Configuring HDTV
Overscan Shift
The
Overscan
shift
setting
enables
you
to
pan
the
desktop,
when
needed,
to
access
any
display
elements
that
appear
off
‐
screen.
The
Overscan
shift
feature
works
by
tracking
the
position
of
the
mouse
cursor
and
slightly
shifting
the
display
when
the
cursor
starts
to
become
close
to
an
edge
of
the
desktop.
This
mode
looks
just
like
“native”
HDTV
formats
(720p,
1080i)
because
it
runs
at
the
full
HDTV
resolution,
which
causes
certain
elements
of
the
desktop,
such
as
the
Start
button
and
the
clock
on
the
Windows
taskbar,
to
not
be
visible
at
all
times.
But
as
the
mouse
cursor
gets
close
to
these
desktop
elements,
the
NVIDIA
driver
intelligently
shifts
the
desktop
a
little
in
order
to
move
those
elements
into
view.
explains
how
to
use
the
Overscan
shift
setting.
Native
In
the
third
technique,
native
mode,
no
overscan
compensation
is
done
in
order
to
give
the
user
a
true
cinematic
experience.
This
is
useful
when
you
do
not
want
any
pixel
compression
(squishing)
and
do
not
want
to
use
the
mouse
to
shift
the
desktop
image.
Notes on Startup Functionality with HDTV Connected
nView Single Display Mode
When
you
first
start
your
computer,
the
HDTV
display
may
have
color
distortion
and
may
not
fill
the
entire
screen
display.
This
is
because
when
you
first
start
your
computer
with
a
newly
‐
installed
driver,
the
TV
signal
format
defaults
to
NTSC.
nView Multi-Display Mode
When
two
displays
are
connected
to
your
computer,
you
will
notice
both
displays
are
mirrored
or
“cloned”
—
this
is
nView
Clone
mode.
