In Horizon Client 4.0 and later, 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

Verify that you have Horizon Client 4.0 or later. VMware Blast is not supported in earlier Horizon Client versions. This feature also requires Horizon Agent 7.0 or later.

Procedure

  1. Tap Settings at the bottom of the Horizon Client screen.
  2. Tap VMware Blast.
  3. Configure the decoding and network protocol options.

    Option

    Description

    H.264

    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.

    UDP

    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).

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.
