New in Horizon 8 (2106): HEVC with High Dynamic Range (HDR) Encoding. The following updates were made to this guide. Used together, the JPG/PNG codec is ideally suited for typical Windows and Linux applications, including Microsoft Office. Blast Extreme is a next-generation display protocol, developed by VMware. This guide is intended for IT administrators and implementors who want to provide end users with the best possible remote display experience. HEVC can also support higher quality at similar compression ratios as H.264, but again at the cost of more processing power with no bandwidth savings. But it can also be used to support graphically intensive applications by leveraging the desktops physical GPU. 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. 1 In VMware Horizon, when using PCoIP Secure Gateway on the Connection Server or Security Server. Blast Extreme is a display protocol built by VMware to deliver an immersive, feature-rich experience for end users across devices, locations, media, and network connections. When traffic must pass through a UDP-hostile network service or device such as a TCP-based SSL VPN, which re-packages UDP in TCP packets, If WAN circuits are experiencing very high latency (250 milliseconds and greater). With the exception of Build-to-Lossless which impacts all screens at all resolutions, each logfile entry denotes the codec used, the number of the screen (monitor) being configured of the total number, and its display resolution. See Enabling the USB Over Session Enhancement SDK Feature. These were typically not sized to handle organizations rapidly shifting their workforces to work-from-home deployments. H264maxQP The lowest quality that H.264 will start with before building the screen to higher quality. HEVC provides up to 50 percent better compression with the same quality as H.264. Note, however, that the encoder switch cannot currently be used with High Efficiency Video Coding (HEVC) or when H.264 and H.264 with High Color Accuracy encoding is offloaded to an NVIDIA GPU. When using Blast Extreme, Unified Access Gateway can be used to bridge between IPv6 VMware Horizon Clients and an IPv4 backend and agents. Use of a solid color with no image or pattern is recommended. Be certain to test key applications and multimedia content before widespread deployment. Mark Ewert is a Senior Product Line Manager, EUC Desktop Products, VMware. VNCEncodeRegionNvEncGetHandle: region encoder NVIDIA NvEnc H264 using YUV 4:4:4 color space. If this functionality is used, configuration settings are created within each users profile in the following registry key: HKEY_CURRENT_USER\SOFTWARE\Vmware, Inc.\Vmware Blast\Config. It also tells whether a GPU is required on the client or server. This is also due to a limitation of desktop-class video drivers. Set up an RDSH server VM and install applications to be remoted to end users. For many customers, maximizing the capacity of these circuits will lead them to optimize Blast Extreme before the needs of any individual home user. The display protocol is transferring 6 frames per second, and estimates of network bandwidth and latency are provided. Screen 0/1 @ Resolution: 3840 x 2160. Another key Blast Extreme innovation is the encoder switch. VMware has built a set of tools and resources to support you and your team as you build out an adoption strategy. Although Blast Extreme has been able to provide a functional desktop and application experience when packet loss is in excess of 20 percent, it is with noticeable degradation to user experience. The VMware Operating System Optimization Tool can be downloaded from, https://flings.vmware.com/vmware-os-optimization-tool. captures the screen and handles everything within the session. The following diagram shows the ports used for an internal connection, and the list that follows describes the order in which the connections are made. By default, Blast Extreme is capped at 30 frames per second (FPS). See our favorite tools, scripts, and flings from various sites. Introduced in Horizon 8 (2106) is support for High Dynamic Range (HDR) encoding to provide higher graphical quality with vastly improved color range and contrast. Use UDP unless the traffic must pass through a UDP-hostile network device such as a TCP-based SSL VPN. NVIDIA Encoded H.264(H.264 Offloaded to GPU). Blast gateway not running when a Certificate generated from IIS is used (89820) - This article outlines a scenario where a generated certificate key cannot be read and Blast fails. Controls the relative brightness of the paperwhite level. 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. Offload H.264 and High Efficiency Video Coding (HEVC) encoding from the ESXi hosts. This will allow Horizon to allocate between 125 MB and 128 MB of video memory to each virtual desktop. EncoderBlastCodecEnabled Enables or turns off the Blast Codec. Note: At this point, the VMware Blast service on the agent side (Horizon Agent on the virtual desktop or RDSH server) proxies the incoming TCP connection. Provide a hardware GPU to support graphically demanding applications such as 3D design, gaming, and photo editing. With non-multimedia workloads, the Blast Codec uses the least bandwidth compared to all other codec options. For extreme low-bandwidth, high-latency, or high-performance uses cases, however, Blast Extreme comes equipped with several tuning options, as described in this guide. 3 enabled server to client only. I'm sure this feature looked awesome on paper. Graeme Gordon is a Senior Staff End-User-Computing Architect, EUC Technical Marketing, VMware. Although JPG/PNG and the Blast Codec are ideal for ensuring still image quality, this capability hinders their ability to efficiently support rapidly moving screen content and motion graphics such as streaming video, video editing, and gaming. One of the easiest methods is to use the Windows Group Policy template provided with each release of VMware Horizon. This ensures that all systems deployed from these templates are configured properly for Blast Extreme. Find all of TechZone's available downloadable content here. Do not attempt to support high-quality use cases over a WAN or poorly functioning network. Moving to the cloud? The connection continues from the Unified Access Gateway to UDP port 22443 on the agent. This means most should be considered medium- to high-speed WAN use cases. format. The encoder switch dynamically switches between either the JPG/PNG codec or the Blast Codec, and H.264, depending on the screen content type. Except under unique conditions, it is not possible to increase quality while limiting system resources. Display resource-intensive multimedia content in a window instead of full screen. This means that display content encoded and compressed using PNG alone can be restored to match the quality of the original content. 