High-contrast 4K picture
The picture is based on a DLP chip that renders details in 4K UHD resolution with a 16:9 aspect ratio. The brightness of 3500 ANSI lumens provides a clear picture even in rooms with ambient light. The projector works with a high dynamic contrast ratio of 3000000:1, which contributes to deep blacks and clarity in dark scenes. The image size can be adjusted from 60" to 300".
Laser light source
The third-generation laser-phosphor light source has a lifespan of 20000 hours in normal mode. In the energy-saving ECO mode, the lifespan reaches up to 30000 hours. The cooling fan noise is 32dB in normal mode and drops to 26dB in ECO mode. The power consumption in normal operation is 143W, while in standby mode the consumption is less than 0.5W.
Flexible installation
Thanks to its short throw distance, the projector can be placed closer to the projection surface. It creates a 100" image from a distance of approximately 2.5 metres. Precise image alignment is facilitated by keystone and four-corner correction. A 1.3× optical zoom is also available. The projector can be installed on the ceiling or used as a freestanding unit.
