HDMI to Mini Display Port problem.

When I connect my MacBook Pro 13" (early 2011) to my TV using my HDMI to Mini Display Port adapter the MacBook just shuts off completely. I can use a VGA adapter no problem but I would like to get better picture quality from HDMI. Anybody have any ideas what the problem is?
Thanks in advance.

Have you tried a different adapter/cable? This is where I would start. (see if you can borrow some).
You can also try these resets:
NVRAM/PRAM:

These are start points, gotta start somewhere, right?

Can i use a hdmi to mini display port cable to use my iMac as external monitor for a windows laptop?

Does anyone know if a hdmi to mini display port cable can be used to link a windows laptop with an 27 inch iMac to use the iMac as an external monitor. Or are there other options to connect my DELL latitude 6430?

Is the 3.5mm-to-optical cable any better than using a standard 3.5mm? I don't know too much about this stuff. My thought process was that if the source of the connection is a 3.5mm jack, does it make a difference using a cable that starts as a 3.5 and converts to optical?
Chances are excellent that if your receiver is less than 20 years old it has an optical input, this is a digital signal which will sound MUCH MUCH better than using an analog 3.5MM to 3.5MM connection. I recommend using the cable suggested or one with the same connections but of a different length if your needs warrant it.

HDMI to Mini Display Port not working?!?!

Hi,
I use my macbook Air (latest one with mini display port) to watch movies on my TV. I use a hdmi to mini display port adapter cable which worked perfect for about 6 months. Yesterday, I plugged my mac in and nothing appeared. I have no idea why- no settings have been changed.
As usual, the screen goes blue and then back to normal but the TV screen is plain black. In the Display settings, the 'arrangements' tab is missing where I can set mirro displays things. I tried bying a new adapter and trying this with my sister's macbook pro but it still doesnt work.
Any ideas on why this has happened & to how I can fix it?
Thanks for your help

This is probably NOT the solution you're looking for, but use a 3.5mm to 3.5mm (headphone jack) cable to transmit sound. I use stereo speakers with my setup, sounds far better than the TV.

Problem with HDMI to mini display port

I have been using the HDMI adapter to mini-display port successfully with my TV for months. I have a late 2011 Macbook Pro. My brother borrowed the cable to use with my mom's 2013 Macbook Pro retina display and now the adapter won't work. He could not get it to work with her Macbook and had not realised that it had HDMI input so used that instead. Now he returned the adpater to me and it does not work! I am running software version OS X 10.9.2. I read about a lot of problems similar but they seem to relate to 10.8.2 software. Can anyone help or advise me why my adapter has given

I have two adapters and both have stopped working after using them with the later (2013) Mac. I think it may have damaged them in some way!

Thinkpad Twist s230U no internal display, works on HDMI and mini display port

Hi,
My Thinkpad Twist does not display anything when turned on except on external monitors. The Device manager shows a greyed out internal display icon, says it is not connected.
1. Could this be the power connect ribbon cable p/n DC002C003W00 have a fractured wire(s)? I have tested for open circuit between PWR1 and PWR2 connectors and there are 4 sequential pins which are open circuit. Is this normal?
2. The touch screen works
3. There appears to be absolutely no LED backlighting working
4. Is there a possible fix for this and if so is it the power cables or some physical problem with the ribbon cables OR is it definitely a new display that is needed using existing cables?
Thanks in advance
Andrew

The last 4 pins on the connector are unused I have determined so it is not the power ribbon cable connector.
I found two wires fractured in the LCD ribbon cable right at the point where it feeds through the twist mount. I expect this could be a common problem after use. After repairing these two wires it did not fix the screen problem. I have ordered a replacement LDVS ribbon cable and will report back once I have replaced that.

