8) Source - Sink Auto fit Function

Page 5
This function applies to the situation when the source's HDMI version exceeds
the sink's HDMI version. (This function can be used to fix the deep color, 1080P, 1080i, 2ch
audio, multi channel audio issue.)
For example:
When the TV is HDMI 1.2 version and PS3 source is HDMI 1.4 version, it will
output HDMI 1.2 version.
(1) Under default mode, this machine will output 1.2 version HDMI signal (1080P
and stereo audio).
(2) Under button mode.
There are two modes to update the EDID data according to the DIP setting.
When the DIP is in default mode (0, 0, 0), the matrix will be in mix mode.
A、When the source is HDMI1.4, (e.g., HDMI output from PS3), OUTPUT1 to 4
both support HDMI1.4 displays, press “selection of OUTPUT1” and “lock key"
simultaneously, the machine will output HDMI1.4 signals.
B、When the source is HDMI1.4, (e.g., the HDMI output from PS3), OUTPUT 1 to
4 are connected to the displays that can only support HDMI 1.2 MAX, press
"selection of OUTPUT1" and "lock key" simultaneously (no matter whether
HDMI OUTPUT port is connected to the display that supports HDMI 1.4 or not), it
will output HDMI 1.2 signals.
When the DIP is in default mode (0, 0, 0), the matrix will be in copy mode.
Note: The method to reset the machine to default EDID setting: Disconnect the input and
output. Please press "selection of OUTPUT1” and “lock key" Simultaneously for at least 3
seconds, and EDID of all the four input ports will be reset to the default setting. The audio
setting of the default EDID is stereo. It is suitable for TV sets.

Note1: The matrix will mix the EDID data of the sink devices. The mixed EDID data will
use the lowest resolution of the video and the least channel number of the audio. For
example, some sink device support 1080P, some sink device only support 1080i, some
support 5.1 audio, but some only support stereo. Then the mixed EDID will be 1080i and
stereo.
Note2: If user wants to just use one sink device’s EDID data, this DIP setting can be
used.
Attention: Please insert or extract cables gently.
