## Troubleshooting desktop notifications
First, make sure you have enabled
[desktop notifications for PMs](/help/pm-mention-alert-notifications) or for the
[stream](/help/stream-notifications) you are testing with.
Desktop notifications are triggered when a message arrives, and Zulip is not
in focus or the message is offscreen. You must have Zulip open in a browser
tab or in the Zulip desktop app to receive desktop notifications.
**Visual desktop notifications** appear in the corner of your main monitor.
**Audible desktop notifications** make a sound.
The most common issue is that your browser or system settings are blocking
notifications from Zulip.
