Does anyone else have this problem?  I've seen similar issues raised, but so far can't find a solution to my particular issue:


MacBook Air Mid 2013 (ordered Jan 2014)


- 1.3GHz Intel Core i5

- 8GB 1600MHz DDR3 RAM

- OSX 10.9.1 Mavericks.


When I connect my MacBook Air to any monitor (well, I've tried three monitors: Benq, NEC and Samsung) the monitor will not detect an attached computer. The MacBook also does not think it's connected to an external display.


If I connect via VGA cable, it works fine most of the time*, so the display port seems to work only for VGA and not DVI.


I am using mini display port adapters (DVI and VGA) purchased from the Apple Store.


The adapter for the mini display to DVI works fine, since I can get my 2009 MacBook unibody to connect to an external display via DVI without issue. So it's not the adapter, or the DVI cable.


I have tried resetting the System Management Controller for my MacBook air but it does not work.  No matter how many times I reset the computer (Hard reset, Soft power down, SMC reset) I cannot get it to connect via DVI.


Has anyone experienced this issue, or seen a resolution for it?


*The only other symptom I get periodically, is that after being disconnected from a VGA monitor, the computer will periodically (about 2/5 times) not connect to the VGA monitor either without a reboot.   However it will connect most of the time, and ALL of the time after a reboot.


Thank you

MacBook, Mac OS X (10.6.2), Basic White

    Welcome to Apple Discussions


    Have you found that connecting the monitor before booting, and disconnecting it after shutdown has any effect?


    Have you tried different adaptors, or tried the adaptors on different Mac's? (Only to rule in/out faulty adaptor)

    Thanks themachead: I have tried the adaptors on different macs, as I indicated in my post.  The adaptor works fine with a different mac


    Yes, I have also tried starting up with the monitor connected, and disconnected.


    I just got off the phone with Apple Care. They couldn't solve my issue through normal means, but during one attempt, we closed my MacBook Air while it was connected to the external display, with my Magic Mouse and Apple Keyboard connected via Bluetooth.  The external monitor did not come on.  However when I opened my Macbook Air's screen, we saw that my Mac had crashed and prompted me to reboot. When it did, the external monitor worked.  I have been able to disconnect and reconnect the monitor and it seems to be working now.   I will see what happens after a few attempts.

    Mavericks is revealing a lot of "undiscovered features" as the M$ folks used to say. I think it wise you opend a case with Apple, and perhaps the rumored 10.9.2 update will change this.
