Frequently Asked Questions - MW721 BENQ
How do I connect my laptop to the MW721 projector?

How often should I replace the lamp?
The lamp lasts up to 10,000 hours in SmartEco mode. When the lamp warning indicator turns on or the image becomes dim, replace the lamp. Refer to the lamp replacement section in the manual for steps.
Can I watch 3D content on this projector?
Yes, the projector supports 3D projection when connected to a 3D-capable device using an HDMI cable. You need to enable 3D in the projector menu and use compatible DLP Link 3D glasses.
How do I clean the air filter?
Turn off the projector and unplug it. Locate the air filter on the side, remove it, and gently clean with a vacuum cleaner or soft brush. Avoid water. Replace the filter after cleaning. Clean every 1000 hours to prevent overheating.
What is the recommended projection distance for a 100-inch screen?
With a throw ratio of 1.55 - 1.86, for a 100-inch screen, place the projector at a distance between 3.3 and 4.0 meters from the screen. Check the manual for other sizes.
How do I reset the lamp timer?
Go to the Settings menu, select Lamp Settings, and choose Reset Lamp Timer. Confirm when prompted. This should be done after replacing the lamp.
Why is the projector not turning on?
Check that the power cable is securely connected and the power outlet is working. Make sure the power button is pressed, and the Standby LED is lit. If the thermal or lamp LED flashes, wait for the projector to cool down.
Can I use this projector for presentations in a bright room?
Yes, with 3000 ANSI lumens, it performs well in rooms with moderate ambient light. For best results, dim ambient lighting and use a high-contrast screen.
How do I adjust the keystone correction?
Use the Keystone button on the remote or navigate to the menu. Adjust the vertical keystone (-30 to +30 degrees) until the image is rectangular.
What should I do if the projected image is blurry?
Use the focus ring on the lens to sharpen the image. Also, verify the projector is at the correct projection distance and the resolution set on your device matches the native WXGA resolution.
