MacBook Pro 17 - Mini Display Port to HDMI - No Sound??

The support page from December 15, 2010 mentions "Mini DisplayPort in the latest Mac models enables audio and video output for the latest multimedia standards: DisplayPort and HDMI."
MacBook Pro 17 from Mid 2010. Can someone be more specific as I purchased a MBP 17 in August, connected the Moshi Mini DP to HDMI Adapter with Audio Support that I purchased from the Apple Store and NO sound??

I actually had the same problem as you did, i then selected the sound output to HDMI and it worked. But then the tv always doesnt plays the sound. It percectly works once and then the other time it wont. I checked through the setting, did not work. Lastly i restarted my mac and it worked. so now whenever i have a problem with the sound, i restart my mac. I wish someone comes up with a solution to this problem.

Mid-2010 macbook pro mini display port to hdmi works only intermittently

I have a 13-inch mid-2010 MacBook Pro running OS X 10.10.2. HDMI out from mini displayport to my Dynex TV only intermittently works. The times that I have gotten it to work involves a combination of restarting the computer, unplugging the TV and plugging it back in, then plugging in the MDP adapter. Now when I plug it in, the MacBook screen flashes black like it is trying to detect the external display, but no picture on the TV. Any help would be appreciated.

Here is the console log output when I plug in the adapter:

Macbook Pro Mini Display Port To HDMI Not Connecting To Sony Bravia KDL-52XBR9 And Any HDMI TV's In My House

I have a Macbook Pro (Mid 2010) and recently purchased a mini DVI to HDMI cable. I was using it perfectly fine on my LG TV for a while but than one day I plugged it in and it just stopped working. The Macbook Pro screen would flash blue for a few seconds than return to normal as if nothing was plugged in. I tried detect displays and everything and it sill does not work. I tried it on 4 HDMI inputs on TV's in my house and none of them are working. Does anyone have any idea on what's wrong? I didn't change the settings at all. Just plugged it in than it stopped working. Anyone know whats wrong?

Hi 1,
You are far from the first to experience this issue. An SMC Reset may resolve some video issues, although this scenario is not listed; still, I would try it: http://support.apple.com/kb/HT3964

Mini display port to HDMI make my retina MacBook Pro have strong static

Hi god, every time I use my new Retina MacBook Pro only one weeks old using internal battery connect mini display port to HDMI to my Sony LED TV my MacBook Pro will have will strong static all around the body! If I plug in the Mac adapter the static will be gone! It never happen to my old MacBook Pro 2011 early! Pls help...

If it is the same adapter, then I would bring the MBP and the adapter to an Apple store for evaluation. If not, the adapter may be the problem.
Ciao.

I just ran a software update for Java and MacBook Pro SMC, now my Mini Display Port to HDMI TV is not working. The TV is flickering. The Mac Display is fine.

I was just watching / streaming TV off Safari on my actual TV.
I'm using a Mini-Display Port to HDMI cable for the connection to the external display.
Software update popped-up and said there was an update for Java and for SMC.
I ran the update and upon the computer restarting, my external display (my TV) is no longer working. It is now flickering.
It won't work in Mirroring or set up as an extended display.
I've reset SMC / PRAM / Safe Mode / Even restored from a Time Machine backup (From before the updates were done).
What could it be?!

I keep saying this over and over, in the hope that people who do a search will find it. Apple cannot possibly test for or be reponsible for the bazillion combinations of adapter, cables, and TV's out there. The only monitors that are 100% guaranteed to work with the MacBook Pro are the Cinema Displays and Thunderbolt Displays, because, they're made by Apple. They're expensive, but they work perfectly.
My guess is that you bought a cheap MDP to HDMI cable, or have a defective one. From my reading of these boards over the past few months, cheap cables have a high failure rate. And the regular priced ones have only a slightly less of one. Try a new one. Make sure you do not damage the Thunderbolt port.

I am trying to connect my MacBook Pro to my TV with a mini display port to HDMI converter. Its not working. Any suggestions?

Depends on your model TV. Read your TV user manual. The newer models have "how to hookup" instructions for computer & games.
You can also do a forum search as well as a Google search.

