What customers don't like about BenQ TK705STi

  • Limited black levels and contrast; dark scenes can appear greyish or washed out in dedicated home theatres
  • High operating fan noise, especially when running in the brightest lamp modes
  • The included remote control lacks backlighting, making it difficult to use in dark viewing environments
  • Native Netflix app is not supported on the included Android TV dongle due to licensing issues
  • Built-in 5W speaker lacks depth and bass, requiring external audio for a true cinema experience
  • Keystone correction is disabled when using the fastest gaming modes, making physical placement critical

Verdict

The BenQ TK705STi is a short-throw 4K HDR LED projector optimized for both home cinema and high-performance gaming in compact spaces. It delivers 3,000 ANSI lumens of brightness and features an ultra-low input lag of 5ms at 4K/60Hz, alongside dedicated HDR game modes (FPS, RPG) and integrated Google TV for smart streaming. Its short 0.8 throw ratio allows for a 100-inch display from just 1.8 metres away, supported by 98% Rec. 709 color coverage and automatic 2D keystone correction for flexible setup. While it excels in brightness and responsiveness, reported drawbacks include relatively high fan noise during intense operation, a lack of deep black levels in dark-room settings, and the potential for rainbow artifacts common to single-chip DLP systems.
