Peak bandwidth limiter percentage
The Agility Zero U unit will employ a ‘best effort’ strategy in sending video and other data over the IP network. This means it will use as much of the
available network bandwidth as necessary to achieve optimal data quality, although typically the Agility Zero U unit will use considerably less than
the maximum available. In order to prevent the Agility Zero U unit from ‘hogging’ too much of the network capacity, you can reduce this setting to
place a tighter limit on the maximum bandwidth permissible to the Agility Zero U unit. Range: 0 to 95%.
Background Refresh
The Agility Zero U unit sends portions of the video image only when they change. In order to give the best user experience, the Agility Zero U unit
also sends the whole video image, at a lower frame rate, in the background. The Background Refresh parameter controls the rate at which this
background image is sent. The default value is ‘every 32 frames’, meaning that a full frame is sent in the background every 32 frames. Reducing
this to ‘every 64 frames’ or more will reduce the amount of bandwidth that the Agility Zero U unit consumes. On a high-traffic network this param
-
eter should be reduced in this way to improve overall system performance. Options: every 32 frames, every 64 frames, every 128 frames, every 256
frames or disabled.
Enable Magic Eye
This feature, enabled as standard, aims to reduce the effect of dithering - a technique used by some graphics cards to improve the perceived quality
and color depth of images by diffusing or altering the color of pixels between video frames. The Magic Eye feature increases the frame rate and
eliminates unnecessary network traffic by ignoring the color dithering where it occurs. If the video source is not noisy or dithered then you can
switch off Magic Eye to enable full color accuracy. Magic Eye mode can remain enabled without penalty for video that does not have dither or noise.
Use Default DDC and Choose Default DDC
When the
Use Default DDC
option is unticked, Agility will use the EDID that is reported by the monitor connected to the receiver unit. However, if you
tick the
Use Default DDC
option, you can then select from a range of preset video resolutions from the
Choose Default DDC
drop down box. Once
selected, Agility Zero U unit will report itself to prefer this video mode.
Enable Hot Plug Detect on change of display
When this option is ticked, every time the monitor is changed at the receiver unit, hot plug state changes are sent to the graphics card of the PC at-
tached to the Agility Zero U unit as if a screen has just been attached.
Period of Hot Plug Detect signal
This is the length of time that the hot-plug detect signal is de-asserted. The default of 100ms is sufficient for the majority of HDMI/DP++ graphics
cards, however, a small minority may need to be given a longer a period.
Frame skipping percentage
Frame Skipping involves ‘missing out’ video frames between those captured by the Agility Zero U unit. For video sources that update only infrequently
or for those that update very frequently but where high fidelity is not required, frame skipping is a good strategy for reducing the overall bandwidth
consumed by the system. Range: 0 to 100%.
Compression
Determines the (
AFZ and AFZ+) compression method used for video transmission. Choices are:
• ‘
Pixel perfect
’ - only uses pixel perfect AFZ,
• ‘
Adaptive
’ - guarantees frame rate, builds to pixel perfect,
• ‘
Smoothest video
’ - forces the maximum compression, or
• ‘
Advanced
’ - allows you to choose a fixed compression mode:
• ‘
AFZ only (pixel perfect),
• ‘
AFZ+ Minimum compression’
,
• ‘
AFZ+ Middle compression’
, or
• ‘
AFZ+ Maximum compression’
.
