The BG-UHD-44M HDMI 2.0a Matrix provides the most flexible and cost-effective solution in the
market to route high definition video sources plus multi-channel (up to 7.1-channel) digital audio
from any of the four HDMI sources to the remote displays at the same time. BG-UHD-44M18G supports
HDR and the true 4K2K video! Besides, BG-UHD-44M18G supports auto downscale from 4K2K to
1080P. With this benefit function, the matrix device compatibility will be better.

With the upmost HDR/4K2K@60 4:4:4 8bits and high definition audio support, BG-UHD-44M18G is
well suited for use in home theater, conference room presentation systems, or other similar
setting or application.

EDID LEARNING

The EDID learning function is only necessary whenever you encounter any display on the HDMI
output port that cannot play audio and video properly. Because the HDMI source devices and displays
may have various level of capability in playing audio and video, the general principle is that the source
device will output the lowest standards in audio format and video resolutions to be commonly acceptable
among all HDMI displays. In this case, a 720p stereo HDMI signal output would be probably the safest
choice. Nevertheless, the user can force the matrix to learn the EDID of the lowest capable HDMI display
among others to make sure all displays are capable to play the HDMI signals normally.

There are THREE methods to do EDID Learning as below,

1. IR Remote Control: Please refer to the Operation Approach\Method B: IR Remote Control

2. Software Control: Please refer to the Operation Approach\Method C: Software Control through RS-

232 port

3. Web Interface Control: Please refer to the Operation Approach\Method D: Web Interface Control

There are seventeen embedded default EDID as below,

1. Full-HD(1080p@60)-24bit 2D & 2ch

2. Full-HD(1080p@60)-24bit 2D & 7.1ch

3. Full-HD(1080p@60)-24bit 3D & 2ch

4. Full-HD(1080p@60)-24bit 3D & 7.1ch

5. HD(1080i@60)(720p@60)-24bit 2D & 2ch

6. HD(1080i@60)(720p@60)-24bit 2D & 7.1ch

7. Full-HD(1080p@60)-36bit 2D & 2ch

8. Full-HD(1080p@60)-36bit 2D & 7.1ch

9. Full-HD(1080p@60)-24bit 2D & 2ch & Dolby 5.1ch

FAQ

Q Can every TV work with the HDMI matrix?
A Basically, the answer is YES. But if your TV cannot support 1080p, please refer the EDID LEARNING

section to learn EDID from your TV.

Q What is EDID? Why do I need to learn EDID?
A EDID contains the whole information of the display such as the resolution and audio setting which this

display can support. Therefore, based on the EDID information, media player will pick up the most suitable
resolution and audio setting to the display. In order to faithfully transmit the EDID information from display
to the media player, learning EDID from display to this device is necessary.

Q What should I do to learn EDID for the matrix?
A Due to the limitation of HDMI, the source device can only output one format of video and audio. In

other words, the source device cannot output 720p and 1080p video at the same time, or output stereo
and surround sound at the same time. Therefore, you may need to manually setup each HDMI input for
desirable audio/video output format. The mechanism of EDID Learning is to pick up the HDMI display with
the lowest capability among the ones you would use for this input source. For example, if user would like
to play the Input-2 upon output-2, output-3 and output-4, and only output-3 cannot support 1080p
[support up to 720p only], please learn the EDID from the display connected to the output-3 at the Input­2 port. Of course, if outpt-3 would get the HDMI signals from every HDMI input, please learn EDID
information from output3 to all four HDMI inputs. For more information about EDID Learning, please refer
to EDID LEARNING section.

Q My TV can support 1080p, but why there is no audio?
A The factory default EDID of this device is 1080p &2ch audio. However, there would be a problem after

you change to use 1080p & 7.1ch if the TV cannot support 7.1ch audio. Please use the default EDID,1080p
&2ch audio.

Q When I set an audio amplifier (AV receiver) between TV and the matrix to extract 7.1ch audio, but
why there is still no audio?

A Basically, the default EDID of the chosen input can support 7.1ch audio, but the problem is that the

EDID of the amplifier still cannot match the default setting. Therefore, the best method is to learn EDID
from the amplifier directly. Please refer to EDID LEARNING section and follow the steps to learn the EDID.
When learning EDID from the amplifier, user just needs to connect the matrix and amplifier. Please don't

connect HDMI cable between amplifier and TV when the EDID learning is proceeding.

Q When I play the same content upon multi-displays, why only the TV equipped with amplifier can
have 7.1ch audio, and the others don't have 7.1ch audio even no stereo?

A Due to the limitation of HDMI, the source only can choose one video and one audio format to play,
which can be either 1080p and 7.1ch or 1080p and stereo audio. It means when the user sets the matrix
at 1080p and 7.1ch, the source will only play the content under this format. Therefore if the TV cannot
decode 7.1ch audio, there is definitely no audio.
