    Here's an interesting experiment.....grab a pair of polarized sunglasses, put 'em on, and check out the 24" screen. It's almost completely black and unreadable. Tilt your head to one side or the other and it becomes readable...

    It looks like the glossy screen is polarized in one direction. I wonder why???

    I did not try tilting my head, but yeah, with polarizing sunglasses I could not really see much on the screen. 20'' does not exhibit the same behavior.

    Because if you polarized in two orientations you couldn't see it from any angle... ;)

    All LCD's are polarized. Wouldn't work otherwise. http://electronics.howstuffworks.com/lcd2.htm
