I purchased a 3rd party mini displayport to hdmi adaptor. My 2011 macbook air with thunderbolt wont detect the display.

Is the display turned on? Sometimes it is the simplest of solutions, when details are missing.

I have just tried to connect my Mac book pro to an LG Plasma TV via an iWires Mini DisplayPort to HDMI cable. All I get on my TV is the Mac wallpaper and nothing else. I am missing something really silly, could anyone help please.

I have just tried to connect my Mac book pro to an LG Plasma TV via an iWires Mini DisplayPort to HDMI cable. All I get on my TV is the Mac wallpaper and nothing else. I am missing something really silly, could anyone help please.

Hi there. I also bought an iWires mini Display port to HDMI cable and have an LG LED/LCD TV. I plugged it in to my MB Pro and followed the very small writing that came in the package and got both audio and video going. You need to change the audio settings from within System Preferences on your Mac to select your TV as the audio output.
My concern is the data latency - do you experience a delay between moving your mouse on the MBPro and the TV displaying the movement? It is only a fraction of a second, but certainly enough to be annoying, especially in a cable as expensive as the iWire.

Can i connect a "Mini DisplayPort to HDMI Adapter" to my macbook pro and t.v without having to buy the hdmi adapter?

I have a macbook pro 13 inch running on mavericks 10.9.2 and i was wondering if i could just use the "Mini Display Port to HDMI Adapter" and connect it directly from my computer to my t.v? because i see a lot of people on youtube connecting the "hdmi adapter" to the computer first, then connecting a regular HDMI cord to the adapter, then lastly to the t.v........ Does it make a difference whether or not I connect a "HDMI Display Port" directly from the computer to the t.v without using a adapter to connect with a regular hdmi cord??? what is the adapter really for anyways???

eric199398,
without knowing precisely which computers the people on YouTube are using, it’s hard to say whether they’re taking unnecessary steps or not. You should be able to connect the Mini DisplayPort side of a Mini DisplayPort to HDMI adapter to your Thunderbolt port, and connect the HDMI side of the adapter to your TV’s HDMI port.

Macbook Pro with Retina wont detect monitor on mini display port to dual-link dvi adapter

So after reading Jeff Atwood's post, I decided to jump and give it a shot. So this week I got my monitor in from Korea, and I already had my Apple mini display port to dual-link dvi adapter, hooked everything up - and nothing. Monitor doesnt show a signal, and no display shows up in user preferences.
To verify the monitor actually works, i plugged it into my windows box - and boom, right away there it is in all its glory. So I called apple support, after spending about an hour going through the "are you sure its plugged in stuff", the tech finally admitted to being stumped and blamed the adapter. Not to be deterred, I then went to my local apple store and talked them into trying their adapter to rule out the adapter - regardless of the adapter, the mbp wont detect the monitor.
Just for fun, i tried my old single mini displayport to single dvi, the monitor is recognized, but that obviously cant drive the right resolution, so i just get a backlight. Same deal when i try the hdmi port with a hdmi to dual-link dvi adapter on the end of it. Also tried display port to the same hdmi with adapter on it (the joys of working in a dev shop - cables to test everywhere)
I have read / tried a ton of things:
re-installed / uninstalled air display, just to be sure it was gone. went through all my apps just to see if there is anything like this i could think would be effecting it
install gfxCardStatus to ensure i am on the nvidia (discrete) and not the internal card
Played with different settings on SwitchResX to try to force the res over hdmi - no love - os rejected each one
I bought the monoprice adapter wondering if it was just the apple adapter since the apple adapter has been panned, no love from it either
Reset the PRAM countless times
I have two other adapters coming in to test with in a day or two - maybe one of those will be magic, but at this point i kinda think its software on the mac. My Spec:
I am running Mountain Lion with all the latest updates
New MBP with Retina (2.6g processor, 16gig ram, nvidia video card)
Here is the ebay link to the monitor
Now the other weird thing is pretty much universally these auctions say the monitors cant be run on a laptop - which makes no sense to me, because its just a connection, if the video card is strong enough (which my machine better be) it shouldnt matter the source. The listing mentions its a "by-pass" monitor, which is something I and google have never heard of.
So any sage words to make my day?

Magic was, I have to have the adpter plugged into the mac, let it recognize all with the monitor powered off.
then power on the monitor, and boom gloriousness
For future generations, setup that works:
1) MacBook Pro with Retina
2) Monitor From Korea (example auction)
3) Accell Mini DisplayPort to Dual-Link DVI Active adapter (amazon)
4) Boot mac, plug in adapter, let it recognize the monitor, power on monitor

Mini-DP to HDMI doesn't work MacBook Air 2013

Hey all!
I've bought a iWantIt Mini-DP to HDMI/DVI/DP adapter. (This one specifically: http://www.pcworld.co.uk/gbuk/pc-accessories/apple-accessories/apple-accessories /iwantit-imdhdd13-mini-displayport-adapter-21359616-pdt.html).
On my 2013 MBA running OSX 10.9.1, I try to connect to my Samsung TV via HDMI. The screen flashes when the HDMI cable gets plugged in, but then nothing happens after that. The TV doesn't seem to be recognised at all, and when I switch to the HDMI port the TV says there is no signal. I've tried all the, restart with the HDMI cable plugged in, plugged out etc but nothing like that has worked.
Does anyone else have any issues like this?

