PCoIP Zero Client and Host Administrator Guide (Issue 5)
Parameter Description
Minimum Image Quality Lets you compromise between image quality and frame rate when
network bandwidth is limited. Some use cases may require lower-
quality images at a higher frame rate while others need higher-
quality images at a lower frame rate.
In environments where the network bandwidth is constrained, move
the slider towards Reduced to allow higher frame rates. Move the
slider towards Perception-Free to allow for higher image quality.
When network bandwidth is not constrained, the PCoIP system
maintains perception-free quality regardless of the Minimum Image
Quality parameter.
Note: The Maximum Initial Image Quality must be greater than or
equal to the Minimum Image Quality.
Maximum Initial Image
Quality
Move the slider towards Reduced to reduce the network bandwidth
peaks caused by screen content changes, but produce lower quality
images. Move the slider towards Perception-Free to produce higher
quality images but also higher bandwidth peaks.
This parameter limits the initial quality on the first display frame of a
screen change. Unchanged regions of the image are built to a
lossless state regardless of this parameter.
Note: The Maximum Initial Image Quality must be greater than or
equal to the Minimum Image Quality.
Maximum Frame Rate The maximum frame rate helps you manage multiple PCoIPsessions
over a single network link. This setting determines the limit that your
users can reach. Set this field to 0 to set no frame limit. If you set a
value, a single user is limited to that value. This helps to control the
user experience for all your users.
Note: This setting does not work in PCoIP sessions with VMware
View virtual desktops running release 5.0 or earlier.
Disable Build to
Lossless
Leave this field unchecked to retain the PCoIP protocol's build-to-
lossless feature, where images continue to be refined in the
background until they reach a fully lossless state (i.e., identical pixel-
for-pixel rendering when compared to the host image source). This is
the default (recommended) setting.
Warning: Turning on the Disable Build to Lossless field will
degrade the image presented to the user by the zero client. Do not
turn on this field unless it has been determined by the administrator
of the zero client that users do not require optimal image quality to
perform critical functions. It is the sole responsibility of the zero client
administrator to make this determination.
If you do choose to turn on this field, the PCoIP protocol rapidly
builds the client image to a high quality image that may be
perceptually lossless, but is not a fully lossless state. This may
provide some bandwidth savings, but is not recommended for use
cases that require images and desktop content to be truly lossless.
If you have any questions about this field setting, contact Teradici
support.
Note: This setting does not work in PCoIP sessions with VMware
View virtual desktops running release 5.0 or earlier.
