11.9.2 Blend & Blend mask
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 set up basic blend zones?
1. In the main menu, select Installation → Blend and Mask → Blend mask .

2. To enable the blend mask, put the Enable slider to the right. The color of the slider becomes blue when
enabled.
3. To project masking lines on the screen, put the Show lines slider to the right. The color of the slider
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 helping lines are activated, you will get a visual indication of the screen of the installed blending
area.
