The input mode may change in the following cases: - When a computer is in standby mode. - When video play is stopped with a playback device. Power LED flashes red.

This varies depending on the setting.) The monitor makes a cracking sound. • You may occasionally hear a cracking sound from the monitor. This happens when the cabinet slightly expands and contracts according to change in temperature. This does not affect the monitor's performance. E 54
