Thanks to the 1.6x zoom and flexible, motorised image alignment of up to 50% vertically and 15% horizontally , the projection can be easily adjusted without having to reposition the projector. The projection remains razor-sharp throughout, with no pixel loss or delays, so that every detail is realistically accentuated.
Authentic colours thanks to CinematicColor™
To make the film experience as realistic as possible, the W5850 covers 100% of the Rec. 709 and DCI-P3 colour spaces. In addition, a special colour wheel and rigorous quality testing ensure that every nuance appears exactly as the director intended. This colour intensity is guaranteed ex works thanks to various calibrations that include preset day and night modes. In addition, the white balance can be individually adjusted in eleven stages (comparative models often only allow colour temperature adjustment in two stages) to optimise the mid-tones to your taste.

HDR PRO™ technology and contrast enhancer in perfection
Thanks to BenQ's HDR PRO™ technology, brightness and contrast are optimally balanced with multi-level light control, offering more depth to dark scenes and more detail to bright areas. BenQ HDR projectors come with five different HDR presets that enable optimal brightness control right out of the box. These can then be customised to your personal preferences and circumstances for the best possible display. In combination with HDR10+, the settings adapt to every film scene.
To ensure that contrast is optimally displayed, the W5850 features three special contrast enhancers. The global contrast enhancer improves the overall picture by adjusting dark, medium and light areas, while the local contrast enhancer divides the picture into 1000 segments and analyses the brightness in each of these areas to increase the depth of the picture in a targeted manner. With Dynamic Black technology, the W5850 responds instantly to changes in brightness, dynamically adjusting light output in any changing scene.
Advanced connectivity for 7.1-channel and Dolby Atmos sound
The W5850 offers a wide range of options for connecting external devices such as Blu-ray players, streaming boxes or game consoles, with two HDMI 2.0b (HDCP 2.2), two USB Type A ports, SPDIF and eARC. EARC (only available on HDMI-1) allows 7.1-channel and Dolby Atmos audio signals to be transmitted in full resolution with just a single HDMI cable to the soundbar or amplifier. Thanks to the simple and powerful audio transmission to your preferred speaker system, you can enjoy an impressive sound quality that fills the room with a home cinema feeling.
