• The Polycom HDX system supports up to eight sites in a multipoint call.
During calls that include more than four sites with Discussion or
Presentation mode selected, the Polycom HDX system displays the site
that is hosting the conference along with the last three sites where people
spoke.
• When the system that is streaming a multipoint call is also hosting the
conference, the stream displays the current speaker, no matter how
Multipoint Mode is configured.
To select video sources, use the Display Near Video, Display Far Video,
and Display Content settings on the Monitors screens.
Adjusting the Monitor’s Color Balance, Sharpness, and Brightness
In most cases, the monitor you connect to your system may be set to a
configuration that is appropriate for video conferencing applications.
Depending on your environment and model of monitor, however, the video
may exhibit one of these problems:
• Picture is too dark or too bright
• Colors appear faded
• Picture has too much of one color — for example, the picture may appear
greenish
• Picture has blocky or softened edge detail
If you notice any of these problems, adjust the monitor until the display seems
acceptable. Use the video diagnostics test as described in the following steps,
or purchase a calibration program DVD tool to help you fine-tune the display
settings.
Points to note about Discussion mode:
• To correctly display Discussion mode, you must select both Near and Far video
sources for Monitor 1.
• To correctly display Discussion mode for multipoint calls with three sites shown
on two monitors, you must select both Near and Far video sources for Monitor
1, and clear Far for Monitor 2.
• You cannot display Discussion mode on Monitor 2.
• For multipoint calls using MGC, disable Zoom People Video to Fit Screen in
order to properly display Discussion mode on a 16x9 monitor.
