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!

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.

Upgrade 09 model with the new mini display port?

Anyway to upgrade my 09 macbook pro with the new mini display port that supports both audio and video instead of just video?

If you are referring to Thunderbolt, no.

Why does iTunes not display hdcp content on my second monitor? The adapter monitor and cable have HDCP Support. This also occurs with a rocketfish mini display port to hdmi adapter.

It works for a time and then fails.
ITunes 11.04.
iMac Purchased Early 2013.

Seems to work when I swapped dapaters from theb 3.0 adapter to the mini display port adapter. THis is the same thing that got it worling the first time byt in reverse.
Had already tried clearing the PRAM. If it occurs again, I will have to try redetecting displays next time. Judging by what I saw reading through these forums it will happen again,

Cant get external Monitor to run under Mountain Lion with Dr. Bott Mini Display port Adapter and Mac book Pro Retina!

Hey there,
somehow I cant get my Zalman Trimon Monitor to run on my new Mac book pro (2012, Retina). I tried hooking it up with the Dr. Bott Mini Display port Adapter see here ( http://www.google.de/products/catalog?client=safari&rls=en&oe=UTF-8&redir_esc=&q =dr.+bott+mini+displayport&um=1&ie=UTF-8&tbm=shop&cid=9085840057573220630&sa=X&e i=rHMeULWUNo7ysgaZvYGYAg&ved=0CHIQ8gIwBg#ps-sellers )
Neither on my new mac book (with thunderbold) nore with the 2010 Mac book pro 13 inch from my girlfriend both running Mountain Lion, would it work. Does anyone has the same troubles or knows a reason or fix? The monitor definitly works (tried with my old mac book) and this is already the second adapter I use, since I thought maybe the adapter doesnt work!
Help appreciated!

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.

How can I connect my Early 2011" Macbook Pro 13" inch, with a generic Mini Display Port to HDMI connector, to a LG 32LD340 LCD TV, using Mountain Lion 10.8.2?

I have an Early 2011" macbook pro 13 inch (core i5 2.3ghz 4gb ram 320hdd) with Mountain Lion 10.8.2, and I want to connect it via Mini DP to HDMI connector, and a HDMI cable to a LCD TV LG 32LD340. When I had Lion OS, I had no problems at all.

If you have an external drive equal to or larger than your internal HD, clone your internal to it with either Carbon Copy Cloner or Super Duper. Test the clone to make sure it's bootable. Then upgrade either one. Try it out first.

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 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:

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.
