We've seen filters applied to displays before for privacy reasons; but a monitor hack to remove the built-in polarizing filter?  That got us interested.

Simply put, the polarizing filter concentrates the emitted light from the monitor into a visible picture, and with this removed, what you have is a white screen.  However, those 3D glasses you have gathering dust you thought you'd have no use for except popping the lenses out and trying the geek-chic look, stick those on and they act as your polarizing filter.  It's an ingenious DIY solution, take a look into how to do it on Instructables by hitting up the source link, and watch the glasses in action below.
