About masking and blending width or height
Offset is used to clip the image on one or multiple sides (masking). This is used to hide parts of the picture that
should not be shown on the screen. For example: if the source is a Windows PC, you can hide the menu bar
using this method.
The larger the Mask value, the more the image is masked (by black bar) at the corresponding side. E.g. Top
mask of 100 will blank the top 100 lines.
Height or width is used to create a blending zone with a smooth brightness drop off. This is used to
compensate for the double brightness in overlap areas. The value is the size of the blended area in pixels.
How to adjust blend zones?
1. In the main menu, select Installation → Blend and Mask → Blend – Mask.

becomes blue when enabled.
4. Determine the start position of the mask (1) for the masking height and width, together with the desired size of
the mask (2) to determine the width of the masked area.
When the blending lines are activated, you will get a visual indication of the screen of the installed blending
area.
