The Zoom icon controls the zoom factor for the remote view window.
Settings are as follows:
Setting Description
100% Sizes and displays the remote view window at 100%.
75% Sizes and displays the remote view window at 75%.
50% Sizes and displays the remote view window at 50%.
25% Sizes and displays the remote view window at 25%.
1:1 Sizes and displays the remote view window at 100%. The difference
between this setting and the 100% setting is that when the remote
view window is resized its contents don’t resize – they remain at the
size they were. To see any objects that are outside of the viewing
area move the mouse to the window edge, to have the screen scroll.
