    I confirm 10.8.2 did not fix the same issue with my rMBP.

    Neither did the rMBP EFI Update 1.0 released today.

    Just wanted to say that i have the same problem, although with a macbook pro mid 2012. Ill exchange my mini-dvi <-> hdmi adapter tomorrow against an mini-dvi <-> dvi, hope itll help.

    I know this is a thread for Macbook Airs, but I know a lot of rMBP people are having this problem too.  I'm having this problem with my new rMBP and an HP LP2475w.


    I have tried HDMI direct into my monitor as well as a mini Displayport to Displayport on the monitor.  My mid-2009 MBP works fine with this display using the MDP to DP cable so I know it's not the cable or the monitor.  I'm also running Mountain Lion 10.8.2 on both machines.


    I ordered a different HDMI cable and a few different adapters.  I think I'll try going from HDMI to DVI on my monitor to see if I can get that to work.  I really wish Apple would fix their drivers but I really need this external display and I want to retire my 2009 MBP from daily service.  I'll post back when/if I figure out at least a temporary solution.

    Same problem here, Moshi DP->HDMI adapter, MBA 13 mid-2012.


    The funny thing is that I've borrowed a no-name 5$ cheap DP->HDMI adapter from a friend and it works perfectly fine. Unfortunately the guy he bought it from does not have these aymore in stock and the new ones he is offering have the same problem as the Moshi adapter.


    Another interesting thing is that the Moshi adapter works fine with an old MBP.

    I have the exact same problem with my 2012 13" MBA.


    I tired 3 different Displays with both, HDMI an DVI Adapters.


    Interestingly I discoverd that Mountain Lion doesnt even give my a custom display color profile when connected via HDMI. VGA seems to work better but still isn't satisfying.


    I hope that this problem will be fixed soon!

    Just wanted to report back with what I finally got to work on my monitor with my rMBP:


    HDMI => DVI adapter &p_id=2029&seq=1&format=2


    HDMI Cable &p_id=9427&seq=1&format=2


    You could probably get away with a cheaper HDMI cable but I wanted something that looked nice because I'm obsessive about those sorts of things.

    Yesterday bought MiniDisplay -> VGA adapter and now testing my Philips 23" external monitor with MBA. What a relief for my eyes

    Will stay on VGA adapter, while checking HDMI output after every major Apple MBA update - hope the Apple will fix it some day (not the year )

    Tried the HDMI to DVI adapter trick and...

  works! Everything looks as it should. That is all very strange.

    Anyone from Apple here??? What's the point of this forum if no one from Apple support is loonking into it?!?!?

  • JiveMasterT Level 1 Level 1

    The only thing I can imagine is going on here is some subset of monitors on the market aren't following some standard that Apple hardware is upholding strictly.  When you switch to DVI, there is some digital conversion that alleviates the funk.


    My rMBP actually works fine whenever I plug it into an HDMI TV.  It's just this one monitor that it seems to have a problem with.

  • gubble Level 1 Level 1

    JiveMasterT, I don't think you are right.

    It would be funny if Apple are following "some strict standard" now but with previous MacBook models they decided not to follow them and just make them work with any monitor

  • JiveMasterT Level 1 Level 1

    Maybe.  Regardless, I've always had problems with this HP monitor and my Macbook Pros using Displayport.


    Funny enough, I bought this HP monitor because my Dell 20" monitor wouldn't work at all with my 13" Aluminum Macbook.


    Have a look at what Apple says about the VESA standard regarding adapters, HDMI, and Displayport:


    Interestingly, my old Macbook Pro didn't support audio over Displayport or HDMI.  My monitor definitely doesn't support audio over HDMI.  This weird problem we're all having appears to go back to 2010 or 2011 just by skimming some forums.  That also seems to coincide with when Apple started doing audio over Mini-Displayport.


    Could all just be a coincidence though.

  • gubble Level 1 Level 1

    I don't know either and don't want to argue but it would be surprising if Dell and all the other display manufacturers didn't follow the VESA standards...

    Windows And Linux Works perfect...

    This really is the single most important point:


    "Windows And Linux Works perfect..."


    It's OSX baby.
