A Windows Registry value also needs to be set to 1 on the Client under HKLM\SOFTWARE\VMware, Inc.\Vmware VDM\Client\AllowClientHDR to enable HDR. With Horizon 7 version 7.12, support for using Blast Extreme with physical desktop machines running Windows 10 versions 1903 and later was added. VMware Blast Extreme Group Policy Settings - Bits and Bytes Feature parity with the VMware PCoIP display protocol. 2 When RDP protocol is tunneled through the Connection Server or Security Server. Screen 0/1 @ Resolution: 3840 x 2160. If USB redirection is enabled, this traffic, this traffic uses TCP port 443 from the client to the Horizon Tunnel on the Unified Access Gateway. (Requires NVIDIA GPU), VNCRegionEncoder_Create: region encoder NVIDIA NvEnc HEVC. USB redirection traffic can also be side-channeled in the Blast Extreme port between the Unified Access Gateway and agent. They are designed to have something for people of every experience level. HCA turns off 4:2:0 chroma subsampling, providing a 4:4:4 sample rate instead. 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. These settings are used to configure the address at which clients can reach the specific server when tunneling is in use. Diagrams show which ports are used at which locations, and the numbered lists that follow the diagrams show what is happening at each connection. Like HEVC, the encoding for H.264 and H.264 with HCA can be offloaded to NVIDIA GPUs installed in the ESXi hosts. 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. Deploy virtual desktops and RDSH servers on fast virtual disks (all-flash or flash-optimized). Microsoft Teams Optimization with VMware Horizon | VMware Instructions for configuring all of the Blast Extreme codec options are provided in the next chapter, How to Configure Blast Extreme. 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. EncoderH264YUV444 Enables or turns off support for High Color Accuracy for H.264. Display communication protocols provide end users with a graphical interface to a remote desktop or published application. 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. SwitchEnc: 1 Screen 1 switching to h264 4:2:0 encoder. Support full-motion video at 4K display resolution or above without HTML5 redirection. VMware Blast Extreme uses VMware client-side components, installed with VMware Horizon Client, as well as agent-side components, installed on virtual desktops, physical desktops, and RDSH servers that host published applications and desktops. Using Horizon to Access Physical Windows Machines | VMware Get all the Tech Zone demos in one place. TLS version and encryption defaults are routinely updated to reflect current best practices. The Horizon Performance Tracker does not currently display the codec currently being used per screen by the encoder switch. And if Blast Extreme encounters problems making its initial connection over UDP, it will automatically switch and use TCP for the session instead. The default setting of 6200 is geared towards efficiently supporting a medium-quality use case. The Connection Server returns connection information for the virtual desktop or RDSH server that provides remote applications (on TCP port 443). 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. In this file, add the single line: RemoteDisplay.allowClientBlastCodec = TRUE. 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). If you use a Unified Access Gateway virtual appliance for connections from outside the corporate network, by default the connection uses TCP port 8443 and optionally UDP port 8443. Navigate to Computer Configuration > Administrative Templates > VMware View Agent Configuration > VMware HTML5 Features > VMware WebRTC Redirection Features > Enable Media Optimization for Microsoft Teams. Enable High Color Accuracy (HCA) for H.264 if supporting an H.264 preferred use case that has exhibited display fuzziness, lack of font or image sharpness, or problems with color reproduction. Desktop wallpaper unnecessarily expends both CPU resources to encode and network bandwidth to transfer. 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. Click the View All button for the full list. Added information about OpenGL and DirectX compatibility with hardware GPUs in remoted physical PCs. The port used by the Blast Secure Gateway on the Unified Access Gateway can be customized (for example, it can use TCP 443). We have many more paths than are shown here. Streaming video, for example, may freeze for a moment or pixelate briefly, but otherwise continue playing. Update for VMware Horizon 7 version 7.10. 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. They are downloaded as part of the VMware-Horizon-Extras-Bundle. Begin your journey leveraging cloud-based services for desktop environments. Another important aspect to consider is the size of the monitor (or monitors) to be used, and their screen resolutions. 