  • 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

  • MBP 15' 2011 Mini display port to LED monitor/TV resolution issue

    Hello,
    I have just bought  a Mini Display - VGA adaptor which I am plugging to a Samsung 23' LED monitor via a VGA/DVI adaptor. I manage to get a clone view but unfortunately, the maximum resolution offered is 1650x1050 when my Samsung LED monitor has resolution of 1920x1080. Therefore, part of the screen remains black.
    ... also, when I plug the Mini display port to VGA to my Philips 47' VGA port, I got a message that there must be a problem with the connection and again, maximum resolution offered if 1440x10..  and therefore 20% of my TV screen space remains black.
    At last, when I launch Windows7 via bootcamp, this is even wost : when I select the max resolution (1440x10..), the pictures remains freezed on my TV and I can't even move the mouse (while the mouse is moving on the MBP screen...). Only coming back to a very small resolution 800x600 or so will enable me to get control of the win7 desktop on my TV...
    Thank you in advance for your help

    If you are using the monitor in Mirrored mode, its resolution setting will always be exactly the same as that of the built-in display. I presume you have the high-res 15" MBP display, with a native resolution of 1680 x 1050. If that's true, I suspect your monitor is indeed in Mirrored mode, and that's why you can't set the monitor to its native 1920 x 1080 resolution. If you press Command+F1 to toggle the mnitor into Extended Desktop mode, you'll be able to set its resolution independently of the built-in display. Or if you use only the external monitor, with the MBP display closed, you'll be able to set the monitor's resolution to whatever it supports.

    Stacking one video adapter on top of another is usually a recipe for trouble. It's always best to keep things as simple as possible. Use one adapter that gets you from mini-Displayport to whatever input you want to use on the TV or monitor.

  • Mini Display Port to VGA Adapter Resolution Issue

    Hi there folks, I just had to replace my NVIDIA 8800 so I opted for the upgrade to the ATI Radeon HD 5770 (Apple part number: MC742ZM/A)
    I have two monitors on my desk, an apple 30" cinima display and a smaller 19" Hyundai monitor that uses a VGA connection as my second display.
    After hooking up my Cinima Display to the DVI, and the Hyundai to the Mini Display Port via adapter and restarting my Mac the second monitor does not show up. Well, It appears on the arangement screen, and on the system profile screen, but no image appears.
    If I unpluged and replugged the monitor  then I can get an image to appear. Only I cannot change the resolution from 800x600. The monitor supports 1900x1200.  I can see the correct resolution in the list, however selecting that resolution will not stay. It always reverts back to 800x600. I tried several other lower resolutions and none of those work either.
    I zaped the PRAM, checked for system updates, hopped on one leg and cursed the gods but nothing has worked so far. I can give tech support a call tomorrow, but I was hoping someone on the forum knows of a solution since I know many of you are smarter than the tech support folks.
    Thanks in advance!

    I had the exact same problem. It actually escalated from there and it would crash at the startup screen (the white one with the apple and the spinning gear). The only way I was able to fix this was to reformat the entire computer. I was lucky enough to have backed up all my data when it first started crashing. I've only reformatted yesterday and things seem fine for now. I don't know what caused it, or how to fix the problem any other way.

  • Mini display port to HDMI...help

    I have all my options selected and was just about ready to click purchase on a new 2010 17" MBP and thought I would double check one more thing...Mini display port to HDMI with audio.
    I see many post about this, but most seem to be on 08 models...have the new ones changed? I am more less getting this for my wife to use and she needs it for presentations. I finally got her to go from PC to my old 17" G4 laptop and it's time for an upgrade. The one issue we run into is that files are commonly sent as Power Point, but we got through that with a Mac/Microsoft upgrade.
    I am told the location that these presentations are displayed, plans to get a new monitor and they are looking at BestBuy and such for TV style monitors with the HDMI option. This seems like a cheap way to get away from the projector system they have now that only supports S-video or VGA. I'm hoping that Apple now supplies audio thru the HDMI cable which is in my (limited) understanding the main reason the change over from DVI to HDMI was implemented in the first place.
    If the no audio issue is still a factor, maybe I should put off the new MBP, because I am trying to get away from having to make the trip with her, in order to make sure we have both audio/video. With the projector system they now run, I have to take a PA and output the audio from the headphone jack and then run the S-video to the projector. I am hoping the new MBP will have one cable connection and she be on her way!
    M

    Well for starters, anyone who puts audio into a PPT presentation needs to be taken out back, beaten, drawn and quartered, beaten again, put in a stockade, flogged, then beaten one final time for good measure. The only audio coming from a presentation should be the presenter speaking. The PPT slides are meant to be secondary in nature, highlighting the major points of the presentation as you go along, not be the presentation. Audio and video, even those stupid transition effects, just distract from the content. The people at Microsoft responsible for putting those features into PowerPoint, and thus opening the floodgates for all their competitors, should have all the above happen to them, and then add being shot to the very end of it. It's still far too good a fate for the **** those people have loosed unto the world.
    That being said, I'm under no illusion that this is going to do anything but get worse over time, so here's the deal.
    You need a MDP to HDMI adapter that is designed to also carry the audio signal. But it couldn't hurt to teach her how to ensure that the audio output device is set properly. Just in case. Or, you could do the right thing, and start smacking the people who think it's cute to put all these animations and sound effects into presentations. There are a very select few times when that sort of thing is justified, and 99.99999999999999999999999999999% of the time when one is used, it's not one of those times. Then you wouldn't really have to worry about getting audio AND video. Might be rather cathartic too.