How can I play music on my macbook pro (OSX Lion) through a Pioneer receiver. I've connected them with a mini display port to HDMI cable with audio support bought at the Apple Store, but there's no sound coming through. thanks

How can I play music on my macbook pro (OSX Lion) through a Pioneer receiver? I've connected them with a mini display port to HDMI cable with audio support bought at the Apple Store, but there's no sound coming through. There are 4 HDMI-in ports on the receiver - BD, DVD, DVR/BDR and audio. In my system preferences for sound, the receiver doesn't show up as an output option. Can anyone please advise. (ps, this is my first time posting a question, so I hope I can find your answers!) thanks, JP downunder

For sound, try the audio output port and connecting to the RCA audio input ports on your Pioneer receiver. Use something like this:

Help using a mini display port to HDMI cable with MacBook Air and TV

Hi, Apple gurus. I need help setting up my MacBook Air to my Vizio TV using a mini display port to HDMI cable that I just purchased on Amazon.
And here's info about my MacBook Air:
In the Amazon reviews, someone posted the following how-tos, which aren't working for me:
1. Plug in both ends, mini display port on your macbook and the HDMI on any available port on your LCD.
2. Go to upper left Apple menu and scroll down to system preference. Or use your FINDER from the dock, go to applications, then system preference.
3. Click on Displays
4. Click on DETECT DISPLAY
5. A similar screen pops up with name of your LCD, mine says SONY LCD, click on ARRANGEMENT
6. Click the box that says MIRROR DISPLAYS.
7. Go back into system preferences and go to SOUNDS which is located under HARDWARE.
8. Click on OUTPUT, then select HDMI, which should be listed next to your LCD name.
I ran into trouble at step #4. My MacBook Air doesn't list the option of "detecting display." I do, however, have the box mentioned in step #6, "Show mirroring options in the menu bar when available."
Regarding step #8, HDMI didn't appear in the list — I only see "internal speakers."
So, what am I doing wrong? Or, did I buy the wrong cable?
Thanks in advance for your help!

Or you need to get an appropriate adaptor. The Griffin adaptor sold on Apple's Online Store will work with a standard HDMI cable.

I have a Macbook, 13" screen, purchased in 2007. I want to hook it up to my HDTV; I purchased a mini display port to hdmi adapter but it does not fit. Any suggestions?

If you connect yourMacBook using a MiniDVI/HDMI adapter you will need to use external speakers for audio since the pre-2010 MacBooks will only send video through the MiniDVI or MiniDisplay Port . The MiniDVI/HDMI doesn't carry audio and there's no audio plugs on the TV to work with HDMI since it's expecting audio with the HDMI.
If your TV has a DVI input plug you can use a MiniDisplayPort/DVI adapter. Then a DVI cable to the DVI input plug on the TV. The TV will have RCA audio plugs for use with the DVI. Plus DVI gives a sharper image than HDMI.

Mini-display port to hdmi cable not working consistently

I have a MacBook Pro (15-inch, Early 2011) 2GHz Intel Core i7, 4GB, Intel/ATI combo video - Yosemite 10.10.2. I purchased the monoprice 15" mini-display port to hdmi cable and it worked perfectly for about 1 month or 2. Now when i plug in the cable, the MBP doesn't detect that I have a second display connected at all. I assumed the cable died so I tested it on my iMac. The cable worked. Also when I try my Monoprice 15" mini-displayport to VGA cable, that works on my MacBook Pro. I can't figure out what is causing my MacBook Pro to "forget" how to detect this cable. Anyone out there experiencing the same? I tried PRAM reset to no avail. Any suggestions would be great.

Hello David,
If you are having issues using your external display with your MacBook Pro, check the article below to continue your troubleshooting with resetting the SMC as well. Work your way down the article if you still are having issues after that.

Mini Display Port To HDMI Cable Not Working?

Dear members,
i have a mid 2010 13" macbook pro which i have been using a mini display port to HDMI cable which also carries audio for for years now.
I went to use it last night and have to pull the cable out and plug it in a few times to get it to work.
Tonight it just wont work at all no matter how many times i pull the cable out and plug it in again!
Before i use to just connect it and boom, screen would go off then on and it would also mirror on to my TV.
My TV is a 32" Toshiba TV, i tested the HDMI ports, working fine. The mini display port to HDMI cable works fine on my 42" TV downstairs.
Any one know of a fix for this?
Thanks.

