In the world of home entertainment, projectors have come a long way from their bulky, movie-only beginnings. Now, they are sleek, multi-purpose devices that can be used for gaming, streaming, and watching movies. The BenQ TK705STi is a DLP LED-powered 4K UHD HDR short throw smart gaming projector that promises to turn small living spaces into theaters. This projector came out in late 2025 and has the best picture quality, easy setup, and smart features, making it a great choice for modern homes. The TK705STi works great for both hardcore gamers playing fast-paced FPS games and families who want to watch a lot of Netflix at once. It doesn’t sacrifice convenience for performance.
New and advanced visual technology
The TK705STi’s advanced DLP (Digital Light Processing) engine and LED light source work together to show true 4K UHD resolution at 3840 x 2160 pixels. With an amazing 3,000 ANSI lumens of brightness, this pixel-shifting technology makes sure that images up to 150 inches wide are clear and detailed, even in bright rooms. BenQ’s own CinematicColor technology covers 98% of the Rec.709 color gamut, giving colors that look real and tones that match what the director wanted. HDR-PRO support, which includes HDR10+, improves dynamic range for deeper blacks, brighter highlights, and more subtle contrast. It has a full on/full off (FOFO) ratio of 600,000:1, which makes shadows stand out and explosions shine. The LED source not only avoids problems with laser speckle, but it also lasts for 20,000 hours, so you can watch it for years without having to worry about it fading or having to clean it like you would with regular lamps.
Short Throw Design for Setups That Save Space
The TK705STi’s short throw lens is one of its most cutting-edge features. It has a throw ratio of 0.8:1, which means it can project a huge 100-inch image from just 5 feet away or a full 150 inches from less than 8 feet away. This makes it perfect for small rooms, apartments, or any setup where space is limited because it doesn’t need long cable runs or ceiling mounts. BenQ’s 8-Way Smart Image Adaptation makes setup easy. It automatically fixes vertical and horizontal keystones, aligns the screen, and even changes the brightness and tone to match the colors of the walls and the light in the room. Digital zoom and focus improve the image even more without moving the unit, and the motorized adjustments (on compatible stands) make it even more accurate. BenQ’s AR Projector Planner app scans walls with your smartphone and suggests the best ways to set up your space. This makes what could be a difficult installation process easy.
Ultra-Low Latency for Gaming Skills
Thanks to its gaming-focused improvements, the TK705STi will be a worthy opponent and ally for gamers. It has an HDMI 2.1 port that can handle 4K at 60Hz and a very low 5ms input lag in game mode, which is great for fast-paced games like Call of Duty or Elden Ring. When compatible consoles detect Auto Low Latency Mode (ALLM), it turns on automatically. There are also dedicated HDR-RPG, HDR-FPS, and other genre-specific presets that change the visuals, audio, and latency for better performance. The short throw design also works well here, letting you get lost in a big screen in a small space without the input delay that other projectors have. The TK705STi makes sure that games run smoothly on PS5, Xbox Series X, or PC. It also supports eARC, which lets soundbars or AV receivers pass through audio without losing quality.
Smart Streaming and Connection Center
The TK705STi has Google TV (powered by Android 15) built in, so you can access over 5,000 apps right away, including Netflix, Prime Video, YouTube, and Disney+. No more dongles or extra remotes! You can search for and play content without using your hands with Google Assistant. You can also easily mirror your phone or laptop screen with Chromecast and AirPlay. There are two HDMI ports (one with eARC support), USB-C (with DisplayPort Alt Mode for docking a laptop), USB-A, and a 3.5mm audio out, so you can connect a lot of things. The built-in sound from the 8W stereo speakers is good enough for casual use, but it sounds even better when you connect to external audio. With a dedicated remote app for iOS and Android, you can even control everything over Bluetooth, which is a direct and stable link that doesn’t have any Wi-Fi problems.
The quality of the build and the user experience
BenQ put a lot of thought into making the TK705STi easy to use. Its small, modern case fits in with living rooms, and the on-screen menus are easy to use, with picture modes like Auto Cinema and Bright that let you make changes with just one tap. Early users on forums like Reddit have praised its clean look and dependable performance in low light, but some have said that the LED’s contrast isn’t as good as that of laser competitors in very dark rooms. With its 16:9 native aspect ratio and ability to be mounted on the ceiling, the projector is very flexible. It also comes with a full-metal stand for tabletop use, which makes it stable. Overall, people like it because it fills the gap between high-end cinema projectors and affordable smart devices. It gets high marks for being easy to use and a good value.
In the end
The BenQ TK705STi isn’t just a projector; it’s a powerful entertainment system that fits 4K HDR brilliance, low-latency gaming, and smart streaming into a short-throw package that’s perfect for homes that care about space in 2025. At an MSRP of $1,999, it has high-end features without the high-end hassle, making it a good buy for gamers, movie lovers, and people who like to stream. The TK705STi gives you the throw, the glow, and the wow factor to turn your living room into a movie theater.
