Hitman6267 wroteYes it does, it means it depends on your UPS. If you check the UPS' voltage upon turning it on and the voltage is O.K. you have nothing to worry about.
it does not, this answers the turning on part, which i did not ask, my ups is fine during turning on,
a good answer would have been "no turning off wouldn't harm the monitor but turning on might because...etc"
i need someone to confirm this though
