Answer/Steps

If the resolution of the video display's surface does not match video format's aspect resolution, the image must be scaled and /or cropped to match the native resolution of the display. Scaling is the process of converting image data from one resolution to another resolution.  This involves a mathematical adjustment of individual pixels.  The quality of the image can be impacted by an image that is not properly scaled.

Scaling Guidelines

1:1

  • No filtering, perfect pass-through

Upscaling

  • Tested up to 1:17

Downscaling

  • BEST quality, limit planned scaling to 1.2:1.
  • GOOD quality, limit planned scaling to 2:1.
  • OK quality, limit planned scaling to 3:1.

The machine won’t break past 3:1, but incoming data samples will include lots of aliasing and lost fine detail. This is still useful for transition effects but isn’t recommended for static setups.
