Using DPI Synchronization
The DPI Synchronization feature ensures that the DPI setting in a remote session matches the client
machine's DPI setting. When you start a new remote session, Horizon Agent sets the DPI value in the
session to match the DPI value of the client machine.
The DPI Synchronization feature cannot change the DPI setting for active remote sessions. If you
reconnect to an existing remote session, the Display Scaling feature scales the remote desktop or
application appropriately.
The DPI Synchronization feature is enabled by default. A Horizon administrator can disable the DPI
Synchronization feature by disabling the Horizon Agent DPI Synchronization group policy setting. You
must log out and log in again to make the configuration change take effect. For more information, see the
Configuring Remote Desktop Features in Horizon 7 document.
When the DPI Synchronization feature and the Display Scaling feature are both enabled, only one feature
takes effect at any given time. Display scaling occurs only when DPI synchronization has not yet taken
effect (that is, before the DPI setting on the remote desktop matches the DPI setting on the client
machine), and display scaling stops working after the DPI settings match.
For virtual desktops, the DPI Synchronization feature is supported on the following guest operating
systems:
n
32-bit or 64-bit Windows 7
n
32-bit or 64-bit Windows 8.x
n
32-bit or 64-bit Windows 10
n
Windows Server 2008 R2 configured as a desktop
n
Windows Server 2012 R2 configured as a desktop
n
Windows Server 2016 configured as a desktop
For published desktops and published applications, the DPI Synchronization feature is supported on the
following RDS hosts:
n
Windows Server 2012 R2
n
Windows Server 2016
The DPI Synchronization feature requires Horizon Agent 7.0.2 or later and Horizon Client 4.2 or later.
Note 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:

If you change the DPI setting on the client machine, you must log out and log in again to make
Horizon Client aware of the new DPI setting on the client machine. This requirement applies even if
the client machine is running Windows 10.
