3-2 Button instructions (operation mode):
There are 33 buttons and one knob on the frontal panel of LVP40X, all
these buttons will be operable after start. they have the following
functions as described below:
1) Select input video source
2-channel PAL/NTSC composite video input
1-channel computer analog signal input
1-channel DisplayPort digital HD signal input
1-channel computer digital signal input
1-channel HDMI digital HD signal input
1-channel digital video signal input ( SD/HD)
After user has selected input signal, the current input signal source
that you selected, e.g.: INPUT=HDMI will appear in the LCD. In the
meantime, the indicator above the corresponding button will
indicate the status of current input signal source. If there is no valid
signal input, the indicator will blink and dark screen appears; if the
signal is valid, the indicator will illuminate normally.
2) VGA input auto adjustment (Auto)
When the current VGA input source of LVP40X is a valid signal,
press this button, LVP40X will automatically adjust the sampling
parameters of the VGA signals, so as to make VGA picture clean
and complete.

In general, this operation is made only when new VGA signal
source is to be connected in. Sometimes user need repetitively do
such adjustment till VGA picture looks clean, complete and stable.
3) Select output brightness
Decrease output image brightness of LVP40X, the
lowest brightness is 0.
Increase output image brightness of LVP40X, the
highest brightness is 32.
LVP40X supports 8 levels of output Brightness, “0” represents the
lowest brightness, and 32 represents the highest brightness. To
ensure full gray level of output image, normally the output
brightness is set as 32!
4) Information display (Info)
This button can be operated to display the following two status
information:
Current settings of LVP40X: Press
“
Info” button to display
current settings and information of LVP40X. There are total 29
items of information. Press “Info” button again before the
information disappears in LCD, the next entry of information will
appear in LCD.
Status of current input signal source: press current input
selection button, then Press“Info” immediately, the input signal
source selected, e.g.: “In: HDMI” , will appear in line 1 in LCD, and
the status of current input signal source will appear in line 2 in LCD.
If no valid signal is input, “No Input” will appear in LCD; if the
signal is valid, its input signal format such as “1080p_60Hz” will
appear in LCD.
5) Information display of DVI output ports (Out1,Out2,Out3,Out4
,
Out5,Out6,Out7,Out8,Out9,Out10,Out11,Out12,)

Figure 3-2
While in operation mode, press “Out1”, the input and output
parameters of current DVI Out1 will appear in LCD at the location
as shown in above figure.
Press “Out2”, the input and output parameters of current DVI Out2
will appear in LCD at the location as shown in above figure.
Press “Out3”, the input and output parameters of current DVI Out3
will appear in LCD at the location as shown in above figure.
Press “Out4”, the input and output parameters of current DVI Out4
will appear in LCD at the location as shown in above figure.
Press “Out5”, the input and output parameters of current DVI Out5
will appear in LCD at the location as shown in above figure.
Press “Out6”, the input and output parameters of current DVI Out6
will appear in LCD at the location as shown in above figure.
Press “Out7”, the input and output parameters of current DVI Out7
will appear in LCD at the location as shown in above figure.
Press “Out8”, the input and output parameters of current DVI Out8
will appear in LCD at the location as shown in above figure.
Press “Out9”, the input and output parameters of current DVI Out9
will appear in LCD at the location as shown in above figure.

Out11 will appear in LCD at the location as shown in above figure.

Press “Out12”, the input and output parameters of current DVI
Out12 will appear in LCD at the location as shown in above figure.
6) Select Cut / Fade mode
LVP40X can realize seamless switching effect (Cut) or fading in/out
switching effect (Fade) between any two signals from different
groups as listed below. But if the signals come from the same group,
LVP40X can only realize freezing seamless switching effect.
Cut: the moment the LED indicator above the button is off. In this
mode, user can transiently shift picture seamlessly without flickering,
tremble, stasis, delay, black screen occurring. Cut is the default
special effect switching mode of LVP40X.
Fade (Fading-in/out mode): the moment the LED indicator above
the button is on. In this mode, user can shift the picture coming from
different input signal groups in fading-in/out mode without flickering,
tremble, stasis, delay, black screen occurring.
Freezing seamless switching: the pictures coming from the same
group can only be shifted in freezing seamless switching mode.
That is to say, after you select another input signal which belongs to
the same group with that of currently displayed signal, current
signal will first be frozen, then be superseded transiently by the
signal you selected.
PIP mode of LVP40X allows user to insert a PIP window in current
picture, and the size and location of the PIP window can be
changed freely. The signals to be displayed in PIP window can
either be signals coming from other groups or be current signal itself.
Here we call current picture “background”, and call the picture to be
overlaid “PIP”.
