I used to think the same thing, but I learned it's not possible in the 
current hardware.

this is the one drawback to the fantasic screen, any light from the 
backlight that gets through is colored by the screen. it can be made to 
appear white by allowing all three colors through, but it's still colored.

this means that you can't get high resolution mode with the backlight on.
