User manual

To enable or disable the secure tunnel, in View Administrator, go to the Edit View Connection Server
Settings dialog box and use the check box called Use secure tunnel connection to desktop.
n
Verify that a desktop or application pool has been created and that the user account that you plan to use
is entitled to access the pool. For Connection Server 5.3.x, see the topics about creating desktop pools in
the View Administration document. For Connection Server 6.0 and later, see the topics about creating
desktop and application pools in the Setting Up Desktop and Application Pools in View document.
IMPORTANT If end users have a high-resolution display and will use the High Resolution Mode client
setting while viewing their remote desktops in full screen mode, you must allocate sufficient VRAM for
each Windows 7 or later remote desktop. The amount of vRAM depends on the number of monitors
configured for end users and on the display resolution. To estimate the amount of vRAM you need, see
the section "RAM Sizing for Specific Monitor Configurations" of the topic "Estimating Memory
Requirements for Virtual Desktops," in the View Architecture Planning document.
n
To use two-factor authentication with Horizon Client, such as RSA SecurID or RADIUS authentication,
you must enable this feature on Connection Server. For more information, see the topics about two-
factor authentication in the View Administration document.
Configure VMware Blast Options
You can configure decoding and network protocol options for remote desktop and application sessions that
use the VMware Blast display protocol.
H.264 decoding has the following restrictions:
n
Multiple monitors are not supported.
n
The maximum resolution that is supported depends on the capability of the graphical processing unit
(GPU) on the client. A GPU that can support 4K resolution for JPEG/PNG might not be able to support
4K resolution for H.264. If a resolution for H.264 is not supported, Horizon Client uses JPEG/PNG
instead.
Prerequisites
This feature requires Horizon Agent 7.0 or later.
Procedure
1 In the desktop and application selector window of Horizon Client, click the Settings icon in the upper-
right portion of the window, and select VMware Blast in the left pane of the Settings window.
2 Configure the decoding and network protocol options.
Option Description
H.264
Select this option to allow H.264 decoding in Horizon Client. When this
option is selected (the default setting), Horizon Client uses H.264 decoding
if the agent supports H.264 software encoding. If the agent does not
support H.264 software encoding, Horizon Client uses JPG/PNG decoding.
Deselect this option to always use JPG/PNG decoding.
UDP
Select this option to allow UDP networking in Horizon Client. When this
option is selected (the default setting), Horizon Client uses UDP
networking if UDP connectivity is available. If UDP networking is blocked,
Horizon Client uses TCP networking.
Deselect this option to always use TCP networking.
NOTE UDP is disabled by default on a Horizon remote desktop. For UDP
to work, it must be enabled on the desktop, the client, and the Blast Secure
Gateway (BSG).
Your changes take effect the next time a user connects to a remote desktop or application and selects the
VMware Blast display protocol. Your changes do not affect existing VMware Blast sessions.
