LCD shows the current selected input signal source on the first row after selecting the input
signal, such as: HDMI. LCD shows the status of the current selected input signal source on the
second row, if there is no input signal source, it will show “No effective inputs”, and the indicator
flash at the same time. If there do exist an effective input signal, then it will show the input format,
such as：“ 1080p_60Hz ” .

Signal switching method：firstly press the input buttons to preselect the input signal, and the
LCD screen will show you the current input signal and the preselected input signal, then switch the
input signal between them by pressing Take button, after switching, the preselected input signal
becomes the current input signal. If the indicator flashs quickly, it means there exist a input signal,
otherwise, there is no input signal.
Attention ：Pre.+Take switch is a seamless switching, we can select one input signal among
these 4 groups of input signals unless they belong to the same group. For example: if the current
input signal is V1（V1 belongs to Group A）, you can only choose one input signal from Group B,
Group C or Group D, the groups are as follows:
A
B
C
D
V1、V2
VGA
DVI1、DVI2、HDMI1、
HDMI2
EXT.
3)Switching time selection
We can realize seamless switching among the 4 groups of input signals unless they belong to
the same group. The switching effect includes 0 second fast seamless switching, 0.5 second 、1
second、1.5 second fade in and fade out switching, we can enter Menu 3.2 to select the option to
choose switching time.
Cut：switching time: 0 second, it is the default switching effect of LVP919。
Fade：switching time: 0.5 second、 1.0 second or 1.5 second. you can realize fade in and fade
out switching among these 4 groups of input signals.

2)VGA input auto adjustment ( Auto )
When LVP919 is under one-key directly switching mode, the current input source is a valid VGA
input signal, press Auto to enable the LVP919 to automatically adjust the sampling parameters of
the VGA input signal, making the VGA image clear and complete.
This operation is usually performed only when a new VGA source is connected. The
auto-adjustment time changes depending on the condition of the input signal source, and usually
