1. When referring to a computer monitor or another display, interlace or interlacing is a description of how the picture is created. With an interlaced display the picture is created by scanning every other line, and on the next scan, scanning every opposite line.

What is interlacing and non interlacing?

In an interlaced monitor, the electron beam takes two passes to form a complete image: it skips every other row on the first pass, and then goes back and fills in the missing rows. A non-interlaced monitor does the whole job in one pass, tracing each row consecutively.

What causes interlacing?

The faster the video frame rate, the less time there is between each interlaced field. ... Slower video frame rates produce more pronounced interlacing artifacts.
