What to Check First
- The wall onto which the image is projected is slanted.
- The image is projected onto a black wall (screen), which may affect the sensor’s accuracy, and cause its operating distance to decrease.
- Direct sunlight is hitting the sensor.
- The wall or screen is positioned at a distance or angle outside the Auto Adjustment feature’s supported range.
- Make sure the wall (screen) and projector are at right angles (perpendicular) to each other.
- Avoid projecting onto black surfaces.
- Keep the sensor out of direct sunlight.
- Ensure the angle of projection is within 5°.
- Keep the projection distance between the projector and wall/screen within 40cm.
- Remove any objects between the projector and wall/screen.
Why This Can Happen
Symptoms can have more than one cause, and the correct steps depend on the exact model, installation and operating conditions. Use the checks above to narrow the issue before service.
