Primary Span extends ZoomText's magnified view across the primary and secondary monitors, doubling the amount of information that can be seen at any time. With twice as much information in view you can work with greater speed and comfort than is possible when using a single monitor.

Primary Clone displays the same magnified view on your primary and secondary monitors. This mode is useful when two or more users need to see the same magnified view, but are not seated so that they can share a single monitor.

Primary with 1x displays a magnified view on your primary monitor and an unmagnified view on your secondary monitor. This mode is useful when a low-vision user and normal-sighted user are working together on the same system. The low-vision user can zoom-in to the desired level (on the primary monitor) while the normal-sighted user sees the unmagnified view on the secondary monitor.
