Notes
• If your connected computer or audio equipment uses special sound 
functions, such as surround sound, be sure to turn these functions off. 
If these functions are being used with the wide stereo function of this 
monitor, the wide stereo function may not function properly and thus 
not produce the desired sound effect.
• This function is automatically turned off when you use headphones. 
However, in this case, the indication in the WIDE STEREO menu does 
not change.
• The wide stereo function allows you to increase the soundscape by 
converting the analog signals into digital. The sound may be distorted 
depending on the input signal and music. In this case, decrease the 
volume or set the wide stereo function to OFF.
Boosting the bass (bass boost function)
This option increases the bass output of the speaker.
First press the 
M
(+)/
m