  • 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.

  • 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 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.

  • Thunderbolt mini display port cable to HDMI not registering

    I recently purchased a 6" mini display port to HDMI Cable. When I connected my macbook to my HDMI on my TV the macbook pro does not show the screen as a display option. When I go to system prefrences and under displays the tv is not showing up under arrangements. The only options I have is Display and color, I do not have an arrangement option. My TV doesn't seem to see the computer either.
    I have a thunderbolt port but the cable says it's for a mini display port but works with Thunderbolt, I've used similar mini display cables before with the thunderbolt with no issues. I'm on an early 2011 macbook pro running 10.6.8
    Thanks!

    You may have better luck getting a response/answer if you post the question in the MacBook Pro discussion here.

  • Mini display port to VGA not showing correctly on TV

    I have a new 2012 (June) MacBookPro running 10.7.4 with a 2.5 GHz Intel i5 processor. Graphics  Intel HD Graphics 4000 512 MB.
    I'm trying to connect a Toshiba flat screen TV to the computer via a mini display port to VGA adapter purchased from Apple with the computer. Sometimes I see 5 lines running down the screen. I can get the screen to show on the TV by changing resolutions and refresh rates (1280 x 768 at 60Hz) but the TV shows 5 partial screens on my laptop screen (between those different vertical lines). I feel like I'm looking at the beginnings of an abstract art piece.
    All software is up to date.
    Any advice would be appreciated.

    Called Apple Support and they solved my issue.
    1) Restart the computer in Safe Mode with display attached (shut down and restart while holding down shift key).
         The display showed up without distortion.
    2) Change the display to my desired preferences (dimensions and refresh rate).
    3) Restart computer. ...and it works like a charm.
    Vioala!

  • Connecting Cinema Display with mini display port to macbook pro with thunderbolt port

    I am trying to connect a 27" cinema display (2010) that has a mini display port cable out of the back, into my macbook pro (2013) with thunderbolt ports.  The mini display port cord fits into the thunderbolt port on the Macbook Pro, however the macbook pro does not detect the cinema display and the cinema display does not have any picture on the screen.  The USB plugs in fine and sound comes out, and I have the adapter for the magsafe to magsafe 2 and that works fine, it just the actual display.  Any help would be appreciated!
    Thanks!

    Hello mmholt,
    Welcome to Apple Support Communities.
    It sounds like there’s no video on an Apple Cinema Display that’s connected to your MacBook Pro, and you’re wondering if the configuration is supported. It is supported, take a look at the article linked below for more information.
    Thunderbolt ports and displays: Frequently asked questions (FAQ) - Apple Support
    1. Can I connect a Mini DisplayPort monitor or monitor using a Mini DisplayPort adapter to a Thunderbolt port on my Thunderbolt-equipped Mac?
    Yes. A Mini DisplayPort display or a display connecting with a Mini DisplayPort to VGA, DVI, or HDMI adapter will work just like it was connecting to a Mini DisplayPort connector when plugging in directly to the Thunderbolt connector on your Apple computer. Click here for more information on Mini DisplayPort connections and adapters.
    Also, this article provides a lot of great information and troubleshooting tips that will resolve most issues related to video external displays.

  • 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.

  • 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?

  • Why my new Mac mini  DVI dual link mini display port adapter doesn't work  with my 30"display (LG W3000H)?

    Hello There
    Can any of you advise on the below? Tried to connect Mac mini with a 30" display through a DVI dual link mini display port adapter. For the first try Mac mini go connected to the display, then i've chosen the highest resolution (2560x1600, native) and right at that moment they got disconected. Since then the display stays black. What can be the issue, is it possible DVI dual link mini display port adapter is not compatible with 30"display (LG W3000H)? It works with DVI male-male cable plus DVI HDMI adapter as long as the resolution stays under 1280x800. Any idea is much appreciated.
    Thank you, Vera

    Hi,
    I can report that my Mac Mini Intel Duo connected instantly and without even having to set it up (on the first try) with my 1366x768 native resolution DELL 50" Plasma Display. It's so beautiful that I just want to stand there and fondle my HDTV as I drool haplessly like Homer Simpson with a doughnut in his mouth. Seriously, no problems.... guess I bought the right cable (ebay).
    Before you buy a Duo, make sure you're aware of the airport and bluetooth issues that so many (maybe everyone who tries to use them together) are having. It seems that bluetooth interferes with airport, or maybe the other way around. Anyway, it's messed up. Also, Airport reception is generally VERY poor with the new Intel Mac Mini.
    Despite these things, I still love mine (I now have 2 base stations and an airport express for my powerhouse wireless needs, and an external DLink bluetooth-2-USB dongle solved the bluetooth/airport issues... in my case).
    FWIW,
