[to] pulse width modulat[e] the different digital lines during the normal pixel period (or slightly longer than normal..." How well does this work? It seems to me that halving a pulse to a pixel would require higher bandwidth amps in the monitor. Perhaps the smaller pulse width isn't so small that it's filtered out. As for "slightly longer than normal", how much wider can the pulse be? If it were too long, wouldn't the beam just strike the shadow mask? Or, don't the normal pulses paint the entire phosphor dot? harold ravlin {ihnp4,pur-ee}!uiucdcs!uicsl!hr
