BenQ Tk705sti LED Short Throw Home Projector 3000 Lumens 4K

Want a massive 4K picture but don't have a big room? The BenQ TK705STi is built for exactly that. Its short-throw lens casts a huge cinematic image from just a short distance away, pairing genuine 4K detail with bright output, ultra-low input lag and Google TV streaming. It's one of the most versatile short-throw projectors for small living rooms and apartments.

Big screen, small room

The standout feature is the 0.8:1 short-throw lens. It can fill a wall with a 100" or larger image from just a couple of metres away, so you get a true big-screen experience in rooms where a normal projector simply wouldn't have the distance. That makes it ideal for apartments, smaller lounges and tight setups where placement has always been the problem.

Bright, vibrant 4K

With 3,000 ANSI lumens and a 600,000:1 contrast ratio, the TK705STi stays bright and watchable even when you can't fully darken the room, which suits the casual, mixed-use living rooms it's designed for. It covers 98% of the Rec.709 colour space with full HDR support (HDR10+, HDR10 and HLG), so films, sport and games all look rich, sharp and natural.

Seriously good for gaming

Gamers get a real treat here. 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 giant screen. Reviewers consistently single out its gaming performance as a highlight, making it a standout choice for big-screen console play in a compact space.

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, quiet and well connected

Thanks to the short throw and built-in 8W speaker, you can be up and watching within minutes of unboxing. Reviewers also note how quietly it runs and how generous the connectivity is, so it slots neatly into a living room without fuss.

In short: if you want the biggest possible 4K picture in a small room, plus fast, responsive gaming and smart streaming, the TK705STi is hard to beat. Backed by 3-year BenQ Australia warranty, fast Australian delivery and local support.
