The 4:2:0 sample rate can result in color washout as well as text or image fuzziness when using some applications (for example, CAD) or some color combinations. Navigate to Virtual Machine > Settings (Fusion) or VM > Settings (Workstation). The second key configurable component is the codec used to encode and decode the screen content transferred by Blast Extreme. 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. See, Worksheet for Creating an Instant-Clone Desktop Pool, You can also configure the remote display protocol at the RDSH server farm level. Moving to the cloud? Blast can deliver a decent experience with default settings, however, some networks and scenarios need additional tuning. With an internal tunneled connection, the client, the server, and the virtual desktop or RDSH server are all also inside the corporate network, but the clients might be on a different subnet from that of the virtual desktops or RDSH servers (where the agent is installed), and you do not want to open ports between the clients and agents directly. Do not use client-drive redirection unless absolutely required. Click the View All button for the full list. This connection is from the client to UDP port 8443 on the Unified Access Gateway. . Figure 4: External Connection from Client to Agent Through the Unified Access Gateway. 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). 2 enable file upload only Because this Dynamic Environment Manager functionality needs to evolve to match advances in Blast Extreme, the author of this guide recommends not using the Blast policies included with Dynamic Environment Manager until covered in a future guide release.

Horizon ADMX Template Files - docs.vmware.com This KB outlines the top trending cause associated with an intermittent external screen redirection issue with the Blast Protocol over Unified Access Gateway (UAG) VNCSERVER-WIN32: ***Setting topology completed by Nvidia Display***. Find all of TechZone's available downloadable content here. Although this results in a similar reduction in the network bandwidth required, it uses substantially more CPU processing power to encode and decode. On the Security Server, run the downloaded VMware-Horizon-Connection-Server-x86_64-7.13.2.exe. This guide is intended for IT administrators and implementors who want to provide end users with the best possible remote display experience. Note: This parameter does not impact the bandwidth of other services such as audio and file transfer, which are unrelated to transfer of the screen.
VMware Horizon 2206 release enhances security, end-user experience, and :\ProgramData\VMware\VMware Blast\. Deploying Hardware-Accelerated Graphics with VMware Horizon Let us help you learn how to use it. Fix the network if packet loss is greater than 5 percent. If the primary use-case is full motion video or high-speed motion graphics such as gaming, use the H.264, H.264 with High Color Accuracy or High Efficiency Video Coding (codecs), offloaded to an NVIDIA Tesla or newer GPU. 4 If using Blast Secure Gateway 5 Not using Blast Secure Gateway 6 Standard encoded RMI 7 RMI over SSL Become a desktop virtualization hero with our curated activity path. 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. More information about the admin settings is provided in the next section of this chapter. Type: REG_SZ. For mixed workloads, use the encoder switch to dynamically switch between the new Blast Codec or JPG/PNG and H.264 codecs. For information about configuring this setting, see the guides Setting Up Virtual Desktops in Horizon, Setting Up Published Desktops and Applications in Horizon, and Administering Cloud Pod Architecture in Horizon, available from the VMware Horizon Documentation site. WANs typically have just a fraction of the bandwidth that is available on local area networks (LANs). If the file does not exist, it will create it with the blast settings already enabled. The authors wish to thank the following people for their contributions to this paper: To comment on this paper, contact VMware End-User-Computing Technical Marketing at euc_tech_content_feedback@vmware.com. For more information, see. Use of a solid color with no image or pattern is recommended. This can result in H.264 being used for one display and JPG/PNG or the Blast Codec being used for another simultaneously. 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. At Tech Zone, our mission is to provide the resources you need, wherever you are in your digital workspace journey. Screen 0/1 @ Resolution: 3840 x 2160. 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 (the lowest currently supported setting). Blast Extreme is included with VMware Horizon, the latest generation of VMware desktop virtualization and remote application-delivery software. MainApp::OnEncoderConfigChanged: Encoder config changed: EncoderBuildToPNG = 1. On the client side, you can configure which codec or codecs to use for encoding and decoding the screen content transferred by Blast Extreme. In this mode, the codec is able to support applications that require the display protocol to be lossless, ensuring nothing is lost in transmission. VNCEncodeRegionNvEncGetHandle: region encoder NVIDIA NvEnc H264 using YUV 4:4:4 color space. Updated to cover Horizon 8 (2111) and Horizon Cloud November 2021. 