Introduction
The BG-UHD-DA2X8 is an HDMI 2.0 2x8 splitter that can distribute either of the two HDMI
inputs to eight outputs. The splitter supports HDMI video resolutions up to 4K@60Hz 4:4:4,
1080p 3D, and multichannel audio formats. In addition to passing EDID information from the
display, there are multiple built-in EDID settings that can be selected by the 4-pin DIP
switches on the rear panel.
The splitter can extract HDMI digital audio to stereo analog L/R and Toslink S/PDIF audio
outputs to provide audio sources for existing audio systems. Built-in CEC technology is able
to turn on/off displays and adjust volume using the control buttons on the front panel if the
device is supported.
Features
● HDMI 2.0 and video resolutions up to 4K@60Hz 4:4:4.
● HDMI inputs HDCP 2.2 and outputs HDCP 1.4 compliant.
● Video resolution down-scaling: the 4K input can be automatically downscaled to
1080p to support legacy displays.
● 18Gbps high bandwidth.
● RCA (L/R) jack and Toslink connector for audio extraction.
● Advanced EDID management: multiple preset and user defined.
● Built-in equalizer for signal enhancement to avoid signal attenuation in transmission.
● CEC control to turn on/off displays and adjust volume for supported devices.
● Provides LEDs to indicate the current operating status and to assist troubleshooting
and installation.
● Firmware upgradable via the Micro-USB port.
Packing List

BZBGEAR BG-UHD-DA2X8 PRODUCT MANUAL
EDID Management
The Extended Display Identification Data (EDID) is used by the source device to match its
video resolution with the connected display. By default, the source device obtains its EDID
from the first connected display. Since displays with different capabilities can be connected
to the splitter, the 3-pin DIP switch on the front panel and the 4-pin DIP switch on the rear
panel can be used in combination to set the EDID to a fixed value to ensure compatibility of
video resolutions.
Switch Status
Description
L.RES
The splitter reads all EDID information from all connected displays,
and choose the one with lowest resolution passing to the source.
PRESET
In this mode, the 4-pin DIP switch on the rear panel can be used to
select predefined EDID and customize a specific EDID as needed.
H.RES
The splitter reads all EDID information from all connected displays
and chooses the one with the highest resolution passing to the
source.
● Predefined EDID setting
When the 3-pin DIP switch on the front panel is in PRESET mode, the 4-pin DIP switch on
the rear panel can be used to set the EDID to a built-in fixed value. Use the following table to
determine the settings for the 4-pin DIP switch for specific
video resolution and audio capabilities.
When in the lower position, the switch represents “0”, while in
the up position, it represents “1”.

BZBGEAR BG-UHD-DA2X8 PRODUCT MANUAL
● User defined EDID setting
If not using the built-in EDID, specific EDID settings can be customized by following the
operation process below.
1. Rename the user defined EDID according to the following format.
EC_xx_xxxx_xxx.bin
● EC: Represents EDID.
● xx: Represents EDID ID. It is “15”.
● xxxx: Represents the video parameter.
● xxx: Represents the audio format.
Example: EC_11_720P_LPCM.bin
2. Power on the splitter and connect it to the PC with a USB cable. The PC will
automatically detect a U-disk named “BOOTDISK”.
3. Double-click to open the U-disk, a file named of “READY.TXT” will be showed.
4. Copy the user defined EDID (ex EC_11_720P_LPCM.bin) to the “BOOTDISK” U-disk.
5. Reopen the U-disk to check the filename “READY.TXT” whether automatically
becomes “SUCCESS.TXT”, if yes, the user defined EDID was imported into the
splitter and saved as its corresponding EDID ID successfully.
6. Remove the USB cable, and then reboot the splitter.
7. The new EDID now can be invoked via the 4-pin DIP switch directly. The EDID ID and
its corresponding switch status is shown in the below list.
Video Resolution Downscaling
The BG-UHD-DA2X8 supports video resolution downscaling. This means a 4K input can be
automatically degraded to 1080P output for compatibility with 1080P displays. Compatibility
is shown in the chart below:
