press this button, LVP40X will automatically adjust the sampling
parameters of the VGA signals, so as to make VGA picture clean
and complete.

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.
A
B
C
D
V1, V2
VGA
DP, DVI, HDMI
SDI
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signal will first be frozen, then be superseded transiently by the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.
7) PIP / POP
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”.
