　　Outdoor Movie Night Selection & Usage Tips

　　1. Brightness Matching: Prioritize models with CVIA lumens ≥ 350 for fully dark environments (night campsites); choose 1,000-3,000 CVIA lumens if using near light sources. Avoid "dynamic brightness" and focus on stable continuous output for consistent viewing.

　　2. Portability & Durability: Select models weighing ≤ 3kg for easy carrying. Full-closed optical machines are preferred to prevent dust from damaging internal components. Opt for units with good heat dissipation to adapt to outdoor temperature changes.

　　3. Connectivity & Audio: WiFi 6 ensures stable wireless casting in open spaces; pre-download movies if WiFi is unavailable. Pair with portable Bluetooth speakers for better sound—outdoor open areas require enhanced audio to avoid sound dispersion.

　　4. Setup Optimization: Prepare a portable projection screen or use a white tent wall/bed sheet for better image effect. Bring a small tripod to fix the projector, and use the keystone correction function to adjust the screen for outdoor uneven ground.
