How it works
Screen mirroring reproduces a device’s screen on another display. It is different from sending a media stream that the receiver plays independently. Compatibility, network conditions and application restrictions determine what can be shown and how responsive it feels.
A practical example
A presentation may mirror well while a protected video remains unavailable. Notifications can also appear on the shared screen. Before a meeting, test the actual application and adjust notification privacy rather than assuming every visible item stays private.
What to check
Confirm sender and receiver support, the selected target and any required network access. Test sound, aspect ratio and delay. Stop sharing after the task and check who can connect to the receiver.
Limits and safe next steps
Mirroring latency may make fast gaming uncomfortable even when video playback looks fine. Avoid disabling network isolation broadly as a first fix. Follow platform guidance and use a supported wired option where suitable.
