the thunderbolt port and i even have tried resetting my Pram and NVram with no result
    Any help is greatly apreciated as I have been searching for a solution for a few days with no success

    Thunderbolt/HDMI Connection Issue Solved for Me
    I have a MacAir, Sept 2011 edition, Part # MC 969LL/A,  running on Mac OS X Lion 10.7.5. On the Mac's partitioned hard drive I use Parallels version 6.0 to run:
    a. Windows XP, service pack 3;
    b. Windows Media Player, version 11; and
    c. Microsoft's Silverlight, Version 5.1.20913.0.
    I recently bought a Kanex 10' Mini DisplayPort to HDMI cable which I connected to my older  Insignia TV, model E228CZNKW1BYNN.
    I connected this cable to my Mac's Thunderbolt outport into the TV's HDMI, opened my Firefox browser, version 24, on the Apple side of my MAC & tried to watch a streaming CBS show of last week's NCIS through the WiFi signal of my home router. My TV screen flashed "Video 5" & turned a medium blue color at the same time that my MAC monitor lost its signal & turned the same color. Nothing happened on either screen , & like others on this forum, I never got the TV nor my Mac screen to display any video or audio.
    We quit trying to work the Mac Apple & connected the same cable to my wife's new Acer Aspire V5 operating Windows 8, Windows Media Player,  & using Google Chrome's browser. We then seamlessly watched our router's WiFi streaming NCIS show directly on the Insignia monitor without any setup or connectivity issues about video or audio -- while controlling the TV with its remote.
    Later I re-connected this cable to my Mac's Thunderbolt outport into the TV's HDMI, opened Parallels, Windowx XP, & took its Firefox browser to the CBS website to watch another NCIS episode. Like on my wife's Acer, we then seamlessly watched the streaming NCIS show directly on the Insignia monitor without any setup or connectivity issues about video or audio -- while controlling the TV with its remote. I then checked my MacBookAir System Preferences & noted:
    The "Display" tab was defaulted to resolutions @ 720p with no "underscan".
    The"Arrangement" tab was defaulted to "mirror display", and
    The "Color" "Display Profiler" was defaulted to "HD 709-A".
    My comparative, non-geek, conclusion of the above opeerations:
    a. My Kanex cable works very well -- and is not the problem.
    b. The Acer (with its AMD Quad Core processor) & Windows 8 and a Chrome browser connected directly & seamlessly to a streaming WiFi signal with no adjustments or tweekings.
    c. The MACBOOKAIR Parallels 6 operating "OLD" Windows XP (SP3) with a Firefox browser also connected directly & seamlessly with no adjustments or tweekings. [The defaulted color brightness, balance, & contrast were all better on the TV through my Mac than though my wife's Acer.] and
    d. The MacBookAir OS X Lion 10.7.5 must be the source of these connectivity problems -- and APPLE fix these problems -- whatever they are!!
    Given my 3 year teck support contract, I'll be calling APPLE soon to discuss the above. If they provide me an APPLE solution, I'll try to post it here later.
    Hopes the above info helps!

  • Picture is blurry when i connect my screen (HP) with thunderbolt - HDMI

    Hi I just bought a new macbook pro 13 inch. I am connecting it to my screen HP 2159m but I cannot get the same picture quality as with my old PC. It is dark and blurry in comparence. I have set it with 1080p 60hz wich is the highest resolution I can find in the settings their is no option 1920x1080 in the setting list. I called apple support but they couldn't fix the problem. I am connecting with thunderbolt - HDMI to my macbook. My PC was connected with DVI.

    I now solved my issue by buying a DVI -mini display port adapter and connecting through my DVI cable to the monitor. But APPLE ...this is not good! you should resolve this issue so it is possible to connect with a HDMI cable.

  • THUNDERBOLT/HDMI

    Why does my thunderbolt/HDMI cable not work on my macpro - for watching what is on my LT on my tv?

    To set the resolution for your display, the Mac sends an EDID request to the display, and the display is supposed to answer with its name and its capabilities.
    The request is sent out only at certain times, and the TV must be set to the correct input and must answer, or the display stays dark. These times are:
    • At Mac Startup
    • System Preferences > Displays ... Hold option key and click (Identify Displays )
    • When the Mac-end of the cable is inserted.
    • At wake from sleep
    If the display is identified, its name will become the name of the window in Displays Prefs for that display, and it will also appear in:
     menu > About This Mac > ( More Info ) > Displays .. and Report > Graphics and Displays

  • Does 1.9 fix the HDMI handshake issue ?

    does 1.9 fix the HDMI handshake issue experienced by users with the Newer 7 series set top boxes? Frankly, that is my biggest desire for this new software.

    In general there ae fewer handshake issues with the 7xxx boxes
    1.9 does include some fixes for some handshake issues.  For motorola boxes it includes new firmware from Motorola as well as Verizon's new IMG.

  • HDMI overscan to HDTV issue on x120e

    I get very annoying overscan when i hook my x120e up to my Samsung UN55C6500 via HDMI. It's fine via VGA, but not via HDMI. CCC has no setting (that I can find) to fix the issue.
    XBMC has it's own overscan correction so it's fine but win7 is very frustrating.
    any solutions?

