Frequently Asked Questions - MP722 BENQ
How do I clean the lens of the BenQ MP722 projector?
Use a soft, dry cloth to gently wipe the lens. For stubborn dirt, lightly moisten the cloth with lens cleaning solution (isopropyl alcohol) and wipe gently. Never spray liquid directly onto the lens.
How often should I replace the lamp?
The lamp typically lasts 3000-4000 hours in normal mode. When the power indicator blinks red and a message appears on screen, replace the lamp with a BenQ 5J.J8D05.001 or equivalent. Always allow the projector to cool before replacement.
How do I connect a laptop to the MP722 projector?
Connect a VGA cable from your laptop's VGA port to the projector's VGA input (marked 'COMPUTER'). If your laptop has only HDMI, use an HDMI-to-VGA adapter. Select the correct input source by pressing the 'SOURCE' button on the remote or control panel.
The image is keystone distorted. How do I fix it?
Use the keystone correction feature. Press the 'KEYSTONE' button on the remote, then adjust the distortion using the arrow keys until the image is rectangular. The MP722 supports ±40° vertical adjustment.
How do I clean the air filter?
Turn off and unplug the projector. Open the filter cover (located on the side). Remove the filter and clean it with a vacuum cleaner or wash it with mild soap and water if very dirty. Ensure it is completely dry before reinstalling. Clean every 100 hours of use.
Can I use the projector without a remote control?
Yes, the projector has a control panel on top with basic buttons: power, menu, source, arrow keys, and keystone. However, the remote provides convenient access to all features including zoom, freeze, and blank functions.
What is the native resolution of the MP722?
The native resolution is XGA (1024 x 768). It can accept higher resolutions up to 1920x1200 (UXGA) but will downscale them to XGA for display.
How do I reset the lamp timer after replacing the lamp?
Go to the on-screen menu (press MENU), navigate to SYSTEM SETUP: ADVANCED > LAMP SETTINGS > LAMP HOUR. Select RESET and confirm. This clears the lamp hours and turns off the replacement reminder.
The projector turns off after a few minutes. Why?
This could be due to overheating. Check that the air filter is clean and that the projector has adequate ventilation (at least 30 cm clearance on all sides). Also ensure the fan is running. If the problem persists, the thermal sensor may be faulty.
How can I improve the image brightness?
Set the projector to Bright mode in the picture menu. Reduce ambient light in the room. Use a high-gain screen if possible. Also check that the lens is clean and that the lamp is not nearing the end of its life.
