BenQ TK705i 4K UHD Smart Home Entertainment Projector
The BenQ TK705i is a premium 4K smart home entertainment projector designed for living rooms, movies, sports, streaming and large-screen gaming. Combining true 4K UHD resolution, 3000 ANSI lumens of brightness, BenQ CinematicColor technology, HDR-PRO processing and built-in Google TV, it provides an all-in-one entertainment platform designed for modern home environments.
The DLP projection system delivers a native 3840 × 2160 4K UHD image with approximately 8.3 million pixels. Its 4LED illumination system produces 3000 ANSI lumens and works with a specified 600,000:1 FOFO contrast ratio to deliver strong image depth and visibility in a variety of living-room conditions.
BenQ specifies 98% coverage of the Rec.709 colour gamut, supported by CinematicColor technology for natural and accurate movie reproduction. HDR-PRO processing enhances high-dynamic-range content through advanced tone mapping and contrast optimisation, while support for HDR10, HDR10+ and HLG provides compatibility with a wide range of modern HDR sources.
Auto Cinema Mode intelligently adapts image tone and brightness according to environmental conditions, helping maintain a balanced image as room lighting changes. The projector also incorporates MEMC motion processing for smoother reproduction of fast-moving sports and video content.
Installation is simplified by BenQ’s 8-Way Smart Image Adaptation system. Features include Auto Focus, Auto 2D Keystone, Auto Screen Fit, Auto Obstacle Avoidance, Digital Shift, Auto Cinema Mode and Auto Eye Protection. Automatic keystone correction supports vertical adjustment up to ±30 degrees and horizontal adjustment up to ±20 degrees.
The TK705i incorporates a 1.3x motorized optical zoom together with a 1.0–1.3 throw ratio. The motorized optical system allows image size to be adjusted while maintaining full optical image quality, while additional digital positioning functions provide convenient fine adjustment without physically relocating the projector.
Built-in Google TV provides direct access to compatible streaming applications including officially supported Netflix. Google Cast and compatible iOS mirroring are available for wireless content sharing, while Wi-Fi 6 and Bluetooth 5.2 provide modern wireless connectivity for streaming and compatible external audio devices.
Gaming performance is a major strength of the TK705i. Dual HDMI 2.1 connections support 4K/60Hz signals and Auto Low Latency Mode. BenQ specifies an ultra-low input lag of approximately 5ms at 4K/60Hz, making the projector suitable for responsive large-screen gaming with PlayStation, Xbox, Nintendo Switch, PC and other compatible gaming systems.
Dedicated HDR-FPS and HDR-RPG game modes allow the image to be optimised for different game genres. The projector also supports Sports Mode and MEMC motion processing for smoother action during sporting events and fast-moving video.
The integrated audio system consists of two 8W chamber speakers for a total output of 16W. HDMI eARC supports audio return of up to 7.1 channels to compatible external soundbars, AV receivers and home theatre systems.
The long-life 4LED illumination system is rated for approximately 20,000 hours in Normal Mode and up to 30,000 hours in Eco Mode, eliminating the routine lamp replacement associated with traditional lamp-based projectors.
