because if it was a perfectly good 17" monitor it would have been a waste, a broken 15" or a broken 17" would seem much less "wasteful"
anyways, I hope it was a broken 17" LCD
...thanks to the guys at Viewsonic for giving us a dead unit from their stock to mutilate.

P.S: It's Pythagoras for the CRT pixel calculations and there's a typo in the Future section: "Arguably, there is not much of a future a all for CRT technology"
Not advisable unless you like the feeling of 30,000V across you ;)

The two filters are exact opposites of each other. As the light from the light source behind the first filter comes in, the filter effectively whites it out - which means that if it was to pass through the liquid crystals with no interaction, the filter on the other side would polarise it back to black, leaving no colour being emitted. In fact, alternate current - leaving the crystals 'dead in the water' - is how black is created on a panel.