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. It is possible to configure the Blast External URL on the Unified Access Gateway appliance to use port sharing on TCP port 443 so that no additional ports need be opened on the front-end firewall. Visit these other VMware sites for additional resources and content. DecoderImageCacheSizeKB Introduced in Horizon 8 (2111).Set on the client. JpegQualityLow The lowest quality JPG/PNG will start with before building the screen to higher quality. VMware made the DPI setting on the client device leading and adjusts the remote desktop accordingly. Blast Extreme supports four codecs: JPG/PNG, H.264, HEVC (H.265), and the new Blast Codec. HTML5 multimedia redirection transfers this screen content to the client as HTML5 code instead of far less efficient display protocol traffic. It is better to leverage HTML5 multimedia redirection to optimize such use cases. To enable the new feature, you need to set this registry key on your VDI machine: Key: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\VMware, Inc.\VMware Blast\Config\EncoderSwitchEnabled. In other words, the settings do not directly enable the feature, such as forcing all connections to use H.264. How can i set the defaults for all my users on 16000 Hz? Problem is with second file, which is growing sometimes up to 15GB, then new files are created. You can increase the rate, up to 60 FPS, by using the Windows Registry setting. For more information see. After you apply the policy, the system stores the settings in the registry key HKLM\Software\Policies\VMware, Inc.\VMware Blast\config. Another important aspect to consider is the size of the monitor (or monitors) to be used, and their screen resolutions.

Let us help you become the hero of your department. EncoderH264YUV444 Enables or turns off support for High Color Accuracy for H.264. HEVC will not work with CPU encoding alone. 1 enabled in both directions 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. For Linux desktops: Horizon for Linux version 7.5 or later is required; Horizon for Linux version 7.10 or later is recommended. to identify the best quality at an acceptable level of bandwidth utilization. [VVCSessionManager] BlastSocketDataSockActivatedCb: Data Connection:UDP, [VVCSessionManager] BlastSocketDataSockActivatedCb: Data Connection:TCP. Applications requiring lossless reproduction of original screen content such as non-diagnostic medical imaging. The script will override the blast settings for users with an existing prefs.txt file without overriding the remaining settings. With the Horizon 2106 release, we also announced support for the NVIDIA Ampere A10 and A40 GPUs. It is especially good at reproducing intricate fonts and other screen content with fine details, including still images and low-motion 3D modeling used by design and engineering applications. Testing has shown this enables smooth 4K video playback without need for hardware GPUs. I'm searching for some settings to set retention/maximum log size/log level for this file. A TCP WebSocket connection is made on port 22443 between the client and the virtual desktop or RDSH server. EncoderAdaptiveEnabled Enables or turns off support for the VMware JPG/PNG codec. It also causes some streaming video to letterbox, which may impair user experience. The Blast Worker process ( VMBlastW.exe) captures the screen and handles everything within the session. Although RAM is rarely the bottleneck, monitor RAM to ensure it is not being over utilized by applications.

Before tuning Blast Extreme, it is critical to properly size and optimize the virtual desktops, physical desktops, Microsoft RDSH servers, and supporting infrastructure. What about frame rate? 1 enable upload and download Set up the VM with general settings, as follows, and then further configure according to the type of graphics acceleration you are using. RDP is working fine but not pcoip/blast because you might have not optimized these two protocols for this purpose.Increase video memory to 128MB on master image and recompose/push. The second key configurable component is the codec used to encode and decode the screen content transferred by Blast Extreme. The next section describes the workflow of connections made between the client and agent components. To observe this in action we can control the codec selection using the VMware Blast settings on the Horizon client. Question: 1. Important: Many of the optimizations available to the other codecs have not yet been developed for the Blast Codec, including the ability to set custom image qualities. While most of the Blast Extreme settings are included in the ADMX template, some are not, including those related to the Blast Codec and encoder switch. To verify operation, examine the logs. General settings include both Computer Configuration and User Configuration settings. Here you can create an account, or login with your existing Customer Connect / Partner Connect / Customer Connect ID. You can combine GPU with PCoIP and blast settings to adjust video performance, frame rate (frames per second), i mage quality level, based on your available . Once infrastructure resources and capacity have been verified, and the desktops and servers have been optimized, the performance of the display protocol can be tuned as necessary. Watch conversations with VMware experts on top-of-mind issues. Note: Different types of client devices support different features of Blast Extreme. 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 .
