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

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 after the vertical sync (more than 8 lines), resulting in a phase error (geometry distortion) at the top of the image.

SH Compensation (optional)

If your display is equipped with the Southern Hemisphere option, the on-screen display menu contains additional functions to adjust the image geometry. If the option is not installed in the display, this menu does not appear.

SH Compensation - SH Compensation ON/OFF

For proper geometry adjustment in the Southern Hemisphere, you must switch SH Compensation ON. If not, the SH controls will not function.
