Using nView Multi-Display Settings
Note:
This
also
results
in
nView
Span
modes
being
slightly
faster
than
Dualview
mode
because
Windows
only
has
to
manage
one
display
instead
of
two.
• Under
nView
Span
modes,
Windows
“stretches”
the
background
wallpaper
out
to
cover
your
large
“logical”
display
and
it
stretches
the
taskbar
out
to
fill
your
large
“logical”
display,
as
shown
in
If
you
maximize
an
application,
the
application
will
be
maximized
to
fill
the
large
“logical”
display
screen
–
i.e.,
both
displays.
• Under
Windows
XP/2000,
you
can
run
nView
Span
modes
with
more
than
two
displays.
For
example,
if
you
are
using
a
Quadro
NVS
‐
based
graphics
card
to
which
you
have
four
displays
connected,
you
can
have
two
sets
of
two
spanned
displays.
If
you
are
using
a
Quadro
NVS
‐
based
graphics
card,
refer
to
the
document
titled
“
NVIDIA
ForceWare
Driver
for
Windows
Using
nView
MultiView
Modes
with
NVIDIA
Quadro
NVS
‐
based
Graphics
Cards
”
Using Horizontal & Vertical Span Modes
Note:
Span
modes
do
not
work
if
you
have
only
one
display
attached.
In
Span
mode,
the
Windows
desktop
area
is
spread
across
both
displays.
This
mode
can
be
set
for
multiple
categories
of
displays,
although
display
limitations
may
override
the
capabilities
of
your
NVIDIA
multi
‐
display
graphics
card.
For
example,
if
the
second
display
is
an
NTSC
TV
display,
depending
on
the
TV
encoder
on
the
graphics
card,
the
resolution
may
not
be
set
above
800
x
600
and
the
refresh
rate
cannot
be
set
above
60
Hz.
However,
the
computer’s
analog
display
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
9
x
and
Windows
NT
4.0/
Windows
2000,
the
latter
does
not
currently
offer
true
multi
‐
display
support
for
Span
modes
using
one
NVIDIA
multi
‐
display
graphics
card
5
.
As
a
result,
size
of
the
actual
desktop
is
limited
to
twice
the
smaller
size
of
the
two
displays.
Note:
The
desktop
can
be
extended
either
horizontally
(
)
or
vertically
(

If two graphics cards are installed, the Windows 2000 operating system does detect two devices.
