Q: Can every TV work with the HDMI matrix?
A:
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.
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, the 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 maunally 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 source. For example, if you 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 output-3 would get to 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.
Q: My TV can support 1080p, why is there 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: I set an audio amplifier (AV receiver) between the TV and the matrix to extract 7.1ch audio, why is
there
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 matrixand 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, only the TV equipped with the amplifier has
7.1ch audio. Why don’t the others have 7.1ch audio or at least 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 will be no audio.
