4K HDR High Brightness Streaming Enjoyment
BenQ, the number 1 DLP 4K projector brand worldwide, designed the TK850i smart home projector with HDR-PROTM technology, especially for well-lit rooms.
BenQ’s exclusive HDR-PRO projection technology enhances the 4K HDR contrast range ensuring improved details. Supercharged by HDR10 and HLG (Hybrid Log-Gamma) support, you’ll enjoy an unrivalled visual experience. From live sports to 4K Blu-ray discs, viewing will never be the same again.
(* HLG is a high dynamic range (HDR) standard developed by the BBC and NHK. It is supported by video services such as the BBC iPlayer, DirecTV, Freeview Play, and YouTube.)
Enhanced Tone Mapping
Cinema-Optimised Tone Mapping with Dynamic Iris and Dynamic Black addresses common HDR projector detail and greyscale issues with improved contrast and detailed display.
(* The Dynamic Iris controls the amount of light through the optical system for ideal contrast. Dynamic Black analyses a scene’s brightness levels to optimise light output and contrast. This brings out subtle details in shadows and prevents washout in bright scenes.)
HDR Optimised Adaptive Brightness
HDR brightness optimisation expands the contrast range for superior image quality when HDR is activated. This means more realistic video for your enjoyment.
Every 4K Pixel Counts
Breath-taking true 4K UHD 3840x2160 resolution with 8.3 million distinct pixels reduces blur for stunning clarity and crisply defined details for every moment of every exciting sports game or streaming content.

Tailor-Made for Sports Events
The TK850i’s dedicated Sports Mode enhances video quality with realistic skin tones, naturally balanced blues and greens highlighting playing fields, and warm woodgrains for indoor sports action. Sports Mode also boosts intensity by accentuating the announcer’s commentary and the roar of the crowd.
Sports Motion Enhancer
The Motion Enhancer (MEMC) eliminates jittery playback and blurry shadows by inserting 36 interpolated frames between sequences for seamless, crisp 60 frames-per-second video.
A powerful 10-watt chambered speaker enhances the sound quality for elevated enjoyment. The TK850i is perfect for viewing sports, playing video games, watching movies, or streaming.

The TK850i offers a 10% vertical lens shift to fit perfectly into any room with varied projection distances and heights. Additionally the 1.3X big zoom offers a wide range of throw distances for installation flexibility with diverse mounting and placement options. It’s easy to upgrade from an existing 1080p BenQ projector to the TK850i 4K projector using the same ceiling mount without the need to recalculate screen size and throw distance.
