There is something for every experience level. Like HEVC, the encoding for H.264 and H.264 with HCA can be offloaded to NVIDIA GPUs installed in the ESXi hosts. Horizon Client, on the client device, connects to a Connection Server on TCP port 443 for authentication and to request a desktop or application. UDP does not employ such controls and is therefore well suited for applications like streaming video and online gaming, which need to efficiently send large amounts of data to the client but can tolerate occasional errors. TLS version and encryption defaults are routinely updated to reflect current best practices. How to troubleshoot a VMware Horizon black screen For a detailed list of Blast Extreme features, see the VMware Blast Extreme topic in the VMware Horizon Architecture Planning guide. For more information see Configuring HTML5 Multimedia Redirectionin Configuring Remote Desktop Features in Horizon 7. It also causes some screen content to letterbox, which may impair user experience. VMware Blast Extreme uses the H.264 video encoding standard which any modern mobile device can handle in its GPU, rather than CPU. 1. Applications requiring lossless reproduction of original screen content such as non-diagnostic medical imaging. However, this example can be achieved by disabling support for the H.264 codecs competing options: JPG/PNG and HEVC. Critical Horizon features and components, such as the Blast Extreme display protocol, instant-clone provisioning, VMware App Volumes application delivery, and VMware Dynamic Environment Manager , are integrated with published applications and desktops to provide a seamless user experience and an easy-to-manage, scalable solution. Typical Microsoft Office use, for example, results in a very low display protocol frame rate. Access technical, third-party tips, tricks, and how-tos. The Blast Worker process determines whether UDP is enabled on the agent and allowed on the client. For other browsers, the JPG/PNG codec is used. ) EncoderImageCacheSizeKB Introduced in Horizon 8 (2111). WANs typically have just a fraction of the bandwidth that is available on local area networks (LANs). Get to know EUC vExperts from around the world.

See Enabling the USB Over Session Enhancement SDK Feature. Solved: clipboard redirection - VMware Technology Network VMTN When multimedia redirection (MMR), client-drive redirection (CDR), USB redirection, or some combination of these are enabled by the administrator, this traffic goes through the HTTPS Secure Tunnel on the Connection Server. Be sure to also leverage HTML5 multimedia redirection if browser-based HTML5 content must be supported. 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. Our Communities feature the top Digital Workspace Experts across the world and 3rd-party content. Display resource-intensive multimedia content in a window instead of full screen. HEVC provides up to 50 percent better compression with the same quality as H.264. But that's not really the case on corporate owned, standardized and locked down devices. First introduced in Horizon 7.10, the Blast Codec is rapidly evolving but does not yet support all the optimizations and configuration options available to the other codecs. I'm sure this feature looked awesome on paper. To determine whether the session is using UDP or TCP, review the latest entries in the Blast-Worker-SessionId<#>.log file, and look for the entries such as those shown in the following table. 2 enabled client to server only For information about administrator settings, end-user settings, and various optimization strategies, see the VMware Blast Optimization Guide. You should have: In order to optimize Blast Extreme, it is important to understand two key configurable components: the transport protocol and display protocol codec. Although RAM is rarely the bottleneck, monitor RAM to ensure it is not being over utilized by applications. Monitor for high CPU Ready times (which are evidence of processor contention). A TCP WebSocket connection is made on port 22443 between the client and the virtual desktop or RDSH server. Information on how to enable build-to-lossless mode is covered in the next chapter, How to Configure Blast Extreme. Most settings make the option available to be used (set to 1) or not (set to 0). This detail can be observed by reviewing the logs. While most of our environment is running PCoIP, we have also tested with BLAST. With Horizon 7 version 7.12, support for using Blast Extreme with physical desktop machines running Windows 10 versions 1903 and later was added. Clients 5.3 and later do not. This will force H.264 to start at higher quality and prevent it from expending bandwidth to send initial low-quality screens. No tuning for Network Latency: Low bandwidth / High latency Environments require additional tuning, Please see Tuning Blast Extreme for Wide Area Networks for details. Added recommendations for supporting work-at-home and home-office-to-cloud use cases.

Added information about the Blast Codec, which was introduced in the Horizon 7.10 release, and new information about the encoder switch. Note: Requires Horizon Agent 7.10 and VMware Horizon Client 5.2 or later. The former option allows Blast Extreme to burst and use more bandwidth when necessary, while the latter attempts to more strictly control it. 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. Test the new Blast Codec. Streaming video, for example, may freeze for a moment or pixelate briefly, but otherwise continue playing. When you have created the registry key, re-initiate the connection to your VDI machine. Turn on the sound card: Fusion 7.x and above: Ensure Connect Sound card option is checked. Guidelines when Troubleshooting Horizon Blast Protocol Performance VMware Blast detects the presence of a vGPU system and applies higher quality default settings. While typically supporting just a single user, most households do not yet have LAN-speed Internet connections (gigabit Ethernet). The VMware Blast service ( VMBlastS.exe) manages user sessions, proxies incoming TCP connections, and prepares the Blast Worker process. The following table details the requirements for each codec. If i enable USB Redirection for the Headset, i can choose 48.000 Hz. Controls the relative brightness of the paperwhite level. On the right, switch to the tab named Security Servers. HTML5 multimedia redirection transfers this screen content to the client as HTML5 code instead of far less efficient display protocol traffic. This means most should be considered medium- to high-speed WAN use cases. Information on how to enable the new Blast Codec is covered in the next chapter, How to Configure Blast Extreme. Blast Extreme supports two transport protocols to carry the display traffic between clients and the Horizon infrastructure: TCP (Transmission Control Protocol) and UDP (User Datagram Protocol). The VMware Workspace ONE and Horizon Reference Architecture guide provides guidance for architecting Workspace ONE and Horizon deployments. , which uniformly limits the bandwidth of all Blast Extreme services, can also be used to support more difficult network conditions.
