The current setting can be queried by using the
DIFFERENCE:
DisplayPort settings are available in certain models, -D letter in the model name refers to
that (see the Model Comparison table).
9.10.1. Enabling DP Power
This property allows providing 1.5W (500mA @ 3.3W) power on DP_PWR pin. The default value is true.

Parameters
Identifier Parameter description
<enable_power> The matrix can provide 1.5W power on
each Displayport connector.
Example

9.10.2. Enabling Forced Link Training
Command and Response #linktraining
SET·/MEDIA/PORTS/VIDEO/<out>/SETTINGS.DpForcedMode=<forced_mode>
ç
pw·/MEDIA/PORTS/VIDEO/<out>/SETTINGS.DpForcedMode=<forced_mode>
æ
Parameters
Identifier Parameter description
<forced_mode> It allows the configuration of the output
link training parameters (Link datarate,
Link lane, Swing / pre-emphasis)
manually, the link training process is
skipped.
Example
ç SET /MEDIA/PORTS/VIDEO/O1/SETTINGS.DpForcedMode=true
æ pw /MEDIA/PORTS/VIDEO/O1/SETTINGS.DpForcedMode=true
GET command.
Parameter values
true: The matrix sends 1.5W power on the
chosen port.
false: The matrix does not provide any power
on the chosen port.
Parameter values
true: The link training mode is Forced. Link
datarate, Link lane count and Swing / pre-
emphasis parameters can be modified.
false: The link training mode is Automatic.
The matrix and the agree on the link training
parameters automatically without any user
interruption.

9.10.3. Setting the Forced Lane Number
Command and Response
SET·/MEDIA/PORTS/VIDEO/<out>/SETTINGS.DpForcedLaneCount=<lane>
ç
pw·/MEDIA/PORTS/VIDEO/<out>/SETTINGS.DpForcedLaneCount=<lane>
æ
Parameters
Identifier
<lane> DisplayPort data transmission
proceeds through the lanes. This
defines the number of lanes used.
Example
ç SET /MEDIA/PORTS/VIDEO/O1/SETTINGS.DpForcedLaneCount=2
æ pw /MEDIA/PORTS/VIDEO/O1/SETTINGS.DpForcedLaneCount=2

9.10.4. Setting the Forced Link Data Rate
Command and Response
SET·/MEDIA/PORTS/VIDEO/<out>/SETTINGS.DpForcedLinkRate=<data_rate>
ç
pw·/MEDIA/PORTS/VIDEO/<out>/SETTINGS.DpForcedLinkRate=<data_rate>
æ
Parameters
Identifier
<data_rate> The data rate per lane.
Example
ç SET /MEDIA/PORTS/VIDEO/O1/SETTINGS.DpForcedLinkRate=HBR2
æ pw /MEDIA/PORTS/VIDEO/O1/SETTINGS.DpMaxLinkRate=HBR2
