An administrator can hide the display scaling seing (both the Options menu item and the Seings window
check box) by enabling the Horizon Client Locked Guest Size group policy seing. Enabling the Locked
Guest Size group policy seing does not disable the DPI Synchronization feature. To disable the DPI
Synchronization feature, an administrator must disable the DPI Synchronization group policy seing. For
more information, see “Using DPI Synchronization,” on page 78.
In a multiple-monitor setup, using display scaling does not aect the number of monitors and the maximum
resolutions that Horizon Client supports. When display scaling is allowed and in eect, scaling is based on
the DPI seing of the primary monitor.
Using DPI Synchronization
The DPI Synchronization feature ensures that the remote desktop's DPI seing matches the client machine's
DPI seing for new remote sessions. When you start a new session, Horizon Agent sets the DPI value in the
remote desktop to match the DPI value of the client machine.
The DPI Synchronization feature cannot change the DPI seing for active remote sessions. If you reconnect
to an existing remote session, the Display Scaling feature (if enabled) scales the remote desktop or
application appropriately.
The DPI Synchronization feature is enabled by default. An administrator can disable the DPI
Synchronization feature by disabling the Horizon Agent DPI Synchronization group policy seing. You
must log o and log in again to make the conguration change take eect. For more information, see
"Horizon Agent Conguration ADM Template Seings" in the Seing Up Desktop and Application Pools in
View document.
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 o 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 o 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 o and log in again to make the new seing take eect.
