Why does white on a TV screen cause audible buzzing noise?
It's obvious more on an all-white screen, but even small amounts like captions. It seems like it's been this way for decades, through CRT and on to plasma HDTV screens.

Or, alternately, if no one else has noticed this, why can I hear white and how can I use that superpower to fight crime?
