If you use the VMware Blast display protocol or the PCoIP display protocol, Horizon Client supports high resolutions for client systems that support Retina Display. After you connect to a remote desktop, you can select the Connection > Resolution > Full Resolution menu item to enable a high-resolution mode. This menu item appears only if the client system supports Retina Display.

In high-resolution mode, the DPI Synchronization feature ensures that the remote desktop's DPI setting matches the client system's DPI setting. For more information, see Using DPI Synchronization.
