Setting Description
Configure PCoIP event log verbosity
Sets the PCoIP event log verbosity. The values range from 0 (least
verbose) to 3 (most verbose).
When this setting is enabled, you can set the verbosity level from 0 to 3.
When the setting is not configured or disabled, the default event log
verbosity level is 2.
When this setting is modified during an active PCoIP session, the new
setting takes effect immediately.
Configure PCoIP image quality levels
Controls how PCoIP renders images during periods of network
congestion. The Minimum Image Quality, Maximum Initial Image
Quality, and Maximum Frame Rate values interoperate to provide fine
control in network-bandwidth constrained environments.
Use the Minimum Image Quality value to balance image quality and
frame rate for limited-bandwidth scenarios. You can specify a value
between 30 and 100. The default value is 40. A lower value allows
higher frame-rates, but with a potentially lower quality display. A
higher value provides higher image quality, but with potentially lower
frame rates when network bandwidth is constrained. When network
bandwidth is not constrained, PCoIP maintains maximum quality
regardless of this value.
Use the Maximum Initial Image Quality value to reduce the network
bandwidth peaks required by PCoIP by limiting the initial quality of the
changed regions of the display image. You can specify a value between
30 and 100. The default value is 80. A lower value reduces the image
quality of content changes and decreases peak bandwidth requirements.
A higher value increases the image quality of content changes and
increases peak bandwidth requirements. Unchanged regions of the
image progressively build to a lossless (perfect) quality regardless of this
value. A value of 80 or lower best utilizes the available bandwidth.
The Minimum Image Quality value cannot exceed the Maximum
Initial Image Quality value.
Use the Maximum Frame Rate value to manage the average bandwidth
consumed per user by limiting the number of screen updates per
second. You can specify a value between 1 and 120 frames per second.
The default value is 30. A higher value can use more bandwidth but
provides less jitter, which allows smoother transitions in changing
images such as video. A lower value uses less bandwidth but results in
more jitter.
These image quality values apply to the soft host only and have no
effect on a soft client.
When this setting is disabled or not configured, the default values are
used.
When this setting is modified during an active PCoIP session, the new
setting takes effect immediately.