HDMI, Mini Display Port and Mountain Lion

Hello,
After reading about numerous issues concerning the Mini Display Port and Mountain Lion, I'm trying to discuss it here with you all to see if there is any solution.
I have a MacBook Pro (2009), and used it with my TV (HDMI cable + Mini display port adaptor) with Plex media center back when it was on OS X Lion. It was very convenient because as a portable computer, it could easily be set near the TV and allow the use of a remote to sit in the couch and stream media from the Time Capsule… without the help of any expansive box. Perfect setup I've had for over a year.
The thing is, since I've upgraded to Mountain Lion, when I try to connect the MacBook Pro to the TV, the screen turns blue as if it was calculating the resolution of the monitor so… ok. Until it comes back, and nothing changed either on the MacBook Pro screen or on the TV.
Harware side, I've tried with the computer open, closed, I've checked every port and connection on both computer, TV and adaptor.
Software side, what I find really annoying in Mountain Lion is that they completely ditched every monitor setting as long as nothing is connected — and even if the Mini DP is connected… the Mac thinks it's not. I even tried to reset the PRAM. This is a nightmare.
I've tried to do the same with my iMac (mid 2011), and it all worked properly. What I can't explain is why it works on my iMac and not on the MBP… as they have the same configuration !
I don't know if Apple is outcasting old devices so people buy new Apple stuff or if they ditched the HDMI out on certain (old) devices on purpose so users replace it by the new airplay mirroring feature and buy the Apple TV. I won't, because let's say it's a total crap compared to other media center solutions. And I'm bored of Apple.
Please, HELP NEEDED ! Has anyone had the same issue ? I bet you have ! Now how can we solve that ?
Thank you for your time.

EDIT : stopped working on iMac too… then update 10.8.2 fixed the issue. Now it works. Thanks Apple for temporarily removing some features ! It's just so ANNOYING.
Hope you gonna stay with the few we have left on Mac and stop removing things randomly. Not event talking about the pro environment (designers, developpers, etc.) that is almost gone. 2 years and our macs will be tablets. Careful with the old clients… it's been almost 10 years I'm on a Mac and I've never been so unhappy.

Female Mini Display Port Adapter - Connect Monitor to Non Mini Display Port

Anyone know of a Female Mini Display Port Adapter, so I can connect the 24 LED Cinema Display to a computer that has DVI connector? Or hook the monitor up to a KVM, so I can use the monitor with multiple computers?
I know Apple doesn't make these, but does a third party?
Monoline appears to be coming out with adapters to hook a mini display port computer to DVI and HDMI, but not a mini display port monitor to DVI or HDMI.

'Mini Display port' is just a smaller version of display port, which is a slightly different version of HMDI.
No. You may be thinking of Mini DVI. Mini DisplayPort is a smaller verion of DisplayPort, which is different from DVI and HDMI.
<http://www.displayport.org/white-papers/whitepapers/DPTech_OverviewEnglish.pdf>
HDMI, display port, mini display port AND DVI are all capable of being 'converted' from one to another.
It is easy to make a Mini DisplayPort (card) to DVI (display) adapter because a DisplayPort card can be set to generate DVI signals. (Dual-link DVI is a bit more complicated since the adapter must sepatate the clock and data.). A DVI card cannot generate DisplayPort signals, so an adapter for a DisplayPort display with a DVI card would be a lot more complicated.
The ONLY thing that you would LOSE in a DVI to display port conversion is an audio signal.
HDMI is DVI video plus digital audio. DisplayPort does not use DVI video.
The point is they are all interchangeable, signal wise.
No. A DisplayPort card can generate DVI signals when a DuisplayPort to DVI adapter is detected, but a DVI cards cannot generate DiusolayPort signals.
But why should Apple make a cheap DVI to female display port when they can make more money on overpriced graphics card upgrades?
They can't make a cheap adapter, but they could have added a DVI port to the display.

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!

