Lens Distortion Correction
Open Screen Configuration → Lens → Distortion Correction. On the Lens Distortion page, adjust Distortion Correction while watching the alignment grid.

- Negative values compensate for observed barrel distortion.
- Positive values compensate for observed pincushion distortion.
- 0.00 applies no correction.
Reset Lens Correction returns this control to zero. Distortion correction is independent of the anamorphic enable switch and does not reset the screen ratio or lens expansion.
