Multimedia redirection (MMR)

Determines whether MMR is enabled for client systems.

MMR is a Microsoft DirectShow filter that forwards multimedia data from specific codecs on View desktops directly through a TCP socket to the client system. The data is then decoded directly on the client system, where it is played.

The default value is Allow. If client systems have insufficient resources to handle local multimedia decoding, change the setting to Deny.

MMR does not work correctly if the client system's video display hardware does not have overlay support.

USB Access

Determines whether desktops can use USB devices connected to the client system.

The default value is Allow. To prevent the use of external devices for security reasons, change the setting to Deny.

Remote mode

Determines whether users can connect to and use desktops running on vCenter Server instances. If set to Deny, users must check out the desktop on their local computers and run the desktop only in local mode. Restricting users to running desktops only in local mode reduces the costs associated with CPU, memory, and network bandwidth requirements of running the desktop on a back-end server.

The default value is Allow.

PCoIP hardware acceleration

Determines whether to enable hardware acceleration of the PCoIP display protocol and specifies the acceleration priority that is assigned to the PCoIP user session.

This setting has an effect only if a PCoIP hardware acceleration device is present on the physical computer that hosts the desktop.

The default value is Allow at Medium priority.
