11. FAQ
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, 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 au-
dio. 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 .
Thefactory default EDID of this device is 1080p &2ch audio.However, there would be a prob-
lem 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.
