Hi,



Just installed the above update, and now my second monitor nolonger works. I plug it in, my MBP detects it and expands the screen, but the MBP never sends any signal to the monitor.



Any suggestions? I'm quite new to the OS, and I'm not sure which logs to look at in Console.

Again, any help would be appreciated, as this is quite a pain



Thanks



Alex.

    Go to the Apple menu, to System Preferences, and open the Display pane. Click the button labelled "Detect Displays".



    If that doesn't help, try resetting the PRAM, by restarting the computer, and as soon as the machine begins to power back on, just as it chimes, hold Cmd-Opt-P-R until it chimes a second or third time.
