Why is there no image projected?
Check that the projector is powered on and the lens cap is removed. Ensure the input source is correct (HDMI, VGA, etc.). Verify the cable connections. If the lamp indicator flashes, the lamp may need replacement.
How can I connect my laptop to the projector?
Use an HDMI or VGA cable to connect your laptop to the projector. Ensure the projector is set to the correct input. If using HDMI, audio and video are transmitted; for VGA, a separate audio cable may be needed.
What is the keystone correction range?
The projector offers vertical keystone correction of ±40 degrees. Use the keystone buttons on the control panel or remote to adjust the image geometry.
Can I use the projector for gaming?
Yes, but the input lag may be noticeable. Use the 'Game' picture mode if available to reduce latency. Ensure a good HDMI cable for best performance.

After replacing the lamp, go to the OSD menu (press Menu). Navigate to Setup > Lamp Settings > Reset Lamp Hours. Select Yes and confirm. The timer will reset to zero.
What is the recommended screen size?
For best viewing, the projector can display from 30 to 300 inches diagonally. The optimal size depends on room conditions; typical sizes are 80-120 inches for home theaters.
How do I adjust the focus and zoom?
Use the focus ring on the lens to sharpen the image. Use the zoom ring to adjust the image size. First, position the projector at the desired distance, then fine-tune focus and zoom.

Ensure vents are not blocked. Clean the air filter. Place the projector in a well-ventilated area. If the temperature warning appears, turn off the projector immediately and let it cool before restarting.
