Description
The BenQ TK710STi is a 4K UHD (3840x2160) short-throw laser projector delivering 3200 ANSI lumens of brightness, making it well suited to installation spaces where a full-size long-throw projector will not fit. Its 0.69-0.83 throw ratio with 1.2x zoom lets it fill a 100-inch screen from as little as 2 metres, while a laser light source rated at 20,000 hours in both normal and eco modes keeps running costs low compared with lamp-based alternatives.
Built-in Google-licensed Android TV gives the TK710STi native access to streaming apps for content review, training material and presentations without an external media player, and dual HDMI 2.0b inputs with HDCP 2.2 support 4K sources including Blu-ray and set-top boxes. A 600,000:1 dynamic contrast ratio and 95% Rec.709 colour coverage deliver sharp, accurate images, while 3D keystone and corner-fit correction simplify off-axis installation.
Backed by a 3-year manufacturer warranty, the TK710STi suits training rooms, small auditoria and simulation spaces that need bright, high-resolution short-throw projection with minimal maintenance.
Key features
Native 3840x2160 DLP resolution combined with a 20,000-hour laser light source delivers bright, detailed images with 600,000:1 dynamic contrast and consistent output over years of use.
A 0.69-0.83 throw ratio with 1.2x zoom fills a 100-inch screen from around 2 metres, making the TK710STi suitable for compact rooms where a standard-throw projector cannot be positioned.
Integrated Google-licensed Android TV provides direct access to streaming and content apps without a separate media player, plus dual HDMI 2.0b/HDCP2.2 inputs for external 4K sources.
3D keystone correction (vertical, horizontal and rotational, all +/-30 degrees) and a 5W speaker with eARC/Dolby Atmos pass-through make setup and audio integration straightforward.
