BenQ TK700STi — 4K HDR Short-Throw Gaming Projector
A 3840 × 2160 4K UHD DLP projector rated at 3000 ANSI lumens with a 0.9–1.08 short-throw lens and 1.2x zoom, so a big image fits a living room. BenQ lists input lag as low as 4.2 ms at 1080p 240Hz (8.3 ms at 120Hz, 16.7 ms at 4K 60Hz), with HDR / HLG, 3D, 96% Rec.709 and 1.07 billion colours. Two HDMI 2.0b inputs take a PS5, Xbox Series X, Switch or PC, a 5W chambered speaker is built in, and the bundled QS01 Android TV dongle adds streaming apps.
Big-Screen Console and PC Gaming
Game mode drops input lag to 4.2 ms at 1080p 240Hz or 8.3 ms at 120Hz, and 4K 60Hz HDR runs at 16.7 ms — on a 100-inch image from about 2–2.4 m away.
Home Cinema and Streaming
True 4K with HDR and HLG, 96% Rec.709 colour and 1.07 billion colours, plus Android TV apps through the bundled QS01 dongle and audio out or audio return for a soundbar.
Hardware Craftsmanship & Visual Innovations
Dual HDMI 2.0b with Audio Return on HDMI-2
The rear panel shows two HDMI 2.0b inputs with HDCP 2.2 — HDMI-2 adds audio return for a soundbar — plus a 3.5 mm audio out and a USB-A port with 1.5A power for the Android TV dongle. RS232 control is also listed.
±30° Vertical and Horizontal Keystone
2D keystone squares up the image when the projector cannot sit dead-centre, correcting up to ±30 degrees vertically and horizontally, with automatic vertical correction.
Large Images from a Short Distance
The graphic shows image size growing with distance: the 0.9–1.08 throw ratio and 1.2x zoom put a 100-inch picture (2.2 m wide) about 2.0–2.4 m from the screen, so it suits rooms where a long-throw projector would not fit.
Android TV Dongle and Unity Remote Included
The box contents: power cord, the unity remote that controls both projector and Android TV, and the QS01 Android TV dongle that plugs into the projector for streaming apps.
