Brilliant Visual Performance

High Resolution

High Brightness and Whisper Quiet 31dB

High Contrast Ratio
The 20000:1 high contrast ratio ensures that every text, image, graph, chart and video is projected with optimal clarity and enhanced sharpness, especially for numerical data. This enables presenters to view their presentation files clearly and allows the audience to stay focused on the contents projected.

Independent 3D Color Management for Six Primary Colors
BenQ’s exclusive 3D color management tool ensures 100% uncompromised color customization with the freedom to independently fine-tune the hue, grain and saturation levels of all six primary colors (R/G/B/C/M/Y).

Easy & Hassle-free Setup

Auto Vertical Keystone
Auto vertical keystone correction enhances installation flexibility by correcting the trapezoid effect via vertical adjustments up to +-40 degrees. With it, the projector can be placed off center and the presenter can stand in front of the screen without blocking the image.


Big Zoom for Big Pictures in Any Space
1.3x Big Zoom feature frees up space with an impressive range of throw distances and projects images up to 300" wide, giving you the flexibility of placing the projector anywhere without compromising your current decor.

Simple Operation

Full HD Wireless Presentation via Your Smart Device by Qcast (Optional)

And a new control panel keeps all projector controls at your fingertips. The simple plug & play QCast WiFi dongle is even designed to plug into a hidden port, keeping the minimalist design uncluttered.

* Optional QCast WiFi dongle available separately.

Power Saving, Eco Friendly

World-Leading SmartEco Technology for a Greener Environment
As the first DLP brand to incorporate Philips' ImageCare technology into its projector lamp system, BenQ has taken a further leap, developing its own SmartEco Technology to perfect what DLP can do for energy saving. Built with this brand new invention, the MU686 brings together uncompromised brightness, exquisite picture quality and optimized lamp life through innovative features.

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.


Normal Mode
260W Projector Power Consumption by Average


SmartEco Mode
Enhanced Details in Darkened Scenes 210W Projector Power Consumption by Average

EcoBlank Mode
If the projector is detected to be without a display source for over three minutes, the system will automatically switch to EcoBlank Mode, eliminating unnecessary energy waste and prolonging the life of the projector lamp.


Source Detected 100% Lamp Power


No Source Detected 30% Lamp Power

Auto Power Off
If the projector is found to be without a display source, the system will automatically turn off the projector, eliminating unnecessary energy waste and prolonging the life of the projector lamp.

0.5W in Standby Mode
When inactive, the MH750 keeps power consumption to a minimum (<0.5W standby power), achieving what was once a challenge for earlier projector models. This technological advancement in energy saving helps lower energy costs.
