Sharing photos, videos or a game from your phone on a big projected screen is one of the best things about a smart projector. There are three main ways to do it. Which one is best depends on your phone and what you want to watch.
Option 1: Use the projector's built-in apps (best for streaming)
If you just want to watch Netflix, Prime Video or YouTube, you often don't need your phone at all. The Cavon HY300 PRO+ runs Android 14 with built-in apps, so you can sign in on the projector itself and stream over Wi-Fi. This usually gives the smoothest picture and frees up your phone.
Why this matters: many paid streaming apps block screen mirroring for copyright reasons, so you may see sound but a black picture when mirroring. Opening the app directly on the projector avoids this.
Option 2: Wireless screen mirroring
Screen mirroring shows exactly what's on your phone — photos, browser, presentations or apps — on the projected screen.
Before you start
- Connect the projector and your phone to the same Wi-Fi network.
- The HY300 PRO+ supports dual-band Wi-Fi 6. If your router offers both 2.4 GHz and 5 GHz, 5 GHz is usually smoother for mirroring when you're close to the router.
Android phones
- On the projector, open the screen mirroring / casting option from the home screen.
- On your phone, swipe down to Quick Settings and tap Cast, Smart View or Screen mirroring (the name depends on the phone brand).
- Choose the projector from the list and accept the connection if asked.
iPhone and iPad
- On the projector, open the screen mirroring option and select the iOS mode if there's a choice.
- On your iPhone, open Control Centre and tap Screen Mirroring.
- Choose the projector from the list.
Follow any instructions shown on the projector screen, as the steps can vary slightly with software updates.
Option 3: A cable with an HDMI adapter
A wired connection is reliable and has no Wi-Fi delay, which is useful for games or presentations. The HY300 PRO+ has an HDMI input.
- iPhone with Lightning: use Apple's Lightning Digital AV Adapter plus an HDMI cable.
- iPhone 15 or later, and many Android phones with USB-C: use a USB-C to HDMI adapter. On Android, check that your phone supports video output over USB-C — not every model does.
Plug in the cable, then select the HDMI input on the projector.
Troubleshooting
- Projector doesn't appear on your phone: check both are on the same Wi-Fi network, then restart the mirroring screen on the projector.
- Sound but no picture in a streaming app: the app is blocking mirroring — use the built-in app on the projector instead.
- Picture stutters: move closer to the router, switch to 5 GHz, or use an HDMI cable.
- Sound is quiet: turn up the volume on both the phone and the projector, or connect a Bluetooth speaker to the projector.
