The Window output is exceptional in that it is the only output target that is not disk file based. You can use it for previewing file rendering progress in real time. It has one option:

  • Dither Scale: Defines the amount of RGB dithering. The dithering value is scaled automatically to match the bit depth of the current display mode. The window output specific dithering operates on the already byte converted data stream, and therefore the dithering accuracy is maximally 1/255 units. Therefore, it is irrelevant for 24 bit display modes. The default value 0.3 is optimal for 16-bit graphics.

[Note] Note
You can use render settings dithering for high accuracy dithering below 1/255 unit boundary.
