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/article/54773.
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.
VMware Horizon Virtualization Pack for Skype for Business
The VMware Horizon Virtualization Pack for Skype for Business enables you to use Skype for Business in a VMware Horizon
desktop. Microsoft Skype for Business is a unified communications platform that delivers an optimized user experience for online
messaging, audio, and video calling and so on.
ThinOS supports VMware Horizon Virtualization Pack for Skype for Business in a Blast session. PCoIP and RDP protocols do not
support this feature.
NOTE:
● For information about configuring Skype for Business, and Optimized and fallback modes in Skype for Business, see the
Dell Wyse ThinOS Version 8.6 Administrator's Guide at www.dell.com/support.
● For information about the Horizon Agent installation, see the Setting Up Virtual Desktops in Horizon 7 document at
docs.vmware.com.
NOTE: Horizon Client 4.8 or later and Horizon Agent 7.5 and later are not compatible with older Client and Agent releases.
Due to this limitation, when you use the Horizon Client 4.8 and Horizon Agent 7.5 with older client and agent releases,
Skype for Business calls run in fallback mode and calls are not optimized. Ensure that you review the compatibility matrix of
Horizon Virtualization Pack for SFB components at kb.vmware.com/s/article/54773.
