Using DPI Synchronization

The DPI Synchronization feature ensures that the DPI setting in a remote desktop matches the client system's DPI setting.

The DPI Synchronization feature has the following requirements.

• The client system must support Retina Display.
• Full-resolution mode (Connection > Resolution > Full Resolution) must be selected in the remote desktop.
• If you use multiple monitors, the Retina Display must be the primary window in system preferences. You cannot have more than one display in full-screen mode.

A Horizon administrator can disable the DPI synchronization feature.

If DPI synchronization is disabled, display scaling is used. The Display Scaling feature scales the remote desktop appropriately.

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.
• If you connect to an active remote session in full-resolution mode, Horizon Client scales the resolution to be similar to when DPI Synchronization is enabled, but icons are not as clear. If you switch from normal to full-resolution mode in an active remote session, Horizon Client prompts you to log off from the remote session for the resolution change to take effect.
• If you use a non-Retina Display computer when you start a remote session, and then use a Retina Display computer to connect to the same session, the remote session cannot change to the new DPI setting until after you log off.
