BZBGEAR BG-UHD-88M PRODUCT MANUAL
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 TWO methods to do EDID Learning as below:
1. IR Remote Control: Please refer to the Operation Approach\ Method B: IR Remote
Control (Page 6.)
2. Software Control: Please refer to the Operation Approach\ Method C: Software
Control through RS-232 port (Page 9. 10)
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

BZBGEAR BG-UHD-88M PRODUCT MANUAL
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 Input-2
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.

Notice
1. If the DVI or HDMI device requires the EDID information, please use EDID
Reader/Writer to retrieve and provide DVI/HDMI EDID information.
2. All HDMI over Cat.X transmission distances are measured using Belden 1583A
CAT5e 125MHz LAN cable and ASTRODESIGN Video Signal Generator VG-859C &
VG-870B.
3. EIA/TIA-568-B termination (T568B) for LAN cables is recommended for better
performance.
4. To reduce the interference among the unshielded twisted pairs of wires in LAN
cable, one can use shielded LAN cables to improve EMI problems, which is worsen
in long transmission.
5. Because the quality of the LAN cables has the major effect on how long the
transmission limit can achieve and how good is the received picture quality, the
actual transmission range is subject to one’s choice of LAN cables. For desired
resolutions greater than 1080i or 1280x1024, a Cat-6 cable is recommended.
6. If your HDMI display has multiple HDMI inputs, it is found that the first HDMI input
[HDMI input #1] generally can produce better transmission performance among all
HDMI inputs.
7. Additional IR remote controls and IR blasters can be purchased as optional
accessories to control the HDMI sources located separately.
8. Solid cable is preferred.
