Resolution Configuration for CP Conferences

The Resolution Configuration dialog box enables Collaboration Server administrators to
override the default video resolution decision matrix, effectively creating their own decision
matrix. The minimum threshold line rates at which endpoints are connected at the various
video resolutions can be optimized by adjusting the resolution sliders.
System resource usage is also affected by the Resolution Configuration settings. For more
information see "Video Resource Usage" on page
Rates and Resource Usage Summary" on page 4-6.
