Product information

Description

The Optoma W309ST is a short-throw DLP projector designed for business and education environments. It delivers large images from a short distance, provides flexible connectivity including USB power and HDMI, and is intended for use where ambient light is present. The projector uses a lamp light source and offers a WXGA native resolution with a 16:10 aspect ratio suitable for modern notebooks and presentations.

Advantages

The W309ST produces bright images (3800 ANSI lumens) and high contrast for clear text and vivid colors. Its short-throw optics create a 100-inch image from approximately 1.1 meters, reducing shadows and allowing placement close to the screen. An integrated 10 W speaker and USB power output (5 V / 1.5 A) simplify setup by powering streaming dongles and charging small devices. ECO+ mode extends lamp life and reduces power consumption, while low operating noise (around 28 dB in ECO mode) supports undisturbed presentations.

Suitable for

  • Classroom teaching and lecture halls
  • Meeting rooms and corporate presentations
  • Small to medium-sized training spaces
  • Spaces with ambient light where short throw projection is needed

Key specifications

  • Projection technology: DLP
  • Native resolution: WXGA (1280 × 800)
  • Brightness: 3800 ANSI lumens
  • Native aspect ratio: 16:10
  • Throw ratio / capability: short throw — 100" image from ~1.1 m
  • Light source: lamp with extended-life ECO+ mode
  • Integrated audio: 10 W speaker
  • Built-in USB power output: 5 V / 1.5 A
  • Typical operating noise: ~28 dB (ECO mode)
  • Weight: 2.9 kg
  • Color: white

How to use

Place the projector close to the screen or wall to achieve a large image with minimal shadows; for a 100-inch diagonal image position the lens at about 1.1 metres from the projection surface. Connect video sources via HDMI or other supported inputs and, if required, power a streaming dongle or charge a mobile device using the projector's USB power output. Adjust focus and keystone if available for a sharp rectangular image. Use ECO+ mode to reduce brightness and extend lamp life when full brightness is not necessary.

Usage recommendations

For presentations in rooms with ambient light, keep the projector close to the screen to avoid glare and shadows. Use the integrated speaker for basic audio needs and the USB power port to run compatible streaming dongles; consider external audio for larger rooms. Activate ECO+ mode when possible to lower power consumption and maximize lamp life.
