6. Operation of the EDID management
(For AVG HDMI/DVI matrix switcher,
NOT including the 4x4 model
)
EDID communication introduction
MHD/MDV matrix switcher are built in the EDID data inside, which can recognize most of the displays
and video source. When the display or video source are connected, the EDID communication will start
automatically.
But, the in-built EDID database can’t recognize all the devices. In this case, we need to manage the
EDID manually.
There are three solutions to manage the EDID:
1) Auto EDID Management.
The DV/MHD matrix will copy the EDID data from the most priority display, and using the new EDID
data as to be the standard. ( Check the term 6.1 )
2) Manually EDID switching.
The user can switch the EDID data manually, from a certain output to a certain input. It is the similar
operation to AV signal switching. ( Check the term 6.2 )
3) Factory default management. (Default).
It uses the default in-built EDID database to manage the EDID data. It is useful enough for most of
the cases. (Check the term 6.3)