Then unless there's some newer/different setup in 2011 13" MBP (if so, I'd look in Displays), it sounds like a hardware issue, either with the cable or the MBP.
I would contact AppleCare, as you are still in your three month free phone support, and one year hardware warranty.

Mini DisplayPort to HDMI Adapter... no audio

i just purchased a Mini DisplayPort to HDMI Adapter for my MacBook Pro 2012 and have connected to my TV. I have video, but no audio. Does anyone know how to get the audio to work?

I might be wrong but the MBP 2008 does not have audio supplied capability over MDP to HDMI.

It would help to know which one of the 9 different models of MacBook you have. To see which model you have go to the Apple in the upper left corner and select About This Mac, then click on More Info. When System Profiler comes up check the Model Identifier and post it back here.

Mini Displayport to HDMI Adapter - Sound?

I have hooked up my mini by the Mini Displayport to HDMI adapter to my Philips FlatTV. Sound is only played by the internal mini speaker, not from TV.
According Apple Support the sound should be working on the TV when using the adapter. They reckon my adapter is broken.
I know that there is no sound from the Minidvi to HDMI adapter unless you use external audio cable, but with the Mini Displayport?
Has anyone actually managed to make this work?
Thanks!

As already pointed out in this thread, Apple currently do not support routing audio out via the Mini Displayport connector even though the Displayport specifications allow for this. Therefore a 'standard' Mini Displayport to HDMI adapter will not be able to provide audio since the Mac will not be sending it.
However many people have been disappointed with Apple's omission and as a result at least one manufacturer of adapters has developed a solution to workaround this.
If you look at http://www.monoprice.com/products/product.asp?cid=104&cp_id=10428&cs_id=1042802&pid=5311&seq=1&format=2 you will see the 'standard' style Mini Displayport to HDMI adapter which due to Apple, does not currently provide audio. If you however look at this model http://www.monoprice.com/products/product.asp?cid=104&cp_id=10428&cs_id=1042802&pid=6331&seq=1&format=2 then it gets round the problem by connecting to both the Mini Displayport on a Mac and the Mac's Mini TOS-Link digital output and then 'merges' them together before sending them out via a single HDMI cable. This would therefore provide audio to your TV.

Mini DisplayPort to HDMI Adapter by Belkin for iMac 2009 failed to work

This is an SOS message. I have purchased another Mini DisplayPort to HDMI Adapter and I have iMac (27-inc, Late 2009) running OS X Yosemite (Version 10.10.1). I have carried out the connection of Mini DisplayPort to HDMI adapter to LG Plasma TV Screen, but there is no sign of any of the equipment reading or aware of the connection. Is there anybody out there who can help me make it work? Also, why is that Yosemite - System Preference, click on Displays does not contain - Arrangement? I'll greatly appreciate any useful tips from the community or apple support team.

Eric has helped in providing in dept understanding around the subject matter, but unfortunately, it has not provided the solution to the problem.
The Mini DisplayPort to HDMI Adapter when connected to the external Plasma TV screen, nothing happens. The System Preferences was accessed -and the Displays monitor sign was clicked, but it only showed - Display/Colour, which according to the instructions / descriptions contain in the - Video Troubleshooting Internal and External Monitors literatures and video, there seems to be missing - Arrangement / or AirPlay from my OS X Yosemite version.
The above is the version of OS X Yosemite - showing on my *iMac when clicked on System Preferences, and as result I have not been able to make the Mini DisplayPort to HDMI Adapter to LG Plasma TV Screen to work.
My *iMac is -
iMac (27-inch, Late 2009)
iMac10,1
(10.10.1)
MB952XX/A
Running OS X Yosemite
When the above image is compared with the following image below, there is definitely something missing and it’s probably affecting the Mini DisplayPort to HDMI Adapter to work in my connection.
Questions:
How can I make my iMac 10,1 (27-in, late 2009, currently running OS X Yosemite 10.10.1) to have the above AirPlay mirroring or Arrangement to activate the connection?
Are there other ways I can make the connection to work?
Is there any body who has a similar iMac specs and OS X Yosemite who has overcome connecting to external Plasma TV Screen?

Mac is not connecting to TV after using Mini DisplayPort to HDMI Adapter Cable?

Macbook Pro is not connecting to TV after using Mini DisplayPort to HDMI Adapter Cable. 2010 Macbook Pro, just purchased Mini DisplayPort to HDMI Adapter Cable from Amazon. Link here: http://www.amazon.com/Mini_Dis-HDMI-CB6-Mini-DisplayPort-Adapter-Cable/dp/B003OC 6LWM/ref=sr_1_2?ie=UTF8&qid=1406238976&sr=8-2&keywords=mac+to+tv --When i connect both ends of the cable to the TV and to the laptop, the screen will blink, but then afterwards it will not mirror on the TV. I have tried going to display setting but cannot find the arrangements tab. When i searched "arrangements" a message said, "The Arrangement tab of Displays preferences is hidden because you only have a single display attached to this computer." Not sure how to fix this problem. I have connected this laptop to a TV before, but with a different cable other than the one i just purchased. Any help would be greatly appreciated, thanks.