Mini Display Port to HDMI sound problem

I have an iMac 11, 2 (MacOS X, 10.6.8). The Mini Display Port is supposed to be able to carry sound, (using a Monoprice Mini DisplayPort to HDMI Converter with Audio, and HDMI cord supporting 3D, and Audio Return.) I am playing downloaded movies with VLC, which works fine on the computer. When I try to burn DVD disc using Toast Titanium, I get video, but no sound. So, I figure I can watch movies on my Vizio 42" TV screen with the MiniDisplayPort to HDMI cord. I learned that to use the MiniDisplayPort I have to go to click the box for Mirror Display. In System Preferences--- Sound---- Output Tab, the only two choices are: Headphones...... Headphone Port, and E3D420VX....... HDMI, neither of which seem to help "push" sound through the MiniDisplayPort.
So, I give up and watch the movie on the Vizio screen (through the HDMI cord), while listening to sound on the little computer speakers. After watching a couple of movies, and then not doing anything for a few minutes, all of a sudden the movie starts replaying off the play list, and lo and behold..... sound coming through the TV speaker system!!! (So, I know the HDMI cable is capable of carrying audio.)
If any one can help me figure out how to get sound through the HDMI cord all the time, it would be greatly appreciated!

Hello,
Long shot, but...
Open Audio Midi Setup in Applications>Utilities, see the input & output options & KHz setting there, some things will change it for their own use, then not set it back.

Mini display port to HDMI - negative picture issue

I bought a new Macbook Pro 13,3 inch laptop last week and added a 120 GB ssd and 8 GB of RAM. I'm loving it!
Something I'm not loving however is the issue with the Mini Display Port / Thunderbolt when connecting with a MDP-HDMI adaptor. I watch a lot of movies and so hooking the computer up to my Sony BRAVIA 46 inch TV is quite important. Everytime I do the picture and sound are great! For about 5 minutes... then the picture goes "negative" you know that turqoise look?? Like a negative image. The sound is still there, the picture is just affected. To remedy I have to turn the tv off and restart the movie. Very annoying doing this ever 4-5 minutes!!
Is there a fix of some sort? Apple should really release an update for this.
Thanks!

sounds more like a hardware failure.
Try a different monitor to see if the problem persists, in which case that would point to a bad video card... or try a different source with your monitor(another computer), and if the problem persists, that would indicate a problem with the monitor

Mini display Port To HDMI not fully working with tv

Ok So, I am using and 13" macbook Pro Alu (march 2009) and a 40" Samsung LED 120hz 1080p screen (Brand spankin New!). I am connecting the two between a dynex mini Display port adapter to HDMI out. Then have an HDMI cable Running from the adapter to the TV.
My Problem:
When i connect the two together The output to the TV doesn't Fit the whole Screen. There is about a 4 inch Gap on the sides that are just black and about an 1 1/2 inch gap on the top and bottom. This was how it was on my old tv and was hoping it would just work better on the new tv. The old tv was 720p 32 inch toshiba. but it is very frustrating because i use ableton and it defeats the purpose of having such a large display if it doesnt work properly. ive read a couple forums that were similar but non were the exact problem nor the right solution. I downloaded switchresX and it gives me higher resolutions to output but it does not change the gap. Im starting to think it may be a setting on the tv but i have yet to find anything that with fix it on either the settings on the TV nor the computer. please help thank you

When you're in Extended desktop mode (not mirror), and you Open System Preferences > Display, there should be a preference on your main screen and one on the TV. The one on the TV should have the underscan setting like this:

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

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.

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.

Mini display port to HDMI adapter not working

I can not get my MacBook OS X to dispaly on my new Samsung LED TV. I have a mini display port to HDMI adapter (two years old) conneted with an HDMI cable (new) into the HDMI input on the TV. I tried both inputs, tried resetting the TV, plugging, unplugging, restarting, checked all my system preferences...I can not figure it out. I took my cables to a local store, tested the HDMI cable, and it works. Tested the adapter and they had the same problem I have on my Mac. The screen will flash blue when you plug it in, but will not show up in the TV. I think the adapter must be bad, nothing else makes sense???

Hi Kater24,
Apple doesn't make a Mini DisplayPort to HDMI adapter, so the one you've got there is a 3rd party one that's designed to work with the Mini DisplayPort on your Apple computer. The adapter is pretty much plug-n-play, there's no configuration necessary. Plug it into the machine, the HDMI cable from the other end of the adapter into your TV, select the HDMI input on your TV and fire up the computer.
If that's not working it's possibly an issue with the adapter and/or cable to the TV. Any chance you might have access to another TV for troubleshooting purposes?
