Frequently Asked Questions - LK954ST BENQ
How do I connect my laptop to the projector?
Use an HDMI cable to connect from your laptop to one of the projector's HDMI ports. Press the Source button on the remote or keypad to select HDMI. For older laptops, use the VGA port with a suitable adapter.
How often should I clean the projector filter?
Clean the air filter every 1,000 hours of use, or more frequently in dusty environments. Slide out the filter panel and vacuum or rinse with water (if washable). Allow it to dry before reinserting.
Can I use the projector without a screen?
Yes, you can project onto a white wall, but a projection screen improves brightness and contrast. Ensure the wall is flat and smooth for the sharpest image.
How do I replace the laser light source?
The laser module is designed to last up to 20,000 hours and may not require replacement during the projector's lifetime. If replacement is needed, contact BenQ service or a certified technician to replace the module.
What is the recommended throw distance for a 100-inch screen?
With a throw ratio of 0.8-0.98, the distance ranges from approximately 1.77 to 2.17 meters for a 100-inch screen. Use the zoom knob to adjust the image size.
How do I enable 3D playback?
Connect a 3D source (Blu-ray player) and set the projector to 3D mode. Put on DLP Link 3D glasses and ensure the 3D sync is working. You may need to adjust the 3D format in the display settings.
Why is my image blurry?
First, adjust the focus ring on the lens. If it remains blurry, check the resolution of the input signal and set it to the projector's native 4K UHD. Also ensure the projector is perpendicular to the screen.
Can I control the projector via network?
Yes, connect an RJ45 Ethernet cable to the projector. Use BenQ's network control software to manage the device via the LAN. RS232 control is also available for integration.
How do I reset the projector to factory settings?
Go to the Setup menu, select System, then choose Reset. Confirm the operation. This restores all settings to factory defaults.
What is the power consumption in standby mode?
The projector consumes less than 0.5W in standby mode when the power is turned off normally. Use the ECO mode to reduce power consumption during hours of use.
