Power-Saving, Eco Friendly

World-Leading SmartEco Technology for a Greener Environment

World-Leading SmartEco Technology for a Greener Environment

BenQ's own SmartEco Technology maximizes energy saving without compromising brightness and picture quality. What's more, the lamp has an unusually long life span.


Eco Blank Mode

The Eco Blank mode helps lower the total power consumption up to 70% by automatically dimming the lamp power. Activate Eco Blank mode when you need to direct the audience's focus back on you – or simply when the projector is not in use.

Eco Blank Mode

No Source Detected Mode

If turned on for over three minutes without a display source, the projector will automatically switch to Eco Blank Mode to eliminate unnecessary energy waste and prolong the life of the projector lamp.

No Source Detected Mode

SmartEco Mode

The SmartEco Mode cleverly adjusts the lamp power to maximize power saving by delivering the best contrast and brightness performance using only as much light as needed.

SmartEco Mode Long Lamp Life at up to 6500 hours

Long Lamp Life at up to 6500 hours

The MW821ST optimizes lamp life up to 6500 hours* - twice the average lamp life expectancy - reducing lamp changes and keeping maintenance to a minimum. (*Results will vary depending on environmental conditions and usage.)

Ultra-High Contrast Ratio

Ultra-High Contrast Ratio

An ultra-high contrast ratio projects sharp images, even for high brightness projectors. Get whiter whites and blacker blacks with a 13,000:1 contrast ratio


0.5W in Standby Mode

When inactive, the MW821ST complies with 2013 EU standards by keeping power consumption to a minimum of less than 0.5W on standby, extending lamp life and reducing energy costs.

Audio Pass Through

Audio Pass Through allows users to engage the projector's speakers in standby mode - conserving energy and preserving lamp life.

PointDraw 3.0 Pen (Optional)

The PointDraw 3.0 pen has been equipped with an Accelerometer for an improved writing experience. Exclusive coaxial design gives the most intuitive writing experience with QDraw3 Interactive Software. Pens are rechargeable via standard micro USB cable or by plugging into a specially-designed BenQ Charging cradle.

PointDraw 3.0 Pen (Optional)

3D Capability Improvement

The MW821ST supports HDMI, designed to maximize your audiovisual enjoyment* with the capacity to pass two simultaneous 1080p signals with one connection.
