Table 3‑6. Horizon Client Configuration Administrative Template: RDP Settings (Continued)
Setting Description
In-memory bitmap cache size in
KB for 8bpp bitmaps
Specifies the size, in kilobytes, of the RAM bitmap cache to use for the 8-bits-per-pixel
color setting. If ScaleBitmapCachesByBPP is true (the default), this cache size is
multiplied by the bytes per pixel to determine the actual RAM cache size.
When this setting is enabled, enter a size kilobytes.
Bitmap caching/cache
persistence active
Determines whether persistent bitmap caching is used (active). Persistent bitmap caching
can improve performance, but it requires additional disk space.
Color depth
Specifies the color depth of the remote desktop. Select one of the available settings:
n
8 bit
n
15 bit
n
16 bit
n
24 bit
n
32 bit
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 remote desktop.
Desktop background
Determines whether the desktop background appears when clients connect to a remote
desktop.
Desktop composition
(Windows Vista or later) Determines whether desktop composition is enabled on the
remote 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.
Enable compression
Determines whether RDP data is compressed. This setting is enabled by default.
Enable RDP Auto-Reconnect
Determines whether the RDP client component attempts to reconnect to a remote desktop
after an RDP protocol connection failure. This setting has no effect if the Use secure
tunnel connection to desktop option is enabled in Horizon Administrator. This setting is
disabled by default.
Font smoothing
(Windows Vista or later) Determines whether anti-aliasing is applied to the fonts on the
remote desktop.
Menu and window animation
Determines whether animation for menus and windows is enabled when clients connect to
a remote desktop.
Redirect clipboard
Determines whether the local clipboard information is redirected when clients connect to
the remote desktop.
Redirect drives
Determines whether local disk drives are redirected when clients connect to the remote
desktop. By default, local drives are redirected.
Enabling this setting, or leaving it unconfigured, allows data on the redirected drive on the
remote desktop to be copied to the drive on the client computer. Disable this setting if
allowing data to pass from the remote desktop to users' client computers represents a
potential security risk in your deployment. Another approach is to disable folder redirection
in the remote desktop virtual machine by enabling the Microsoft Windows group policy
setting, Do not allow drive redirection.
The Redirect drives setting applies to RDP only.
