In Horizon Client 4.0 and later, you can configure decoding for remote desktop and application sessions that use the VMware Blast display protocol.


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.


  1. Tap the Settings (gear) icon in the upper-right corner of the Horizon Client screen and tap General settings.
  2. Configure the decoding setting.



    Use H.264 when available

    Select the H.264 check box. 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.

    Always use JPG/PNG

    Deselect the H.264 check box to disable H.264 decoding. When H.264 decoding is disabled, Horizon Client always use JPG/PNG decoding.


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.
