    Actually, I had an email during the summertime from one of their AppleCare reps wanting to collect info from me as soon as I started posting.  We were trying to set a time to talk over the phone, but I had thrown away the burnt adapters so they said "nevermind."  I sent this particular rep an email about two weeks ago saying I now had multiple dead adapters set aside, but got no response.

    Hi All,

     

    Just writing because I think a lot of helpful info has gotten lost in older posts and I wanted to add this experience in case Apple can use it.

     

    I struggled with the same issue of not being able to see my Macbook Pro on my Samsung LED TV (using the HDMI to mini display port adaptor) until I changed the display preference, for instance 800 x 600. (I can't remember which setting I chose but there was only ONE that would work  of all of them.)

     

    It was a permanent fix, although over time I ran into issues with grainy quality in the picture and sometimes scratchy feedback which I attributed to the HDMI cable going bad.

     

    However!!! I just got an Apple TV and the same HDMI cable works seemlessly with it and the picture quality is perfect. The Apple TV is a great option but was similarly hard for me to set up until I discovered how to change the channel setting.... All the channels were black, black, black... then I got two channels which were scratchy and grainy the same as before... then the next channel was perfect. I think it was 1024 x 768, but don't quote me on that.

     

    All of this is to say I think it's a problem with the screen formatting.

     

    Good luck!

    My MDP-HDMI adapter works perfectly, as does my HDMI cable, so does my MBP! I tested by booting into my WindowsXP partition and I was able to enable my TV as extended desktop, full 1080p resolution and quality, via my Mac's miniDisplayPort, my Moshi mDP-HDMI adapter, a 15' HDMI cable, and a Samsung HDLED TV. The exact same setup that worked for months on my OSX 10.9 installation... until recently. About two or three weeks ago my OSX partition stopped seeing the TV whenever I plug in the mDP adapter (normall it just switches right over, no problems). I have tried every solution and isolated the problem down to an OS issue. At this point in time, nothing has worked and I still cannot use my TV as an external monitor in Mac OSX 10.9.1... but WindowsXP works just fine (at least that's where all my Steam games are installed).

    In my opinion apple are doing it purposely to make mac users invest in apple tv products. As mentioned many people are able to boot into windows and get the adapters working. Its a software issue that they decline to resolve.

    Aaaaaand my Monoprice mDP to HDMI cable just died.  I opened the App Store to updated Pages, iMovie, and Keynote.  I restarted the computer afterwards and now have no video output through this cable.  I'm not pointing the finger at those apps because this has been going on so long, mind you.  Multiple shutdowns and restarts, PRAM resets, openings and closings of the lid...no response.  Open Display Preferences, Detect Monitors, nothing.  But hey, at least the thread made it past 1,000,000 views!

  • wcs0816 Level 1 Level 1 (5 points)

    I grabbed the spare mDP to HDMI adapter and HDMI cable I keep in my office desk drawer and I'm up and running again.  One thing I noticed when unplugging and reconnecting the now-dead mDP to HDMI cable is that I get a pretty pronounced buzz emanating from somewhere inside the MacBook for about 1-2 seconds when the mDP side of the cable is plugged back in.  I get this buzz whether or not the HDMI cable is plugged into my monitor.  So strange.

  • wcs0816 Level 1 Level 1 (5 points)

    And one more mDP to HDMI cable has failed.  So far that's two for 2014.  Same MO - randomly dies afer being plugged into the MacBook Pro with a faint audible buzz from within the laptop.

    Well, I also got this problem, kind of. One day I woke up and it just stopped working - "No Signal" on the display, and on the setings of displays in Mac OS there is no external display detected, also when pressing alt/option key.

     

    I was trying to isolate the problem, but for now I'm nowhere. I will list what I did, maybe someone with enough brain will find a solution.

