Video Input Source [1..2] OptimalDefinition Threshold60fps
For each video input, this setting tells the system the lowest resolution where it should transmit
60fps. So for all resolutions lower than this, the maximum transmitted framerate would be
30fps, while above this resolution 60fps would also be possible, if the available bandwidth is
adequate.
Requires user role: ADMIN
Value space: <512_288/768_448/1024_576/1280_720/1920_1080/Never>
512_288: Set the threshold to 512x288.
768_448: Set the threshold to 768x448.
1024_576: Set the threshold to 1024x576.
1280_720: Set the threshold to 1280x720.
1920_1080: Set the threshold to 1920x1080.
Never: Do not set a threshold for transmitting 60fps.
Video Input Source 1 OptimalDefinition Threshold60fps: 1280 _ 720

Video Input Source [1..2] Quality
When encoding and transmitting video there will be a trade-off between high resolution and
high framerate. For some video sources it is more important to transmit high framerate than
high resolution and vice versa. The Quality setting specifies whether to give priority to high
frame rate or to high resolution for a given source.
Requires user role: ADMIN
Value space: <Motion/Sharpness>
Motion: Gives the highest possible framerate. Used when there is a need for higher frame
rates, typically when a large number of participants are present or when there is a lot of
motion in the picture.
Sharpness: Gives the highest possible resolution. Used when you want the highest quality of
detailed images and graphics.
Video Input Source 1 Quality: Motion

Introduction Web interface System settings System settings
Video MainVideoSource
Define which video input source shall be used as the main video source. The video input source
is configured with the "Video Input Source [1..n] Connector" setting.
Requires user role: USER
Value space: <1/2>
Range: Select the source to be used as the main video source.
Video MainVideoSource: 1
Example:
Video DefaultPresentationSource
Define which video input source shall be used as the default presentation source when you
press the Presentation key on the remote control. If using a Touch controller this setting has no
effect. The Video Input Source n Connector setting defines which input connector to use for
input source n.
Requires user role: USER
Value space: <1/2>
Range: Select the video source to be used as the presentation source.
Video DefaultPresentationSource: 2
Example:
Video Input HDMI [1..1] RGBQuantizationRange
All devices with HDMI inputs 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 source.
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.
Video Input 1 HDMI 1 RGBQuantizationRange: Auto
