It is possible to overdrive a monitor to the point of burning out components, however if the monitor is properly displaying a picture it is highly unlikely, espically as most newer better monitors are microprocessor controlled and have circuitry in them to block out too high sync frequencies. Waviness sometimes is a result of a 60 cycle AC hum being introduced from an external source, or perhaps a failed diode in the monitor power supply. If it is the latter, you probably want to get it into a repair shop before the damage gets any worse. I've seen monitors wave when placed next to a wall that had a electrical power cable embedded in it. Ted
