Table 511. Horizon PCoIP Session Variables for the Keyboard
Setting Description
Disable sending CAD when users press
Ctrl+Alt+Del
When this policy is enabled, users must press Ctrl+Alt+Insert instead of
Ctrl+Alt+Del to send a Secure Aention Sequence (SAS) to the remote
desktop during a PCoIP session.
You might want to enable this seing if users become confused when
they press Ctrl+Alt+Del to lock the client endpoint and an SAS is sent to
both the host and the guest.
This seing applies to Horizon Agent only and has no eect on a client.
When this policy is not congured or is disabled, users can press Ctrl
+Alt+Del or Ctrl+Alt+Insert to send an SAS to the remote desktop.
Use alternate key for sending Secure
Attention Sequence
Species an alternate key, instead of the Insert key, for sending a Secure
Aention Sequence (SAS).
You can use this seing to preserve the Ctrl+Alt+Ins key sequence in
virtual machines that are launched from inside a remote desktop during
a PCoIP session.
For example, a user can launch a vSphere Client from inside a PCoIP
desktop and open a console on a virtual machine in vCenter Server. If
the Ctrl+Alt+Ins sequence is used inside the guest operating system on
the vCenter Server virtual machine, a Ctrl+Alt+Del SAS is sent to the
virtual machine. This seing allows the Ctrl+Alt+Alternate Key sequence
to send a Ctrl+Alt+Del SAS to the PCoIP desktop.
When this seing is enabled, you must select an alternate key from a
drop-down menu. You cannot enable the seing and leave the value
unspecied.
When this seing is disabled or not congured, the Ctrl+Alt+Ins key
sequence is used as the SAS.
This seing applies to Horizon Agent only and has no eect on a client.
PCoIP Build-to-Lossless Feature
You can congure the PCoIP display protocol to use an encoding approach called progressive build, or
build-to-lossless, which works to provide the optimal overall user experience even under constrained
network conditions. This feature is turned o by default.
The build-to-lossless feature provides a highly compressed initial image, called a lossy image, that is then
progressively built to a full lossless state. A lossless state means that the image appears with the full delity
intended.
On a LAN, PCoIP always displays text using lossless compression. If the build-to-lossless feature is turned
on, and if available bandwidth per session drops below 1Mbs, PCoIP initially displays a lossy text image
and rapidly builds the image to a lossless state. This approach allows the desktop to remain responsive and
display the best possible image during varying network conditions, providing an optimal experience for
users.
