With the W4100i from BenQ, you can experience breathtaking home cinema par excellence: with razor-sharp 4K resolution, BenQ HDR PRO™ technology and numerous intelligent image optimisations , every scene is displayed exactly as the director intended. To achieve this, different brightness values are analysed to ensure optimal image quality using a contrast enhancer.
Make your dream of having your own home cinema come true with the BenQ W4100i 4K projector, which offers a reliable entertainment experience with its long-lasting 4-LED light source and the included Android TV dongle.

The highlights of the BenQ W4100i at a glance:

- Thanks to 3,200 ANSI lumens, the projection is also convincing in bright rooms

Optimised HDR display with HDR10, HDR10+ and HDR-PRO™
HDR10 and HDR10+ compatibility
The BenQ W4100i projector easily displays HDR10 and advanced HDR10+ content , ensuring the highest quality projection. HDR10+ enables dynamic colour and contrast adjustments for each individual image, optimising even scenes with constantly changing lighting conditions.
BenQ's HDR-PRO™ technology
BenQ's HDR-PRO™ technology allows image enhancement techniques to be applied precisely to HDR content. This ensures that the high-quality content is displayed perfectly by the projector.

Impressive colour intensity
BenQ also offers a cinematic experience with the W4100i when it comes to colour display: the 100% coverage of the CinematicColor™ DCI-P3 and Rec.709 colour space enables authentic and vivid colours that are precisely defined at the nanometre level. This consistently avoids deviations and mixed colours. What's more, the BenQ W4100i allows you to adjust the colour temperature in eleven stages, so that colours on the screen appear particularly true-to-life and balanced. Compared to many other devices, which only offer two stages, this gives you significantly more control for a perfect white balance at any brightness level. The resulting colour experience does justice to the original visions of the filmmakers in every nuance.

Unlimited entertainment
With the W4100i smart home projector, you can enjoy your favourite content in the best quality, with easy access to popular streaming providers Netflix, Amazon Prime, Disney+ and many other apps. The included Android TV dongle also ensures wireless transmission and easy voice control for a more convenient streaming experience.
Gaming fans also benefit from the W4100i's powerful technology. Automatic detection of ALLM (Auto Low Latency Mode) signals from compatible game consoles, along with an impressive latency of 6.5 ms at 1080P@240Hz and 17.9 ms at 4K@60Hz, ensures smooth gameplay. Coupled with the brilliant 4K resolution, the rich contrast and the large-scale display, the gaming experience is taken to a higher level.

Flexible picture orientation in any room
Whether in the living room, media room or home cinema – the W4100i can be flexibly aligned in a range of different setups. Thanks to the 1.3x zoom and 2D lens shift function (vertically 0–60% and horizontally ±15% max.), the image can be easily aligned, even if the projector is not placed exactly in the centre of the screen. The result is a perfectly aligned image without any loss of resolution, giving you a range of installation and placement options.
