Table 514. 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 Attention Sequence (SAS) to the remote desktop
during a PCoIP session.
You might want to enable this setting 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 setting applies to Horizon Agent only and has no effect on a client.
When this policy is not configured 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
Specifies an alternate key, instead of the Insert key, for sending a Secure
Attention Sequence (SAS).
You can use this setting 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 setting
allows the Ctrl+Alt+Alternate Key sequence to send a Ctrl+Alt+Del SAS to the
PCoIP desktop.
When this setting is enabled, you must select an alternate key from a drop-
down menu. You cannot enable the setting and leave the value unspecified.
When this setting is disabled or not configured, the Ctrl+Alt+Ins key sequence
is used as the SAS.
This setting applies to Horizon Agent only and has no effect on a client.
PCoIP Build-to-Lossless Feature
You can configure 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 off 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
fidelity 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.
