For wireless streaming, a strong and stable Wi-Fi network is paramount. While wireless mirroring can be convenient, it might introduce slight delays or compression, which could be noticeable in fast-paced gaming. For the best movie-watching experience wirelessly, consider using apps that support direct casting to the projector rather than mirroring your entire screen, as this can be more efficient.
What is the difference between screen mirroring and casting?
Screen mirroring, also known as screen sharing, is a process where your phone’s entire display is replicated onto the projector’s screen in real-time. This means everything you see and do on your phone appears on the larger display, including apps, notifications, and navigation. It’s a direct visual transmission of your phone’s interface.
Casting, on the other hand, is a more intelligent form of content transmission. Instead of mirroring your entire screen, you are sending specific content, like a video or music, directly from your phone to the projector. The projector then accesses and plays that content independently, freeing up your phone to be used for other tasks without affecting the playback on the projector.
