Configure Omnissa Horizon Blast Options

You can configure Horizon Blast options for remote desktop and published application sessions that use the Horizon Blast display protocol.

You can configure H.264 decoding before or after you connect to a server. H.264 is an industry standard for video compression, which is the process of converting digital video into a format that takes up less capacity when it is stored or transmitted.

After you connect to a server, the Horizon Blast setting is visible only if Horizon Blast is the preferred protocol.

Prerequisites

Depending on the Horizon Agent version that is installed, a Horizon administrator can use agent-side group policy settings to activate or deactivate Horizon Blast features, including H.264. For information, see "Horizon Blast Policy Settings" in the Horizon Remote Desktop Features and GPOs document.

Procedure

  1. Start Omnissa Horizon Client.

  2. Tap Settings at the bottom of the Horizon Client window and tap Horizon Blast.

    If you are logged in to a server, the Horizon Blast setting is visible only if Horizon Blast is the preferred protocol.

  3. To allow H.264 decoding in Horizon Client, tap and toggle the H.264 option to on.

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

  4. To display a warning message when the network is unstable, toggle the Network State option to ON.

Results

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