You can configure decoding and network protocol options for remote desktop and application sessions that use the VMware Blast display protocol.

About this task

Prerequisites

This feature requires Horizon Agent 7.0 or later.

Procedure

  1. Select VMware Horizon Client > Preferences from the menu bar and click VMware Blast.
  2. Configure the decoding and network protocol options.

    Option

    Description

    Allow H.264 decoding

    Select this option to allow H.264 decoding in Horizon Client. When this option is selected (the default setting), Horizon Client uses H.264 decoding if the agent supports H.264 software encoding. If the agent does not support H.264 software encoding, Horizon Client uses JPG/PNG decoding.

    Deselect this option to always use JPG/PNG decoding.

    Allow UDP networking

    Select this option to allow UDP networking in Horizon Client. When this option is selected (the default setting), Horizon Client uses UDP networking if UDP connectivity is available. If UDP networking is blocked, Horizon Client uses TCP networking.

    Deselect this option to always use TCP networking.

    Note:

    UDP is disabled by default on a Horizon remote desktop. For UDP to work, it must be enabled on the desktop, the client, and the Blast Secure Gateway (BSG).

  3. Close the Preferences dialog box.

Results

Your changes take effect the next time a user connects to a remote desktop or application and selects the VMware Blast display protocol. Your changes do not affect existing VMware Blast sessions.
