You can configure VMware Blast options for remote desktop and published application sessions that use the VMware Blast display protocol.
You can allow H.264 decoding and High Efficiency Video Decoding (HEVC). You can also allow increased color fidelity when H.264 decoding is allowed.
The maximum resolution that is supported, and whether HEVC 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.
You can configure H.264 decoding and high color accuracy before or after you connect to a server.
In earlier Horizon Client versions, you had to select a network condition option to provide the best user experience with VMware Blast. In this release, Horizon Client senses current network conditions and chooses one or more transports to provide the best user experience automatically.
To use H.264 decoding, Horizon Agent 7.0 or later must be installed.
To allow increased color fidelity when H.264 decoding is allowed, Horizon Agent 7.4 or later must be installed.
- Click the Options button in the menu bar and select Configure VMware Blast.
If you are logged in to a server, you can click the Settings (gear) icon and select VMware Blast.
- To allow H.264 decoding in Horizon Client, 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 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.
- (Optional) To allow increased color fidelity when H.264 decoding is allowed in Horizon Client, select the High Color Accuracy check box.
When this option is selected, Horizon Client uses high color accuracy, but only if the agent supports high color accuracy. Selecting this option might reduce battery life and performance. This feature is disabled by default.
- To allow HEVC, select the Allow High Efficiency Video Decoding (HEVC) check box.
When this option is selected, performance and image quality is improved if the client machine has a GPU that supports HEVC decoding.
- Click OK to save your changes.
Changes for H.264 take effect the next time a user connects to a remote desktop or published application and selects the VMware Blast display protocol. Your changes do not affect existing VMware Blast sessions.
