Introduced in Horizon 8 (2106): Leverage High Efficiency Video Coding (HEVC) with High Dynamic Range (HDR) encoding to provide higher graphical quality with improved color range and contrast. The Blast Worker process determines whether UDP is enabled on the agent and allowed on the client. Actual results will depend on the application workloads and usage patterns. One of the goals for Blast Extreme is to provide an excellent out-of-the-box configuration for most local area network (LAN) use cases, negating the need to perform complex tuning or learn hundreds of policy settings. Fortunately, Blast Extreme can be tuned to handle all of these situations. To collect logs on a Mac, you can use the. Display communication protocols provide end users with a graphical interface to a remote desktop or published application. Blast Extreme will always resort to using more bandwidth, if necessary, to prevent the session from crashing. Blast Extreme is a next-generation display protocol, developed by VMware. The next component to optimize is the Windows operating system. Controls the relative brightness of the paperwhite level. Blast Extreme supports four codecs: JPG/PNG, H.264, HEVC (H.265), and the new Blast Codec. The Horizon Performance Tracker does not currently indicate HCA mode when NVIDIA encoding is used. captures the screen and handles everything within the session. Settings made directly in the registry are dynamic and take effect immediately, whereas those requiring a client setting will take effect only after the client disconnects and reconnects to a live session. Added information about OpenGL and DirectX compatibility with hardware GPUs in remoted physical PCs. VNCRegionEncoder_Create: region encoder BlastCodec. Problem is with second file, which is growing sometimes up to 15GB, then new files are created. The latest innovation for Blast Extreme is the Blast Codec. Note: Despite the presence of a physical GPU, Blast Extreme with physical desktops is not able to offload H.264, H.264 with High Color Accuracy, or High Efficiency Video Coding (HEVC) encoding, even with NVIDIA GPUs. Look for Desktop & End-User Computing and under this category, select Download Product under VMware Horizon. Mark Ewert has been working in IT for over 25 years, with nearly two decades hands-on experience with VMware technologies. VNCRegionEncoder_Create: region encoder h264 4:4:4. To set up the Horizon environment for Blast Extreme, administrators open various firewall ports and select Blast Extreme as the default display protocol or as a possible protocol choice for end users: Use the correct version of Horizon and related components: With Horizon 7 version 7.7, VMware introduced the ability to broker physical desktop machines running Windows 10 version 1803 and 1809 Enterprise Edition, via the Blast Extreme display protocol. Here you can create an account, or login with your existing Customer Connect / Partner Connect / Customer Connect ID. Intelligence to determine and accommodate varying network conditions. If testing reveals the Blast Codec is not yet able to fully support an application or use case, simply switch to one of the other three codecs for now. If possible, implement network Quality of Service (QoS) to further help maximize the capacity of these Internet circuits and prevent competing network traffic from degrading the performance of Blast Extreme. A certificate thumbprint is a cryptographic hash of a certificate.
VMware Horizon View: GPO Optimizations for Power Users HDR: Relative Brightness of the Paperwhite Level. In other words, the settings do not directly enable the feature, such as forcing all connections to use H.264. Use NVIDIA Tesla or newer GPUs.
See the latest innovations in Blast Extreme in VMware Horizon The Connection Server returns the connection information for the virtual desktop or RDSH server that provides remote applications (on TCP port 443). TLS version and encryption defaults are routinely updated to reflect current best practices. The following tuning recommendations apply to all WAN conditions. Activity Paths are guided and curated learning paths through modules and activities that help you cover the most content in the shortest amount of time. Yes: Select Allow H.264 Decoding. Update for VMware Horizon 7 versions 7.1 and 7.2. Horizon Cloud on Microsoft Azure Activity Path.
Poor audio quality with BLAST/RTAV? - VMware Some even suffer from packet loss, where packets never arrive at the destination at all! However, compared to other codecs, H.264 requires more processing power to perform its encoding and decoding operations.
Guidelines when Troubleshooting Horizon Blast Protocol Performance Value: 1. Workspace ONE Access, formerly known as Identity Manager, is a powerful tool. Introduced in Horizon 8 (2111) is the ability to adjust the size of the Blast codec cache.
Understand the basics of VMware Blast Extreme vs. PCoIP The Blast Worker process determines whether UDP is enabled on the agent and allowed on the client. To use Blast Extreme, the virtual or physical desktop pool or RDSH server farm must first be configured to use the protocol as the default, or be configured to allow users to choose it. If the testing is not successful, use JPG/PNG. HEVC requires NVIDIA GPUs to be installed in the ESXi hosts to offload encoding. If Sound Card is not available in the Settings pane, click Add Device > Sound Card, then click Add. All TCP and UDP connections use TLS to encrypt communication. EncoderBuildToPNG Enables or turns off build-to-lossless mode for the JPG/PNG codec. The following table documents the key codec and transport settings. Applications that require higher graphical quality with improved color range and contrast, such as digital photography. Deselect all other codecs and codec options.
