PDF

Upgrade Horizon package to version 4.8

In ThinOS version 8.6, you can upgrade the thin client from Horizon version 4.6 to 4.8. VMware Horizon Virtualization Pack for Skype for Business is supported from this release onwards.

Horizon Client version 4.8 and Agent version 7.5 Virtualization Pack for Skype for Business are not compatible with older Horizon Client and Agent releases. If you use Horizon Client 4.8 or later and Horizon Agent 7.5 and later with older Client and Agent releases, then the fallback mode will be enabled on Skype for Business calls. For more information about the Compatibility of Horizon Virtualization Pack for SFB Components​, see kb.vmware.com/s/.

NOTE:
  • If you are upgrading your previous ThinOS client version to 8.6, you must ensure that the Horizon server or agent version is updated to support the Horizon client version 4.8. For information about interoperability matrices for client and server/agent version compatibility, see https://www.vmware.com/resources/compatibility/sim/interop_matrix.
  • ThinOS supports the hardware cursor in the VMware Blast session. By default, the hardware cursor is disabled. You must use the INI parameter to enable the hardware cursor. For more information about enabling the hardware cursor using the INI parameter, see the Dell Wyse ThinOS Version 8.6 INI Reference Guide at www.dell.com/support.
Limitations
  • ThinOS supports up to four 4K displays with limited performance in the Horizon Blast session. Due to low performance, Dell does not recommend using four displays with 4K resolution when H264 is enabled.
  • Vertical Synchronization does not work in Blast session with four 4K resolution.
  • Video performance is low whe you play a video in Blast session with 4K resolution.
  • ThinOS supports audio device USB redirection. However, Dell does not recommend using audio device USB direction due to low audio quality.
