Wall Flatness Adaptation helps compensate for minor wall surface irregularities to improve image geometry.

Enable Wall Flatness Adaptation
1. Press the Settings button on the remote to open Quick Settings, then select All Settings.
2. Navigate to: Projector > Keystone
3. Select Wall Flatness Adaptation
4. Scan the QR code displayed on the projector using your smartphone.
- The projector will display a checkerboard calibration pattern.
- Your phone will automatically open the calibration webpage.
5. Hold the smartphone horizontally and point it directly at the projected image.
- Ensure the entire checkerboard pattern is visible in the camera frame.
- Wait until the image is in focus and take the photo.
Note: Ensure the projected image is clear and unobstructed.
6. After calibration is completed, compare the Before Correction and After Correction results and save your preferred version.
- Both the projector and smartphone must be connected to the internet.

Notes
- Wall Flatness Adaptation should be performed after completing all Keystone Correction adjustments. Running Keystone Correction afterward may override the wall flatness calibration results.
- This feature can reduce image distortion and wave-like edge effects caused by projecting onto uneven walls. However, it cannot completely eliminate such effects. For optimal image quality, a dedicated UST projection screen is strongly recommended.
