Flash the screen for alert sounds

Your computer will play a simple alert sound for certain types of messages and events. If you have a hard time hearing these sounds, you can have either the entire screen or your current window visually flash whenever the alert sound is played.

This can also be useful if you're in an environment where you need your computer to be silent, such as in a library. See Choose or disable the alert sound to learn how to mute the alert sound, then enable visual alerts.

  1. Click your name on the top bar and select System Settings.

  2. Open Universal Access and select the Hearing tab.

  3. Switch Visual Alerts on. Select whether you want the entire screen or just your current window to flash.

You can quickly turn visual alerts on and off by clicking the accessibility icon on the top bar and selecting Visual Alerts.
