BenQ TH575 vs BenQ TH685i: A Comprehensive Comparison of Key Gaming and Home Theater Projectors 

The BenQ TH575 and BenQ TH685i are both DLP projectors built primarily for home theater and gaming enthusiasts, sharing a strong foundation in 1080p native resolution and smooth 120 Hz refresh rates. While they target similar audiences, they diverge in several significant aspects, such as smart capabilities, optical performance, and usage scenarios. The TH575, released in 2023, focuses on delivering high brightness and superior contrast, making it an excellent budget-friendly choice for indoor entertainment. On the other hand, the 2025 TH685i adds advanced features, including 4K input support, Android TV integration, and outdoor use certification, catering to users who value versatility and smart connectivity. 

What Makes the BenQ TH575 Stand Out?

The TH575 boasts a brighter projection output of 3800 ANSI lumens and a higher static contrast ratio of 15,000:1, ensuring more vivid visuals with deeper blacks compared to the TH685i's 10,000:1 contrast. This projector's 1080p native resolution and 120 Hz refresh rate deliver smooth and sharp images that suit fast-paced gaming and cinematic viewing. Its shorter minimum throw distance of 2.42 meters makes it more flexible for limited spaces, and it includes auto vertical keystone correction to simplify setup.

The TH575's lens system has a slightly larger aperture size of 2.56, allowing greater light admission. The projector supports multiple color calibration profiles such as sRGB, Rec709, Cinema, and Game, ensuring tailored color reproduction for different content types. Its light source is designed for longevity with a 6,000-hour lamp life in normal mode, outperforming the TH685i in this regard.

Though it lacks built-in smart functions, the TH575 compensates with a backlit remote for easier control in dark environments and comprehensive connectivity, including two HDMI 1.4 ports. Its audio system features a robust 10W mono speaker capable of decent sound output for casual use. For power management, it operates at a moderate 280W in normal mode and supports universal voltage input, suitable for global usage.

The Advantages of the BenQ TH685i

While the TH685i may project slightly less brightness at 3500 ANSI lumens and possess a lower aperture size (2.07), it compensates with remarkable smart features and connectivity designed for the modern user. It supports a significantly higher maximum resolution input of 4K, future-proofing the projector for evolving UHD content.

The biggest leap is the integration of Android TV. The TH685i comes with an intuitive operating system that includes popular streaming apps such as YouTube, Prime Video, and Disney+, voice control, and wireless casting capabilities supporting standards like AirPlay and Chromecast. This eliminates the need for additional streaming devices and makes content access seamless.

Another highlight is its excellent color performance, which covers 95% of the color gamut, surpassing the TH575's 88%, while supporting wider HDR formats including both HDR10 and HLG. With low input lag at 8.3ms, it's optimized for competitive gamers who demand responsiveness.

The TH685i provides more versatile connectivity options, including HDMI 2.0 for better 4K handling and a rare VGA port, broadening compatibility with legacy devices. Its vertical lens shift of 5% adds to flexible installation setups, complemented by advanced parental controls and rapid input switching speed (0.5 seconds), ensuring a smooth user experience.

Also suitable for outdoor entertainment, the TH685i is rated for outdoor use and comes with an extended warranty. It'ss more efficient eco mode draws less power (206W) compared to normal mode, helping save energy during prolonged use.

Quick Take

The BenQ TH575 impresses with exceptional brightness, contrast, and an affordable price tag, making it a solid choice for classic home theater setups and gaming. Meanwhile, the TH685i shines with its smart capabilities, 4K input support, and wider color gamut, tailored for tech-savvy users looking for future-proof features and flexible use cases, including outdoor viewing.

Bottom Line Recommendation

For those who prioritize optical performance and value without breaking the bank, the TH575 offers superior brightness and contrast alongside a comfortable lamp lifespan. However, if you want the latest smart projector with Android TV, 4K input, enhanced color depth, and features geared towards mixed indoor and outdoor use, the TH685i is worth the premium investment.

Verdict

  • Winner: BenQ TH575 - Delivers higher brightness, better contrast, longer lamp life, and excellent overall image quality at a reasonable price.
  • Runner-up: BenQ TH685i - Offers superior smart features, 4K input support, a broader color gamut, and more connectivity options, but comes at a higher cost.
