    Hello everyone,

    I just bought a brand new 13" macbook pro i5, it works absolutely fantastic.
    There's only one thing i'm not happy about:

    If I connect an external monitor to it (both my sharp 32" via hdmi and my 19" samsung via VGA) it starts to lag! Even on my MBP screen! Is this a lion bug? I noticed I'm not the only one who has this problem.

    I've got a 4 year old HP notebook which doesn't have a problem with both monitors and now my brand new expensive Macbook does. I already renamed to "AppleUpstreamUserClient.kext" and tried to run it in safe mode but with no results.

    Oh and if I try to logon to discussion.apple.com i get this:

    We're sorry.
    We're having a problem processing your login.
    13: Jive ind not found or set. Unknown status code: 13

    Can somebody help me out?

    Note: A colleague of mine has got the early 2010 macbook pro and has no problems with his external display(s) on Snow Leopard.
