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.
