BenQ TH671ST

The BenQ TH671ST DLP projector boasts stunning image quality and has a native resolution of 1920 × 1080 which, when combined with a luminosity of 3000lm and enhanced 10,000:1 contrast, ensures sharp and crystal clear image quality for company presentations, football matches, feature films and more. It does not matter at what time during the day you are watching, as the image perfectly adapts to the light level in the room due to clever LumiExpert technology.

With Lamp Save mode, the projector offers a lamp life of up to 7000 hours. It also features SmartEco technology to save energy, and supports 3D projection. Rich connectivity options include D-Sub, HDMI, HDMI with MHL 2.0, USB, and USB mini.

Short projection distance

Even in rooms where you can not afford to place your projector very far from the canvas, you can enjoy image with a diagonal of 2.5 meters. The BenQ TH671ST can create such stunning image from the distance of just 1.5 meters.

Short projection distance

Exceptional sharpness and realistic colours for several years

BenQ, the world leader in DLP projectors, offers flawless image quality that you can enjoy for years. This projector makes use of Digital Light Processing technology from Texas Instruments, patented BrilliantColor technology, and a filter-free design with an almost closed construction that provides:

  • Exceptional image quality
  • High sharpness with excellent readability
  • Bright, faithful colours

Missing signal detection

The projector automatically switches to Eco Blank mode after the BenQ TH671ST has been turned on for more than three minutes without a signal input. This eliminates unnecessary waste of energy and prolongs the life of the projection lamp.

In Eco Blank mode, the lamp is capped to 30% power. This is great for presentations, for example; when the slide hasn't been changed in a few minutes (due to ongoing discussion etc.), it makes the audience naturally focus more on the speaker than the canvas.

Energy-saving, environmentally conscious

BenQ's SmartEco technology has pushed the boundaries of what is expected from a DLP projector. It brings lower maintenance costs, brightness without compromise, great image quality and optimized lamp life. With this special innovative technology, you can save up to 70% of the lamp's energy consumption and reduce maintenance costs through dynamic energy-saving features, providing you with an extremely high quality and vibrant image.

LampSave mode

The cost of replacing the projection lamp accounts for the bulk of the total cost of the projector's operation. LampSave dynamically adjusts lamp performance according to the brightness of the projected content, which dramatically extends lamp life by 50%.
