How to make macbook output to external monitor only

[Combat squirrel]

As title, im trying to get my macbook to output to my 2407 ONLY when the DVI cable is attached, currently it only seems to let me either mirror or span, I cant seem to see the option for this (force output to one monitor only, i.e. the external one), I maybe being daft! lol but any help is appreciated

Close the lid on the macbook and then click the mouse or something to wake it up from sleep, it will then be outputting to the other monitor. Then lift the lid so air can get in.

Thats the only way i know..

I turn the brightness right down Haven't tested a hot corner though, to sleep the display. Not sure if that will sleep the current or both displays.

I asked this a while back, and found DD's solution the only feasible one.

What? turning the brightness down forces one monitor to display on external cable ? Really ? thats bizarre,lol

No, but my method works. Don't see why people have a problem doing this as it takes 10 seconds to close the lid and wake it up from sleep using an external mouse/keyboard.

Well yeah but why on earth apple cant add an option to just output to one monitor only is beyond me.

just turn it on then close the lid - or close the lid then move you mouse or plug somthing into the usb
