Layout Modes
Layout Mode Introduction
The device supports 6 layout modes on the connected display, including
Original mode, Dual-view mode, PIP mode, H mode, Master mode, and Quad
mode. The processor supports seamless switching of input sources in the same
layout mode.
(1) Original mode: Only one original input signal source without image
processing is selected to be shown on the connected display. (See Figure
1: Original Mode).
(2) Dual-view mode: Two input signals are selected simultaneously to be
shown as two screens on the connected display. (See Figure 2: Dual-view
Mode.)
(3) PIP mode: Two input signals are selected simultaneously to be shown as
two screens on the connected display. The smaller screen covers on the
lower right corner above the larger one by default (See Figure 4: PIP
mode), and its location can be changed to bottom right (default), top right,
top left and bottom left positions through API commands. The size of the
smaller one is 1/16 of the larger one, and can be changed through API
Commands.
(4) H mode: The four input signals are selected simultaneously to be shown
as figure 4: H mode. The left and right screens can better display the
contents of the smart phone.
(5) Master mode: The four HDMI input sources is shown as 4 screens
simultaneously on the connected display (See Figure 5: Master Mode).
The master input can be selected from HDMI IN 1~4, and the slave
screens are in same size.
(6) Quad mode: The four HDMI input sources is shown as 4 screens in same
size simultaneously on the connected display (See Figure 6: QUAD mode).

Input Video and Audio Source Switching
After one layout mode is selected, users can circularly switch video and audio
sources in the layout mode through front panel or IR remote, or respectively
select input source through API commands (please refer to the separate
document “API Command Set_MV-4K-4X1” to get detailed information).
Circularly switching sequence is shown as the following function table. “1/2/3/4”
indicates HDMI IN 1/2/3/4, and “-” indicates invalid.

Screen Stretch Mode Switching
By default, the image on the display is shown in normal aspect ratio in order to
keep it undistorted. If users want to set one selected input’s image to stretch to
fill the entire screen, users can use the API command “SET VIDIN_STRETCH
prm prm1<CR><LF>” to change it.
For example, in Dual-View mode, by default, it is shown as figure 1, if users
want to set input 1 to stretch full screen, send command “SET
VIDIN_STRETCH 1 0 <CR><LF>”, and input 1’ s image will be shown as figure
2. More detail API information, please refer to the separate document “API
Command Set_ MV-4K-4X1”.
Control Operations
Figure 1 Figure 1

12
Users can control the device through front panel buttons, IR remote, and RS232
(API Commands).
Front Panel Control
Users can switch among the four inputs or input groups and six modes through
front panel buttons.
Operations are as follows:
1. Press “LAYOUT” button to select one layout mode to display. Press
continuously to switch layout modes as the following sequence: Original
→ Dual-view → PIP → H → Master → Quad → Original.
2. Press “SOURCE” button continuously to switch input source in current
selected layout mode. Switching sequence refers to the function table in
“Input Video and Audio Source Switching” section.
3. Press “INPUT SELECT BUTTON” to enter Original mode, and select the
1/2/3/4 button to switch to corresponding input as source.
4. Press “AUDIO” button to switch audio channel in some layout modes.
Switching sequence refers to the function table in “Input Video and Audio
Source Switching” section.
IR Remote Control
Users can switch among the four inputs and six modes for
the output display by pointing the provided IR remote directly
to the IR window on front panel or point to the IR receiver
head connected to the rear panel.
Note: Switching sequence of video and audio in different
layout mode refers to the function table in “Input Video and
Audio Source Switching” section.
Button Function
Press the button to mute/unmute HDMI output of the device.

13
Button Function
The button can mute/unmute the HDMI output and send CEC

Press the button to switch output resolution between 4K@60Hz
and 1080P@60Hz.
Press to switch to original mode, and select HDMI IN 1/2/3/4 as
signal source.
Press the button to switch audio channel in current layout mode.
Press the button to mute the audio in current layout mode. Press
again to exit the mode and return to the audio channel selected
before the mute operation.
Press the button to switch to Original mode and press
continuously to switch among HDMI IN 1~4 sources.
Press the button to switch to Dual-view mode, and press again

Press this button continuously to cycle 1→2→3→4→1 to the
Master screen.
The button is used to switch between the two sets of IR system
codes (“00” and “4E”) of the provided IR remote. It is used to
solve the problem of IR code conflict between IR remote control
and other IR devices.

RS232 Control
Advanced users may need to control the device through RS232 serial
communication. Connect a control PC or control system to the RS232 port of
the processor. API command for RS232 control is available in the separate
document “API Command Set_MV-4K-4X1”. A professional RS232 serial
interface software (e.g., Serial Assist) may be needed as well.
Before executing the API command through RS232 serial connection, please
ensure RS232 interface of the device and the control PC are configured
correctly.
