Enjoy your video games and multimedia content on a big screen with the BenQ TH671ST Full HD DLP Home Theater Projector. It features 3000 ANSI lumens of brightness and a 10,000:1 dynamic contrast ratio, plus a number of features to enhance color accuracy. The projector has two HDMI inputs, one of which is MHL-compatible, for connecting your digital HD devices such as a gaming console, Blu-ray player, or cable/satellite box. The MHL-compatible HDMI input accepts wired connections from your smartphone or tablet for mirroring. Its built-in 5-watt speaker eliminates the need for external speakers if none are convenient. The TH671ST includes a VGA cable and an IR remote control.

Take Video Games to the Big Screen

With Full HD resolution, 3000 lumens of brightness, a low 16.67 ms input lag, a 5W built-in speaker, and a simplified setup, the TH671ST can expand your gaming world.

Fast Response for Smooth Gaming

The TH671ST brings a low 16.67 ms input lag and microsecond DMD response time for a smooth gaming experience without unwanted motion blur and image lag.

LumiExpert Technology

BenQ's LumiExpert technology is designed to actively detect ambient light conditions in your viewing environment and automatically adjust visual brightness.

Dedicated Picture and Sound Modes

The TH671ST features Cinema, Music, Sports, and Game modes to customize your entertainment experience.

3000 Lumens of Brightness for Lights-On Enjoyment

The 3000-lumen brightness level lets you enjoy your media with the lights on, making it well suited for living rooms and group settings.

Short Throw Ratio for Nearly Any Space

The TH671ST needs only 5' to project a 100" image, reducing space constraints and setup hassles.

Vertical Keystone Correction

Countering the trapezoid effect when the projector is placed off center relative to the vertical axis, vertical keystone correction adjusts the image for a squared-off image, making it easy to project from a tabletop or a ceiling mount.

Designed for Sharp Detail Clarity

DLP technology is able to produce well-defined sharpness in images and text by enhancing the fill ratio of individual pixels and employing SmartEco Technology.

Wireless Streaming with Optional Adapter

The optional QCast Mirror HDMI wireless adapter can instantly stream videos and photos from your compatible mobile devices to the big screen.
