Chapter 3-Video Protocols and Resolution Configuration for CP Conferencing

Polycom, Inc.

The Resolution Configuration dialog box enables RMX 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

 and "Default Minimum Threshold Line 

.

Continuous Presence requires an additional license. In the Resource Report and Resolution

will enable SD by default.
