Therefore, images compressed using JPG cannot be decoded and restored to the same quality they had before compression. It may be a good idea to completely uninstall VMware Tools and re-install. With an internal connection, the client, the server, and the virtual desktop or RDSH server are all inside the corporate network. There is something for every experience level. Click OK to remove the IPSec rules. First introduced in Horizon 7.10, the Blast Codec is rapidly evolving but does not yet support all the optimizations and configuration options available to the other codecs. Clients 5.3 and later do not. For more information, see. The following updates were made to this guide. 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. Display communication protocols provide end users with a graphical interface to a remote desktop or published application. With the Horizon 2106 release, we also announced support for the NVIDIA Ampere A10 and A40 GPUs. If full-motion graphics must be supported, such as streaming video, use the encoder switch to dynamically switch between the Blast Codec or JPG/PNG and the H.264 codec. Ensure that ESXi hosts have sufficient resources, especially CPU. Find all of TechZone's available downloadable content here. If the UDP connection is successful, Blast assesses the networks condition to decide whether to use TCP or UDP for session traffic. And limiting frame rate for multimedia use cases such as streaming video simply impairs playback quality and user experience. On the client, this means near universal H.264 GPU decode support, because nearly all devices with graphics cards manufactured since 2013 have hardware H.264 decode support, including cell phones and most thin clients. This capability not only provides a better user experience but also reduces the resources required for display protocol encoding overall. If multimedia redirection (MMR) is enabled, this traffic uses TCP port 443 from the client to the Horizon Tunnel on the Unified Access Gateway. Welcome to VMware Digital Workspace Tech Zone, your fastest path to understanding, evaluating, and deploying VMware End User Computing products.

Because H.264 also provides good support for most Windows, Linux, and macOS applications, it is also the default Blast Extreme codec option. When client-drive redirection (CDR) is enabled by the administrator, this traffic goes through the Horizon Tunnel on the Unified Access Gateway appliance. Deselect all other codecs and codec options. 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). It also causes some screen content to letterbox, which may impair user experience. to identify the best quality at an acceptable level of bandwidth utilization. Same applications that are ideal for H.264 with HCA while offloading the encoding from the ESXi host CPUs to an NVIDIA GPU. There are several ways that these settings can be applied. Expanded the guidance on how to enable different codecs and verify the running configuration. For details about editing View Connection Server settings and security server settings, see the VMware Horizon View Administration documentation. Enable build-to-lossless mode if supporting a use case such as non-diagnostic medical imaging, which requires the display to be transferred without loss of quality. 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. And if Blast Extreme encounters problems making its initial connection over UDP, it will automatically switch and use TCP for the session instead. On the client side, you can configure which codec or codecs to use for encoding and decoding the screen content transferred by Blast Extreme. (Requires NVIDIA GPU), VNCRegionEncoder_Create: region encoder NVIDIA NvEnc HEVC. 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. Same applications as for the JPG/PNG codec and the H.264 with HCA codec.
