Video Wall: Zone Settings

Userful's "Ultimate" license provides users the flexibility to separate displays within a video wall into multiple zones, thus enabling users to have a video wall playing different content on different zones.
Configuring zones in a video wall enables users to output multiple contents on a single video wall at the same time. Each zone can display its own content or can be incorporated into multiple layouts.
Some things to remember:
- All displays in a video wall setup belong to the default zone.
- A display can be part of multiple zones but can play content of only one zone at a given time.
- Each zone is controlled by the control display. Control Display is the display designated for input and audio capabilities. The user can connect input devices like keyboard, mouse and audio jack to this display and access them across the video wall. Any action taken to this display will have the same effect on the zone/video wall as it would on an independent display (e.g., Resetting this display will reset the entire video wall).
Note: If a display(s) is a part of multiple video wall zones then those zones are known as overlapped zones, some care must be taken when assigning a display to multiple zones.
To add a zone to an existing video wall layout:
- Click an existing video wall to open the “Video Wall Zone Settings” dialog window (do not click on the "PLAY" toggle located in the center of video wall)
- Click "Stop now" link if the zone is playing
- Click “+” icon available to create a new zone
- Select (toggle on/off) the displays for the current zone
- Edit zone name (optional)
- Select the "Control Display" from the drop-down
- Select the Sound Output from the drop-down:
- "Disabled" for no sound output
- "Host Sound Card" for sound output from the Userful host's sound card
- "Control Display" for sound output from the zero client audio socket
- Select "Optimize for" from the drop-down:
- "Video" for optimizing performance while rendering video
- "Text" for optimizing performance while rendering text
- Content can be optimized only if Direct Sync is enabled under Performance Settings
- Please note that Advanced Settings can only be applied to Interactive sources (e.g., Web Browser, Linux Desktop, Cloud Desktop, and certain CMSs) but not to Non-Interactive sources like (e.g. Signage Player, Video Capture etc)
- Max Canvas Size
- "Max Canvas Size" feature gives the admin ability to set the canvas size for dynamically rendered content. This way if you have a very large video wall (say 5x5) you can still run your browser session at 4k resolution and upscale it to fit the display. For optimal and fastest performance, select 1080p from the drop-down.
- Intel® (onboard) GPU: enables dynamic content sessions to take advantage of the onboard GPU for the enhanced content rendering
- Nvidia GPU: enables dynamic content sessions to take advantage of the Nvidia GPU for the enhanced content rendering
- (At a given time, only one video wall zone can be accelerated with each GPU)
- Click “OK” to complete the process
Note: If the video wall with Sound Output assigned to Host Sound Card does not get the desired volume then please adjust the output volume level through Linux Desktop by going to Applications > Sound & Video > Sound
Mapping Zones to Sources
Every zone appears as a separate draggable object under Control Center > Mapping. Once created, zone can be "mapped" or "assigned" to any source using drag-drop functionality.
Note: Changes will not take effect until the "Apply" button is clicked.
Switching between Zones
With Control Center > Mapping it is possible to play or stop the playback temporarily.
To play a zone, click "Play" toggle (available in the center of the zone). Once active, the zone will play the content as per the mapped source. Similarly to stop the playback, click "Stop" toggle (available in the center of the zone).
