Hearing Audio Confirmation When You Dial

Adjusting for Room Lighting 

If your system administrator has allowed access to user settings, you can use 
the backlight control to adjust the brightness of the video that the main camera 
sends to the Polycom HDX system. Adjusting this setting can be helpful when 
the room arrangement results in strong light coming from behind the people 
in the picture. 

To turn backlight compensation on:

1

Select System from the Home screen.

2

Select User Settings from the System screen.

3

Scroll to Backlight Compensation and press 

 on the keypad to enable 

the option.

Press Home to save your change and return to the Home screen.

For information about adjusting the brightness of the Polycom HDX 4000 

monitor, refer to 

 on page 

.

Because backlight controls adjust the built-in camera, these controls do not make 
content from a computer appear brighter.
