Picture Setup Menu
The Picture Setup menu items are described below.
Thumbnail
A thumbnail is approximately 1/16 of the full screen display or 1/16 of the pane. It is
used to show the picture that is being measured in the pane or display. Up to four
thumbnails can be shown simultaneously. Each thumbnail can be for the same or
different input. When in quad mode (not full screen), the thumbnail will not be
displayed if one of the four panes has picture selected.
The thumbnail picture is shown in one corner of each Upper Left, Upper Right, Lower

display containing a thumbnail in the lower-right corner of the lower right pane is
shown in Figure 4-2.
