Adjusting For Edge Blending And Mullion Compensation - Extron electronics Quantum Ultra Series User Manual

Maximum rotated output signals for each OUT4HDMI and OUT4DTP output
card
The following example shows the number of rotated output signals that are supported on
each standard HDMI output card at different resolutions and refresh rates.
Example 1: Two rotated 1080p outputs at 60 Hz (connectors 1 and 3 disabled)
Example 2: One rotated 4K output at 30 Hz (connectors 1, 2, and 3 disabled)

NOTES:

Adjusting for Edge Blending and Mullion Compensation

When setting up the videowall, you can select test patterns via VCS that help you define
the following adjustments:

See the VCS Help File for instructions on adjusting to compensate for mullion and edge
blending.

Edge blending compensation (Quantum Ultra and Ultra II 610 and 305 only)
— In certain situations it may be desirable to create an overlap of video between
adjacent displays. This overlap melds the two images from two separate outputs into
a single image and prevents a visible separation line between the two images. Use
VCS to set or adjust the amount of horizontal and vertical overlap of the videowall
displays.
Each output canvas maintains its unique edge blend compensation settings with
discrete values for the horizontal and vertical edges. The settings are applicable to all
edges within the canvas.
Mullion compensation — Mullion is the area of frame border that exists around
each display. When designing the videowall, you must take this area into account
so that, when an image is spread across two or more displays, the image flow is
not distorted. The VCS enables you to adjust the space around each display to
compensate for the mullion (see figure 37 on the next page for an example).
