You can use settings in the server-list section to configure certain features for specific servers.

Setting Description
enableHighResolution Configures the high resolution mode feature. The value property specifies whether the feature is enabled or disabled. The editable property specifies whether users can change the High Resolution Mode setting in Horizon Client. Valid values for both properties are true and false.
enableMultiMonitor Configures the multi-monitor feature. The value property specifies whether the feature is enabled or disabled. The editable property specifies whether users can change the Use Multi Monitors if there are two monitors setting in Horizon Client. Valid values for both properties are true and false.
enableWindowsKey Enables or disables the Windows key for remote desktops. The value property specifies whether the feature is enabled or disabled. The editable property specifies whether users can change the Enable Windows Key for Desktops setting in Horizon Client. Valid values for both properties are true and false.
timezoneSync Configures the time zone for remote desktops and published applications. The isSync property specifies whether to set the time zone automatically. The editable property specifies whether users can change the Set Time Zone Automatically setting in Horizon Client. Valid values for both properties are true and false. If you set isSync to false, you can set the time zone manually by specifying the timezone property.
resolution Configures the screen resolution. The width property specifies the screen width and the height property specifies the screen height. Both values should be less than or equal to the Chromebook window's width and height, otherwise Horizon Client uses the default resolution (the Chromebook window's width and height).
