Frequently Asked Questions - MX666+ BENQ
How do I replace the lamp in my BenQ MX666+?
Turn off the projector, unplug it, and let it cool for at least 30 minutes. Remove the lamp cover, loosen the lamp screws, and pull out the old lamp. Insert the new lamp (model 5J.J9T05.001), tighten the screws, and replace the cover.
Can I use a 4K source with this projector?
The MX666+ has a native XGA (1024x768) resolution. It can accept 4K input but will downscale to its native resolution.
How do I clean the air filter?
Remove the filter cover, take out the filter, and gently vacuum or wash it with mild detergent. Allow it to dry completely before reinstalling. Clean every 500 hours of use.
What is the recommended projection distance for a 100-inch screen?
For a 100-inch diagonal image, the projector should be placed between approximately 3.2 and 3.9 meters (10.5 to 12.8 feet) from the screen, depending on zoom.
Why does the projector turn off after a few minutes?
This may be due to overheating. Check that the air filter is clean and the vents are not blocked. If the lamp has reached its end of life, it will also power off.
How can I connect my laptop to the projector?
Use a VGA cable (or HDMI if your laptop supports it) to connect from your laptop output to the appropriate input port on the projector. Then select the correct input source via the Source button on the remote or control panel.
Does the projector support 3D content?

What is the lamp life, and when should I replace it?
