Connect a source via HDMI, USB or AV, or use the built‑in Android 9.0 and Wi‑Fi/Bluetooth to stream content wirelessly or run apps directly on the device. Use the side focus knob for larger adjustments and the rear keystone knob for trapezoidal correction; refine image size with electronic zoom and electronic focus via on‑screen controls or the physical buttons. Adjust volume through the built‑in speaker or connect external speakers via the 3.5 mm output.

Usage recommendations

For best image quality, project onto a neutral, matte white surface in a dimly lit environment and position the projector within the 1.3–5.4 m distance range. Use HDMI for high‑resolution 4K sources and ensure the device has up‑to‑date apps on Android 9.0 before streaming. Allow adequate ventilation during extended use to maintain optimal lamp life.
