Use TCP if latency is greater than 250 milliseconds. The next component to optimize is the Windows operating system. Note: Requires Horizon Agent 7.11 and Horizon Client 5.3 or later. Blast Extreme is a next-generation display protocol, developed by VMware. By design, Blast Extreme provides an excellent out-of-the-box user experience for typical applications and use cases on LANs. Optimize the desktops and RDSH servers using the VMware Operating System Optimization Tool. If you're experiencing display driver issues (such as a blank screen), before re-installing VMware Tools try forcibly removing the display driver. Yes: Select Allow H.264 Decoding and Allow High Color Accuracy. Yes: Deselect all codecs and codec options (uncheck: H.264, Allow High Color Accuracy, and Allow High Efficiency Video Coding). VNCEncodeRegionNvEncGetHandle: region encoder NVIDIA NvEnc H264 using YUV 4:2:0 color space. Log File Locations for Client and Agent Components Consider using the HEVC codec. On the client, this means near universal H.264 GPU decode support, because nearly all devices with graphics cards manufactured since 2013 have hardware H.264 decode support, including cell phones and most thin clients. The actual size of the cache will be the lesser of this value, and the value of DecoderImageCacheSizeKB set on the client but cannot exceed half of the available RAM. Deselect all other codecs and codec options. If extensive use of graphically intensive content such as streaming video must be supported, consider asking users to view this content in a window, instead of full-screen mode. The port used by the Blast Secure Gateway on the Unified Access Gateway can be customized (for example, it can use TCP 443). Our Communities feature the top Digital Workspace Experts across the world and 3rd-party content. High Efficiency Video Coding (HEVC) Troubleshooting Display Issues with the Horizon Blast Protocol (90139) Be certain to test key applications and multimedia content before widespread deployment.

Horizon 7.10: Enabling dynamic codec switching For more information, see "VMware Blast Policy Settings" in the Horizon Remote Desktop Features and GPOs document. Another key Blast Extreme innovation is the encoder switch. Continuing the theme of useful registry key settings you can bake into your image or manually configure for some quick testing, below is a list of corresponding Blast Extreme registry settings to the Horizon 7. Multimedia redirection traffic uses TCP 9427. The VMware Workspace ONE and Horizon Reference Architecture guide provides guidance for architecting Workspace ONE and Horizon deployments. For more information see. 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. Readers should also have a solid understanding of desktop and application virtualization, as well as a good working knowledge of networking and supporting infrastructure, covering topics such as Active Directory, Group Policy, and supporting technologies. Sound is not working in Windows virtual machine (1003425) - VMware Do not attempt to support high-quality use cases over a WAN or poorly functioning network. 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. For more information, see, Worksheet for Creating an Automated Instant-Clone Farm, Setting Up Published Desktops and Applications in Horizon, To configure the remote display protocol at the global entitlement level, see, Administering Cloud Pod Architecture in Horizon.

Test the new Blast Codec. Deploying Hardware-Accelerated Graphics with VMware Horizon The encoder switch also supports High Color Accuracy (HCA) for H.264, enabling it to be used for multimedia content that exhibits color problems or lack of clarity with H.264 alone. Using articles, videos, and labs, this activity path provides the fastest way to learn Workspace ONE! Many of the codec options and Blast Extreme settings can be controlled by administrators. Set on the virtual desktop and RDSH server (agent side). Display resource-intensive multimedia content in a window instead of full screen. For information about administrator settings, end-user settings, and various optimization strategies, see the VMware Blast Optimization Guide. Start with these recommendations before moving on to more specialized settings. How to troubleshoot a VMware Horizon black screen HEVC also requires clients to have graphics cards with H.265 decode support, but fortunately, as with H.264, most client devices manufactured since 2015 have them. I ended up writing a logon script to solve the problem until VMware fixes it. VNCRegionEncoder_Create: region encoder adaptive. Increasing this setting helps improve display quality at the expense of higher bandwidth utilization. Windows desktop and server operating systems are not designed for efficient virtualization. Figure 3: Tunneled Connection from Client to Agent Through the Connection Server. In testing, UDP has been shown to handle packet loss better than TCP in most situations. While most of our environment is running PCoIP, we have also tested with BLAST. The Horizon Performance Tracker does not currently display the codec currently being used per screen by the encoder switch. Increase virtual desktop resources. VMware Blast Extreme Start here to understand the basics of the award-winning product suite. UdpEnabled Enables or turns off support for the UDP transport protocol. MainApp::OnEncoderConfigChanged: Encoder config changed: EncoderBuildToPNG = 1. Note: Dynamic Environment Manager also provides optimization templates for Blast Extreme. 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). This Continued 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. Blast Extreme, runs TCP and not UDP - VMware Applications that require higher graphical quality with improved color range and contrast, such as digital photography. Monitor for high CPU Ready times (which are evidence of processor contention). Setting Frame Rates and Resolution for Real-Time Audio-Video - VMware For lossless support, enable Build-to-Lossless (EncoderBuildToPNG = 1).

