Although RAM is rarely the bottleneck, monitor RAM to ensure it is not being over utilized by applications. Yes: Deselect all codecs and codec options (uncheck: H.264, Allow High Color Accuracy, and Allow High Efficiency Video Coding). Blast Extreme supports two transport protocols to carry the display traffic between clients and the Horizon infrastructure: TCP (Transmission Control Protocol) and UDP (User Datagram Protocol). Horizon with Blast 3D and Blast Performance - VMware Use UDP unless the traffic must pass through a UDP-hostile network device such as a TCP-based SSL VPN. The Blast Codec will continue to evolve. See Enabling the USB Over Session Enhancement SDK Feature. For external connections, Blast Extreme can use the security certificate on the Unified Access Gateway appliance. 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. Horizon Client (4.7): Forcing settings by GPO - VMware Yes: Select Allow High Efficiency Video Coding. A stated goal in the VMware Horizon documentation is "to provide an excellent out-of-the-box configuration for most local area network (LAN) use cases, negating the need to perform complex tuning or learn hundreds of policy settings." VMware notes that "some use cases and situations require additional tuning, especially for wide area networks . Testing has shown this enables smooth 4K video playback without need for hardware GPUs. Update for VMware Horizon 7 versions 7.1 and 7.2. This means the encoder preserves all of the information related to color instead of sacrificing some to increase codec efficiency. However, because H.265 requires substantially more processing power than H.264 to encode and decode, the ESXi hosts for desktops and server farms must have NVIDIA Tesla GPUs to offload encoding. Use a single monitor with the lowest screen resolution supported by the use case. In the client VMware Blast settings, Allow High Efficiency Video Decoding (HEVC) and Allow High Dynamic Range Decoding (HDR) needs to be turned on. Click the View All button for the full list. 1 In VMware Horizon, when using PCoIP Secure Gateway on the Connection Server or Security Server.
