For details about editing View Connection Server settings and security server settings, see the VMware Horizon View Administration documentation. A codec is used to encode and decode the screen content transferred by Blast Extreme. By default, Blast Extreme is capped at 30 frames per second (FPS). This KB outlines the top trending cause associated with an intermittent external screen redirection issue with the Blast Protocol over Unified Access Gateway (UAG) To collect logs on a Mac, you can use the. The encoder switch ensures that the most efficient codec is dynamically used based on screen content. If the testing is not successful, use JPG/PNG. Figure 1: Choosing Blast Extreme in the Horizon Client Options. This can help determine the best architecture, understand the traffic flow, and network ports, and help in troubleshooting. For the following conditions, VMware recommends that you use TCP rather than UDP: For all other network conditions, VMware recommends that you use UDP for the best user experience. To observe this in action we can control the codec selection using the VMware Blast settings on the Horizon client. For details about the remote experience features, see Configuring Remote Desktop Features, in the guide Configuring Remote Desktop Features in VMware Horizon. This means the client resorts to CPU decoding, which can result in degraded performance on weak client hardware, particularly when using high-resolution monitors. For external connections, Blast Extreme can use the security certificate on the Unified Access Gateway appliance. 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. Webcam support in VMware Horizon View is a feature that has frequently been requested. The next section describes the workflow of connections made between the client and agent components. Although this strategy makes for reliable delivery, the process adds overhead. This means the encoder preserves all of the information related to color instead of sacrificing some to increase codec efficiency. However, it is important to note that building-to-lossless increases session bandwidth utilization because more display information is sent across the network. All TCP and UDP connections use TLS to encrypt communication. See the faces behind the names of our Tech Zone content. See. Demanding graphical applications commonly require more than two virtual CPUs, even with hardware GPU support. However, in testing it has been determined that only Intel GPUs support OpenGL applications in a remote session. 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. A TCP WebSocket connection is made on port 22443 between the client and the virtual desktop or RDSH server. Be certain to test any QoS configuration extensively to ensure not just proper performance for Blast Extreme, but that the configuration does not negatively impair other applications and services that the network must also support. HTML5 multimedia redirection transfers this screen content to the client as HTML5 code instead of far less efficient display protocol traffic. Horizon Cloud on Microsoft Azure Activity Path. 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). Another key Blast Extreme innovation is the encoder switch.
