network port.
2. The screen layout is used to set the output screen, and supports up to 2 screens to display at
the same time.
3. Image effects are used to set image sharpness, saturation, color temperature, brightness and
other settings.
4. Image capture is used to capture the input source of the screen. You can set the screen and
coordinates captured after the input source is entered.
5. Save mode to save current parameters forming the template file, to facilitate subsequent
quick set.
6. Advanced settings are used to set input source resolution, restore factory settings, display
firmware version, and adjust VGA.

1. Output settings are used to set the coordinates and range of the network port:
Horizontal width: 256—the width of the LED screen;
Vertical height: 128—the height of the LED screen;
Horizontal start: setting parameter range = LED screen width-horizontal width;
Vertical start: setting parameter range = LED screen height-vertical height;
2. The connection relationship is set as the connection relationship processing of the
receiving card. Currently, only standard general mode is supported, and complex
connection relationships are not supported.

Horizontal start: horizontal start value range = input source width-
interception width
Vertical start: vertical start value range = input source width-interception
width.
Note: If the size of the captured screen is the same as the screen size, it will be
displayed point-to-point. If the size of the captured screen is different from the
screen size, it will be displayed by zooming.
