How can I disable Macbook Pro display in closed position?

[tommyn]

I have 2 monitors running off DL and they work fine. The one problem (but not a deal killer) is that my MBP display is still active with the lid closed. I moved it to the far right of both screens under Display Arrangement, but I'd really like to get rid of it if possible. Any thoughts how?

I have the same problem, did not get any answers on Macforums also. Displaylink/Targus/Apple isn't supported yet, But I hope somebody figured it out and can help us.

Hello

Clamshell mode (built-in screen off while the lid is closed) requires a monitor to be connected to the Mac's built-in video output even if other DisplayLink screens are available.

Please also take a look at this article (http://support.displaylink.com/knowledgebase/articles/548400-cannot-use-clamshell-mode-on-mac-os-x).

Thanks,
