4.2 App Management & Side-loading

Once installed, you gain access to your favorite APK apps and games.

4.3 DRM Information & Streaming Limitations
The projector is not Google Certified, which means it may not have the necessary digital rights management (DRM) to run subscription services like Netflix and Amazon Prime Video in HD or 4K quality. The device only has Google Widevine Level 3 with no HDCP protection. This may limit streaming quality on certain platforms.

The C55 projector supports various media formats and offers built-in decoders for enhanced audio-visual experience.
5.1 Video Playback
The projector has built-in decoders that allow you to play 4K videos and scale them down to 1080p. For YouTube videos, you can install the Android TV version or the smart YouTube TV version. Both apps limit the resolution to 720p with no HDR.
5.2 Audio Playback
The projector includes built-in decoders for Dolby and DTS audio playback. Its internal speaker provides decent sound quality, but for a more immersive experience, you can pair Bluetooth headphones, Bluetooth speakers, or audio receivers.

8. Troubleshooting
Here are some common issues and their potential solutions:

- Image is distorted (not rectangular): Adjust keystone correction manually or enable automatic trapezoid correction in settings.
- No sound from streaming apps (e.g., Netflix): This projector may not support certain DRM-protected content in high quality due to Widevine L3. Consider connecting an external streaming device (like a Fire Stick or Roku) to an HDMI port for full compatibility.
- Cannot connect to Wi-Fi/Bluetooth: Ensure the Wi-Fi/Bluetooth is enabled in settings. Check your network connection. Try restarting the projector.
- Projector freezes or is unresponsive: Perform a factory reset via the System Update settings.
- Overheating: Ensure the dust filter is clean and the cooling fan vents are not obstructed. Allow the projector to rest every few hours during extended use.
