FAQs
1.
The quality of output video is not good enough, what can I do?
Please adjust the 8-level equalization at the bottom of the receiver units. The HDMI signal level varies from 0
(strongest) to 7 (weakest) for respective transmission length from longest possible range to short distance. It is
recommended to switch from 7 to 0 to find the optimal visual experience.
2.
Can I use any kind of LAN cable?
Please check the NOTICE section for more information about how to pick up a suitable cable.
3.
Can every TV work with the HDMI Matrix?
Basically, the answer is YES. But if your TV can not support 1080p, please refer the EDID LEARNING section to
learn EDID from your TV.
4.
What is EDID? Why do I need to learn EDID?
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.
5.
What should I do to learn EDID for the Matrix?
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 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 output-3 to all four HDMI inputs. For more information about EDID Learning, please refer to EDID
LEARNING section.
6.
My TV can support 1080p, but why there is no audio?
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.

7.
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?
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.
8.
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?
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.
