Difference Between Cast Screen and Screen Mirroring


Key Differences

Cast Screen and Screen Mirroring are both terms related to displaying content from one device onto another. However, their functionalities are distinct. Cast Screen is about sending specific content, like a movie or presentation, to a display. Screen Mirroring, on the other hand, replicates the entire screen of one device onto another.
With Cast Screen, a user can stream videos, music, or other media from a source device to a television or monitor. This doesn't necessarily display everything that's happening on the source device. For instance, notifications and other activities remain private. Screen Mirroring, on the contrary, acts like a mirror, reflecting every activity on the primary device, be it notifications, messages, or any other operations.
Another notable distinction is the usability. While Cast Screen may require specific apps or platforms to cast content, like Google Cast or Apple AirPlay, Screen Mirroring doesn't usually need such specific applications. Instead, it works on a broader device-to-device level.
In terms of user control, Cast Screen might not allow interactions on the secondary display, meaning the control remains with the source device. With Screen Mirroring, the mirrored screen often can be interacted with if the secondary device is touch-enabled.
Lastly, Cast Screen usually focuses on delivering high-quality content without consuming too much power. This means the primary device can be in sleep mode while casting. In the case of Screen Mirroring, the primary device must remain active, as it's constantly transmitting its entire display.