10 Tips for Optimizing VMware Horizon VDI's Blast Extreme Protocol This will force H.264 to start at higher quality and prevent it from expending bandwidth to send initial low-quality screens. Ensure that ESXi hosts have sufficient resources, especially CPU. 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. If UDP is not enabled or is blocked, the initial TCP connection (Step 3) is used instead. : Because port sharing incurs some performance overhead on Unified Access Gateway, port sharing is not the preferred configuration. Same applications that are ideal for H.264 with HCA while offloading the encoding from the ESXi host CPUs to an NVIDIA GPU. Click the View All button for the full list. (which like all VMware flings, is not officially supported). Typical productivity applications such as Microsoft Office, plus those requiring support for fine details and higher still image quality. However, compared to other codecs, H.264 requires more processing power to perform its encoding and decoding operations. Begin your journey leveraging cloud-based services for desktop environments. Use cases of this caliber nearly always require hardware GPUs to provide the necessary graphics capabilities and acceleration. The following updates were made to this guide. 2 enabled client to server only VMware Blast Extreme GPO Registry Keys - FROGGYJ This ensures that all systems deployed from these templates are configured properly for Blast Extreme. Horizon 7 and Horizon 8 - Kemp Support 2. The settings allow you to manage the maximum bandwidth that any one user can consume. Various components of a display protocol can be configured to address the different types of screen content and differing network speeds that end users are likely to encounter. This configuration is ideal for digital photography, design and video production. This means the encoder preserves all of the information related to color instead of sacrificing some to increase codec efficiency. If users are experiencing poor text or image clarity in certain applications with H.264 alone, Blast Extreme can be configured to use High Color Accuracy (HCA). Deep Dive into VMware Horizon Blast Extreme Adaptive Transport, VMware Horizon Blast Extreme Acceleration with NVIDIA GRID, 3D Graphics like never before with VMware Horizon and NVIDIA T4 GPUs, Frank Anderson, EUC Architect, EUC Technical Marketing, VMware, , EUC Architect, EUC Technical Marketing, VMware, Ramu Panayappan, Director, Virtual Workspace R&D, VMware, Mike Oliver, Staff Engineer, Virtual Workspace R&D, VMware, Salil Kanitkar, Senior Member of the Technical Staff, Virtual Workspace R&D, VMware, Matt Coppinger, Director, Technical Marketing and Enablement, EUC Technical Marketing, VMware. 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. SwitchEnc: 1 Screen 1 switching to h264 4:2:0 encoder. Deselect all other codecs and codec options. Caroline Arakelian is a Senior Technical Marketing Manager, End-User-Computing Technical Marketing, VMware. The Horizon Client authenticates to a Connection Server through the Unified Access Gateway. TCP 443 is used between the client and the Unified Access Gateway. Other codec options can only be enabled by administrators and also require a corresponding Horizon Client setting. Use our product forums to engage with the community. The following settings are specifically helpful for handling low-bandwidth conditions: Note that these minimum and maximum bandwidth settings are best effort, not hard limits. The goal is to configure QoS to prioritize Blast Extreme above general network traffic, but below the few applications that are even more sensitive to delay. Utilize this tool to get you part of the way there. If UDP is not enabled or is blocked, the initial TCP connection (Step 3) is used instead. 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 following tuning recommendations apply to all WAN conditions. I ended up writing a logon script to solve the problem until VMware fixes it. While most of our environment is running PCoIP, we have also tested with BLAST. Note: For more information about internal client connections, see Network Ports in VMware Horizon. Easily manage VM Profile settings across images. HTML5 multimedia redirection transfers this screen content to the client as HTML5 code instead of far less efficient display protocol traffic. Lower power consumption means longer battery life. It may be a good idea to completely uninstall VMware Tools and re-install. To find out which Blast Extreme settings are available for a specific client platform, see the Horizon Client user guide for that platform, available from the VMware Horizon Client Documentation page. Understand and Troubleshoot Horizon Connections | VMware End-users access to their personalized virtual desktops or remote applications from company laptops, their home PCs, thin client devices, Macs, tablets, or smartphones. NVIDIA H.264 with HighColorAccuracy Fortunately, VMware has developed a free tool to optimize Windows desktops and servers. How to troubleshoot a VMware Horizon black screen H.264 applications that require higher color quality or that exhibit lack of clarity with H.264 alone. General Settings for Virtual Machines Deselect all other codecs and codec options. Use HTML5 multimedia redirection if resource-intensive web-browser-based content such as YouTube or eLearning streaming video must be supported at high screen resolutions without NVIDIA GPUs.
