The DPI Synchronization feature ensures that the DPI setting in a remote desktop or published application matches the client system's DPI setting. When you start a new remote session, Horizon Agent sets the DPI value in the remote session to match the DPI value of the client system.
The DPI synchronization feature is not supported on Raspberry Pi devices.
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 appropriately.
The DPI Synchronization feature is enabled by default. A Horizon administrator can disable the DPI Synchronization feature by disabling the DPI Synchronization agent group policy setting. You must log out and log in again to make the configuration change take effect. For information about the DPI Synchronization group policy setting, 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 system), 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.
32-bit or 64-bit Windows 7
32-bit or 64-bit Windows 8.x
32-bit or 64-bit Windows 10
Windows Server 2008 R2 configured as a desktop
Windows Server 2012 R2 configured as a desktop
Windows Server 2016 configured as a desktop
For published desktops and applications, the DPI Synchronization feature is supported on the following RDS hosts.
Windows Server 2012 R2
Windows Server 2016
The DPI Synchronization feature requires Horizon Agent 7.0.2 or later and Horizon Client 4.9 or later.
Following are tips for using the DPI Synchronization feature.
If you start a remote session on a client system that has a DPI setting of more than 100 percent, and then use the same session on another client system that has a different DPI setting of more than 100 percent, you must log out and log back in to the remote session on the second client system to make DPI synchronization work on the second client system.
If a Horizon administrator changes the DPI Synchronization group policy setting value for Horizon Agent, you must log out and log in again to make the new setting take effect.
