Bezel and Gap Compensation
Display devices have a region where video data is not displayed. This area is called the
bezel . Bezel compensation takes this area into account when a single video source is
mapped across multiple displays. It is recommended, when a video wall is set up for the
first time, that bezel compensation values be set to zero. Bezel compensation can be
adjusted at any time.
The illustration on the left shows a 2x2 video wall without bezel compensation. Note how
the circle is stretched, slightly, horizontally. On the right, bezel compensation is used to
correct the “distorted” image.
1. Access the Web interface for the Sender unit.
2. Login as “Administrator” or “User”.
3. Click the Video Wall tab.
4. Adjust the values under the Bezel and Gap Compensation window group. Refer
to the diagram, to the right of each field, to see the effect of each value. All entered
values are applied to the physical displays in 0.1 millimeter increments.
