4. EDID Management
The Extended Display Identification Data (EDID) is used by the source device to match its
video resolution with the connected display. By default, the source device obtains its EDID
from the first connected display. When displays with different resolutions are connected to
the splitter, the 3-pin DIP switch on the front panel and the 4-pin DIP switch on the rear panel
can be used in combination to set the EDID to a fixed value.
Switch Status
Description
L.RES
The splitter reads all EDID information from all connected displays,
and choose the one with lowest resolution passing to the source.
PRESET
In this mode, the 4-pin DIP switch on the rear panel can be used to
select predefined EDID and customize a specific EDID as need.
H.RES
The splitter reads all EDID information from all connected displays,
and choose the one with highest resolution passing to the source.
⚫Predefined EDID setting
When the 3-pin DIP switch on the front panel is in PRESET mode, the 4-pin DIP switch on
the rear panel can be used to set the EDID to a built-in fixed value. Use the following table to
determine the settings for the 4-pin DIP switch for specific video resolution and audio
capabilities.
When in the lower position, the switch represents “1”, while putting the switch in the upper
position, it represents “0”.