Welcome to Apple Support Communities
That's exactly what you need. A Mini DisplayPort to HDMI adapter and a HDMI cable. See > http://support.apple.com/kb/HT4241?viewlocale=en_US
This is the only way to view a video on the TV. After connecting your MacBook Air to the TV, image on your TV should show immediately. Then, press Command and F1 keys to mirror your MacBook Air display, and open the video

Mini display port to HDMI problem...still happening, apple needs to help!

i read a lot about this topic and the question was marked answered, but there was no answer, sooo...
this is just a heads up to apple that this problem still exists and many people are still having it! Please do something... you put this mini display port on your computers... sold them to us... and now dont have software that lets it work... loosing a lil faith in apple today! there were 11 pages on this that i saw, i think it deserves a firmware update!
this next part is a direct copy of a post by sanktcolon and he explained the problem very well, so if your interested...
I figured I would just tell you all about my story. I do not have any solutions, the problem is still ongoing. But first I'd like to clear some confusion.
There seem to be a couple of people in this thread who thinks that when you experience this problem and you plug the HDTV with your MacBook through HDMI, you get a connection with the HDTV and can change the settings. This is not true. What happens is that the MacBook will flash its screen like it does when it detects a TV being connected, but then it will go back to normal. No connection established. Of course, there's people in this thread with different kinds of problems but with similarities. However, the main problem in this thread is quite clear and it's the same one that I have.
So with that out of the way, here's what happens for me and most people in this thread:
I've been using a Mini Display Port to HDMI adapter for quite a while and it has been working great. But lately I've been experiencing issues with it. There is nothing wrong with the adapter nor the cable, and certainly not the TV.
When I connect the adapter to the computer, the screen on the MacBook will flash blue, like it should, but it will not connect to the TV. What does this mean? It means that it detects the TV but is unable to establish a connection with it. Probably because it sends the wrong signals.
Now that's all pretty logical, but here comes the weird stuff. If I continue to try and re-establish a connection, either by plugging in and out the cable or changing HDMI-ports with the TV-remote (the MacBook re-detects when I switch from HDMI1 to HDMI2 and back), it will eventually establish a connection with the TV and work fine. Though, this can take minutes. Plenty of minutes. Last night I tried re-detecting for about 15 minutes and it didn't work. However, this morning it worked quite quickly.
So the problem is quite obviously with the MacBook/the OS and not with the adapter, cable or the TV. It's just ridiculous, and frankly quite annoying, to read posts where people claim you should get a new adapter. Why? Because there's so many people out there with different adapters, and people who have switched adapters and so on and so forth, that experience the exact problem I just describe. So either there's a problem with the MacBook/OS or there's a lot of TVs and adapters out there that are faulty. It's just illogical.
Once again I would like to remind you all that there's no connection, what so ever, between the TV and the MacBook when it doesn't establish one. And by establish I mean that you can actually see the screen on the TV. So bringing up the display settings won't do anything, search for devices on the TV or in the MacBook won't do anything. There just is not a TV there for the MacBook.
I have tried everything posted in this thread and the only thing that works for me is trying over, and over, and over, and over again until it just randomly works.

I too am having this same problem with my Macbook Air (Late 2010 Edition). I think this has something to do with OSX 10.6.6. Before the update, my mini display to HDMI was working flawlessly. Now, when I try to plug in to the TV my macbook just flashes the blue screen with no picture going to the TV what so ever. I'm not sure what was done with the update, but i'd sure like to be able to connect this machine to the TV again! APPLE, HEAR OUR VOICES! Fix this problem!

Why does my mini display port to hdmi adapter cut out intermittently?

I have a MacBook Air 2012. Using a bestbuy mini display port to hdmi adapter connecting to a sony led tv. The picture and sound transmits to the tv, but the signal would cut out after 10-15 seconds and it would last about 3-5 seconds and then the picture would come back again.

to me something happened similar to me but after removing the connector and put it back was solved, and now to use it with my TV I have to make sure both are well connected to both the Mac and plug the HDMI cable and adapter tv .
I hope that solves your problems resolved as mine
Blessings.
a me me a pasado algo similar pero luego de sacar el conector y volverlo a poner se soluciono, y ahora para poder usarlo con mi TV tengo que asegurarme que esten bien conectados ambos tanto el conector al mac como el cable hdmi al tv y al adaptador.
espero que eso resuelva tus problemas como resolvio los mios
Bendiciones.
