MacBook Pro Retina to TV via HDMI

So, I have my MBP Retina and I would like to connect it to my television via HDMI. I have my Mac connected to my TV via HDMI, and it shows the picture, but there is no sound! How do I fix this?!?!?!?!?!?! I need help ASAP!!!!
Thanks, Kynan

Don't worry! I just figured it out! I just had to go under system prefernces and go under sound and go under the output tab and click on the tv!
Thanks for you help anyway!

  • Macbook Pro Retina not working with HDMI

    I have a Mac Book Pro Retina that will not work using the HDMI port. I have tried with two Monitors and difference cable and the issue happens on both. I connected one via a Display Port to VGA and it works fine.
    I'd like to use the HDMI port. I am running Mountain Lion 10.8.4 (Latest Version).
    I have tried deleting the pref panes as outlined in ofther links. Aslo reset pram without sucess.
    Is anyone using a Macbook Pro Retina with builtin HDMI port sucessfully with 10.8.4?
    If you are using HDMI with Display port let me know if I should get an adpater to test.

    Hi walkerheather,
    It sounds like you've already done most of the pertinent steps here:
    Apple computers: Troubleshooting issues with video on internal or external displays
    http://support.apple.com/kb/ht1573
    I would recommend going through once and trying anything you may have missed in the section "No video or no signal, image distortion, 'snow,' or flickering" and then follow these steps from the very bottom:
    If you tried all of these steps for your display and the video issues persist, contact Apple technical support or take your Apple computer to the nearest Apple Store or Apple Authorized Service Provider (AASP) for diagnosis. If you plan to visit an Apple Retail Store, make a reservation at the Genius Bar using http://www.apple.com/retail/geniusbar/ (available in some countries only).
    Note: Diagnostic fees may apply for issues not covered under warranty or the AppleCare Protection Plan (APP).
    Take care,

  • 2 monitors on MacBook Pro (Retina) using Thunderbolt and HDMI ports?

    I would like to buy a MacBook Pro with a Retina display.  I want to attach 2 external monitors and Ethernet.  I need to use one Thunderbolt port to attach to my (wired) ethernet.
    Can I attach 2 monitors to a MacBook Pro (Retina) using
    1) a mini display port to DVI adapter
    2) a HDMI to DVI adapter?

    Yes, it is possible to run 3 monitors at once on the Retina MacBook Pro (2 connected over Thunderbolt and one over  HDMI).
    Displays used in picture below:
    Retina on laptop @ “best for Retina”
    iMac used as a display @ 2560 x 1440 via Thunderbolt
    iMac used as a display @ 2560 x 1440 via Thunderbolt/DisplayPort
    LG monitor @ 1920 x 1200 via HDMI
    Hope this answers your question.

  • Macbook Pro Retina won't drive HDMI out

    So I was talked into the new MacBook Pro Retina in place of a new Mac Pro by the guys at the Apple store.  I told them I needed to drive 4 displays and they assured me the MBPr would do that.  2 from mini display ports.  1 from HDMI and it's own display.  Fair enough.
    Only, the HDMI out seems dead.  I am running two Dell monitors on the mini display to DVI connectors.  I am trying to run a 3rd Dell monitor on HDMI to Disply port but am getting no signal.  None.  Nada.  After a few seconds the monitor tells me there is no signal from the computer and it shuts down. 
    I have seen a lot of other issues around the HDMI output.  Anyone know the status?  Has Apple bugged this?  Is there a fix in the works?
    Thanks!
    Charles

    Try with just the HDMI external; display. I would suspect the HDMO cable if this test does not work. Tray a new HDMI cable. If the new cable does not work, take the computer to an authorized service center. There is no "bug" using HDMI to an external monitor.

