4.5.4 DASHBOARD > SETTINGS > LOCALS
This page applies a standard global configuration to all locals.
Magic Eye
Determines whether the Magic Eye feature should be enabled on Agility locals. 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 locals.
EDID optimization
When this option is ticked, the Locals 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 remote is switched to that channel. If the new
remote 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.
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 complements the existing AFZ codec by providing greater compression for increased speed where pixel
perfect results are not the primary focus. The local 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:
1 'AFZ only (pixel perfect),
2 'AFZ+ Minimum compression',
3 'AFZ+ Middle compression', or
4 'AFZ+ Maximum compression'.
USB Speed
Select Low/full speed or High speed USB operation.
