INFO: This window appears only when the selected port is
DisplayPort. See the Model Comparison
input.
Click on a port to display its properties; Signal status information and
the most important parameters.
General Tab- General
General tab in the input port properties window
Port name
The name of a port can be changed by typing the new name and
clicking on the Set button. The following characters are allowed when
naming: Letters (A-Z) and (a-z), hyphen (-), underscore (_), numbers
(0-9), and dot (.). Max length: 63 characters.
Mute
The incoming signal can be muted/unmuted by pressing the button.
If the port is muted, button text is Unmute. In this case, no signal is
transmitted from the input port.
Lock
The port can be locked to the currently connected output ports by the
button. If the port is locked, button text is Unlock. In this case the mute
state and the crosspoint state of this port cannot be changed.
Switch to all
The input port will be switched to all output ports.
Emulated EDID
The name of the currently emulated EDID (displays the Monitor Name in
the EDID menu).
General Tab - Displayport Link
This section has a built-in help in the LDC. Click on the  icon to open

transmission.
▪ DisplayPort disabled, test pattern enabled: This function makes
possible to route the analog audio towards the output without
any video transmission. Enabling testpattern will disable the
DisplayPort connector.
* Test pattern generator option appears only in -A or -Audio suffixed
models, where there is an analog audio port beside the DP port.
Provide DP Power
Enable /Disable: DisplayPort input ports are capable of providing
▪
about 1.5 W (500 mA @ 3.3V) power on the DP_PWR pin. As in
DisplayPort copper cables this pin is not connected, the setting
has no effect when a PC or a media player is attached to the
respective port. Typically, this feature can be used for powering
DisplayPort dongles, adapters and active optical cables that do
not have external power supplies. The matrix is also capable
of detecting and displaying short circuit conditions where the
current exceeds the 500 mA limit. Adjusting these settings may
help restarting or powering down the connected device.

HDCP enable
▪ Disable HDCP on input: The connected source will detect that the
matrix is not HDCP-compliant and turn off authentication if the
content allows it.
▪ Allow HDCP 1.4 only *: The connected source will detect that the matrix
is compliant with HDCP 1.4 but not compliant with HDCP 2.2.
Allow HDCP 2.2 and HDCP 1.4: The connected source will detect
▪
that the matrix is compliant with HDCP 2.2.
▪ High Value mode (limit switching to HDCP 2.2 sinks): Any version of
HDCP is allowed on the input but the incoming signal is always
internally upconverted to HDCP 2.2 content and thus cannot be
switched to HDCP 1.4 sinks.
*The availability of this setting depends on the hardware version of
the input board (V1x_) and the port type (HDMI). The hardware version
can be found in Status Tab in the LDC or in the
Device Info submenu in the LCD.
Link training
This is a status information about the success of the link training. The
result of the connection can be succeeded or not ready.
Link training is a process where the source (PC, laptop, media server)
and the sink (matrix) agree on a data rate, lane count and electrical
parameters. The successful link training is a pre-requisite of the video
transmission. If the quality of the DisplayPort cable is insufficient to
reliably handle higher data rates, link training will result in a lower data
rate where stable connection between the source and the matrix can
be maintained.
Clicking on the Restart Link Training button starts to build up the
connection again between the matrix switcher and the source (it
happens automatically when the source is connected). It is equal with
unplug and reconnect the DP connector.
