    Formatted my MacBook Pro and clean installed Snow Leopard after I lost connectivity to any external monitor I plug in to my MBP. I noticed that as soon as I restarted with the Snow Leopard DVD, I regained the connection with my external monitor. After format all was well until I updated all to the way it was. No problems showed until I loaded the recent update of Snow Leopard.

    Does anyone suffer from this?

    Does anyone know a solution?

    I am starting to see isolated posts in the internet from desperate people.:confused:

    interesting...

    I did some PRAM reset and the screen is back. I will see how it behaves... I went through a whole day of reformatting and putting all back in my MBP. I would reformat again, or just stay on 10.5 until the matter gets resolved.

    strange, i've 2.93GHz MBP and using DELL 24" connectd directly from mini-display port to display port.

    no issues.

    are you running latest 10.6.2 ??? Updated firmware ?
    reset PRAM is a good idea.
