Using Mini DisplayPort to HDMI cable

Using a Mini DisplayPort to HDMI Cable from a 2010 MacBook Air is playing up, making it practically unusable. Essentially what happens is that when connecting a television set using a Mini DisplayPort to HDMI Cable the picture is perfect but no longer than 30 seconds at a time before the picture 'goes to sleep'. Is there a setting I need to change? There must be a setting that I can change which I haven't worked out yet. Thanks in advance for your help

has there been an answer to this yet?

2009 24-inch iMac 3.06GHz (EMC no. 2267). I don't get any audio when connecting my Sony HD TV to my iMac via mini DisplayPort. Is there a fix or hardware upgrade? I'm using a Kanex Mini DisplayPort to HDMI cable w/ audio support.

You can connect the audio from your iMac to your TV using a mini jack (like headphones plug) to rca (regular red and white audio connectors used on every TV,DVD, etc) cable.
On your TV, you need to be able to set the audio for the HDMI input you will use to "analog" and connect the rca end of the cable to the analog inputs on your TV.

Dave I'm glad to say that it works perfectly but I'm embarrassed to say that my 12 year old nephew hooked it up in about 10 minutes.
If you have the Kanex Mini DisplayPort cable it will work, what confused me was changing the display settings in System Preferences,
and dragging the mac screen from the mac onto the tv. Sorry I cant be more helpful but you have the right cable now you need a 12 year old nephew.
Good luck Derek

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.

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.

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.

27" cinema display and female mini displayport to HDMI cable.

Hi,
I need to connect my 27" cinema display to an AV amplifier. In order to do this I need to find a mini displayport cable with a female connector on one end (to plug in to the monitor cable) and a male HDMI connector on the other.
Does anyone know if such a cable exists? and if so where I will find it?
Ideally I would like to do this with just one cable...using adaptors, eg mini displayport to displayport then displayport to hdmi are an option, but not my first choice.
Many Thanks,
Mark

Kanex XD - HDMI to Apple iMac 27-inch and Cinema Display 27-inch

Dr. Bott Mini DisplayPort to HDMI cable doesn't work.

I'm trying to connect my MacBook (mid 2010) with my tv and I can't get it working properly. I have the HDMI cable, and the mini display port to the HDMI cable. When I connect the computer to the tv, the computer screen turns light blue like it is about to synchronize, but the tv screen remains black. After a moment, 2 boxes appear on my tv screen. One says "HDMI1: and the other "no signal detected".
I've tried with "detect displays", I've tried connecting to all the HDMI ports I have on my TV, I've tried basically everything but it still doesn't work.
This is the adapter - http://www.drbott.net/product/7395-MDPA/
My TV is a fairly new Samsung, and everything else is working fine, I don't know why this won't function. It's frustrating me.
Any help on this matter would be greatly appreciated. Thanks.

When I have this problem, it is because my Macbook Pro is using "Integrated" graphics vs the "Descrete" graphics. I control this via the gfxCardStatus menubar utility.
You could also try reseting the smc controller

and/or resetting the PRAM

HT3913 Can I connect a Sony TV 32 inch to my late 2009 iMac as an external display using Mini DisplayPort to HDMI?

Seems doable--can I?

Hello, All-
I too am very interested in the answer to this query. Same set up, same fail w/the Thunderbolt cable. The Genius Bar at the Apple Store was no help & recommended I bring my 27" iMac into the store...seriously? Their ultimate answer was that I needed a plain old male-male mini display port cable....that the Thunderbolt cable was the problem. Bloody unlikely, I say. Another guy in the store agreed with me this morning, so swapped out the cable. I was hoping upon hope it was a bad cable, but no such luck—still nothing. Next I tried a mini-display-port-to-DVI adapter—DVI cable—mini-display-port-to-DVI adapter. This also did not work. Is there a chance that the iMac running Snow Leopard and the MacBook running Mountain Lion is the problem???

Connecting HDTV with mini displayport with HDMI cable dos'nt work

MacBook pro 15" mid 2010 when connected is nothing to see on HDTV. Could you give me some advice? thank you

Did you look at System Preferences>Displays? Does the category 'Arrangement' appear? Did you click on 'Detect Displays'?
Have you examined the instructions that came with your TV? There should be settings for an external PC/computer.
Ciao.

Mini displayport to HDMI adapter? or cable?

which would be a better connection for macbook pro to HDTV, a mini displayport to HDMI adapter with cable? or a mini displayport to HDMI cable??

I would opt for a single cable such as this eliminating the adapter. The less connections, the better:

Mini displayport to HDMI = fine. Mini displayport to VGA = terrible on late 2011 MacBook Pro. Any ideas?

