Application Settings

You can use properties in the setting-list section to configure application settings. All the properties are optional.

Property	Description
screen_scaling	Configures display scaling. Valid values are "1/2", "2/3", "3/4", "Auto-fit", or "No Scaling".
screen_resolution	Configures the screen resolution. Valid values are "1024*768", "1280*1024", "1600*1200", "Auto-fit", or "No Scaling".
enable_log	Enables or deactivates the log collection feature. Valid values are "true" or "false".
send_log_email	The email address, for example, "[email protected]", to send log files. This email address appears in the To: field by default when a user uses the log collection feature. See Manually Retrieve and Send Horizon Client Log Files.
all_monitor	Enables or deactivates multiple-monitor mode. Valid values are "true" or "false".
default_startscreen	Configures the Horizon Client default view. Valid values are "recent" or "servers".
ssl_tls	Configures the security protocol, or protocols, that Horizon Client uses. Valid values are "tlsv1.1", "tlsv1.2", or "tlsv1.1,tlsv1.2". If you specify this property without a valid value, "tlsv1.1,tlsv1.2" is used.
ssl_cipher_string	Specifies the default TLS cipher control string.
security_mode	Configures the certificate checking mode. Valid values are "verify", "warn", or "don't verify".
enable_h264	Enables or deactivates H.264 decoding. Valid values are "true" or "false".
enable_dpi_sync	Enables or deactivates the DPI synchronization feature. Valid values are "true" or "false".
camera	Specifies whether to use the front or back camera on the device. Valid values are "front" or "rear".
enable_unauthenticated_access	Enables or deactivates the Unauthenticated Access feature. Valid values are "true" or "false".
check_signature	Specifies whether to run a verification check of the APK signature when users start Horizon Client. Valid values are "true" or "false". If you do not specify this property, the value defaults to "true". If you set the property to "true" but do not set the signatures property, the verification check compares the APK signature with the signature of the official VMware certificate. If you set the property to "true" and also set the signatures property, the verification check compares the APK signature with the digest values specified in the signatures property.
signatures	Specifies the array of custom signatures to compare the APK signature with when the check_signature property is set to "true". For each signature object in the array, you must specify values for algorithm and digest.
algorithm	Specifies one or more hash algorithms used to generate the digest value of a custom signature. Valid values are "MD5", "SHA-1", and "SHA-256".
digest	Specifies the digest value generated for a custom signature by a given hash algorithm.
