Mirroring Your Phone Screen Wirelessly
One of the most common ways to stream from your phone to a projector wirelessly is through screen mirroring. This technology essentially duplicates everything displayed on your phone’s screen onto the projector.
Screen Mirroring Technologies
Several built-in technologies facilitate wireless screen mirroring. Understanding these is key to choosing the right method for your device.
AirPlay: For Apple Users
If you’re an iPhone or iPad user, AirPlay is your go-to solution. AirPlay is Apple’s proprietary wireless streaming protocol that allows you to mirror your device’s screen or stream specific content (like videos and music) to AirPlay-compatible devices, including many modern projectors and streaming devices like Apple TV.
To use AirPlay, both your iPhone/iPad and the projector (or streaming device connected to the projector) need to be on the same Wi-Fi network.
Here’s a general process:
1. Ensure your iPhone/iPad and the receiving device are connected to the same Wi-Fi network.
2. On your iPhone/iPad, swipe down from the top-right corner (for newer iPhones) or up from the bottom of the screen (for older iPhones) to open the Control Center.
3. Tap on the “Screen Mirroring” icon.
4. A list of available AirPlay devices will appear. Select your projector or streaming device from the list.
5. If prompted, enter the AirPlay passcode displayed on your projector screen.
