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 4K 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-Optimized 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 optimize light output and contrast. This brings out subtle details in shadows and prevents washout in bright scenes.
