Interlacing - Pre correction

In most cases you do not need to change this adjustment.

You may need to increase this adjustment only when the connected video and sync signal contains an abnormally big number of equalization pulses before the vertical sync (more than 8 lines), resulting in a phase error (geometry distortion) at the bottom of the image.

Interlacing - Post correction
