Q1:
The
display
on
the
secondary
monitor
is
blank.

If

monitor
power
LED

green
(in
most

wait
a
moment
for
the

sometimes
it
takes
time
for
the
secondary
monitor
to
show
the

You

also
reboot
your

to
try
again.
Also
make
sure
the
computer
is
not
in
standby
or
hibernation
mode,
which
will
lead
the
secondary
monitor
to
be
blank.
If
the
monitor
power
LED
is
red
(in

made.
If

exists,
uninstall
the

unplug
the
adapter
and
reinstall
the
driver
to
try
again.
Q2:
The
secondary
monitor
is
flickering.
A:
This
is
usually

refresh
rate.
To
solve
this

This

rate
of
the
secondary
monitor.
•
In

mode,
increase
the
refresh
rate
of
the
secondary
monitor.
Q3:

I
play
MPEG
file
by
Windows
Media
Player
on
the
extended
monitor,
how
come
the
display
becomes
abnormal
when
I
switch
it
to
full
screen
mode?
A:
If
your

is
Windows
®
XP
SP1,
we
suggest
you
upgrade
it
to
SP2
to
solve
this
problem.
