> This is also why you reportedly could aim at a light bulb and never miss. Except IIRC you couldn't because it displayed a fully black screen then a square, and detected a signal edge that must happen within those few frames, or some other implementation to that effect. A lightbulb being constant would not work. LCDs would work but they introduce latency that CRTs did not have, enough so that the check can fail. Even worse if game is emulated. Also I wonder about LCD backlight. EDIT: confirmed by eykanal's link nearby.