VMware Blast Extreme H264maxQP The lowest quality that H.264 will start with before building the screen to higher quality. However, in testing it has been determined that only Intel GPUs support OpenGL applications in a remote session. Computer Configuration -> Policies -> Administrative Templates -> VMware Blast -> Max Frame Rate. Except under unique conditions, it is not possible to increase quality while limiting system resources. Deselect all other codecs and codec options. SwitchEnc: 1 Screen 0 switching to h264 4:4:4 encoder. Access technical, third-party tips, tricks, and how-tos. We also frequently discover that the underlying ESXi hosts are overutilized and are exhibiting clear indicators of problems impacting user experience such as high CPU Ready times. There are some special considerations when supporting work-from-home and home-office-to-cloud use cases: The other common reason to tune display protocols is to increase quality. Deselect all other codecs and codec options. With an internal connection, the client, the server, and the virtual desktop or RDSH server are all inside the corporate network. The future successor to JPG/PNG, the Blast Codec provides a high-quality user experience while using significantly less CPU and network bandwidth required by other codecs. If the end user can be interrupted, or if you are performing configuration testing, the easiest way to see the running session configuration is to use the Horizon Performance Tracker if it is installed. We have many more paths than are shown here. However, it does increase client CPU utilization by up to 200 percent for the duration of the redirection (from an average of 8 to 24 percent on a sample test system). If UDP is not enabled or is blocked, the initial TCP connection (Step 3) is used instead. Testing has shown this reduces the bandwidth required to support such content by up to 80 percent. If full-motion graphics must be supported, such as streaming video, use the encoder switch to dynamically switch between the Blast Codec or JPG/PNG and the H.264 codec. Utilize this tool to get you part of the way there. Note: Requires Horizon Agent 7.11 and Horizon Client 5.3 or later. Access technical, third-party tips, tricks, and how-tos. Click the View All button for the full list. HCA turns off 4:2:0 chroma subsampling, providing a 4:4:4 sample rate instead. Therefore, images compressed using JPG cannot be decoded and restored to the same quality they had before compression. As its name implies, the JPG/PNG codec leverages two image formats, JPG and PNG, to encode and decode display content. These settings will override all other Blast Extreme settings. Another key Blast Extreme innovation is the encoder switch. After you apply the policy, the system stores the settings in the registry key HKLM\Software\Policies\VMware, Inc.\VMware Blast\config.

The table in each section outlines the settings configured by the application template. Same applications as for the JPG/PNG codec and the H.264 with HCA codec. Figure 3: Tunneled Connection from Client to Agent Through the Connection Server. Easily manage VM Profile settings across images. MinBandwidthKbps The minimum bandwidth used by all services, in kilobits per second. Special note about NVIDIA GPU supported use cases: Using NVIDIA GPUs to support H.264 and High Efficiency Video Coding (HEVC) substantially increases session bandwidth. Note that HDR is an optional capability of HEVC (High Efficiency Video Coding, H.265) and requires an NVIDIA hardware GPU. Some of the codecs and codec options can be enabled using the Horizon Client, as shown in the following screenshot.

Be certain to test key applications and multimedia content before widespread deployment. High Efficiency Video Coding (HEVC) While typically supporting just a single user, most households do not yet have LAN-speed Internet connections (gigabit Ethernet). Then select the appropriate Horizon version and click Go To Downloads. If the administrator has enabled additional remote experience features such as USB redirection or client-drive redirection (CDR), the administrator can choose whether traffic for these features will be carried on virtual channels within the Blast session or on separate dedicated connections. Screen 0/1 @ Resolution: 3840 x 2160, New in Horizon 8 (2106): HEVCwith High Dynamic Range (HDR) Encoding, VNCSERVER-WIN32: Enabled HDR on display \\.\DISPLAY9 EncoderHEVCEnabled Enables or turns off support for the HEVC codec (H.265). The VMware virtual desktop pool setting in the Horizon administrative console You'll need to set the video resolution and the monitor account to their maximum values. In systems with multiple monitors, the encoder switch will use the best codec for each screen. If you are using Horizon Client for macOS 5.0 or later, this Horizon Collector functionality is included in Horizon Client. End-users access to their personalized virtual desktops or remote applications from company laptops, their home PCs, thin client devices, Macs, tablets, or smartphones. Start here to discover how the Digital Workspace empowers the Public Sector. Yes: Select Allow High Efficiency Video Coding. Do not attempt to support high-quality use cases over a WAN or poorly functioning network. On the VM registry I configured the following GPO values: In addition, I also tried to manually configure this registry setting: Configuring the Client Clipboard Memory Size (value of 8192 decimal) [despite the fact that is was configured in the above GPO When viewing the Blast logs on the VM I see the following entry: Blast-Worker-SessionId1.log But that's not really the case on corporate owned, standardized and locked down devices.
