xConfiguration Video Output HDMI [1,3] RGBQuantizationRange
All devices with HDMI outputs should follow the rules for RGB video quantization range defined in
CEA-861. Unfortunately some devices do not follow the standard and this configuration may be
used to override the settings to get a perfect image with any display. The default value is set to Full
because most HDMI displays expects full quantization range.
Requires user role: ADMIN
Value space: <Auto/Full/Limited>
Auto: RGB quantization range is automatically selected based on the RGB Quantization Range bits
(Q0, Q1) in the AVI infoframe. If no AVI infoframe is available, RGB quantization range is selected
based on video format according to CEA-861-E.
Full: Full quantization range. The R, G, B quantization range includes all code values (0 - 255). This
is defined in CEA-861-E.
Limited: Limited Quantization Range. R, G, B quantization range that excludes some code values at
the extremes (16 - 235). This is defined in CEA-861-E.
Example:
xConfiguration Video Output HDMI 1 RGBQuantizationRange: Full
xConfiguration Video Output HDMI [1,3] CEC Mode
The HDMI outputs support Consumer Electronics Control (CEC). When set to on (default is off), and
the monitor connected to the HDMI output is CEC compatible and CEC is configured, the system
will use CEC to set the monitor in standby when the system enters standby. Likewise the system
will wake up the monitor when the system wakes up from standby. Please note that the different
manufacturers uses different marketing names for CEC, for example Anynet+ (Samsung); Aquos
Link (Sharp); BRAVIA Sync (Sony); HDMI-CEC (Hitachi); Kuro Link (Pioneer); CE-Link and Regza Link
(Toshiba); RIHD (Onkyo); HDAVI Control, EZ-Sync, VIERA Link (Panasonic); EasyLink (Philips); and
NetCommand for HDMI (Mitsubishi).
Requires user role: ADMIN
Value space: <Off/On>
Off: Disable CEC control.
On: Enable CEC control.
Example:
xConfiguration Video Output HDMI 1 CEC Mode: Off
xConfiguration Video Output HDMI [1,3] MonitorRole
The HDMI monitor role describes which video stream will be shown on the monitor connected to the
video output HDMI connector.
Requires user role: ADMIN
Value space: <First/Second/PresentationOnly/Third/Fourth/Recorder>
First/Second/Third/Fourth: Define the role of the monitor in a multi-monitor setup. In a single-
monitor setup, there is no difference between First, Second, Third and Fourth.
PresentationOnly: Show presentation video stream if active, and nothing else.
Recorder: Show all participants, including the local main video. If active, also show the
presentation.

xConfiguration Video Output HDMI [1,3] OverscanLevel
Some TVs or other monitors may not display the whole image sent out on the systems video output,
but cuts the outer parts of the image. In this case this setting can be used to let the system not use
the outer parts of video resolution. Both the video and the OSD menu will be scaled in this case.
Requires user role: ADMIN
Value space: <Medium/High/None>
Medium: The system will not use the outer 3% of the output resolution.
High: The system will not use the outer 6% of the output resolution
None: The system will use all of the output resolution.
Example:
xConfiguration Video Output HDMI 1 OverscanLevel: None
xConfiguration Video Output HDMI [1,3] Resolution
Select the preferred resolution for the monitor connected to the video output HDMI connector. This
will force the resolution on the monitor.
Requires user role: ADMIN
Value space: <Auto/640_480_60/800_600_60/1024_768_60/1280_1024_60/1280_720_50/1280

60/1680_1050_60/1920_1200_60>
Auto: The system will automatically try to set the optimal resolution based on negotiation with the
connected monitor.
Range: 640x480@60p, 800x600@60p, 1024x768@60p, 1280x1024@60p, 1280x720@50p,
