VIC workstations have the ability to control their screen layout independently of the VTS Server. The display options that will be available to the VIC are granted at the server by way of one or more Realm Display Setup tags added to the application. See Realm Display Setup Tags for configuration details.
Using one or more tags embedded within the application provides you with a fine level of control over how the application may be displayed on the VIC. For example, for a given application some VIC stations might be desktop workstations while others might be hand-held devices. Each type of station could connect to the application via a different configured realm and thereby have access to the most appropriate display settings for their screen.
Note: if a Realm Display Tag is not added to an application, the effect is no different than the situation before this tag was available. The application will run normally, using the display settings from the VTS/IS.
