1. Background
The
traditional
monitors
have
the
function of
electricity-savin
g
d
ormanc
y
.
Bu
t
t
he
interval
of
dormanc
y

s
d
if
ficult
to
decide.
If
the
interval
is
long,
the
purpose
of
saving
electricity
can
not
be
achieved
.
W
hile
if
th
e
i
nterva
l
i

s

,
y
our computer
and
LCD
monitor
will
be
dormant
often.
Whe

he

.
The
frequent
turning-on
and
turning-o
ff
of
lights
will
result
in
th
e
l
ightness
being
uneven

, shortening
the
life
of
the
lights.
2. Our
solution
to
the
dilemm
a
–
M
onitor
the
Life-Extension
function
In
view
of
that,
we
have
designed
the
function of Monitor
Life-Extension.
Once
yo
u
s
elec
t
t
he
option
of
“Advanced
Power
Saving
Mode”
in
the
OSD
menu,
and
then
you

,
bu
t
e
xten
d
t
he
life
of
th
e
l
ights.
3.Working
principle
of
the
Monitor
Life-Extension
function
T
o
minimize
the
impact
of
frequent
turn-on
and
turn-of

4. The
side
effect
of
the
Monitor
Life-Extension
function
(why
not
preset

as
default?)
