7 Imaging Considerations
PCoIP Technology’s imaging parameter settings
have a large impact on user experience and
bandwidth use.
Imaging Configuration
The Administrative Web Interface’s Image
webpage allows setting the preference during
network congestion:
• Lower-quality images at a higher frame rate
• Higher-quality images at a lower frame rate
Figure 7-1: Image Webpage
The Image webpage has two parameters:
Minimum Image Quality – allows balancing
between image quality and frame rate for
limited-bandwidth scenarios:
• Selecting towards Reduced allows higher
frame rates (and lower quality display) when
network bandwidth is constrained
• Selecting towards Perception-Free allows
higher image quality (and lower frame rates)
when network bandwidth is constrained
Note: When network bandwidth is not
constrained, PCoIP System maintains maximum
image quality regardless of this setting.
Note: Minimum Image Quality must be set less
than or equal to Maximum Initial Image Quality
(see below).
It is recommended to set Minimum Image
Quality to 40 to fully utilize PCoIP to balance
quality and frame rate.
Maximum Initial Image Quality - changes the
network bandwidth peaks a PCoIP Session
requires by limiting initial quality on the changed
regions of the image:
• Selecting towards Reduced reduces image
quality of content changes and reduces peak
bandwidth requirements
• Selecting towards Perception-Free increases
image quality of content changes and
increases peak bandwidth requirements
Note: The unchanged regions of the image
progressively build to lossless state regardless
of this setting.
Note: Maximum Initial Image Quality must be set
greater than or equal to Minimum Image Quality.
It is recommended to set Maximum Initial Image
Quality to 90 or lower to best utilize the available
network bandwidth.
