Why it is only showing this low settings? All three howeverNVIDIA, AMD, and Intelare able to support Microsoft DirectX. Deselect all other codecs and codec options. The Connection Server returns the connection information for the virtual desktop or RDSH server that provides remote applications (on TCP port 443). If desired, the traffic between the Unified Access Gateway and Horizon Agent can be configured to use a separate port (TCP 9427). Note: Dynamic Environment Manager also provides optimization templates for Blast Extreme. 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. Optimize the desktops and RDSH servers using the VMware Operating System Optimization Tool.
Setting Frame Rates and Resolution for Real-Time Audio-Video - VMware In testing with a single 4K display, viewing a typical YouTube video in standard windowed mode used 53 percent less bandwidth and 23 percent less virtual desktop CPU than watching the same video full-screen. Tunneling traffic through the Connection Server allows for ports to be open between the Connection Server and the client, and between the Connection Server and the agent, but not between the client and the agent. VMware Blast: H. 264 Quality. JPG/PNG can also be configured to use build-to-lossless mode. If you are using Horizon Client for macOS 5.0 or later, this Horizon Collector functionality is included in Horizon Client. How can i set the defaults for all my users on 16000 Hz? High Efficiency Video Coding, or HEVC for short, is also known as H.265 and is the industry successor to H.264. This means that some of the original image data is discarded (lost) as part of the compression process. 2 enabled client to server only When using Blast Extreme, Unified Access Gateway can be used to bridge between IPv6 VMware Horizon Clients and an IPv4 backend and agents. As its name implies, the JPG/PNG codec leverages two image formats, JPG and PNG, to encode and decode display content. USB redirection traffic can also be side-channeled in the Blast Extreme port between the Unified Access Gateway and agent. Update for VMware Horizon 7 versions 7.1 and 7.2. Some tradeoff in system configuration, supportable applications, and user experience is to be expected. In testing, UDP has been shown to handle packet loss better than TCP in most situations. 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. VMware Blast performance and end-user experience acceleration Blast is now the new default.

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. Same applications as for the Blast Codec and the H.264 codec. 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. The second key configurable component is the codec used to encode and decode the screen content transferred by Blast Extreme. General settings include proxy options, time zone forwarding, multimedia acceleration, and other display settings. If users experience any of these issues, HCA can be enabled to improve quality while preserving H.264s multimedia efficiency. This capability not only provides a better user experience but also reduces the resources required for display protocol encoding overall. Typical Microsoft Office use, for example, results in a very low display protocol frame rate. 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. HTML5 multimedia redirection transfers this screen content to the client as HTML5 code instead of far less efficient display protocol traffic. Introduced in Horizon 8 (2106): Enable support for High Dynamic Range (HDR) color. With an internal connection, the client, the server, and the virtual desktop or RDSH server are all inside the corporate network. 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. Load Balancing for VMware Horizon (2146312) | VMware KB Figure 3: Group Policy Settings for Blast Extreme. For mixed workloads, use the encoder switch to dynamically switch between the new Blast Codec or JPG/PNG and H.264 codecs. Testing has shown this reduces the bandwidth required to support such content by up to 80 percent. 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.
