The main menu is divided into 5 sections, which are Output, Input, Preset, Config, and Info. Each section has multiple sub-menus that need to be set up for the best performance.

Main >
1 / 5	1 / 5
Output >	Output 1 >
Input >	Output 2 >
Preset >	Output 3 >
Config >	Output 4 >
Info >	All >

Output

There are 5 sub-menus in the Output interface: output 1\~4 and All, which are used for individual or all output settings. Each channel contains 3 function items, which are video, audio, and power.

Main > Output >
1 / 5	1 / 3
Output 1 >	Video >
Output 2 >	Audio >
Output 3 >	Power >
Output 4 >
All >

Choose a desired output before setting video or audio parameters.

There are 9 options in video: Source, Onoff, Pattern, Format, Genlock, Mirror, Coord, PIP, and Image. There are 4 options in Audio: HDMI onoff, HDMI SRC, DEC onoff, and DEC SRC.

Main > Output > Output 1 >
1 / 3	1 / 10
Video >	Source >
Audio >	Onoff >
Power >	Pattern >
	Format >
	Genlock >

1) Source

Any output can be switched to any input or all outputs can be switched to the same input; Default setting is PTP (Point to Point)

Main > Output > Output 1 > Video >
1 / 9	4 / 4
Source >	Input 1
Onoff >	Input 2
Pattern >	Input 3
Format >	Input 4 @
Genlock >

2) Onoff

Turn the video stream on or off for one or all of the outputs. The video streams are turned on by default.

3) Pattern

Built-in images can be shown on a display(s) by using the Pattern option which can be used for signal testing or video alignment.

For example: Using the Cross or Cross1 images in 4x4 Video Wall mode to test whether each display is formatted and mounted correctly.

4) Format

The Format function can set and force the output resolution format but it does not provide an upscale image quality.

Example:

The input is 1080P@60Hz and the output is set to 4K60Hz. Although the TV is displayed in 4K@60Hz the image will still be in 1080P@60Hz.

NOTE:Selecting the input mode will enable the following input resolution but switching with the matrix will not be seamless unless the resolution from the source is in the same format and without HDR. There will be a system check time for 15 seconds. The setting will return to the original resolution if the display does not support the selected resolution.

5) Genlock

Genlock is a common technique where the video output of one source is used to synchronize other picture sources together. Default is to Off. Output 1 cannot be selected as it is the reference. Only Output 2, Output 3, and Output 4 can be enabled. Switching the output resolution will affect other output images. (The image may be black for a while and the resolution will not be able to be changed.)

Main > Output > All > Video >

7) Coord

Coord is used to fine tune the parameters of an image in multiview and video wall modes. There are 3 types including Crop, Zoom, and Gap.

Crop trims an image, Zoom will magnify the image, and Gap will compensate for the bezel on the display.

There are a total of 10 coordinate parameters which can be changed: CROPX0, CROPY0, CROPX1, CROPY1, ZOOMX0, ZOOMY0, ZOOMX1, ZOOMY1, GapX, and GapY.

Adjusting these parameters will have effects in multiview and video wall modes.

The default starting point of Crop : CROPX0 = 0, CROPY0 = 0.

The default end point of Crop: CROPX1 = 6000, CROPY1 = 6000.

The default start point of Zoom: ZoomX0 = 0, ZoomY0 = 0

The default end point of Zoom: ZoomX1 = 6000, ZoomY1 = 6000

The default start point of GapX=0, GapY=0

8) PIP

PIP is mainly used for the layer priority. By default, each output has 4 layers. It can change the sequence of the layers in multiview mode. Each layer can choose an output. You can turn this function on or off in Status.

Alpha will adjust the transparency between the layers.

NOTE: One layer can select only one output and it cannot select it repeatedly, otherwise it will not take effect.

9) Image

Image is used to set the parameters of the output image. There are 4 parameters: Brightness, Contrast, Saturation, and Hue. Parameters range from 0 to 100 and they are set to 50 by default.

Audio

There are 4 options in Audio: HDMI Onoff, HDMI SRC, DEC Onoff, DECSRC. This unit can switch audio independently, turn off HDMI audio output, extract audio as well as switch extracted audio to another source.

1) HDMIOnoff

HDMI Onoff can turn HDMI audio on or off. Video will be displayed on TV without audio when turning off the audio.

2) HDMISRC

HDMI SRC enables switching to different input signal sources. It supports switching to analog audio in 1\~4 and HDMI input 1\~4.

AutoHDMI(Default) the audio is from the corresponding input.

Power

Power will turn on or off the HDMI output of 5V. This is different from “Onoff” as there is a blue screen displayed on a TV while selecting “off” in “Onoff”. Image will completely turn off after selecting “Off” in “Power”. It is on by default.

Main menu including 5 Modes: Output, Input, Preset, Config, Info

Input

There are three options in the Input interface which are Video, Audio, and EDID. Video is used to provide the switch channel and built-in Pattern switch. Audio is used to set the delay to sync embedded/extracted audio with a video stream. EDID supports built-in, copy, user, and temp.

1) Video

Video Onoff can turn the input channel on or off. All of the outputs corresponding to the input will have no image or audio when this input is set to "Off". Pattern provides a built-in pattern which can be selected to replace the input source image.

2)Audio

Audio delay setting range 0\~50(ms) and auto, the default is auto. This setting is used to help embedded or extracted audio sync better with the video stream.

3)EDID

There are 4 EDID options including built-in EDID, User EDID, Copy HDMI EDID, and temp. Each input EDID can be set individually. The default setting is default1.
