using that profile will not be able to select Best Color. However, they could select a lower
color depth such as Gray Scale/Best Compression.
If you enable Allow users to override this setting, or if no profile is assigned to the target
device, users may specify the color depth using Video Viewer menu commands. See Video
commands on page 1.
Video scaling
The video scaling setting (View - Scaling) indicates the Video Viewer window resolution. You
may choose absolute values, auto scale or full scale.
When autoscaling is enabled, the DSView software will automatically adjust the display if the
window size changes during a session. When a user accesses a channel using sharing, the
display will be adjusted to match the input resolution selected by the primary user of that
channel. This will prevent the primary user’s display from being affected. If the target device
resolution changes any time during a session, the display will be adjusted automatically.
When full scaling is enabled, the display window is sized to match the resolution of the server
being viewed.
If users are allowed to override this profile setting, you may also control whether they may
select a value higher than the profile setting. For example, when this control is enabled, if the
video scaling setting in the profile is 768 x 576, users on a target device using that profile will
not be able to select 1024 x 768. However, they could select a lower resolution such as 640 x
480.
NOTE: Wide screen format absolute values are listed in the scaling menu, but may not be supported on all
appliances. If a value is not supported, it is disabled or hidden.
If you enable Allow users to override this setting, or if no profile is assigned to the target
device, users may specify the video scaling using Video Viewer menu commands. See Video
commands on page 303.
Background refresh
The background refresh setting enables or disables background refresh.
When background refresh is enabled, a small portion of video data is constantly sent by the
KVM switch to background refresh the Video Viewer window. When background refresh is
disabled, the Video Viewer window is updated by the switch only when it determines that the
target device video image has changed.
NOTE: This option is not available if the switch does not support background refresh or if the DSR Remote
Operations software is being used to connect to the DSR switch viewing the target device. See DSR Remote
Operations Software on page 1.
