Built for meeting rooms and living spaces

The BenQ TK705STI is a short-throw LED projector designed for business presentations and home entertainment. It delivers UHD 4K onscreen resolution with HDR+ and a contrast enhancer for vivid images. Google TV OS is built in, providing direct access to streaming apps without an external device.

Gray cabinet with flexible connectivity

The unit features a 0.8:1 throw ratio that produces a large image from a short distance, simplifying placement on a desk or shelf. Two HDMI 2.1 ports and one USB-C Alt-DP port with power delivery support modern laptops, consoles and media players. Auto keystone, auto focus, auto screen fit and obstacle avoidance handle alignment automatically.

3000 ANSI lumens brightness decides suitability

At 3000 ANSI lumens the projector performs well in rooms with some ambient light, but it is not bright enough for fully sunlit spaces or very large screens. Buyers who need higher output for auditoriums or daylight conference rooms should look elsewhere.

Questions about this item

What does the 0.8:1 throw ratio mean for image size versus placement?

The 0.8:1 throw ratio lets the projector fill a wide screen from a short distance, so a large image fits in a small meeting room.

Which video inputs are available on the TK705STI?

Two HDMI 2.1 ports and one USB-C Alt-DP port with power delivery accept 4K sources.

How does the auto screen fit feature work during setup?

The projector detects the screen edges and obstacles, then adjusts keystone and focus automatically; the step users miss is ensuring the screen is fully visible to the sensor before starting.
