Though scanning voltages go up. And if EHT is generated by the horizontal oscillators, that goes up as well. I've seen sets go "bang!" when the horizontal frequency went too high, I wouldn't rule out the same thing happening with a computer monitor. Particularly if you have one that doesn't do out-of-range detection. -- (This box runs FC6, my others run FC4 & FC5, in case that's important to the thread.)
