Preview Page
On the Preview page user can actually check what signal is being captured by the device.
This is a diagnostic function and when used it will stop the output of the captured signal to the
network interfaces.
Additionally when VGA signal is captured this page allows some adjustments that may be necessary if
e.g. signal on the output is not properly centered.
