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.