Hello,
I have a late 2011 unibody MacBook Pro. It has a real problem displaying through a projector or tv using mini displayport to VGA. I connect it to my tv at home with a mini displayport to HDMI cable and it works fine. If I have to connect through a VGA adapter/cable to a tv or projector for work the image always looks like the contrast has been turned right up and it looks awful. I have tried creating a profile, calibrating the secondary display and adjusting gamma settings but it doesn't make any difference.
If I plug my old black MacBook into the same projector/tv using VGA it works fine so I now have to take 2 laptops to work which is ridiculous. I thought it might be the adapter itself but at a recent event a colleage experienced exactly the same problem with his identical set up so I thought it might be something to do with the projectors set up at the event but I recently tried connecting to a projector at a different event and got the same results and now I'm confused. I guess it must have something to do with the adapter but not sure what.
Any help much appreciated.

You really have to mess with the resoluton, espescially the refresh rate, as it varies from projector to projector, monitor to monitor. Even within the same brand! Because so many manufacturers are trying so many different things to become the next cool kid on the block, and the way the formats are being configured that's now part of the game.
That's why so many professionally produced corporate shows hire a dedicated projectionist for the video presentations. Too many bugs in the honey.
Refresh & sesolution are the first things to look at.
Just so you know that colors in PowerPoint PC, and PowerPoint Mac, don't exactly match... go figure.
I forgot to mention another thing, sometimes it's the projector that needs to be tweaked.

Mini DisplayPort to HDMI ----

Hello Apple.... Are you there Apple?
I have this shiny new MacBook, but I can't elegantly plug it into my HDMI TV.
Make the cable. Get it on the shelf.
Tardiness and neglect make for agro customers..... Grrrrrr....

Right just posted the following message to Apple via the above link:
Hi, I recently "converted" from a Dell laptop running Windows Vista to a shiny new Aluminium 13" MacBook. In general I have been very pleased with the experience and really love OSX and the MacBook. The one disappointment is that I cannot now attach my laptop to my Sony TV via HDMI which I was able to do with the Dell and Windows. I cannot find any Mini-DisplayPort to HDMI cables. There are some suggestion on the internet that I could use a Mini-DP to DVI cable and then another DVI to HDMI cable to plug into the TV, but this seem a poor option as DVI does not carry sound. The thing I really don’t understand is why the latest and greatest laptops available don’t have an easy option to connect them to the de-facto standard input on all new HD TV’s, which is HDMI?

Macbook Pro Mini Displayport to HDMI problem Please Help!

I just bought a new Macbook Pro Core i7 15" and have it connected to a [URL="http://www.amazon.com/Samsung-P2370HD-23-Inch-1080p-Monitor/dp/B002DHS398 "]Samsung P2370HD[/URL] via a [URL="http://www.kanexlive.com/products/item-id-3689.html"]Kanex Mini Displayport to HDMI cable[/URL]. I'm running Snow Leopard 10.6.3 and have the resolution @ 1080p via system preferences and the "underscan" feathered a bit... (which I do not understand why I have to do this since I'm outputting at 1080p and the monitor accepts full 1080p as well. Can someone explain this?) however, small text is grainy, some larger bold text has a white wash behind it. Most things seem to have a slight blur as if there is a screen zoom happening just slightly. [URL="http://www.mac-forums.com/forums/apple-desktops/181687-mac-pro-samsung-ln 40b530-display.html"]As described in this similar post I found.[/URL]
My old setup was a late 2007 Macbook Pro 15" 10.6.3 connected to the same monitor I have now via Dual-Link DVI and it was crystal clear... It's hard to believe that the issue lies with Samsung, I've tried the same setup on my Sony Bravia in the living room, being that it's a much larger tv...I can't notice the artifacts as much but they are still present. Something is off.
My only other option I feel is to try a Mini Displayport to Dual-Link DVI but I chose the HDMI route for it's standardization and when I go to meetings/projections it's convenient to have one cable. Yes, I've checked cables, restarted everything ect... Can anyone help me troubleshoot this?
Thanks in advance!

Switched to a Mini Displayport to DVI cable and it works flawlessly. Still no idea, why the hdmi cable does not work properly.

Mini displayport to HDMI (audio compatible)

Bought mini displayport to HDMI cable to connect new imac (21.5" i3) to tv (SONY bravia). It says it is audio compatable but its not sending audio, video works fine though. Any ideas?
Thanks

all hdmi cables will support audio what you need to fins out is if your mbp will output audio from the mdp there are a few ways to find this out easiest is if you bought the computer after april 2010 then it does you just need to get the right adapter this one works with both both video and audio http://store.apple.com/ca/product/H1824ZM/A?fnode=MTY1NDA3Ng&mco=MTgwOTAzMjI have fun
