Picture and sound quality
Based on DLP technology with a 0.65-inch DMD chip (DC3), the LS901-4K delivers precise image sharpness and a dynamic contrast ratio of 3,000,000:1. With 5,500 ANSI lumens, the system is suitable for rooms with incoming daylight. SuperColor technology ensures vivid colour reproduction of up to 1.07 billion colours.
The integrated audio system consists of two 15-watt speakers with a total output of 30 watts, enough to fill small to medium-sized conference rooms without an external sound system.
- 2x HDMI 2.0 (HDCP 2.2)
- 1x audio output (3.5 mm jack)
- 1x USB Type A (5V/1.5A power supply & service)
- 1x RS232 control
- 1x RJ45 (LAN Control)
Mounting and installation
The projector supports flexible installation options, including inverted ceiling mounting, 360° projection and portrait operation (portrait mode). Manual keystone correction of +/- 30° (horizontal and vertical) and 4-corner adjustment make geometric alignment on the projection surface easy.
In the box: LS901-4K, power cable, remote control, lens cap and quick start guide.
For theft protection, the unit has a Kensington lock (security slot) and software-level password protection.
Note on wall distance planning: add 28.0 cm plus approx. 7–12 cm for plugs/cable exit.
According to the manufacturer, this projector supports image sizes from 30 inches (76 cm) to 300 inches (762 cm).
The throw distance specified by the manufacturer is a minimum of 0.80 m and a maximum of 13.55 m.
| Image size (diagonal) | Image width (approx.) | Throw distance |
|---|---|---|
| 80 inches | 177 cm | min. 2.12 m – max. 3.61 m |
| 100 inches | 221 cm | min. 2.65 m – max. 4.51 m |
| 120 inches | 265 cm | min. 3.18 m – max. 5.41 m |
Running and follow-up costs

No regular lamp replacement required – low-maintenance in continuous operation.