  • Macbook pro retina 13 late 2013 hdmi output error during wakeup

    hi
    i got a pretty annoying error while my macbook pro retina 13 late 2013 is connected to a 2nd screen (i set the 2nd screen as main screen).
    it all seems fine when i put the mac into sleep mode.
    when i wake it up, the mac screen shows the background picture and the 2nd screen (still main screen) which should show the login frame, just shows grey/black points.
    solution so far when you want to wake your mac:
    1.) wake it up
    2.) immediately put it back to sleep
    3.) then promptly wake it up again and get your login frame.
    does anybody know how to fix that bug?
    and btw, i got a second problem:
    im running osx mavericks, and id like to turn off the 2nd desktop while the mac is connected to a 2nd screen.
    unfortunately, this works only if you close your mac and it is connected to power supply.
    my momentary solution is to turn down the brightness to zero: problem, the 2nd desktop is still there and my mouse keeps getting lost on it!
    any solutions for that? like you can choose on windows "projector only"!

  • Macbook Pro to Toshiba LCD via HDMI screen shuts off

    I have a mid 2010 model Macbook pro hooked up to a 46'' Toshiba LCD tv using the moshi connector and an HDMI cable. Every 25-30 minutes the screen goes black for 2-3 seconds as well the sound turns off. The picture then comes back, usually to shut off again for 2-3 seconds then will remain on for another 25-30 minutes. This happens each time I connect the laptop to the computer.
    I have returned the TV, connector, and HDMI cables and the issue has continue to happen. This leaves me thinking that it must be an issue with the computer. Does any one have any tips or ideas as to what I can do to stop this? Its really irritating to try and watch a movie to have the picture cut out periodically.
    Thanks

    Hi, Guys
    I'm using a MacBook Pro with a Samsung 610 52" color monitor for studio video production.
    I'm using an adapter to hook up the TV to the Mac via VGA. There are times when I can get the image on the screen, but any time I either start cold or have to change a cable, I get the message "check signal cable." I originally thought the problem was the cable, but changing out three different "known to be good" cables did not resolve. When select system preferences=>displays=>gather windows, the Samsung window with resolution options opens. Nothing as of yet immediately resolves the problem, but if I **** around with it long enough (plug and unplug cables, turn both computer or LCD off and on), eventually I get a picture. And yes, I never had this problem when we were using a Dell Inspiron. Any suggestions or resolutions, please let me know.

  • No sound when I connect my Macbook pro (2012) to TV via HDMI!

    Hi! I have a problem with the sound when I connect my Macbook pro (bought in 2012) to a Phillips HD TV. The strange thing is that it only happens with some videos (specially youtube videos) but the sound works perfectly with films and audio files I have in my computer, and also when I watch TV online (Eurosport player for instance and other similar applications). It's even stranger because it doesn't happen all the time; last week I tried many times to watch some youtube videos and after unplugging the HDMI cable it seemed to work. As I said, with Eurosport player and many films downloaded in my macbook I don't have this problem (sound is ok all the time), and this is why I'm really confused. I suppose it's not a connection problem, otherwise I wouldn't have sound in any video, right? I've tried two different HDMI's cables but nothing has changed. Please, someone help me, as I can't figure out what's happening. Thank you very much!

    Well Im not sure what the fix is for your problem, but can you please open up the sound preference next time you connect the philips tv, and make sure that sound output is set to hdmi out. Then try and play your video's etc and see if they are affected. 
    I can tell you I get a similar problem when, for example, I have a youtube window open and then connect the external display. The youtube video will not sound out through the cable, however if i refresh the window it works. Also the same when I use bluray player on mac, I have to close it and open it again for the sound to output through the external monitor.

  • MacBook Pro - connect to TV via HDMI Mini Display adaptor

    Can't connect macbook pro to my TV and view/listen to what's on my mac on the tv. I am using an HDMI cable from the tv to a mini display port HDMI adaptor. When I go to system preference, display it doesn't have an Arrangement tab to mirror. It only gives me tabs for Display and Color. Any help would b appreciated.

