Desktop projector OPTOMA X309ST Short throw, DLP, 3700 ANSI lm, XGA 1024x768, 0.617:1 throw, 115% offset, 3 kg, white

The Optoma X309ST Short throw projector delivers bright, vivid presentations for small meeting rooms and classrooms. This DLP projector offers 3700 ANSI lumens of brightness and a native XGA (1024x768) resolution, with a short throw ratio of 0.617:1 that allows large images from close distances. The unit uses a lamp light source with a rated life up to 6000 hours (and up to 10000 hours in economic mode) and supports multiple inputs including HDMI 1.4a and RS-232.

Advantages

High brightness and DLP technology provide clear, colourful images suitable for well-lit rooms. The short throw design enables large projections in confined spaces, reducing shadowing and the need for long cable runs. Long lamp life and energy-saving modes lower operating costs and maintenance frequency. Multiple input options and 3D support increase compatibility with a variety of sources.

Suitable for

• Small meeting rooms
• Classrooms and lecture spaces
• Training sessions and workshops
• Places requiring large images from short distances

How to use

Place the Optoma X309ST at the recommended distance according to the throw ratio to achieve the desired image size; for short-throw setups this typically means positioning the projector close to the screen or wall. Connect a video source using HDMI or other available inputs, power on the unit and select the appropriate input. Adjust focus and keystone as needed for a sharp, rectangular image. Choose the economic lamp mode to extend lamp life when maximum brightness is not required.

Recommendations

For best results in small meeting rooms and classrooms, install the projector so the lens is as close as practical to the screen to minimize shadows and deliver a large image. Use economic mode during routine presentations to conserve lamp life and switch to full brightness only when ambient light requires it. Ensure adequate ventilation and follow the manufacturer's lamp replacement guidelines.
