4.1. Matrix Switch
Users can connect the G24 HDMI device to control PC and set up the device as matrix switcher in this
section.
4.1.1. Connect to the G24 HDMI via UART for RS232
Connect the G24 HDMI to the control PC with a serial cable (see 3.1 for cable wiring)
If the software was connected via UART
(RS232) last time, software will connect
to the G24 HDMI automatically via
RS232. If it was used at Network last time, a ‘Network Timeout’ error message will be shown on
screen and users need to set up as below for RS232 connection in the software
•Choose ‘UART’ instead of ‘Network’
•Select the COM port from the Port dropdown menu
•Press ‘Disconnected’ button to connect
The software will check all the parts of the device. A ‘Read data succeeded’ dialog box will be shown
on screen when finished.
4.1.2. Connect to the G24 HDMI via Network
The default IP address for G24 HDMI controller is 192.168.0.247, Users need to change the IP
address of the control PC to the same network segment as the G24 HDMI.
• Change the ‘Obtain an IP address automatically’ to ‘Use the following IP address’ to set up a
static IP address of TCP/IPv4 in Ethernet Properties
➢IP address: any address between 192.168.0.2 and 192.168.0.254 except the address which has
been taken by the G24 HDMI
➢Subnet mask: 255.255.255.0, Default Gateway: 192.168.0.1
Connect the G24 HDMI with a CAT cable to the control PC (cable included in the package)
If the software was connected via Network last time, software will connect to the G24 HDMI
automatically via network. If it was used at serial port last time, a ‘Please select COM port’ error
message will be shown on screen and users need to set up as below for Network connection in the
software
• Choose ‘Network’ instead of ‘UART’
• Press ‘Search Device’ button to find the G24 HDMI on the network
• Highlight the device Press ‘Disconnected’ button to connect

G24 HDMI User Guide
4.1.3. Matrix Switch Routing
Users can switch and assign different inputs to the selected outputs in the matrix. The name of the
output can also be changed by selecting the default name –HDMI 1 and replacing it with the chosen
name.
Users need to disable the video wall mode (Cancel the splicing) to enable the matrix switcher mode
•LOOP OUT: Choose input source for B/MAIN output port.
•AUDIO OUTPUT: Choose audio source for balanced audio output and Mini Toslink output
4.1.4. Allset, Recall, Save As and Reset
•The Allset dropdown menu helps the users select a single input to be displayed on all of the
screens (i.e. Allset HD A would display Input A on Output 1, Output 2, Output 3 and Output 4)
•Reset: Reset the unit to default factory configuration.
•EDID:
✓Read: read the EDID of the selected output
✓Save: save the displayed EDID after ‘Read’
✓Open: open an EDID from previous saved EDID
✓Write: write the current displayed EDID onto selected input
to customized input EDID

G24 HDMI User Guide
4.2. Signal setting
Signal Settings tab, users can use the ‘Read All’ function button to recognize the type and resolution
automatically. Additionally, you can also manually read one Input/output at a time –pressing the
Read button next to the selected input will only read that input alone.
I. Input Type Shows the input video sources type (HDMI or DVI)
II. Input Format Shows the resolution of the input video sources
III. Output Type
• UHD-HDMI Set the respective output signal to HDMI without HDCP.
• UHD-DVI Set the respective output signal to DVI, with no audio output
• UHD-HDMI 1.4 Set the respective output signal to HDMI with HDCP 1.4 compliance.
• UHD-HDMI 2.2 Set the respective output signal to HDMI with HDCP 2.2 compliance.
IV. Output Format
Users can manually change the output resolution here to match the requirement of the receiving
side (the default setting is 1920 x 1080@60, there are total 14 preset resolutions to choose from)

G24 HDMI User Guide
4.3. Fine Tune:PQ
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.
4.4. Video Wall
uses can set up the video wall layouts and signal configuration in this section
4.4.1. 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.

G24 HDMI User Guide
4.4.2. 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 2x2, 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 the
secondary 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
4.4.3. 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
4.4.4. 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

G24 HDMI User Guide
4.4.5. Daisy Chain
Users can set up the daisy chain for multi units of G24 to achieve a big video wall (up to 16x16). A
four units daisy chain to form a 4x4 video wall will be used as an example below.
I. 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.

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.
II. 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.
