You can configure H.264 decoding and network protocol options for remote desktop and application sessions that use the VMware Blast display protocol.

About this task

The maximum resolution that is supported depends on the capability of the graphical processing unit (GPU) on the client. A GPU that can support 4K resolution for JPEG/PNG might not support 4K resolution for H.264. If a resolution for H.264 is not supported, Horizon Client uses JPEG/PNG instead.

Prerequisites

This feature requires Horizon Agent 7.0 or later.

Procedure

  1. In the desktop and application selector window of Horizon Client, click the Settings icon in the upper-right portion of the window, and select VMware Blast in the left pane of the Settings window.
  2. 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 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 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.
