The input mode changes automatically.
•  When the AUTO INPUT CHANGE is ON and no signal

  The input mode may change in the following cases:

When “AUTO DIMMING” is displayed.
•  When the internal temperature of the monitor rises
excessively, the brightness of the backlight automatically 
decreases in order to prevent a further temperature rise. If 
you attempt to use

the monitor is in this state, “AUTO DIMMING” is displayed
and you cannot change the brightness.
•  Remove the cause of the excessive temperature rise.
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.