    Has there been a fix to this problem? I have had my x120e for nearly a year, but just tried to hook it up to my 1080p HDTV via HDMI for the first time. The overscan issue is horrible -- it's not off by just a pixel or two, but by a lot! I'm running the HDTV at 1920x1080 in extended monitor mode, not cloned mode, in Windows 7 64-bit, and I have the latest ATI drivers and CCC per the Lenovo x120e driver page.
    Further, while the ATI documentation claims that it can be adjusted using the overscan slider, there is no such option anywhere in the actual software -- it's as if the help manual and the software are out of sync. I've tried everything I can find in CCC, but no luck. Meanwhile, the HDTV works just fine with my cable box, my Blu-ray player, and my other laptop via HDMI. So this is definitely an x120e/ATI issue, not a problem with my HDTV. I'll never buy another Lenovo with AMD/ATI graphics -- I've had compatibility problems with a couple of them now, but never with Intel graphics. For crying out loud, this is a digital display, not a CRT, so why should any adjustments be needed at all??
    Help! Does anybody know how to fix this? Thanks

  • Need help hooking up HDTV to iMac using Thunderbolt/HDMI on OS Lion

    I have been trying to figure out why my HDMI television gives me a "No signal" message when I hook it up to my iMac. It is the 2.5GHz Intel Core i5, running OS X, version 10.7.5.
    How do I hook this up? I just bought a new TV and the one I had before this, I used to just hook the HDMI cable in from the Thunderbolt port to the HDMI port on the back of the TV and it would immediately just come on. Now I get a "No signal" message when I do it. Is there a setting somewhere I'm missing?
    Thanks.

    Do you have another adapter / cable to test with?
    what about another port on the TV?
    What about trying the old tv?
    you could check the display settings:
    apple menu
    system preferences
    show all
    displays
    arrangement tab (arrangement tab only shows up when the mac detects a 2nd display. )
    gather windows

  • Thunderbolt - hdmi issue

    I used to run my late 2009 15" macbookpro with a mini displayport -->hdmi convertor on a dreamcolor monitor. Running this same cable on a new 15 inch with thunderbolt port to the same monitor produces a far inferior result. The display looks interpolated or something. Any ideas?

    I have been to the Apple store and this is what i found out!
    I had done a update
    MacBook Pro EFI Update 2.1
    and this is what caused the HDMI problem, it is a firmware update so there is NO FIX until they adress it and a new update come out.
    Please can they do this quickly.
    Hope this helps someone not download this update....

  • HDMI HDTV AV adapter issue

    Hello. I am using my iPad Mini with an Apple HDTV AV adapter (HDMI) to mirror my DirecTV GenieGo App which allows me to watch recorded shows. No matter which brand TV (Sharp, Samsung, Vizio, LG) I use it cuts off the top of character's heads when watching. I also tried messing with all TV screen options with no luck. Any help would be appreciated. Thanks!

    Hi Friend,
    The only way to cure this problem is try to find an option directly on the TV that set the image properly. Probably you will not find a way to solve it by your idevice, but anyway, you can try reboot your device and if it not helps, plug on the tv first, change settings to mirror and then back into av receiver.
    Hope it helps

  • Thunderbolt to HDMI audio issues

    I apologize in advance if this has already been asked in some way that I didn't see in my previous searches for answers.
    Why is it telling me this? I have been pushing audio through perfectly fine, then yesterday it started to display this and was no longer pushing anything. Anyone know how to fix? I have changed nothing on my physical display or my prferences to bring about this change.

    I posted a picture on there, but it appears it didn't go through. I shall attempt to get it up again.

  • 13" Macbook + DVI-HDMI + HDTV Problem

    Hello,
    I recently bought myself a 13" macbook, which I'm now in love with!
    so here's my question, I have a Mini Dvi to Dvi Adaptor hooked up to my macbook and a DVI to HDMI cable running to my HDTV (32") into the HDMI Input (on the tv.) When I goto plug it in ( either tv first or macbook first) My macbook screen turns to this hazy blue screen (looks just like the boot up screen) and Then my macbook freezes up. I've tried shutting down my macbook plugging everything in and then booting up, but still no luck it does the same thing. I just got my mac on sunday straight from apple.com .
    any suggestion? I've heard this is a typical issue.
    Thanks
    Aj

    no luck, I made sure the cables were super tight and plugged in properly. my tv says "no signal"
    and my macbook freezes up with the blue screen.
    This time I tried it two different ways, I shut down my mac book and made sure my tv was off. Turned on my tv switched it to HDMI IMPUT 1 and tightly plugged in my cables. then turned on my macbook.
    After seeing the booting screen ( little apple picture and music) a light blue screen (that normally appears durning booting) appears and it freezes on that blue screen. then I tried leaving my mac book on and tv turned on to HDMI Input one and plugging it in, this time I'm able to see my desktop ( on my mac book, tv still says no signal) and I get this fogginess that appears over the screen. I can move my mouse but everything else will not respond.
    any help or suggestion would be super!
    Thanks guys (and or gals)
