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.

To enable high-resolution mode for a remote desktop, connect to the remote desktop and select Connection > Use Full Resolution for Retina Display from the menu bar.

To enable high-resolution mode for published applications, click the Settings button (gear icon) in the upper-right corner of the desktop and application selector window, click Applications in the left pane, click the Display tab, and select the Use Full Resolution for Retina Display check box.

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