The following updates were made to this guide. The client-side settings work in conjunction with the agent-side settings, which administrators can configure, as described in How to Configure Blast Extreme, in the VMware Blast Extreme Optimization Guide. : NVIDIA GPUs will also offload H.264 and HEVC encoding. Workspace ONE Access, formerly known as Identity Manager, is a powerful tool. General Settings The following table describes the general settings in the Horizon Client Configuration ADMX template file. EncoderMaxFPS The maximum frames per second that Blast Extreme will display. Install VMware Horizon Client on end users' machines and have end users access their remote desktops and applications. 4 If using Blast Secure Gateway 5 Not using Blast Secure Gateway 6 Standard encoded RMI 7 RMI over SSL WANs typically have just a fraction of the bandwidth that is available on local area networks (LANs). For this reason, HEVC in Blast Extreme requires that the ESXi hosts supporting the virtual desktops and RDSH servers have NVIDIA Tesla or newer GPUs to offload its encoding. TCP 443 is used between the client and the Connection Server. It also causes some screen content to letterbox, which may impair user experience. Depending on the environment and design requirements, these external URLs can be configured in several different ways: Using multiple ports on a single address (Port Address Translation) The connection continues from the Unified Access Gateway to UDP port 22443 on the agent. Configuration Settings for Administrators, Tuning Blast Extreme for Wide Area Networks, Guidance for Work-from-Home and Home-Office-to-Cloud Use Cases, VMware Horizon Cloud Service on Microsoft Azure, A solid understanding of desktop and application virtualization, A good working knowledge of networking and infrastructure, covering topics such as Active Directory, Group Policy, and supporting technologies. These pages help you understand the breadth of our most popular products. We have many more paths than are shown here. H.264 will provide support for full-motion graphics, whereas the encoder switch will ensure that the most efficient codec is dynamically used for each screen based on screen content. , which uniformly limits the bandwidth of all Blast Extreme services, can also be used to support more difficult network conditions.

Like HEVC, the encoding for H.264 and H.264 with HCA can be offloaded to NVIDIA GPUs installed in the ESXi hosts. HDR also requires Horizon 8 (210) or later with Horizon Agent build 2106-8.3.0-18287218 or later and Horizon Client build 2106-8.3.0-18287501 or later. 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). In this mode, under typical application conditions, Blast Extreme uses the Blast Codec or JPG/PNG codec, both of which are optimized for text and still image quality. EncoderSwitchEnabled Enables or turns off automatic switching between H.264 and JPG/PNG based on screen content. It is designed to support the majority of customer use cases, including not just typical Windows and Linux apps like Microsoft Office, but also SaaS applications, line-of-business apps like Point of Sale, plus any that require low-motion, high-quality graphics support such as CATIA, Photoshop, and AutoCAD. This means the encoder preserves all of the information related to color instead of sacrificing some to increase codec efficiency. 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. This not only provides a genuine hardware GPU to accelerate system and application graphics, it also frees the virtual CPUs for other tasks, helping to improve user experience and system scalability. A stated goal in the VMware Horizon documentation 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." VMware notes that "some use cases and situations require additional tuning, especially for wide area networks . The fewer packets the display protocol puts on the network, the fewer that will be affected by packet loss. The actual size of the cache will be the lesser of this value, and the value of EncoderImageCacheSizeKB set on the agent side but cannot exceed half of the available RAM. The fourth Blast Extreme codec option is HEVC. See our favorite tools, scripts, and flings from various sites. Click the View All button for the full list.
