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

The Quantum Ultra output card can support rotation of two 1920x1080 outputs at 60 Hz
or one 3840x2160 output at 30 Hz. When rotation is enabled, only outputs 2 and 4
are addressable if the resolution pixel clock is less than 165 MHz and only output 4 is
addressable if the output resolution is greater than 165 MHz (see the following examples).
Maximum rotated output signals for each output card
The following examples show the number of rotated output signals that are supported on
each 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)
Figure 35.
NOTE: Column and quad outputs cannot be rotated.

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 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
Quantum Ultra Videowall Processing System • Installation and Configuration
figure 36 on the next page for an example).
