An administrator can use the Save resolution and DPI to server group policy setting to save these settings to the server so that they are always applied, regardless of the client device that you use to log in to the remote desktop. By default, custom display resolution and display scaling settings are stored only on the local client system.This feature has the following limitations and considerations. Display scaling, which is represented as a percentage, increases or decreases the size of text, icons, and navigation elements. At higher resolutions, such as 1600 x 1200 pixels, items appear sharper.
The display resolution determines the clarity of the text and images. You can use Horizon Client to customize the display resolution and display scaling for a remote desktop.
