Using DPI Synchronization - Win user guide

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

Like the Display Scaling feature, the DPI Synchronization feature can improve the readability of text and icons on high-DPI displays. Unlike the Display Scaling feature, which increases the size of fonts and images and can make them blurry, the DPI Synchronization feature increases the size of fonts and images, keeping them sharp. For this reason, the DPI Synchronization feature is generally preferred for an optimal user experience.

If the DPI Synchronization feature and the Display Scaling feature are both enabled, only one feature takes effect at any given time.

The DPI synchronization feature is enabled by default, but a Horizon administrator can disable it.
