Plane Downscaler

Chroma plane downscaler used during YUV to RGB conversion. This filter controls how chroma planes are downscaled when the source resolution exceeds the display resolution.

Default: None (none) -- follows the main downscaler setting.

  • None is the default and uses the same filter as the main Downscaler, which is appropriate for most use cases.
  • A separate plane downscaler is rarely needed. Consider setting one only if you want to use a cheaper filter for chroma to reduce GPU load during downscaling.
