2. iPhone: Wireless Connection (AirPlay)
What You Need
- Option 1: Smart projector with built-in AirPlay (Anker Nebula, XGIMI, Epson with wireless)
- Option 2: Apple TV connected to projector's HDMI port
- Option 3: AirPlay-compatible streaming device (some Roku models)
- Requirement: iPhone and projector/device must be on same WiFi network
Step-by-Step Instructions (AirPlay)
- Step 1: Ensure same WiFi network
iPhone Settings → WiFi → Verify network name matches projector's network.
- Step 2: Open Control Center
Swipe down from top-right corner (iPhone X and newer) or swipe up from bottom (older iPhones).
- Step 3: Tap Screen Mirroring
Look for icon with two overlapping rectangles. Tap it.
- Step 4: Select your projector
Choose projector name from list (e.g., "Living Room Projector", "Apple TV").
- Step 5: Enter code if prompted
Some projectors show 4-digit code for first-time pairing. Enter on iPhone.
- Step 6: iPhone screen mirrors to projector
Entire iPhone display now visible on projector. Rotate phone for landscape viewing.
⚠️ Important Notes:
- AirPlay requires strong WiFi signal. Weak signal causes lag and disconnections.
- Some streaming apps (Netflix, Disney+) may block AirPlay mirroring due to DRM. Use wired connection if this occurs.
- Battery drains faster during wireless mirroring. Keep iPhone plugged into charger for long sessions.

3. Android: Wired Connection (USB-C to HDMI)
⚠️ CRITICAL: Check Phone Compatibility First
Not all USB-C ports support video output. Your phone must support DisplayPort Alt Mode.
Phones that support video output:
- Samsung Galaxy S8 and newer (S-series, Note series, Z Fold/Flip)
- Google Pixel 2 and newer
- OnePlus 5 and newer
- LG V20, V30, V40, V50
- Motorola Edge, Edge+ (2020 and newer)
- Most flagship Android phones from 2019+
Budget phones often don't support video output. Check manufacturer specs for "DisplayPort Alt Mode", "video output", or "HDMI support" before buying cable.
Required Equipment
- USB-C to HDMI Cable or Adapter
Direct cable ($10-25) or USB-C hub with HDMI ($25-50)
Must specify "supports video" or "DisplayPort Alt Mode"
- For Older Android (Micro USB)
MHL adapter required (rare - most modern phones use USB-C)
Check if phone supports MHL before purchasing
Step-by-Step Instructions
- Step 1: Connect USB-C cable to phone
Plug USB-C end into phone's charging port.
- Step 2: Connect HDMI to projector
Connect HDMI end to projector's HDMI port.
- Step 3: Change projector input
Use projector remote to select correct HDMI input source.
- Step 4: Phone detects connection automatically
"Once connected, simply change the source on your projector to the relevant HDMI port" and phone screen appears.
- Step 5: (Optional) Adjust display settings
Some Android phones show notification for "HDMI output" with resolution options. Default usually works fine.
✅ Pro Tip:
Many USB-C hubs include HDMI + charging port. This lets you charge phone while connected to projector, preventing battery drain during long movie sessions.

4. Android: Wireless Connection (Miracast)
What is Miracast?
Miracast is Android's built-in wireless display technology (similar to AirPlay for iPhone).
Requirements:
- Android 4.2 or newer (most devices since 2013)
- Projector with Miracast support OR Miracast adapter
- Both devices on same WiFi network (WiFi Direct also works)
Step-by-Step Instructions
- Step 1: Open Settings on Android
Settings app → Connected Devices → Connection Preferences
- Step 2: Find Cast or Screen Mirroring
Look for "Cast", "Smart View", "Wireless Display", or "Screen Mirroring" (name varies by manufacturer).
- Samsung: "Smart View"
- LG: "Screen Share"
- Motorola/Google: "Cast"
- OnePlus: "Cast"
- Step 3: Enable wireless display
Tap the option. Phone searches for available devices.
- Step 4: Select your projector
Tap projector name when it appears in list.
- Step 5: Confirm connection on projector
Some projectors require confirmation. Accept pairing request.
- Step 6: Phone screen mirrors to projector
Everything on phone now visible on projector.
⚠️ Troubleshooting Miracast:
- Projector not appearing: Ensure projector's wireless display mode is enabled. Check projector menu for "Miracast", "WiFi Display", or "Screen Share" option.
- Connection drops: Move closer to projector. Wireless display requires strong signal.
- Lag/stuttering: Close background apps. Wireless mirroring is resource-intensive.
- If projector lacks Miracast: Buy Miracast adapter ($20-40) and plug into HDMI port.

6. Troubleshooting Common Issues
Problem: No Signal / Black Screen
Most Common Cause: Wrong HDMI input selected on projector
Solutions:
- Press "Source" or "Input" button on projector remote
- Cycle through all HDMI inputs (HDMI 1, HDMI 2, etc.)
- Try different HDMI port on projector
- Disconnect and reconnect cable firmly
- Try cable with different device to verify cable works
Problem: Video Works But No Audio
Wired Connection:
- Check if projector has built-in speakers (many don't)
- Connect external speakers to projector's audio out port
- Or use Bluetooth speaker paired to phone
Wireless Connection:
- Audio usually stays on phone by default
- iPhone: Control Center → tap audio output → select projector
- Android: Settings → Connections → Bluetooth → select projector for audio
Problem: USB-C to HDMI Not Working (Android)
Causes & Solutions:
- Phone doesn't support video output
Check phone specs for "DisplayPort Alt Mode" support. Budget phones often lack this feature.
- Wrong cable type
Not all USB-C cables support video. Cable must explicitly state "supports video" or "DisplayPort".
- Phone charging only
Notification may ask "USB for": select "File Transfer" or "HDMI" option if prompted.
Problem: Streaming App Shows Black Screen (Netflix, Disney+)
Cause: HDCP (copy protection) blocking screen mirroring
Solutions:
- Best fix: Use Chromecast, Roku, or Fire TV instead of screen mirroring. These devices support HDCP.
- Wired connection: Switch to HDMI cable connection (usually works)
- Alternative: Download content for offline viewing before connecting
Problem: Wireless Connection Keeps Dropping
Solutions:
- Move phone closer to projector (within 15 feet ideal)
- Check WiFi signal strength - weak signal causes disconnections
- Close unnecessary apps on phone to free up resources
- Restart both phone and projector
- Update phone and projector firmware to latest versions
- If using WiFi Direct: ensure no other devices competing for connection
Problem: Image Fills Screen But Has Black Bars
Cause: Aspect ratio mismatch between phone and projector
Solutions:
- Rotate phone to landscape for full-screen viewing
- Check projector settings for "Aspect Ratio" or "Zoom" options
- Some apps force portrait mode - this is normal
- Use projector's keystone correction if image appears distorted
🔧 Quick Fixes for Most Issues:
- 1. Restart phone and projector
- 2. Disconnect and reconnect cable firmly
- 3. Try different HDMI port on projector
- 4. Update phone and projector software
- 5. If wireless: forget network and reconnect
