    Before 10.7.2, Mini display to HDMI works just fine. After the update, is doesnt seem to work anymore.

    Totally blank on my Sony Bravia TV.

    I think I may have stumbled upon a clue.


    I just bought Air Display for $10 in an attempt simul-displaying on my iPad 2, and in turn connecting the iPad to my display with HDMI. 


    Well, Air Display, in its first screen, displayed this:  



    In short, if won't work if you upgrade to Lion and have an NVIDIA GeForce 9400M graphics card.


    I do have a late 2008 MacBook Pro running Lion (10.7.2) with the NVIDIA GeForce 9400M.  That machine did not work with the Moshi adapter connected to my Samsung 22" display. 


    My older (early 2008, activated May 22) MacBook Pro running Leopard (10.5.8) with the NVIDIA GeForce 8600M GT works with Air Display -- the Desktop perfectly mirrors or provides additional real-estate -- but the iPad mirroring that Mac's Desktop will not display on the big screen.


    So am I right in assuming that the update works for users running Lion who have *DIFFERENT* graphics cards than the NVIDIA GeForce? 


    If you are still having issues connecting your MacBook to a display using a Mini DisplayPort-to-HDMI adapter, LIST YOUR GRAPHICS CARD. 

    Let's see if we can get this fixed.

    This is what worked for me....I plugged incable to computer and my LG 42 inch 1080 HDTV. I aslo received the flickering screens....then I went to Apple icon> System Preferences>Display>Arrangements>Select Mirror displays. This worked great for me Hope this helps!!!!

    Well, I got the early 2011 Macbook Pro and it should support Mini DisplayPort to HDMI adapter (From Apple Store). The graphic card used is Radeon HD 6750M / Intel Graphics 3000.


    Before 10.7.2, everything working fine. After the update, the adapter doesnt work anymore.

  • kaptajnknas Level 1 Level 1

    Still having the same problem. When connecting the mini-display adapter, I get two blue screens and then nothing.


    I has worked for some time until I upgraded to Lion - at least thats what I think. And it seems that there are many with the same problem.


    However, I have rolled back to 10.6.8 using install CD and an old safetycopy via Timemachine. That didn't fix it.


    I have NVIDIA GeForce 320M


    (and macBook pro 2.4 Ghz Intel Core duo 2)

    Mines doing it too since upgrading to Lion! 2011 Macbook Pro 13.3" LG 42"

  • Timosay Level 1 Level 1

    I'm having this issue.  I have been able to get it to work in the past, but I'm not sure what update or changed that made it where I can't connect my LCD TV.  The MacBook doesn't even recognize the outside source.  Very frustrating because it doesn't seem to have a logical explanation as of yet.  Please help!


    Early 2011

    Graphics  AMD Radeon HD 6750M 1024 MB

  • dapoetof2002 Level 1 Level 1

    I am having this same issue ever since installing the newest update. My system is running on Snow Leopard. I have an adapter that hooks to the HDMI cord which was working fine before the newest update. Whatever the issue is I hope its resolved soon.

  • cmamun01 Level 1 Level 1

    Not sure if anyone has figured out the problem - but I have the Kanex Mini DisplayPort to HDMI Cable - I went to the apple in the left corner - System Preferences - Displays - Arrangement and Clicked the box "Mirror Display."  Then it worked fine....everything I do on the computer comes up on the TV now.

  • afiser Level 1 Level 1

    We should go viral with this. It's literally a feature that should work no matter what, yet Apple continues to ignore.  Maybe once they get some bad publicity they may think about attempting to fix it or atleast giving us a reason as to why it is not working, this is ridiculous. Imagine how fast a fix would come out if this somehow managed to get front-paged on Engadget or similiar. This is a feature I'm sure many people would love to use but still cannot because of bad hardware or software, and it's ultimately Apple's fault for the most part.

  • kaptajnknas Level 1 Level 1

    My problem solved!!


    I tested my macbook and my cables at my friend sith a similar setup. He is running Lion i am running Snowleopard. Both macs were giving to blue screens, and then nothing when using my HDMI adapter. Then we swithed to his adapter, and both setups workes.


    I found out that it was my minidisplay-hdmi adapter, that had stopped working - unfortunately it stopped during the same periode where i upgraded to Lion, so naturally I blamed the upgrade. Didn't even consider that the adapter should have stopped working. It had been working fine for 6 months. I even tried rolling back to Snowleopard - with no result of course.


    I'm not suggesting this is whats going on for all pf you - but it may be worth to try another adapter.


    I have a NVIDIA GeForce 320M

  • flyhighusa Level 1 Level 1

    Same problem here. displayport-HDMI adapter replaced after 10.7.2 upgrade and it works again. Seems to be the solution although it is VERY coincidental that many many users have this problem and their adapters "give out" at the same time.

  • ian1946 Level 1 Level 1

    Im having same problem. Worked fine when i was in US. Now im back in UK no joy! Only differance using Amazon basic HDMI cabel. how do i know if its not that? Should i go for AVI?

  • pvalderama Level 1 Level 1

    I found a solution


    Using a Macbook Pro late 2011.


    Using a Belkin Mini DisplayPort to HDMI Adaptor


    TV: Sony 3d HDTV





    Plug HD cable to HD adapter


    Go to System Preferences > Displays>


    If you look at your TV, a Display should show up for your TV.


    a different display window should show up on your laptop.


    The display is too big for what is seen on the laptop. So to view anything on your tv

    drag any window on your laptop that you want to view on your tv to the right of your laptop screen..

    and it should display on your TV.




    go to system preferences > sound > output > select your tv as device



    Hope this helps everyone.
