Think you need to do some research on how LCD's work. They're electric field devices. Yes, there is a relationship between electricity and magnetism, but that ain't what's in play here. Given your description your position, I suggest you refrain from implying that you understand quantum mechanics. > > Heck, even if the crystals somehow aren't sensitive to magnetism > there's a whole array of little teeny transistors behind them that certainly > are.

Yep, given enough magnetism, you can probably make the universe implode. That ain't in play here either. Let me add that the CRT display IS significantly affected by magnetic fields.
