Description
If you want one 4K projector that does it all, movies, sport, streaming and serious gaming, the BenQ TK705i is built for exactly that. It pairs a bright, punchy 4K picture with ultra-low input lag and smart Google TV, making it one of the most versatile home entertainment projectors in its class.
Bright, vibrant 4K for any room
With 3,000 ANSI lumens and a 600,000:1 contrast ratio, the TK705i stays bright and watchable even when you can't fully black out the room, which makes it a genuine all-rounder for movie nights, weekend sport and everyday streaming. It covers 98% of the Rec.709 colour space with full HDR support (HDR10+, HDR10 and HLG), so colours look rich and natural and HDR content has real punch.
Built for gaming
This is where the TK705i really shines. Input lag drops to just 5ms at 4K 60Hz, which is exceptionally fast for a 4K projector, so PS5, Xbox and PC gaming feel sharp and responsive on a big screen. Reviewers testing fast titles like racing games consistently highlight how smooth and lag-free it feels, making it a standout choice for gamers who want cinema-scale play without the input delay.
Long-life LED light source
The 4LED light engine is rated for 20,000 to 30,000 hours, so it should comfortably outlast a traditional lamp projector without you ever buying a replacement bulb. It reaches full brightness almost instantly, with no warm-up wait and no colour drift over time.
Smart streaming built in
Google TV is built right in, so Netflix, Prime Video, Disney+, YouTube and thousands of other apps run directly on the projector with Chromecast and voice search included. There's no need for a separate streaming box.
Easy setup and great sound
A 1.0 to 1.3 throw ratio with zoom makes it simple to position in a wide range of rooms, and BenQ's automatic picture and screen-fit adjustments take the fuss out of setup. The built-in 8W speaker delivers genuinely good sound for an all-in-one projector, so you can be watching properly within minutes of unboxing.
In short: bright, fast and smart, the TK705i is an outstanding choice if you want a single projector that handles movies and big-screen gaming equally well. Backed by 3 Years BenQ Australia warranty, fast Australian delivery and local support.
