Users that have poor eyesight or high-resolution screens, such as 4K monitors, generally have scaling enabled by setting the DPI (Dots Per Inch) on the client system to greater than 100 percent. The DPI setting controls the size of the text, apps, and icons. A lower DPI setting makes them appear smaller and a higher setting makes them appear bigger. With the Display Scaling feature, remote desktops support the client machine's scaling setting and appear normal-sized rather than very small.
Note: The DPI Scaling feature is not supported on Raspberry Pi devices and does not work with published applications.
In a multiple-monitor setup, using display scaling does not affect the number of monitors and the maximum resolutions that Horizon Client supports. When display scaling is allowed and is in effect, scaling is based on the DPI setting of the system.
