User manual

When the DPI Synchronization feature and the Display Scaling feature are both enabled, only one feature
takes eect at any given time. Display scaling occurs only when DPI synchronization has not yet taken eect
(that is, before the DPI seing on the remote desktop matches the DPI seing on the client machine), and
display scaling stops working after the DPI seings match.
The DPI Synchronization feature requires Windows 7 or later for single-session desktops, Windows Server
2008 R2 or later for session-based desktops and applications on RDS hosts, Horizon Agent 7.0.2 or later, and
Horizon Client 4.2 or later.
N The DPI Synchronization feature is not available if you use Horizon Client 4.2 with Horizon Agent
7.0 or 7.0.1, or Horizon Client 4.0 or 4.1 with Horizon Agent 7.0.2 or later. Only the Display Scaling feature is
available in these scenarios.
Following are tips for using the DPI Synchronization feature:
n
If you change the DPI seing on the client machine, you must log out and log in again to make
Horizon Client aware of the new DPI seing on the client machine. This requirement applies even if the
client machine is running Windows 10.
n
If you start a remote session on a client machine that has a DPI seing of more than 100 percent, and
then use the same session on another client machine that has a dierent DPI seing of more than 100
percent, you must log out and log back in to the session on the second client machine to make DPI
synchronization work on the second client machine.
n
Although Windows 10 and Windows 8.x machines support dierent DPI seings on dierent monitors,
the DPI Synchronization feature uses only the DPI value that is set on the client machine's primary
monitor. All monitors in the remote desktop also use the same DPI seing as the client machine's
primary monitor. Horizon Client does not support dierent DPI seings in dierent monitors.
n
If an administrator changes the DPI Synchronization group policy seing value for Horizon Agent,
you must log out and log in again to make the new seing take eect.
n
When you connect a laptop that supports dierent DPI seings on dierent monitors to an external
monitor, and you set the external monitor to be the primary monitor, Windows automatically changes
the primary monitor and primary monitor DPI seing every time you detach or reaach the external
monitor. In this situation, you must log out and log back in to the client system to make Horizon Client
aware of the primary monitor change, and you must log out and log back in to the remote desktop or
application to make the DPI seings match between the client system and remote desktop or
application.
Change the Display Mode While a Desktop Window Is Open
You can change display modes, such as from All Monitors mode to Fullscreen mode, without having to
disconnect from a remote desktop.
This feature is not supported for remote applications.
Prerequisites
Verify that you are using VMware Blast display protocol or the PCoIP display protocol.
Procedure
1 On the client system, in the notication area (system tray), right-click the Horizon Client icon and select
the option to open the Seings window.
N You can also open the Seings window from the application and desktop selection window.
2 Select the remote desktop and select a display option.