    Hello pdr4d,
    Based on your post it seems you are unable to get video on an external display. The following article may help you find a solution:
    Apple computers: Troubleshooting issues with video on internal or external displays - Apple Support
    Check connections
    When using an external display be sure to check the following:
    If you're using an Apple notebook, confirm the AC power cable or adapter is securely connected to the computer and the cable providing power to the display is also secure. It is always good to have your notebook connected to AC power when an external display is in use.
    Confirm display adapters are fully seated in their respective connections and that they are supported models and for the computer and display. Refer to these articles to assist you with adapter compatibility and further configuration information:
    Monitor and Display Adapter Table
    About Mini DisplayPort to HDMI adapters
    Apple Mini DisplayPort adapters: Frequently asked questions (FAQ)
    Thunderbolt ports and displays: Frequently asked questions (FAQ)
    Remove all display cable extenders, KVM switches, or other like devices and retest to determine if the issue is resolved.
    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.
    Thank you for contributing to Apple Support Communities.

  • MacBook Pro Connect to TV via HDMI with Toslink...???

    So I have a MacBook Pro (Mid 2009) and using a Mini-DisplayPort to HDMI will not give any audio. Only MBP (Mid-2010) I did sum research and found this video: http://www.youtube.com/watch?v=STx9PN7TPoc&feature=related which connects a Audio using a Mini Toslink to Toshlink adapter which is connecting that to a AMP. My question is: If i connect the Toslink to my TV (since I don't have a Amp) Will it still give out audio? I'm a little confused. Any help anyone...??

    To Csound's good advice, let me just add that there may be a specific HDMI port on the TV that you must use if you're going to send audio to the TV separately. This should also be explained in the TV's manual.

  • Macbook pro early 2011 sound via HDMI.

    Hi,
    I own a Macbook pro 13 inch (early 2011) and a liftrons mini display port to HDMI adapter.
    If I connect my macbook to my philips tv it works fine.
    And if I'm watching a photo slideshow using Iphoto I also hear the sound on the tv.
    But when i'm watching a movie using VLC I only get the sound through my macbook speakers.
    Does someone know how to fix this?
    I tried changing the sound settings on my macbook, but nothing works.
    Thanks!

    That sounds like an issue you need to bring up with the VideoLAN group who works on VLC.  Possibly, you might want to go to VLC Preferences and disable Audio, and let the Mac control it, but I'm not sure. 

  • How to connect an early 2009 MacBook Pro to a TV via HDMI

    I have the cables and adapter but am only getting one image when all is hooked up.......what else need I do?
    I've seen youtube instructions but I seem to lack the "arrangement menu under the "displays" preference.......
    Is this MacBook unable to run to a TV with HDMI plug?

    Hi mate,
    Two options - either turn on mirroring in the Displays Preference panel, or have a look at the arrangement section of that panel, you should see the second monitor positioned in relation to the laptop monitor - it's "extending" the desktop - move a window from your main monitor towards the second monitor's relative location as shown and you should see it appear on your TV.
    If you start your movie (DVD player or whatever) in window mode, move the window to the second monitor, then make it fullscreen - it should fill your TV and play there. You may need to muck around with the aspect ratio (16:9, 16:10 or 4.3 depending on your source) to get it right on the second display. VLC does this nicely especially if your source was converted incorrectly.
    Also tick the box to display the monitor settings in your menu bar - it's handy IMO.

  • Connect Macbook pro retina mavericks osx through hdmi philips flat tv goes green

    Heeeelp!
    The sound works and the mirroring works. I can see my screen and everything fine.
    It's just green!
    The entire screen has a very strong green tint. I don't know how to get rid of it!

    Open System Preferences, go to Displays and on your external display, click on scaled under resolution and just pick the proper resolution.
    I have NO idea why this fixes it but it does. Maybe its a driver issue.

  • Hello, I have a Macbook pro retina-2013.  About Mavericks I could set my 4K monitor via HDMI on 2560x1440.  This I can not get through at Yosemite. Can someone help me there?

    Hello, I have a macbook pro retina-2013.
    About Mavericks I could set my 4K monitor via HDMI on 2560x1440.
    This I can not get through at Yosemite. Can someone help me there?

    They really pushed that it would all work great! Has anyone had the same struggle? Are there any step-by-step instructions to get linked up?
    Call Verizon's wireless tech support & explain your problem to them.  They will provide "step-by-step" instructions over the phone. 
    Take notes too!
    TIP:  If you do call & don't want to go through all those darn promps, when you initially call, just don't say anything.  The automatic voice will then say,  "will connect you to a service rep."
