Hyper-Realistic HDR-PRO™
BenQ exclusive HDR-PRO technology enhances the 4K HDR viewing experience with greater contrast range and better detail. TK850 is supercharged with HDR10 & HLG(Hybrid Log-Gamma) support for unparalleled enjoyment.
* HLG is a high dynamic range (HDR) standard that was jointly developed by the BBC and NHK, supported by video services such as the BBC iPlayer, DirecTV, Freeview Play, and YouTube.
See in the Dark
Some HDR projectors can lose details and display incorrect greyscales. BenQ Enhanced Cinema-Optimized Tone Mapping with Dynamic Iris and Dynamic Black technology* increases contrast ratio, preserving dark details in total clarity.
*Dynamic iris controls the amount of light through the optical system for ideal contrast. Dynamic Black™ analyzes a scene’s brightness levels to optimize light output and contrast. By bringing out subtle details in shadows and preventing bright scenes from washout.
HDR Brightness
Keep ideal high contrast while projecting different image sizes and various screen gains most commonly used in home theater. This ensures greater contrast range and superior image quality when HDR mode is activated.
Premium 4K Lens Architecture
TK850’s 4K optical system uses the highest-grade glass for superior realistic image quality. The precision, 10-element, 8-group lens array allows greater light penetration for long-lasting 4K intensity.
Accurate Images
DMD DLP technology overcomes known alignment issues of LCD multiple panels. TK850 ensures image integrity and razor-sharp images devoid of artifacts such as blur, shadowing, and interference patterns.
Flawless Optics for Superb Image Quality
The BenQ 4K optical system uses only the highest grade glass for superior light penetration and realistic image quality. The proprietary low-dispersion lens coatings minimize chromatic aberration, so you can enjoy your favorite 4K UHD content in brilliant clarity.
Sports Mode
Enjoy enhanced video quality with realistic skin tones, balanced outdoor blues and greens, and warm woodgrains for indoor sports action. Sports Mode also boosts the thrill of victory, accentuating the announcer’s commentary and the roar of the crowd.
Motion Enhancer eliminates laggy images, jittery playback, and blurry shadows
Motion Enhancer
Eliminate laggy images, jittery playback, and blurry shadows. Interpolated frames are generated and displayed between individual frames. TK850 inserts 36 interpolated frames per minute for seamless, vivid 60-frames-per-second videos.
Indulge in Immersive Sound

Easy Upgrade
TK850 offers +10% vertical lens shift, making it adaptable to any room. It can use the same ceiling mount and screen as many BenQ1080 projectors with similar throw ratios, 1.13 - 1.47 (100" @ 8.2 feet), so it’s easy to upgrade to the 4K TK850 without screen size and throw distance calculations.*
Perfect Alignment
Keystone correction lets you project perfectly aligned images from many spots in a room. The vertical keystone function adjusts the image for a professionally squared image, countering the trapezoid effect when the projector must be placed off-center.

TK850 maintains image integrity with zoom. By maintaining consistent zoom ratio, images retain visually perfect focus from corner to corner.
