Determines whether audio information played on the View desktop is
redirected. Select one of the following settings:
Disable Audio
Audio is disabled.

Support)
Audio plays within the View desktop. This setting
requires a shared USB audio device to provide
sound on the client.
Redirect to
client
Audio is redirected to the client. This is the default
mode.
This setting applies only to RDP audio. Audio that is redirected through
MMR plays in the client.
Audio capture redirection
Determines whether the default audio input device is redirected from the
client to the remote session. When this setting is enabled, the audio
recording device on the client appears in the View desktop and can record
audio input.
The default setting is disabled.
Bitmap cache file size in unit for
number bpp bitmaps
Specifies the size of the bitmap cache, in kilobytes or megabytes, to use
for specific bits per pixel (bpp) bitmap color settings.
Separate versions of this setting are provided for the following unit and
bpp combinations:
n
KB/8bpp

MB/8bpp
n
MB/16bpp
n
MB/24bpp
n
MB/32bpp
Bitmap caching
Determines whether remote bitmaps are cached on the local computer.
Cache persistence active
Determines whether persistent bitmap caching is used (active). Persistent
bitmap caching can improve performance, but it requires additional disk
space.

Specifies the color depth of the View desktop. Select one of the available
settings:
n
8 bit
n
15 bit
n
16 bit
n
24 bit
n

For 24-bit Windows XP systems, you must enable the Limit Maximum
Color Depth policy in Computer Configuration > Administrative
Templates > Windows Components > Terminal Services and set it to 24
bits.
Cursor shadow
Determines whether a shadow appears under the cursor on the View
desktop.
Desktop background
Determines whether the desktop background appears when clients
connect to a View desktop.
Desktop composition
(Windows Vista or later) Determines whether desktop composition is
enabled on the View desktop.
When desktop composition is enabled, individual windows no longer
draw directly to the screen or primary display device as they did in
previous versions of Microsoft Windows. Instead, drawing is redirected
to off-screen surfaces in video memory, which are then rendered into a
desktop image and presented on the display.
