Prevent Monitor Burn-In; Adjust Brightness For Room Lighting - Polycom RealPresence Group Series Administrator's Manual

Prevent Monitor Burn-In

Configure when you want your device to go to sleep after a period of inactivity.
Monitors and devices provide display settings to help prevent image burn-in. Plasma televisions can be
particularly vulnerable to this problem. Refer to your monitor's documentation or manufacturer for specific
recommendations and instructions. The following guidelines help prevent image burn-in:
• Ensure that static images are not displayed for long periods.
• Set the Time before system goes to sleep to 60 minutes or less.
• To keep the screen clear of static images during a call, disable the following settings:
◦ Display Icons in a Call: Admin Settings > General Settings > System Settings > Call
Settings
◦ Show Time in Call: Admin Settings > General Settings > Date and Time > Time in Call
• Be aware that meetings that last more than an hour without much movement can have the same
effect as a static image.
• Consider decreasing the monitor's sharpness, brightness, and contrast settings if they are set to
their maximum values.
Procedure
1. In the system web interface, go to Admin Settings > Audio/Video/Content > Sleep.
2. For Display, select whether you want to display a black screen or no signal message.
3. For Time Before System Goes to Sleep, select how long the device can be idle before it goes to
sleep.
4. Select the Enable Mic Mute in Sleep Mode check box to mute your microphones while the
system is asleep.
