Check the USB connection from the monitor to the MP.

yes the usb and minidisplayport are both connected and it can see it is a cinema display, the brightness slider and ambient light controls have just vanished also the keyboard shortcuts arent working ?

keyboard layout

have NO idea if this is the answer, but Apple have changed the layout on the new kb's to accommodate Lion. I know some of the top row keys are different.

I don't think that is it.

F3 = Expose > Mission Control
F4 = Dashboard > Launchpad

I got a new Lion keyboard

I have tried with new and old keyboards

The option is just not there in display settings
