Frequently Asked Questions - MW826STH BENQ
How do I replace the lamp on the BenQ MW826STH?
Turn off the projector and unplug it. Wait 45 minutes for cooling. Remove the lamp cover screw, then the lamp module. Insert new lamp (model 5J.J6L05.001) and secure. Reset the lamp timer via menu.
How can I clean the air filter?
Turn off and unplug the projector. Open the filter cover on the side. Remove the foam filter and clean it with a soft brush or vacuum. Reinstall and close cover. Clean every 3000 hours.
What is the short throw ratio and why is it useful?
The throw ratio is 0.6, meaning you can project a large image from a short distance. This minimizes shadows and is ideal for small rooms or interactive whiteboards.
How do I connect my laptop to the projector?
Use an HDMI or VGA cable. Connect one end to your laptop, the other to the projector. Select the correct input source via the remote or projector buttons.
Can I use the projector without a remote?
Yes, the projector has control buttons on the top panel: Power, Source, Menu, and navigation arrows. The remote offers convenience but is not required for basic operation.
Why is there no image but the power LED is on?
Check if the lens cap is removed. Ensure the correct source is selected. If using HDMI, verify the cable is secure. Try restarting both the projector and source device.
How do I reset the lamp timer?
After replacing the lamp, press Menu, navigate to System Setup > Lamp Settings > Lamp Reset. Confirm by pressing OK. The timer will reset to 0.
What is the maximum projection size?
For a 100-inch diagonal screen, the projector must be placed about 1.2 meters away due to the short throw. The max size is limited by ambient light and brightness.
Does the projector support 3D?
Yes, the MW826STH supports DLP 3D via HDMI 1.4a. You need compatible 3D glasses and a 120Hz signal source. Enable 3D in the display menu.
How do I mount the projector on the ceiling?
Use a compatible ceiling mount (e.g., BenQ CMG2). Attach the mount to the projector using the three screw holes on the bottom. Secure to ceiling structure. Ensure ventilation clearance.
