If you’re using a specific app for screen mirroring, try uninstalling and reinstalling it, or check the app’s compatibility with your phone model and projector.
What is the difference between screen mirroring and casting to a GPX projector?
Screen mirroring, often referred to as “mirroring” or “display mirroring,” duplicates everything on your phone’s screen and displays it on the projector’s screen in real-time. This is a direct transmission of your phone’s entire interface, allowing you to interact with your phone as you normally would, but projected larger. Technologies like Miracast and AirPlay primarily facilitate screen mirroring.
Casting, on the other hand, allows you to send specific content, like a video or music file, from a compatible app on your phone to the projector. The projector then directly streams that content from the internet or your phone’s storage, freeing up your phone for other tasks without interrupting playback. This is often achieved through protocols like Chromecast or AirPlay’s casting function.
Will my phone’s battery drain quickly when connected to a GPX projector?
Yes, connecting your phone to a GPX projector, especially for extended periods and with the screen mirroring functionality active, can significantly increase battery consumption. Displaying video and maintaining the connection, whether wired or wireless, requires considerable processing power and screen activity, all of which draw heavily on your phone’s battery.
To mitigate rapid battery drain, it’s recommended to connect your phone to a power source while it’s projecting, if possible. Lowering your phone’s screen brightness, closing unnecessary background apps, and disabling features like Wi-Fi or Bluetooth when not actively in use can also help conserve battery life.
