Client display settings
Supported on: All Citrix Workspace supported platforms
Description
This option controls how the client displays remote application and desktop to the end user. From the Seamless Window drop down menu, select True to enable the client to request for seamless windows. Select False to enable the client to disable the seamless window display. NOTE: The server may reject the client request even when the setting is set to True. From the Window width, select the preferred values. The available options are 1024 and 800. NOTE: This feature will not take effect if the option Seamless Window is enabled. From the Window height, select the preferred values. The available options are 600 and 734. NOTE: This feature will not take effect if the option Seamless Window is enabled. From the Window percent drop-down menu, select the preferred values. The available options are 50%, 75% and Other. This is a manual method of setting the windows height and width. NOTE: The selected value is applicable to entire screen. From the Shrink work area, select the preferred range. The recommended values are between 3 - 5. Enable Full screen to display the client in a full screen mode.
Registry
HKLM
Software\Policies\Citrix\ICA Client\Engine\Lockdown Profiles\All Regions\Lockdown\Virtual Channels\Thinwire Graphics REG Builder
BETAConfigure the state and elements to generate .reg, PowerShell, Intune, and SCCM outputs.
These exports replicate the policy's registry effect. Editing the registry directly is not the same as applying the GPO through the management console (no gpupdate, no central reporting). Test before production; HKLM changes require administrator rights.
