Product information

Description

The Acer QH31s is a compact LCD projector with native 720p (1280×720) resolution and 150 ANSI lumens brightness. Its LED light source provides a long service life, while auto focus and a 1.36 throw ratio (approximately 66" at 2 m) simplify setup for small meeting rooms, classrooms and portable presentations. The projector accepts up to 1920×1080 input and common video modes, and is finished in a neutral grey housing.

Advantages

The LED illumination offers an estimated 30,000-hour lifetime, reducing maintenance and lamp replacement needs. Auto focus speeds up installation and ensures a sharp image without manual adjustments. With its native 16:9 aspect ratio and 720p resolution the unit reproduces widescreen content with correct scaling, while support for higher-resolution inputs provides compatibility with a wide range of source devices. The small size and light weight make the projector easy to carry and reposition.

Suitable for

  • Small meeting rooms and huddle spaces
  • Classroom teaching and training sessions
  • On-the-go presentations for business or education
  • Compact home media viewing where lower ambient light is present

How to use

Place the projector on a stable surface or mount according to the available space, align it with the projection surface and power it on.

Use the built-in speaker for basic audio needs or connect external speakers for fuller sound.

For best image visibility, use the projector in dim or controlled lighting conditions and position it at a distance that yields a screen size within the 35–120" range.