     

    Initial stuff:

    1) MacBook Pro 15 Mid 2012

    2) Rocketfish MDP to HDMI adapter

    3) Samsung UE40C6500EU TV

    4) Mac OS X Maverics

     

    Facts:

    1) Tried different cables - no effect

    2) Tried resetting PRAM and SMC - no effect

    3) Connected other devices (Dell lapop, DVD player, Hi-Fi) VIA the same cable (no adapter) and port on TV - works

    4) Connected my MBP to other TV via the same cable and Rocketfish adapter - WORKS

    5) Connected my MBP to THE SAME MODEL of Samsung TV BUT a different TV (my father's TV) - WORKS

    6) Reflashed my Samsung TV with all available firmwares (requires hacking a TV to get root access) - no effect

    7) moved com.apple.windowserver.plist and com.apple.windowserver.some_numbers.plist from local and global Library - no effect

    8) booted into safe mode - no effect

     

    I'm not a person who knows Mac inside and out, so maybe I missed something important. Anyway with this my little research I am frustrated I cannot get this working. For me it seems my Mac stores somwehere some magical data about MY TV that just says - I WON"T WORK WITH IT.

     

    I've read almost all posts in this thread and in many other places as well and just cannot understand WHY Apple just does nothing with that. Sure we can tell it's all about money, but this is a MASSIVE problem.

     

    Cheers

    I've had the same problem ever since the Jan 13th 10.9.1 OS upgrade and the Thunderbolt firware update on the same day.  I have tried multiple MacBooks, multiple TVs (LG, two Samsungs and a Sony) and multiple converter cables. Any MacBook with the upgrade fails to properly connect and display the screen on the TVs. When I try any Windows based device or a Macbook running windows it works just fine. 

     

    Whatever Apple has done in the firmware upgrade and/or the OS upgade has crippled the Thuderbolt to HDMI connection.  Not sure if it has anything to do with selling more AppleTV devices, but they need to fix this issue. The thurderbolt port is there for a reason and it just hasn't worked since Jan 13th.  Very frustrating.

  • wcs0816 Level 1 Level 1 (5 points)

    I've actually got an appointment scheduled at the Apple Store in Raleigh, NC for this evening to have them take a look at my MacBook Pro.  I've got a mixture of 11 adapters and cables that I'm bringing with me that have all been rendered useless since the Thunderbolt 1.2 firmware update.  Just hoping they don't ask to send my MacBook away and leave me stranded without my work PC.

     

    If anyone else sees this, please let me know if you hear the buzz from inside the MacBook when you plug in your dead adapters.  You will need to be in a quiet room and get your ear close to the keyboard, but I would be interested in knowing if any of you hear it too.

     

    Thanks!

    I needed to plug my external HDMI monitor (LG L246WP) into my Macbook Pro 17" (Thunderbolt to HDMI Cable) so I could use Color. Whereas it worked fine before, of course now it doesn't. I went through most of the posts here and nothing worked for me.

     

    Then I found that if I set the resolution in DIsplay Preferences to 1080i for the external monitor I can get Mirroring to work, but when I go to the expaned desktop, the 1080i resolution isn't there and the external monitor stops working. The 1080i setting is not the correct solution either - this monitor does 1920x1200 when connected to my MacPro 1,1 using a DVI to HDMI adaptor.

     

    I think there is an bug/mistake in Mavericks that doesn't reconize the proper options for HDMI TVs and Monitors.

     

    COME ON APPLE TELL ICON TO TAKE A LEAP AND SPEND SOME OF THAT $PARE CHANGE ON FIXING THESE PROBLEMS!!!

    Well, I went to the Apple Store this evening and the answer I got at the Genius Bar was pretty much what I expected going in - "Replace the logic board for $561."  While the gentleman that helped me was very nice, he technically had no evidence that the logic board was actually bad, and even admitted that he would expect to see other problems manifesting if that was actually the case.  And despite that fact that I brought along 7 dead adapters, they actually had no equipment in the store with either an HDMI or DVI plug with which to test them.  So, I've come up empty-handed yet again with my issue.

    You haven't come up empty handed at all.

     

    You've been presented with a choice. If a new logic board solves the problem then we all know there's something on the logic board that's causing the problem.

     

    If that's the case, we can your case as an example to have our logic boards replaced too.

  • wcs0816 Level 1 Level 1 (5 points)

    It wouldn't worry you at all that there is no actual test to perform to determine if it is, in fact, the logic board?  Not even a little?  You'd be comfortable with "Eh, let's roll the dice and see if this does it!  That'll be $561!"
