GENERAL
MultiSync,
The
Inteligent
Monitor,
is
a
high
resolution
color
monitor
that
automatically
adjusts
to
graphics
board
scanning
frequencies
from
15.5
KHz
to
35
KHz.
MultiSync
gives
IBM
PC,
PC/XT,
and
PC/AT
users
crisp
text
and
vivid
color
graphics
displays
when
used
with
any
of
the
three
IBM
graphics
adapters
(the
CGA,
EGA
or
PGA)
MultiSync
can
also
be
used
with
other
IBM
compatible
graphics
adapters
to
provide
ІВМ
users
with
the
widest
range
of
color
monitor
compatibility
and
capability
available
in
the
market
place.
FEATURES
е
MultiSync
automatically
scans
all
frequencies
between
15.5
KHz
and
35
KHz.
@
MultiSync
is
compatible
with
the
IBM
PC,
PC/XT,
PC/AT
and
look-alikes.
®
MultiSync
is
compatible

IBM
Professional
Graphics
Adapter,
the
IBM
Enhanced
Graphics
Adapter,
the
IBM
Color
Graphics
Adapter
and
other
IBM
compatible
graphics
adapters.
ө
MultiSync's
wide
compatibility
makes
it
possible
to
upgrade
boards
or
software
without
purchasing
a
new
monitor.
@
MultiSync
has
a
maximum
horizontal
resolution
of
800
dots
and
a
maximum
vertical
resolu-
tion
of
560
lines
for
superior
clarity
of
display.
ө
MultiSync
offers
both
TTL
and
АМАГОС
signal
inputs,
and
in
the
ANALOG
mode
can
display
an
unlimited
palette
of
colors
depending
on
the
graphics
board
and
software
being
used.
ө
MultiSync
features
a
TEXT
SWITCH
with
a
choice
of
seven
colors
(red,
blue,
green,
cyan,
yellow,
