This section allows the user to fine-tune the settings of their screen from the G24H software.

The dropdown menu at the top of the section allows the user to select which screen to apply the settings to.

The read option reads the settings of the monitor/screen that are already in place and adjusts the values in the software, while the reset button will reset the settings to their default after they have been manually adjusted.

Video Wall

uses can set up the video wall layouts and signal configuration in this section.

**Video Wall Layout Setup

**

Users can set up the layout of the video wall in ‘VideoWall Setting’ by simply choosing how many rows and columns the video wall consists of. Total screens amount is up to 4 for one G24 HDMI video wall controller.

Creating the video wall

Click to select the screen, then drag & select the screens to splice, right- click, and click Screen splicing to form a video wall.

• Screen Splicing – This combines the selected screens into one and displays the selected input across all the splicing screens. For example, in the setup below 2×2, if all of them are spliced, then the input selected by the user will be displayed across all the 4 screens (Note: this is not the same as duplicating a single input on each output).
• Cancel Splicing – This will cancel the video wall and revert to the matrix switching mode.
• Screen – Cancel Splicing – Remove the single screen x from the video wall to allow the displaying another full frame image within the video wall configuration
• Input Select – Use the sub-menu to select the input to display on the  video wall or thesecondary input image shown in the above example.
• Output Select – The user can control which screen should be mapped to which output (only available in matrix mode)
• Output Type – Allows the user to adjust the type of the output (only in matrix mode)
• Output Format – Controls the resolution of the output (only available in matrix mode)
• 180° – Rotate the selected screen 180°.
• Test Pattern – To display Color Bar pattern on the screen

Bezel Correction

Users can set up the bezel correction for the video walls here to compensate the frame of the screens to make the whole video wall look like one large screen without any distortion. Users can either use pixels of the screen frame width or millimeter of the screen display area to set up the bezel correction here.

Save and Load Pre-set Layout

The user can save the video wall preset layouts and load it later via the Save Layout and Load Layout dropdown menu. Users can save up to 10 preset layouts here. Users also can recall these preset layouts via 3rd party controller though IP or RS232

Daisy Chain

Users can set up the daisy chain for multi units of G24 to achieve a big video wall (up to 16×16). Afour units daisy chain to form a 4×4 video wall will be used as an example below.

Set up the Devices’ ID and First Output Index

Users need to configure each unit with unique ID and output Index to enable control software to be able to recognize and control them in one system.

All units come with default Device ID:1 and First Output Index:1. Users only need to set up from 2nd G24.

| Device ID| First Output Index
---|---|---
G24 unit 1| 1| 1
G24 unit 2| 2| 5
G24 unit 3| 3| 9
G24 unit 4| 4| 13

First Output Index = 1 + (N-1) *4, N is the device ID

Noted: Any unit with Device ID being more than 1, G24 control software will not be able to connect it individually since the software will try to find device with ID 1 first. However, users are still able to change the Device ID and First Output Index without being connected properly.

Serial Ports Connection

Users are only able to use Serial port to connect and control the G24 units when they are working in daisy chain mode.

| RS232-Control Port| RS232 Port
---|---|---
G24 unit 1| To PC/Laptop| To RS232-Control port on unit2
G24 unit 2| To RS232 port on unit1| To RS232-Control port on unit3
G24 unit 3| To RS232 port on unit2| To RS232-Control port on unit4
G24 unit 4| To RS232 port on unit3|

Note: Please make sure the serial cable between G24 units is cross wired. Tx to RX, G to G and RX to TX

HDMI Cables Connections

Connect all the inputs with video sources and outputs with video wall screens using professional AV HDMI cables.

Setup in the Software

Run the G24 software and connect through RS232-control on device 1 and software will detect all 4 G24 and display 16 outputs in the software like below.
