BenQ TK705i 4K UHD DLP Home Entertainment Projector, 3000 ANSI lm, LED, 1.0–1.3 throw, 16:9

BenQ TK705i is a 4K UHD DLP home entertainment projector designed for movies, sports and gaming. It delivers up to 3000 ANSI lumens of brightness with an LED light source and native 3840×2160 resolution at a 16:9 aspect ratio. With a 1.0–1.3 throw ratio, 1.3× zoom and multiple colour modes, the projector supports flexible placement and sharp, colour-accurate images for living-room viewing.

Advantages

High brightness and BenQ CinematicColor with HDR-PRO provide vivid, high-contrast 4K visuals even in well-lit rooms. The TK705i offers calibrated colour fidelity for natural tones, advanced HDR tone mapping to reveal detail in bright and dark scenes, and ultra-low input lag (5 ms at 4K/60Hz) for responsive gaming. Built-in Google TV, Bluetooth 5.2 and Wi‑Fi support streaming and connectivity, while USB-C (up to 30W) enables play-and-charge for compatible devices.

Suitable for

• Home cinema and movie nights in medium to large rooms
• Console and PC gaming with low-latency input
• Sports viewing and live broadcasts where brightness is important
• Wireless streaming via built-in Google TV and network apps

When it may not be suitable

The TK705i is optimized for home entertainment and gaming rather than professional cinema calibration or high-end studio colour grading. It may not be the best choice for environments that require specialised pro-level colour standards or where absolute blackout conditions are required for projection.

How to use

Place the projector on a shelf, tripod or mount it on the ceiling using the provided mounting holes, then connect your source via HDMI, USB-C or stream directly with Google TV. Use the Smart Image Adaptation and 8-way automatic adjustment to quickly align and sharpen the picture. For gaming, enable ALLM and connect a console via HDMI 2.1 to reduce input lag. If using USB-C devices, you can charge compatible devices while playing.

What to consider before purchase

• Room lighting: while 3000 ANSI lumens supports bright rooms, optimal contrast benefits from dimmed lighting
• Placement and throw distance: ensure your room supports a 1.0–1.3 throw ratio for desired screen size up to 150"
• Sound setup: built-in 16 W speaker is suitable for casual use; consider an external soundbar for fuller audio
• Device compatibility: verify USB-C charging and HDMI 2.1 features with your console or source device
• Software updates: update projector OS via OTA to the required version for full app and assistant functionality

Usage recommendations

For best picture quality, update the projector to the latest OTA firmware, place it at a suitable throw distance for your desired screen size, use the Smart Image Adaptation to auto-align the image, and enable the appropriate HDR Game Mode or cinema colour mode depending on content. When gaming, connect via HDMI 2.1 and enable ALLM for minimal input lag.
