If the highest quality of video that “user1” can send is 180p, based on PC hardware and available bandwidth, then
180p is the highest video resolution that a remote site “user2” can receive. This resolution refers to the video
resolution after the decoding process for “user2”. If the source of the incoming video is 180p, it is impossible for the
decoder on the “user2” PC to output any resolutions higher than 180p.

During application sharing, desktop sharing, streaming video sharing, and meeting manager sharing, 720p video
(HD) is disabled.
A quad-core PC or Mac can send and receive 720p (HD) resolution; a dual-core PC or Mac can receive only 720p
(HD) in multipoint meetings (includes three or more participants).
Because of network congestion or client machine use, the video stream may wait to be sent or received. During
this time you may have a visible, small-circle icon in the middle of your main video window; it will disappear as
soon as the video stream becomes available.
The log files can help administrators and support teams to better understand and troubleshoot possible client
software problems. Location of the log files is shown Table 19.
