    Exactly the same problem here.

    MBP screen goes black when i connect the hdmi to a panasonic 1080p TV. The TV remains with no signal (blank).

    The only thing you see is a big arrow on the MBP.  The arrow looks normal on the HDTV.

    I have a single pixel lit on my MBP.

    It worked fine with Lion.  Now it doesn't.

    I have no Arrangement tab in Displays.  (It might be there, but if it is it's on the phantom display to the right of my MBP which I think is there because the cursor seems to go off of the screen.)

    A VGA Thunderbolt adapter worked fine last week.  I reset my PRAM just in case some setting got stuck.

    Is there any update from Apple on this?  I'm trying to connect my Macbook Pro Retina with to my Panasonic 46" and it recognizes the hdmi connection then just drops to a black screen.  Oddly, it seems to work ok on my Panasonic 42" tv for whatever reason.  It worked fine until the last Mountain Lion update. 


    I would really love to hear some type of Apple update on this...for a $3000+ computer there have been quite a few issues and I haven't seen much in terms of acknowledgment that these issues are being worked on.

    While troubleshooting my DVD Player unexpectedly quitting, I booted into safe mode and restarted, reinstalled 8.2, archived and re-installed OSX, reset the PRAM, and reset System Management. One of those processes fixed my HDMI mirroring issue.   My DVD Player is still being researched.

    if you close the cover, image works fine, but you do not have access to keyboard and trackpad

    i think this is a software problem, because, first works good

    Same problem here. Trying to connect over HDMI to an external monitor (HP 2211f) with 1920x1080 - 60Hz but the monitor don't find any signals through the HDMI port. Any solutions out there?

    I'm having similar issues with my MBP Retina but they seem to have started after I did the recent EFI firmware update.  Before that, my HDMI port worked fine.  Now, when I plug my 56" Haier display (1080p, 120Mhz) via HDMI, I get a black screen on the latop and TV with random, low res screen updates in small blocks at a time under the cursor.

    yesterday for the 1st time I tried to connect my MBP 15" Retina Display to a Sony TV Bravia KDL-26M 4000 through HDMI but it didn't work. I got a 1st messages "Invalid Format"  and after NO signal on TV and the computer monitor became black.


    Today I went to visit a Genius at the Apple Store and as soon as he connected the computer to a TV, with the same cable,  it worked... Just plug'n'play.


    I came home I tried again:


    1.- I connected the HDMI cable with TV Off

    2.- I connected the HDMI cable with TV On

    3.- I disconnected the power cable of the TV and I waited 30"/45" and reconnected

    4.- I turned Off and On the computer

    5.- I plugged In and Out severals time the HDMI cable, and I tried the 2 different ports

    6.- I even tried to change the resolution on the computer but on the MBP Retina Display you can't do to much

    7.- an many more


    but NO success, still got  the messages "Invalid Format"...


    I'd like to add that the other devices connected to the same HDMI ports on that TV are working, means the TV is working


    some help will be appreciate





    MacBook Pro, Mac OS X (10.7.5)

    I wonder why the geniuses in Apple are sleeping on this issue as there are forums upon forums with the same issue... It's about time to release some kind of bug fix APPLE!

  • djjimson Level 1 Level 1

    same thing overhere... used to work before... now nothing... :-((((

  • johnnyboymcgee Level 1 Level 1

    I have encountered this problem in the last week too after running the latest software update. HDMI out used to work fine with my LG 32LH2000 but now I just get two black screens (TV and MBP Retina) with only the cursor visible.


    Apple need to pull their finger out and fix this, this machine wasn't cheap.

  • Nathaniel Chadwick Level 1 Level 1

    II've been having the same issue. MacBook Pro 2009? Running Lion and 46" Vizio. Everything used to work great! Now---zilch. Apple? Bueler?

  • donaceli Level 1 Level 1

    I bought a cable MDP (male) to HDMI (male) by Neet from amazon for £11 and my broblem is sorted for now. I've been using it for 2 weeks now and everything seems to work just fine.


    Good luck!

  • johnnyboymcgee Level 1 Level 1

    I fixed my problem by trashing all of the files I could find on my system (they were located in Macintosh HD > Library > Preferences). After that I did an NVRAM reset, then my problem was solved. Here's a link explaining how to reset the NVRAM:



    NOTE: You may have files in your user profile library preferences too, trash these as well. You will have to go to the menu bar and select Go > Hold down alt (this will reveal your user profile library) > Library > Preferences then locate the files (if they are there, I didn't have any but others have said they may exist).


    Hope this helps, it worked for me.

    Seems I'm so lucky (at least at the moment).  I have 13" retinal display MBP, I plug in the HDMI cable to TV and it worked fine.  But the second time I plug in, the TV screen turn green although the connection is established on computer.  After several unplug and plug again, it worked again.


    It seems that the MPB is not so stable and probably not well developed for HDMI connection, because I haven't heard about this kind of problem happen on all other AV devices.  Another factor may be the different brand of TV that may not be compatible with MBP display card.  Hope Apple can do something (?update of firmware) to correct it.