Found the fix. Still don't know if it was Windows, iTunes, or Norton 360, but this worked immediately for me:

I found a solution posted from Rodfromnework for PC users. It worked for me and easy to do.
Start --> Programs --> Accessories (Right Click on Command Prompt) --> Run as Administrator
then type in:
Netsh winsock reset
Hit enter, restart PC, open iTunes, go to Store
Hope it works for you too.

Is HDCP protection always on when using Mini DisplayPort to HDMI adapter?

I'm trying to capture my MacBook Air (2010) desktop for use in a Podcast.
So I purchased a Mini DisplayPort to HDMI adapter and plugged that into a HDMI capture card on another machine.
Unfortunately it keeps telling me the stream is protected and it won't display anything.
I've tried my 2010 iMac and 2011 Mac Mini too, but they all produce the same issue.
If i plug them directly into a TV instead then they display fine, but not when connected to the capture card.
A windows based laptop with HDMI out works fine as does a DVD player. But when I attempt to play a cop protected DVD - then the HDCP kicks in and the picture is blocked.
Does anyone know if there is a way to display just the Lion Desktop without invoking HDCP protection?
Thanks in Advance
Anthony

Is the failure repeatable? If not, I would forget that it happened once and move on. It had something to do with pages moving in and out of the registers. S**t happens.

Mini Displayport to HDMI Adapter Problems!!!

Okay so I have a MacBook Pro running OS X version 10.5.8.
2.4 GHz intel core 2 duo
And I recently got a Phillips flat screen tv with HDMI hook ups.
So naturally I wanted to connect my Mac.
So I went to Best Buy and purchased the Rocketfish mini displayport to HDMI adapter.
However upon connecting everything to my computer, nothing happened.
No picture came up on my tv, no sound, no change at all.
My computer doesn't even say there's a device connected.
Is there some sort of steps to setting it up?
I was under the impression I'd just have to plug it in and it would work.
Do I need to get another adapter?
Please help!
Thank you!

Took the MBP to the apple store. The display port works fine.
Embarassingly the tech pointed out the USB plug on the adaptor which I hadn't connected thinking it would be for another peripheral. Hey presto it worked!
Red faced thanks!

MacBook Pro 13" mid 2010 model (7.1): Mini Displayport to HDMI , no Sound

I bought my MacBook Pro on October 2010.
Also, in the SystemProfiler I can see that the "Audio Built-in" has HDMI in the list. And my macBook Version is 7.1 and am having OSX 10.6.7
I recently bought Sony Bravia KDL-40EX720 LED HDTV. And tried connecting the Display using a Mini-DisplayPort to HDMI. The Video works fine but cant get audio working. Also, the SystemPreference->Sound->Output has only Internal Audio in there.
Today I even tried with my office LCD HDTV from Samsung and Toshiba. Got the same result .. no Sound.
Where as my Father's MacBook Pro 13" which he got a couple of months earlier than mine got both Video/Audio working on his Panasonic Plasma TV. He is also using the same MiniDisplayPort to HDMI adapter I am using. But as I live some thousands miles away from home i can't check by connecting the Panasonic with my MacBookPro.
I have been looking out the forums and post all over the internet for any solution or relief but none so far. I still haven't had a clue if its the TV or the MacBook thats having this audio via HDMI issue.
Any, suggestion will be highly appreciated.
Regards,
Sapam

I have the same MBP Version 7.1 that you have and it also states in the System Profiler HDMI Display port
Output: Connection : Display. Now what that means, im not sure.
But i have also connected an HDMI cable via an adapter made by iWires Tech Link purchased at the Apple store and have the same problem as you, only video with no sound from the TV.
I've looked at the settings that eww has suggested in System Preferences > Sound > Output tab and their is no options available for HDMI out, or Display Audio or anything else for that matter, except built in speakers, and Audio port for sound output.
Which lead me to use the Audio port to send the sound out via an amp and speaker system independent to the TV.
Thats why i researched for the other adapters which send out the sound and the audio through the same adapter.

No audio via Mini DisplayPort to HDMI Adapter

I have a late 2008 model (MB470LL/A) 15" MacBook Pro running 10.6.7.
I purchased a Dynex Mini DisplayPort to HDMI Adapter that's not picking up the audio signal. The video plays fine via HDMI to our TV, but no audio.
In looking online I've seen this is a known issue. Has anyone discovered a work around other then running a separate audio cable from my computer to the TV?
I'm really surprised there is no audio this way. Someone dropped the ball on this one.

I might be wrong but the MBP 2008 does not have audio supplied capability over MDP to HDMI.
