always be used on this Host. Note also that the use of the kernel-mode screen capture
driver will result in Aero Glass effects being disabled on Hosts running Windows 7.
The user can further specify that the kernel-mode screen capture driver be preloaded at
Host startup time by clicking on the checkbox next to Attach kernel-mode mirror
display driver at Host startup; otherwise, the mirror driver will be attached and
unattached with each connection to the Host, which may be disruptive for the user.
User-mode Screen Capture
The user-mode screen capture driver is the default option to capture the remote desktop
for all supported platforms. It runs as 32-bit x86 user mode code, but can capture either
x86 or x64 systems, and is the only supported screen capture technology for Terminal
Services sessions.
Note: The user can check the Allow use of kernel-mode screen capture, which will
disable Aero Glass option with the user-mode screen capture driver. By checking this
option, the user allows Gateway connections to use kernel-mode screen capture. This
might be useful for making screen recordings while a different user has remote access to
the desktop.
When user-mode screen capture is selected, the amount of bandwidth used to capture
and transmit remote desktop screen can be restricted or "throttled" by reconfiguring a
user-mode screen capture profile. The default profile is "High Quality/High Bandwidth"
but other profiles corresponding to smaller bandwidth limits are available. See
"Bandwidth throttling" for more information.
The Screen tab indicates which user-mode screen capture profile is applicable.
Bandwidth throttling
The user-mode screen capture technology has the ability to "throttle" itself to a restricted
amount of bandwidth. This may be preferable when responsiveness and throughput are
more important than screen quality, particularly over low-bandwidth connections.
The amount of throttling is controlled by parameters set in a "user-mode screen capture
profile". The “Configure…” button on the Screen tab brings up a dialog that allows the
end-user to select a hard-coded, predefined configuration, or to specify a custom
configuration.