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. Fortunately, Blast Extreme can be tuned to handle all of these situations. These pages help you understand the breadth of our most popular products. Contains entries that tell you whether UDP or TCP is being used. Testing has revealed this reduces desktop and per-user RDSH server CPU utilization by up to 60 percent and per-user session bandwidth by up to 80 percent. Client-drive redirection traffic uses TCP 9427. or you can specify that users can choose the protocol. Be certain to test key applications and multimedia content before widespread deployment. Deselect all other codecs and codec options. NVIDIA Ampere A10 and A40 GPUs. . For more information see Configuring HTML5 Multimedia Redirectionin Configuring Remote Desktop Features in Horizon 7. If multimedia redirection (MMR) is enabled, this traffic uses TCP port 9427 between the client and agent. 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. However, compared to other codecs, H.264 requires more processing power to perform its encoding and decoding operations. Use a single monitor with the lowest screen resolution supported by the use case. I'm searching for some settings to set retention/maximum log size/log level for this file. The Horizon Performance Tracker is an option that can be selected during the Horizon Agent installation on the virtual desktop, physical desktop, or RDSH server. When using Blast Extreme, Unified Access Gateway can be used to bridge between IPv6 VMware Horizon Clients and an IPv4 backend and agents. 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. 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. Visit these other VMware sites for additional resources and content. 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). Use cases of this caliber nearly always require hardware GPUs to provide the necessary graphics capabilities and acceleration.

EncoderNvidiaH264Enabled Enables or turns off support for offloading H.264 encoding to NVIDIA GPUs installed in the ESXi hosts. NVIDIA and AMD GPUs are not able to support OpenGL due to a limitation of their video drivers. HDR: Relative Brightness of the Paperwhite Level. Consider using HCA for H.264 with the encoder switch to dynamically match the highest-quality H.264 configuration with the Blast Codec or JPG/PNG. This means that some of the original image data is discarded (lost) as part of the compression process. H.264, the most commonly used codec in the world, was designed specifically to support entertainment content and is known for its use in encoding Blu-ray movies. This guide provides a technical description of the Blast Extreme display protocol, including its benefits, limitations, and deployment options, for administrators who are considering using Blast Extreme in their organization today. These optimizations directly reduce both CPU and network bandwidth. Note: At this point, the VMware Blast service on the agent side (Horizon Agent on the virtual desktop or RDSH server) proxies the incoming connection. Reducing network bandwidth is key to enabling support for all adverse network conditions. Except under unique conditions, it is not possible to increase quality while limiting system resources. Although it has more of an impact on multimedia and video gaming, experiment with different values, up to the maximum of. 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 Troubleshooting Display Issues with the Horizon Blast Protocol (90139) When you have created the registry key, re-initiate the connection to your VDI machine. 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. The following tuning options are recommended to increase display protocol quality for all use cases and applications. It is important to recognize, however, that no display protocol can provide a perfect LAN experience over typical WANs. If USB redirection is enabled, this traffic uses TCP 32111 between the client and agent. Note that this guidance does not include Metropolitan Area Networks (MANs) or similar LANs over long distance, which typically have as much, if not more, bandwidth than common user LANs. 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. For a detailed list of Blast Extreme features, see the VMware Blast Extreme topic in the VMware Horizon Architecture Planning guide. 2. If you're experiencing display driver issues (such as a blank screen), before re-installing VMware Tools try forcibly removing the display driver. With zero attack surface, unpublished API, and encrypted data Wyse ThinOS is virus and malware resistant. Note: Dynamic Environment Manager also provides optimization templates for Blast Extreme. Offloading the display protocol encoding is enabled by default but can also be turned off if the GPUs must be dedicated to supporting other tasks. This KB outlines the top trending cause associated with an intermittent external screen redirection issue with the Blast Protocol over Unified Access Gateway (UAG) More than 8 virtual CPUs might be required to support the most demanding use cases, especially video gaming, even with NVIDIA hardware GPUs. The following updates were made to this guide. Contains entries that tell you whether JPG/PNG or the H.264 coded is being used. Flash redirection causes the client to download and execute Flash content instead of rendering it in the virtual desktop and sending it across the WAN. UdpEnabled Enables or turns off support for the UDP transport protocol. 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. However, some use cases and situations require additional tuning, especially for wide area networks (WANs). 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.
