Resolution Configuration dialog box.
The administrator can select one of the following Maximum
Resolution options:
• Auto (default) - The Maximum Resolution remains as selected in
the Resolution Configuration dialog box.

Maximum Resolution settings can be monitored in the Profile

Notes:
The Resolution field in the New Participant - Advanced dialog box
allows Maximum Resolution to be further limited per participant
endpoint.
The Maximum Resolution settings for conferences and participants
cannot be changed during an ongoing conference.
Video Clarity™ When enabled (default), Video Clarity applies video enhancing
algorithms to incoming video streams of resolutions up to and
including SD. Clearer images with sharper edges and higher contrast
are sent back to all endpoints at the highest possible resolution
supported by each endpoint.
All layouts, including 1x1, are supported.
Note: Video Clarity is enabled only when Video Quality is set to
Sharpness (default setting) and is disabled when Video Quality is set
to Motion.
Video Clarity can only be enabled for Continuous Presence
conferences in MPM+ and MPMx Card Configuration Mode.
Auto Brightness Auto Brightness detects and automatically adjusts the brightness of
video windows that are dimmer than other video windows in the
conference layout.
• Auto Brightness is supported with MPM+ and MPMx cards only.
• Auto Brightness only increases brightness and does not darken
video windows.
• Auto Brightness is selected by default.
• Auto Brightness cannot be selected and deselected during an
ongoing conference.
Default: On
Note: When Auto Brightness is enabled, color changes may be
observed in computer-based VGA Content sent by HDX endpoints
through the People video channel.
