iPATH Agility Controller
4.4.2.2 Dashboard > Settings > Transmitters
This page applies a standard global configuration to all transmitters.
Magic Eye
Determines whether the Magic Eye feature should be enabled on Agility (excluding Agility Revision 1) transmitters. Magic Eye
works to overcome the issues with increased bandwidth usage caused by 'dithering' techniques used on some computers, such as
Apple Macs. See the Agility Dual user guide for more details.
DDC
Determines whether video configuration details should be harvested from connected display screens or a static fixed EDID report
should be used. Care must be taken when selecting a Dual Link Video resolution as only Agility Dual units support a Dual Link
Video resolutions. In the case of a Dual Link EDID being set in the Global settings, no EDID will be set on Video port 2 of the
Agility Dual transmitters.
EDID optimisation
When this option is ticked, the Transmitters will compare the native resolution settings of their monitors when switching. If the
monitor has the same native resolution as the previous one, the new EDID is not sent to the graphics card. This speeds up
switching as the graphics card does not have to go through a hotplug detect routine when a new receiver is switched to that
channel. If the new receiver has a monitor with a different native resolution, then the EDID will be updated to allow for a change
in video mode.
Hot Plug Detect Control
Determines whether to enable hot plug detection for monitors. By default this is enabled.
Hot Plug Detect Signal Period
By default this is set at 100ms, which is sufficient for most graphics cards. Occasionally it may be necessary to adjust this. A
technical support engineer will advise if necessary.
Background Refresh
The number of frames between sending an entire frame of video data. Setting this to a longer period or disabling this will reduce
the bandwidth required.
Compression Level
The newer AFZ+ codec compliments the existing AFZ codec by providing greater compression for increased speed where pixel
perfect results are not the primary focus. The transmitter video configuration page allows you to choose the required compression
mode. 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 the mode:
• 'AFZ only (pixel perfect),
• 'AFZ+ Minimum compression',
• 'AFZ+ Middle compression', or
• 'AFZ+ Maximum compression'.
USB Speed
Select Low/full speed or High speed USB operation.
