From the Avant
Example 1 shows a single screen with 3 Avant windows, shown in yellow.
The software analyses the position and size of the Avant Window and
allocates each window to an overlay. Avant supports up to 4 overlays but
there can be only one overlay covering any particular screen.
In this example a single overlay would be generated that bounds the 3
Avant windows. The overlay size and position is shown as a broken line
(-----). In the following examples any window shown in YELLOW
indicates GOOD QUALITY.
Windows shown in Red indicates POOR QUALITY. The trick for best
quality is to position the windows such that the bounding overlay is as
small as possible.
Note: You cannot display 2 or more overlays on the same screen
and there is a maximum of 4 overlay’s available.

Example 2
In this example a 4th Avant window is now opened on a 2 x 2 wall. The
new window is large and touches the same screen as the 3 small
windows. This creates poor quality overlays.
Avant can only use one overlay to produce this layout because 2 overlays
cannot cover the same screen. The overlay has to bound all 4 windows
and then be up-scaled to cover the screen area. The video quality for the
large window shown in yellow will be good. The 3 smaller windows have
