xConfiguration Video Output HDMI [1,2] Location HorizontalOffset
HorizontalOffset and VerticalOffset settings are associated with each video output. These settings
are used to signal the relative position of the displays that are connected to these outputs.
HorizontalOffset = 0 and VerticalOffset = 0 indicates that the display is positioned in center, both
horizontally and vertically. A negative horizontal offset indicates that the monitor is left of center,
and a positive horizontal offset indicates that the monitor is right of center. A negative vertical offset
indicates that the monitor is below center, and a positive vertical offset indicates that the monitor is
above center. The magnitude of the offset indicates how far the display is from center (relative to
other displays).
Example: You have two displays side by side, one in center and one to the left. Then the following
settings will apply: HorizontalOffset = 0 for the center display, HorizontalOffset = -1 for the left
display.
Example: You have two displays, one in center and one below. Then the following settings will apply:
VerticalOffset = 0 for the center display, Vertical Offset = -1 for the lower display.
The default values for the different outputs are:
Video Output HDMI [1] Location: HorizontalOffset = 0, VerticalOffset = 0
Video Output HDMI [2] Location: HorizontalOffset = 1, VerticalOffset = 0
Requires user role:
ADMIN
Value space:
<-100..100>
Range:
The value must be between -100 and 100.

xConfiguration Video Output HDMI [1,2] RGBQuantizationRange
Devices connected to an HDMI output 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
