24" LED and MBP problem

[logicpro7]

I have a 24" LED and a new 17" uMBP and when i use it in clamshell mode and turn the brightness fully down on the keyboard the screen still has some brightness.

It does not fully turn off. Any ideas?

I don't believe mine ever just went black. Does it go black when not in clamshell mode?

These displays do not go black when the brightness is turned all the way down. The aluminum ACD's didn't either (I have the 30" and it doesn't).

If you want the screen to go off, what I did is I assigned the bottom left hand corner in Expose to "Sleep Display." Whenever I need the screen to turn on, I just flick my mouse down there and it turns off.
