The BenQ TH685: A Versatile Home Theater and Gaming Projector 

When it comes to choosing a projector that strikes a balance between immersive home theatre experiences and sharp gaming visuals, the BenQ TH685 positions itself as a strong contender. Released in 2020, this projector was designed with dual-purpose usage in mind: enhancing movie nights with vibrant picture quality while delivering the responsiveness and clarity demanded by gamers. Based on its engineering data, the projector boasts an impressive mix of features, from Full HD 1080p support and 4K upscaling capabilities to a high 3500 ANSI lumens brightness output, making it adaptable to different lighting environments. But does it really live up to its numbers for both casual viewers and gaming enthusiasts? Let's delve into its specifications and see what stands out most.

Detailed Specs & Features

On paper, the BenQ TH685 offers solid optical performance anchored by a 1080p native resolution with support for 4K input, which means users can enjoy enhanced clarity, especially when paired with UHD sources. The 3500 ANSI lumens brightness output and HDR10 & HLG HDR formats ensure vivid images even in moderately lit rooms, a crucial factor for home entertainment and gaming alike. The projector's 10,000:1 contrast ratio promises deep blacks and good differentiation in scenes, backed by a 95% color gamut coverage and 10-bit colour processing for smooth gradient transitions and accurate colour reproduction. For setup versatility, the projector supports a throw ratio of 1.0-1.5 and a minimum throw distance of 3.2 feet, allowing for flexible placement options across rooms of different sizes. It supports up to a massive 300-inch screen size, which is exceptional for creating a true cinematic experience at home. The device offers automatic vertical keystone correction up to 40 degrees and a minor lens shift, making alignment easier without complex manual adjustments. Under the hood, it uses a powerful lamp-based light source rated at 245 watts, offering a longevity of up to 15,000 hours in eco mode, reassuring for long-term use and maintenance costs. The projector incorporates a standard DLP chip (0.48 inches) and an image processor optimised for 10-bit depth colour processing, ensuring that picture quality aligns with modern content standards.

Design & Build

The all-white plastic chassis reflects typical projector construction, prioritising lightweight and ease of installation over ruggedness. At just 6.2 pounds, it's portable enough for moving between setups, yet its solid rear ventilation and standard chassis reinforcement suggest stability during extended usage sessions. Its compact 12" width and 9" depth make it unobtrusive on a tabletop or ceiling mount, supported by the projector's tabletop and ceiling mounting compatibility. The clean design also includes a 3.5mm audio output and VGA port, which offers compatibility with a variety of older devices.

Performance

In daily use, the BenQ TH685 should shine with its 120Hz refresh rate, making it particularly attractive for gaming, where smooth motion is vital. Its minimal motion processing and sharpness enhancement settings indicate a natural, unprocessed image that gamers often prefer due to minimal lag and artifacting. The wired input lag of 8ms is notably low, making it a commendable choice for competitive and fast-paced games. Combined with customizable sound mode, movie, music, play, and speech, and a decent 5W mono speaker, the device covers audio-visual needs without requiring an external sound system immediately.

Extra Features 

While the device does not feature smart functionality, built-in apps, or wireless connectivity such as Bluetooth or Wi-Fi, its inclusion of two HDMI 2.0 ports and a USB-A port ensures ample wired connectivity options. Auto source detection and quick settings on-screen menu make navigation straightforward, even though the projector lacks advanced software calibration or AI optimisations. The warranty coverage of 3 years adds a level of trust, backed by global service availability that reassures buyers of consistent support.

Pros & Cons

While it misses out on on-board streaming and wireless convenience, buyers intending to use external media players or gaming consoles won't be at a loss. For households and gamers looking to prioritise image quality and responsiveness rather than smart features, this model lives up to its billing.

Quick Take

In short, the BenQ TH685 is a solid mid-range projector that impresses with bright visuals, flexible installation, and sharp gaming performance thanks to its low input lag and high refresh rate. If we look at the numbers alone, this projector delivers a compelling blend of home theatre brightness and gaming speed without unnecessary bloat, ideal for users who connect external streaming devices.
