Projection Technology and Light Source
This model uses a laser phosphor light source, which offers several advantages over traditional lamp-based projectors.
The laser delivers consistent brightness over a longer lifespan (up to 20,000 hours), reduces maintenance costs, and provides instant on/off capability without warm-up or cool-down time.

The projector supports WXGA resolution (1280×800), which is adequate for presentations, videos, and educational content.
Colors are vibrant and images are sharp, thanks to the DLP technology and laser light source combination. Contrast ratios are decent, providing good differentiation between light and dark areas.
Lens and Throw Ratio
Equipped with a fixed lens, the projector has a moderate throw ratio suitable for medium to large rooms.
The image size can be adjusted from approximately 30 to 300 inches diagonally, providing flexibility in various environments. Keystone correction and other image adjustment features help in achieving the best possible picture alignment.
Connectivity Options
The LSD400WE offers a good range of connectivity ports, including HDMI, VGA, USB, and audio inputs.
This versatility allows easy connection to laptops, document cameras, Blu-ray players, and other multimedia devices. USB ports can also be used for firmware updates or powering external devices.
