五、 Basic User Instructions

 After LVP615 starting, it enters the operation status of last shut-down including signal switching status, PIP/POP (or Text overlay) status and mosaic status. Among them, PIP/PBP( or text overlay) status and mosaic status can only realize relative functions and cannot do other operation. Other relative operations are available under signal switching status. We illustrate the common operations as below.


1、 Input signals selection

LVP615 supports two signal switching methods“One key switch”and“Pre.+Take switching”. The switching method can be set in user setup menu  “1.1Input video signal”. “One key switch” is default method. One key switch to new input signal through input signal selection buttons.;“Pre.+Take switch” only available for seamless switching. Press input buttons to preselect first. Then press Take button to switch from current input signal to preselected signal.

Input signal selection as follows:


Note:(1) YPbPr and V2 share the same port and signal. If need,configure the port to YPbPr in setup menu if need.

    (2) When EXT.input is VGA/DVI/HDMI,need manual switch DIAL switch to configure current input as composite video VGA or digital signal as DVI/HDMI.


1) One key switch

LCD screen display as below:


After select input signal, The first line on the LCD display the current input signal. Like:“ Input:HDMI ” 。The second line on the LCD display the signal status.If no active input, display” No input’. Meanwhile,the corresponding indicator flicker. Led screen is black. If active input, display input signal format Like:“ 1080p_60Hz ” 。


2) Pre.+Take switch 

LCD screen display as below:


Switch input method: press input button to preselect first, LCD screen displays the current input status and preselect input status.

Then press Take  button to switch current input to preselect input.

After the completion of switching, preselect signal become the current input signal.  The status of the preselect signal indicator:

when the signal is valid, the indicator flicker rapidly. when the signal is invalid, the indicator flicker slowly.


Note:Pre.+Take switch only available for seamless switching. LVP615 supports seamless switching between any two different input groups as follow. Same group does not support seamless switching. For example, current input is V1( V1 in group A). Then, preselect signal is only from B,C,D group. Signal group as follow. :











3) Switching time setting(C/ F)

In the signal switching status, press C/F button continually can change the current seamless switching transition time. LVP615 can achieve seamless switching between any two different input

groups of four input groups. Switching effect includes seamless switching (0s), Fade in/ Fade out (o.5s  1s  1.5s) and blend switching.

Seamless switching(Cut):On the LCD“Switch time” is 0s. LVP615 default switching is CUT. 

Fade in fade out(Fade):On the LCD“Switch time”is 0.5s1.0s or 1.5s. In this mode, different group signals support fade in fade out switching.

Blend switching:at this moment, on the LCD, current input is the main input. Select different group input signal as blend signal. The main input will overlay in the blend signal. Press blend signal or main signal button again. Then switch to selected signal. The whole process is fade in fade out effect.


Note:1. YPbPr does not support seamless switching, fade in fade out or blend switching. Switching between any signal and YPbPr signal will cause black led screen.

    2. Blend switching is only for signal switching. For other operations, press C/F to exit the blend switching state.

The definition of the LED screen is 3456×1920, we can divide it into the four small pieces of LED of 1728×960 pixels as shown in figure below, each piece of small LED screen is driven by a unit of LVP615. With total 4 sets of LVP615, the 3456×1920 pixels LED screen is able to display a full picture.














Below is the system topological diagram:



As above diagram shows, all input signals are connected to and switched by #0 LVP615. The 2 same DVI outputs of #0 LVP615 are connect to #1 LVP615 and #2 LVP615. Then DVI loop to #3 and #4.

After that, the output signal of #0 LVP615 is cropped and scale up in #1 LVP615, #2 LVP615, #3 LVP615 and #4 LVP615.

Finally the image that they output will be finally displayed as a whole picture on 4 pieces of LED screens.


The parameters of the 4 units of LVP615 are as below:

Setup options

Parameter setups of processor





E.1 LED total width


E.2 LED total height
