Projector BenQ MW561 WXGA 4000 ANSI lumens with 20W speaker

BenQ MW561 is a WXGA DLP projector with 4000 ANSI lumens brightness and a built-in 20W speaker. It delivers 1280 x 800 native resolution images with a 16:10 aspect ratio and uses a lamp light source with multiple lamp-life modes. The projector is intended for classrooms, meeting rooms and presentation environments where clear, bright projection and integrated audio are required, and it supports common video and PC connections including HDMI, D-Sub and USB.

Advantages

The projector combines high brightness with WXGA resolution to produce readable images in well-lit rooms. A built-in 20W speaker provides audio without external amplification, while multiple lamp modes extend lamp life up to 15,000 hours in the most conservative setting. Vertical keystone correction of ±40° and a flexible throw ratio simplify installation and image alignment. Noise level and power consumption are balanced for classroom and meeting-room use.

• Classroom lectures and educational presentations
• Business meetings and conference rooms
• Training sessions and seminar halls
• Displaying slides, videos and multimedia content

How to use

Place the projector on a stable surface or mount it according to the throw ratio to achieve the desired image size. Connect a video source via HDMI, D-Sub or USB as supported, and connect audio devices through the 3.5 mm jack if required. Use vertical keystone correction to correct image trapezoid distortion and adjust projector position for proper focus. Select an appropriate lamp mode (Normal, SmartEco, LampSave or ECO) depending on brightness needs and desired lamp life. Follow the user manual for ventilation clearance, lamp replacement and routine maintenance.

Usage recommendations

For consistent image quality and longer lamp life, operate the projector in SmartEco or ECO modes in well-lit rooms when maximum brightness is not required; ensure adequate ventilation and avoid operating above 40 °C. Regularly clean filters and replace the lamp according to the indicated hours to maintain performance.
