It simply engages BW/reflective mode when you dial down the brightness to off. Alt-brightness up and Alt-brightness down on the XO get you to reflective mode (and back) in one strike. In normal use, colour mode is still quite usable (though not as crisp as BW) in bright sunlight, it's just that the colours desaturate as the reflected light gets brighter. Note the backlight goes through the colour refractive screen magic, even in BW mode, so it's not as sharp as with the backlight 100% off and just using reflected light (though BW + backlight does still look slightly crisper than colour mode, to my eye, like sub pixel sharpening tricks on conventional screens). --Gary > -Wade > _______________________________________________ Devel mailing list [email protected] http://lists.laptop.org/listinfo/devel
