Short-throw projector Vivitek DX335ST — 3,200 ANSI lm, WXGA 1280×800, throw ratio 0.52:1, 16 W speaker, HDMI 2.0

Vivitek DX335ST is a short-throw DLP projector with a native XGA resolution of 1024×768 and projection brightness of 3800 ANSI lumens. It supports screen sizes from 27.3 to 300 inches at a projection distance of 0.75–1.33 m. The projector uses a replaceable lamp light source with a lamp power of 203 W and a rated life of 5000 hours (10000 hours in economy mode). The unit is finished in white and includes a Kensington cable lock slot.

Advantages

The projector delivers high brightness for clear images in well-lit environments and a high contrast ratio (typical 30000:1) for detailed dark and bright scenes. Its short-throw optics (throw ratio 0.52:1) and 1.1× zoom enable large images at short distances. Integrated audio (16 W RMS) and multiple input options including HDMI 2.0, VGA, composite video and analog audio simplify installation and connectivity. Low standby power consumption (0.5 W) and an economy mode extend lamp life and reduce energy use.

Suitable for

• Classrooms and lecture rooms where short-throw projection reduces shadowing
• Small to medium meeting rooms and offices requiring bright imagery
• Environments needing built-in audio for basic sound reinforcement

How to use

Place the projector at the required short-throw distance (0.75–1.33 m) from the screen and adjust zoom and lens position to obtain the desired image size within the supported screen range. Connect source devices using HDMI, VGA, composite or audio cables and, if needed, control the projector via RS-232. Use the remote control or on-device buttons to select input, adjust brightness or switch to economy mode to extend lamp life. Secure the unit with a Kensington lock if additional physical security is required.

Usage recommendations

For stable image quality and longer lamp life, operate the projector in economy mode when maximum brightness is not required and ensure adequate ventilation around the unit. Use short-throw placement to minimise shadows and glare in teaching or presentation environments.
