You can either configure a single display or a group of displays for your calibrated video wall. Creating a group of displays is named Zones.
- To create Zones, click on a video wall beside the play/stop button. This opens the Zone Settings.
- Click the
+button to add a zone.
- Click each display to remove or add it to each zone. Note the zone counter. The number of zones you can create per video wall is dependent on your license. For example, the Standard license offers 1 zone, the Professional license offers 6 zones, and the Enterprise license offers unlimited zone creation.
- The aspect ratio and total resolution of the zone are shown below the display selection. Note that the Output Size pixel count represents the entire canvas of the zone, including calibrated space between displays.
- You can rename the zone and set the Control Display on the right side of the window. The Control Display designates which display outputs audio if available.
- Every zone appears as a separate object that can be dragged and mapped to different resources.
- Once created, map the zone to any source by dragging and dropping it into the source panel.
- Click on the Apply button to implement the mapping.
The Stop icon in the center of the zone denotes that the zone is currently inactive and is not streaming content. To Start a zone click on the icon present in the center of the zone. The icon changes to the Play icon.
The Play icon in the center of the display and the green dot at the top-right corner denote that the zone is currently active and streaming content. To Stop a zone click on the icon present in the center of the zone. The icon changes to the Stop icon.
- Zone Name: Its default value is
Zone-#but you can rename it.
- Control Display: It denotes the Primary display in a Zone. A Zone must always have one Control Display. The Control Display will output audio if desired, and also is the display that peripherals can be connected to if keyboard-and-mouse control of the Zone is required.
- Sound Output: It is disabled by default, audio can be set to play from either the Control Display’s audio outputs (display or endpoint device) or from the audio-out port on the back of the server.
- Optimize For: It is set to video by default. This adjusts the level of compression used when sending video to Zero Clients only. Zero Clients receive data as JPEGs, and these must be compressed to a degree to allow for full 1080p 60fps video playback. This compression can be scaled back if the content is not as fast-paced but a quality output is desired, such as when showing Web content or spreadsheets. Video encodes 4:2:0 color. Text encodes 4:2:2 color. For the best possible video quality and performance, uClients should be used as they stream RTSP video that is compressed much more efficiently and in 4:4:4 color.
Advanced Zone Settings
- Max Canvas Size: It controls content scaling to the video wall. By default, an interactive source has a canvas limit of 1920x1080. This is done both to help performance and to prevent text elements from being unreadably small on large video wall canvases. Setting a larger Canvas Size will allow interactive sources to use more pixels available to them, at the cost of increased CPU and GPU resources used. Direct video sources are always scaled automatically.
- Session (GPU) Acceleration: It allows you to dedicate resources from the Nvidia (or Intel, if available) GPU to perform certain 3D acceleration tasks, such as rendering WebGL applications in a web browser session, or running 3D applications in a Linux desktop or cloud desktop environments. Only one zone can be allocated to this resource at a time and this setting has no impact on direct video sources. Note that Mirror Groups do not support video walls running GPU-Accelerated sessions.
