Port name
The name of a port can be changed by typing the new name and clicking 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 #mute #unmute
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 to the output port.
Lock #lock #unlock
The output port can be locked to the currently connected input port by the button. If the port is locked, button
text is Unlock. In this case the mute state and the crosspoint state of the port cannot be changed.
Last attached display EDID
The name of the last attached monitor's EDID is displayed (shown as Monitor Name in the EDID menu).

DisplayPort settings in the input port properties window
Provide DP Power #dppower
▪ Enable /Disable: DisplayPort output 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.

Link training
▪
▪
INFO: Certain displays require the standard link training process and will not display the video without it.
Link datarate
INFO: This drop-down menu becomes active when the Link training is set to Forced.
The DisplayPort 1.2 standard uses fix data rates on the high-speed lanes. This setting defines the fix datarate.
If the quality of the cable is low, lower data rate setting is recommended.

▪
INFO: RBR and HBR are defined in the DisplayPort 1.0-1.1a standards, while HBR2 was introduced in
DisplayPort 1.2.
Link lane count
INFO: This drop-down menu becomes active when the Link training is set to Forced.
DisplayPort cables have four high-speed lanes, each of them are capable of transmitting data at a rate of
5.40 Gbps.
The following parameters can be set:
▪

▪
Fewer link lanes result in lower power consumption at the transmitter side. With this setting, it is possible to
declare the used number of link lanes.

#hdcp
Auto: The matrix forces the source to send the signal without encryption if the content allows.
Always: The matrix forces the source to send the signal with encryption.
#linktraining
The link training process starts without any user interruption, parameters are set
Automatic:
automatically. Using this setting is highly recommended!
Forced: This mode means that the link training process is skipped, the signal sending based
on the configured values of Link datarate, Link lane count, .

RBR: Reduced Bit Rate uses 1.62 Gbps bandwidth per lane.
HBR: High Bit Rate (HBR) uses 2.70 Gbps.
HBR2: HBR2 is the fastest mode with a data rate of 5.40 Gbps per lane.
1 lane: Transmits data at a rate of 5.40 Gbps.
2 lane: Transmits data at a rate of 10.80 Gbps.
4 lane: Transmits data at a rate of 21.60 Gbps.
