MMR is not supported on all versions of Windows clients and virtual desktops. To find out whether this
feature is supported on a particular type of client, see the feature support matrix included in the "Using
VMware Horizon View Client" document for the specific type of desktop or mobile client device. Go to
https://www.vmware.com/support/viewclients/doc/viewclients_pubs.html.
Using Single Sign-On for Logging In to a View Desktop
The single-sign-on (SSO) feature allows you to configure View Manager so that end users are prompted to log
in only once.
If you do not use the single-sign-on feature, end users must log in twice. They are first prompted to log in to
View Connection Server and then are prompted log in to their View desktop. If smart cards are also used, end
users must sign in three times because users must also log in when the smart card reader prompts them for a
PIN.
For View desktops, this feature includes the Graphical Identification and Authentication (GINA) dynamic-link
library for Windows XP and a credential provider dynamic-link library for Windows Vista, Windows 7, and
Windows 8.
Using Multiple Monitors with a View Desktop
Regardless of the display protocol, you can use multiple monitors with a View desktop.
If you use PCoIP, the display protocol from VMware, you can adjust the display resolution and rotation
separately for each monitor. PCoIP allows a true multiple-monitor session rather than a span mode session.
A span mode remote session is actually a single-monitor session. The monitors must be the same size and
resolution, and the monitor layout must fit within a bounding box. If you maximize an application window,
the window spans across all monitors. Microsoft RDP 6 uses span mode.
In a true multiple-monitor session, monitors can have different resolutions and sizes, and a monitor can be
pivoted. If you maximize an application window, the window expands to the full screen of only the monitor
that contains it.
This feature has the following limitations:
n
If you use PCoIP, the maximum number of monitors that you can use to display a View desktop is 4. When
3D feature is enabled, up to 2 monitors are supported with a resolution of up to 1920 X 1200. Pivoted
monitors are supported, but stacked monitors are not.
n
If you use Microsoft RDP 7, the maximum number of monitors that you can use to display a View desktop
is 16.
n
If you use Microsoft RDP display protocol, you must have Microsoft Remote Desktop Connection (RDC)
6.0 or higher installed in the View desktop.
n
If you use a View desktop in local mode, no remote display protocol is used. You can use up to 2 monitors
in span mode.
