The DPI Synchronization feature ensures that the DPI (dots per inch) setting in a remote desktop or published application matches the client machine's DPI setting.
When you start a new remote desktop or published application, Horizon Agent sets the DPI value in the remote session to match the DPI value of the client machine. The DPI Synchronization feature cannot change the DPI setting for active remote sessions.
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 published 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 4.7 or later. The DPI Synchronization feature is not available if you use Horizon Client 4.7 with Horizon Agent 7.0 or 7.0.1, or an earlier (pre-4.7) version of Horizon Client with Horizon Agent 7.0.2 or later.
The DPI Synchronization feature is controlled by the Allow display scaling option, which is turned on by default. You can turn off this option and manually adjust the resolution. For information, see Adjust the Screen Resolution for Remote Desktops and Published Applications.
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.
