The DPI Synchronization feature ensures that the DPI setting in a remote desktop or published application matches the client system's DPI setting.
If DPI synchronization is disabled, display scaling is used. The Display Scaling feature scales the remote desktop or published application appropriately.
If you want to set the resolution manually, you might be able to enable the High Resolution Mode setting. For information, see Setting the Screen Resolution.
The DPI Synchronization agent group policy setting determines whether the DPI Synchronization feature is enabled. The feature is enabled by default. With DPI Synchronization, the DPI value in the remote session changes to match the DPI value of the client machine when you connect to a remote desktop or published application.
If the DPI Synchronization Per Connection agent group policy setting is enabled in addition to the DPI Synchronization group policy setting, DPI Synchronization is supported when you reconnect to a remote desktop. This feature is disabled by default.
For more information about the DPI Synchronization and DPI Synchronization Per Connection group policy settings, see the Configuring Remote Desktop Features in Horizon document.

Following are tips for using the DPI Synchronization feature.
- If you change the DPI setting on the client system, but the DPI setting does not change in the remote desktop, you might need to log out and log in again to make Horizon Client aware of the new DPI setting on the client system.
- 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 might need to 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.
- Although Windows 10 systems support different DPI settings on different monitors, the DPI Synchronization feature uses the DPI value that is set on the client system's monitor in which the web browser used for launching the HTML Access client session is located. HTML Access does not support different DPI settings in different monitors.
- To sync up with another monitor that has a different DPI setting, you must log out of the remote desktop or published application, drag the web browser used for launching the HTML Access client session to the other monitor, and log back in to the remote desktop or published application to make the DPI settings match between the client system and remote desktop or published application.
