Yes: Deselect all codecs and codec options (uncheck: H.264, Allow High Color Accuracy, and Allow High Efficiency Video Coding). . This means that display content encoded and compressed using PNG alone can be restored to match the quality of the original content. EUC Solutions Exchange on VMware CODE is the best place to find and share snippets. VNCRegionEncoder_Create: region encoder switch. Depending on the environment and design requirements, these external URLs can be configured in several different ways: Using multiple ports on a single address (Port Address Translation) Applications requiring lossless reproduction of original screen content such as non-diagnostic medical imaging. The Blast Codec was designed to be the ideal codec for these types of applications. 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. For this reason, HEVC in Blast Extreme requires that the ESXi hosts supporting the virtual desktops and RDSH servers have NVIDIA Tesla or newer GPUs to offload its encoding. There are some special considerations when supporting work-from-home and home-office-to-cloud use cases: The other common reason to tune display protocols is to increase quality. The log files are located in: :\ProgramData\VMware\VMware Blast\.

If Sound Card is not available in the Settings pane, click Add Device > Sound Card, then click Add. Audio is also enabled, but is not currently being used. When helping customers troubleshoot poorly performing infrastructures, VMware Professional Services routinely finds that the virtual desktops have not been sized properly and are consequently running out of critical resources such as virtual CPUs. See the faces behind the names of our Tech Zone content. With non-multimedia workloads, the Blast Codec uses the least bandwidth compared to all other codec options. VNCEncodeRegionNvEncGetHandle: region encoder NVIDIA NvEnc H264 using YUV 4:2:0 color space. Note that HDR is an optional capability of HEVC (High Efficiency Video Coding, H.265) and requires an NVIDIA hardware GPU. The next component to optimize is the Windows operating system. If UDP is enabled on the client, the Unified Access Gateway, and the agent (default), the client attempts to make a UDP connection to the agent via the Unified Access Gateway. Test the new Blast Codec unless this use-case is primarily in support of full motion video or high-speed motion graphics such as gaming. If users experience any of these issues, HCA can be enabled to improve quality while preserving H.264s multimedia efficiency. 4 If using Blast Secure Gateway 5 Not using Blast Secure Gateway 6 Standard encoded RMI 7 RMI over SSL 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. MaxBandwidthKbpsPerMegaPixelSlope The maximum bandwidth used to transfer screen contents per megapixel remoted, in kilobits per second. Added guidance on using Network Quality-of-Service (Qos) to prioritize Blast. The registry location to configure Blast Extreme is: HKEY_LOCAL_MACHINE\SOFTWARE\Vmware, Inc.\Vmware Blast\Config. Ability to use either the TCP or the UDP network transport. While typically supporting just a single user, most households do not yet have LAN-speed Internet connections (gigabit Ethernet). The fewer packets the display protocol has to transfer across the network, the fewer that will be affected by high latency. Note: for all settings in the following table, if the key is set to 1 support is enabled; if it is set to 0 support is turned off. For information about administrator settings, end-user settings, and various optimization strategies, see the VMware Blast Optimization Guide. The port used by the Blast Secure Gateway on the Unified Access Gateway can be customized (for example, it can use TCP 443). High Efficiency Video Coding (HEVC). General Settings for Virtual Machines The default setting of 6200 is geared towards efficiently supporting a medium-quality use case. : NVIDIA GPUs will also offload H.264 and HEVC encoding. VMware Blast: H. 264 Quality. This is due to the much higher graphical quality this hardware-enabled configuration provides.
