Note: Gigabit network connection provides the best transfer rates and the best quality
video output. Slower connections may cause dropped frames, and should be considered
unsuitable, especially for HD sessions. In extreme cases, where network capability is low
or unreliable because of other traffic, iVGA may still be useful for static displays.

The video source menu governs the imagery iVGA
transmits or captures. The menu lists a number of
important options (Figure 272).
 At the top, you will see all monitors connected to the
system iVGA PRO is running on named. Selecting a
monitor by name assigns its entire display as the
current iVGA source.
 Just beneath the list of monitors is the Region option. This refers to the portion
of the screen that is inside a rectangular marquee that is shown when Region
source mode is newly selected.
o Drag the cross-hair icon in the center of
the marquee to relocate it on the screen
or to a different monitor.
o Drag the mouse on any border of the
marquee to scale it up or down. By
default, scaling is constrained to retain a
16:9 marquee aspect. Hold down Ctrl
when dragging to release the aspect lock. To restore the marquee’s
standard widescreen aspect, simply drag the border again without the
Ctrl key depressed.
o The next Video Source option shown
in the menu is Window. This is a
particularly useful option, as it
allows you to ‘snap’ iVGA to a
specific application window (or child window).
