600 and the refresh rate cannot be set above 60 Hz. However, the PC monitor in
such a configuration may have its refresh rate and resolution set much higher.
The desktop may be “stretched” horizontally or “stacked” vertically, depending
on user needs.
Due to operating system differences between Windows 9x and Windows NT

result, the size of the actual desktop is limited to twice the smaller size of the
two displays.
Note: The desktop can be extended either horizontally (Figure 6.33 through
Figure 6.37) or vertically (Figure 6.40 and Figure 6.43).
To access the TwinView Span modes, follow these steps:

you can drag your active windows, images, or icons horizontally or vertically
to move them to the secondary display.
