    Can one of you guys with an newer (last year or so) iMac do a quick test for me?

    When you turn your screen brightness all the way down, does the screen actually go black or is just dimmed?

    Have used both 21 and 27" iMacs and they do not dim to even near to black. In fact they do not dim near enough for a room with low light.

    Wish there was a way but it could be a limitation of the LED lighting

    Thanks.. I was wondering because my 2009 MacBook Pro does go to black with the brightness turned all the way down. I wonder why the iMac behaves differently..?

    Notebook vs. desktop. Every Apple Notebook i've ever used was able to totally turn of the back light where as the iMac and cinema display never can go below a certain brightness. It's all about power consumption. A notebook user may want to totally turn off backlighting where as a desktop user just needs to dim it enough to be comfortable viewing in low light situations.
