Updated my rMBP to 10.8.4. The laptop rebooted, and the external display is not displaying correctly. How can I fix this?

 

The monitor has never had problems until immediatly after the update. The monitor attempts to display 1920x1080, but is offset. Part of it is off the screen, and is not horizantally long enough to fill the screen anyway. (Black bar on left side).

 

Bootcamp Trial

Booted into Windows 7 64bit

Monitor works fine, highest available resolution is 1280 x 1024.

 

Tried to set Mac resolution to 1280x 1024, works, but this is noticably less resolution than I had originally, before the update.

 

Specs

Retina Macbook Pro

LG external monitor: FLATRON W2343T

Thunderbolt to VGA adaptor

 

Thanks for any help you can provide.

OS X Mountain Lion (10.8.4)

    Yes, I have the same problem with my Macbook Pro. The external display isn't filled and is offset. I have tried re-calibrating the screen, but to no effect. I hope Apple fixes this soon.

    It's a long shot, but you might try

     

    Resetting NVRAM / PRAM

    Does the resolution appear properly if you boot the system into Safe Mode by holding the Shift key after hearing the boot chimes at startup?

    When booting in safe mode, the display changes to 800x600 and when I set it to 1920x1080, the same problem persists. I will try the NVRAM/PRAM reset.

    Same problem with:

     

    MacbookPro Mid 2009

    Asus VE247 External monitor

    Minidisplay port to VGA adaptor

    OS X 10.8.4

     

    Only happens with VGA resolution 1920 x 1080, others resolutions or with HDMI adaptor works fine.

    In windows 7 with Bootcamp works fine.

    Downgrading to 10.8.3 with Time Machine resolve the problem.

     

    I tried with no results:

     

    - Change to the other internal GPU (NVIDIA GeForce 9400M to NVIDIA GeForce 9600M GT)

    - Reset PRAM

    - recalibrate screen manually.

    Yes, I also have a Macbook Pro Mid 2009 with a Dell U2410 monitor and the same problem exists.

    If you're using a VGA input, you're using an analog input, and you would have to make the adjustments using the monitors screen adjustment controls. Use a DVI (digital) connecton if available.

    I am experiencing the same issue on my MacBook (late 2008) which is connected to a Dell U2211H via mini-DisplayPort to VGA. I have found that I am able to re-establish full screen and full resolution by sleeping the computer and then waking it again. Unfortunately this method is not always effective so sometimes it requires a single sleep while in other situations it is multiple attempts before things are back to normal. Very odd behaviour.

    Even using the monitor adjustment controls (manually and auto resize) the screen doesn't fill.

    I tried with other monitor (PackardBell) and the issue is the same. It´s only  happens with 1920x1980 resolution and VGA adapter. DVI and HDMI works fine.

    I had a very similar problem. Contacted Apple Support and they are still in the accumulating data mode. I ended up reverting to a time machine copy that was in 10.8.3.

    I am having the same issue, chopped off about 2 inches from the left and 1 inch from the right.  If I change from anything but 1920x1080 60hz, works fine (but have screen refresh lines).  I only have a VGA option as I am using a switch box.  Worked fine until 10.8.4.
