Virtual Displays is an optional portability feature. It allows you to design your MediaLists for portability in cases where you are moving your show/presentation from venue to venue; or for environments where different physical displays are swapped in/out periodically. The goal is to create MediaLists that will work at any venue without having to edit the MediaList to customize it for the venue display hardware.
The Virtual Display simply maps to physical display (Figure 1) and you can change that mapping at any time . You can use a Virtual Display where ever you assign a Target Display to an item (including MediaItems, Load Templates, and Reference Dimensions). For example, on your design development system, Virtual_Display.1 could map to Lab Display2. Then when you arrive at your show venue, you can reassign Virtual_Display.1 to map to Venue Display3 with just a few clicks. Then any MediaItem that uses Virtual_Display.1 as its Target Display, will automatically now get played on Venue Display3. That saves you from the trouble of having to change the Target Display on potentially lots of MediaItems and avoids any resulting editing errors in the process.
Usage is fairly simple.
Menu Locator: Media List Editor > Tools > Displays > Manage Virtual Displays .
Manage Virtual Displays pops up a List Editor of existing Virtual Displays. Select an item in the list, then Click the Edit button to open the Virtual Display Editor (Figure 4).
