Click on any of the output buttons to display its properties.
Output Port Properties Tab
The upper section contains the following settings:
Current output
displayed in the header.
All outputs
INFO: After closing this window, the Current Output option will be selected regardless of which was active
at the time of closing. It is to avoid setting All Outputs by mistake.
Reload Factory Defaults
Current output: Reloads the default values to the currently selected output.
All outputs: Loads the factory default values to all outputs.
Settings
The factory default settings give good results in most cases. Modify only if encountering problems with
output signals.
▪ Pre-emphasis: ON is recommended. Use OFF setting if the cable between the OUTPUT port and the
display device is very short.
▪ Internal termination: Always use ON.
▪ Mute
▪ De-skew: Adjust setting if the output signal is noisy. Default setting gives good result in most cases.
▪ Output Mode: This setting is used to determine the output signal. DVI and HDMI 1.3 signals are all
supported, with optional DVI to HDMI or HDMI to DVI conversion.
ATTENTION! HDMI YUV to RGB colorspace conversion is not supported. If the two outputs’ signal is
different (e.g. OUTPUT 1 distributes HDMI signal, OUTPUT 2 DVI signal), the input HDMI signal has to be
in RGB color format. To avoid conversion issues set an EDID which supports RGB colorspace or set the
source device to send the signal with RGB colorspace.
INFO: Auto output mode function determines the output signal by the connected device’s EDID on the
OUTPUT.
INFO: Modifying the Pre-emphasis, Internal termination or De-skew parameters on an output channel
switches the other output channel’s settings together.
