With the new BenQ TK705i and TK705STi projectors, the Taiwanese brand offers two all-in-one 4K models designed to meet home theater requirements. Whether it’s with movies, sporting events or video games, these devices boast excellent picture quality, high brightness and ease of installation, appealing to both amateurs and technophiles looking for high-performance, yet easy-to-use equipment. How can these two BenQ projectors transform your living space into a real projection room?

BenQ TK705i and TK 705STi: bright, accurate 4K picture
The BenQ TK705i and TK705STi projectors use DLP technology to deliver 4K UHD resolution (3,840 x 2,160 pixels) and 3,000 lumens of brightness, ideal for both dark and bright rooms. Thanks to in-house CinematicColor technology and 98% coverage of the Rec.709 color space, the hues displayed are rich and precise.
HDR-PRO and HDR10+ technologies are also included for improved contrast management and enhanced image depth. The result: a faithful reproduction of the director’s intentions, whether in film or HDR gaming mode.
🧾 Expert's note
HDR-PRO and HDR10+: what's the difference?
The BenQ TK705i and TK705STi projectors support two dynamic image enhancement technologies: HDR-PRO and HDR10+.
🔎 HDR-PRO is a BenQ proprietary technology that dynamically adjusts brightness and contrast according to the content displayed. It combines two processes:
- LCE (Local Contrast Enhancer): local contrast enhancement,
- GCE (Global Contrast Enhancer): global optimization of light dynamics.
🔎 HDR10+, meanwhile, is an open standard that enables the projector to adapt frame by frame thanks to dynamic metadata, for a rendering that is more faithful to the director's intentions, particularly in dark or high-contrast scenes.
These technologies ensure clearer details, whether in shadows or bright areas, for a more nuanced and realistic picture.
Quick and easy installation
The BenQ TK705i and TK705STi feature a series of automatic image adjustment functions designed to make life easier for users. Focusing and keystone correction are automatic, as is on-screen adjustment. The TK705i boasts a 1.3x motorized optical zoom, making it easy to adjust to different screen sizes without moving the device. The TK705STi, meanwhile, is equipped with a short-throw lens (0.8:1 throw ratio), enabling it to project a large image when installed close to the wall: an asset for small spaces.
Instant entertainment with Google TV
Both projectors are Google TV certified and offer direct access to platforms such as Netflix, Disney+, Prime Video, AppleTV+ and YouTube, without the need for additional devices. The interface is fluid, intuitive and compatible with voice commands. This native integration makes them fully autonomous entertainment hubs, capable of adapting to all domestic uses, from movie nights to impromptu gaming sessions with friends.

Also designed with gamers in mind, the BenQ TK705i and TK705STi feature HDMI 2.1 connectivity with ALLM (Auto Low Latency Mode) support, and boast a very short response time: just 5ms in 4K/60Hz. Dedicated picture modes such as HDR RPG and HDR FPS optimize rendering for different types of games. The USB-C port with 30W power supply makes it easy to connect a portable console or computer, without the need for an additional adapter.
Compact and easy to integrate
With their compact, unobtrusive design (approx. 3.8kg), these two projectors fit easily into any modern interior. They can be placed on furniture, ceiling mounted or used with the optional BenQ ST30 desk base.
“The TK705i and TK705STi are designed to fit your lifestyle, and most importantly, deliver a pristine 4K image any time of day,” sums up Peter Huang, President of BenQ Corporation.
