Acer short-throw projector S1387n, WXGA 1280x800, 4000 ANSI, 20,000:1, HDMI/VGA/RJ45, 16W speaker, 3.1 kg

The Acer S1387n is a short-throw WXGA projector with a native resolution of 1280×800, designed to deliver bright, detailed images in compact installations. With 4000 ANSI lumens and a contrast ratio of 20,000:1, the unit produces clear visuals in classrooms, meeting rooms and small auditoriums where space is limited and installation flexibility is required. Connectivity includes HDMI, VGA, USB 2.0 and LAN (RJ‑45), and a built‑in 16 W mono speaker supports presentations without external audio equipment. The projector supports ceiling mounting and straightforward setup for recurring use.

Advantages

The short-throw lens allows large images from a short projection distance, reducing shadowing and making the device suitable for smaller rooms. High brightness and a strong contrast ratio provide good visibility even with some ambient light present. Multiple input options (HDMI, VGA, USB and LAN) enable easy integration with laptops, PCs and media players, while the integrated 16 W speaker offers immediate audio for lectures or meetings. At approximately 3.1 kg, the projector is portable enough for shared use between rooms and simple to handle during installation.

• Classrooms and lecture halls with limited projection distance

How to use

Place the projector at the recommended short-throw distance from the projection surface according to the projection size required. Connect a video source using HDMI or VGA, or use USB input for compatible media; for networked presentations connect via LAN (RJ‑45). Power on the projector and select the appropriate input source using the remote control or onboard buttons. Adjust focus and keystone correction as needed to obtain a sharp, geometrically correct image. Use the built‑in speaker for basic audio; for larger rooms or richer sound connect external speakers to a compatible audio output on the source device.

Recommendations

For best image quality, position the projector perpendicular to the screen and minimize ambient light. When ceiling mounting, use a stable mount and ensure adequate ventilation clearance around the projector. Regularly clean the air filter and lens following the manufacturer’s maintenance guidance to maintain brightness and prevent overheating.
