If form is not scaled automatically, be sure that forms ClientHeight and ClientWidth properties are specified in the Dfm fileĢ. If form is not scaled automatically, then set the TForm.PixelsPerInch property to 96
The ParentFont property of the Form must be False. The TForm.Position property must be not poDefault, because size of form will not be scaled in this case. Project options / Application / 'Enable High-DPI' or 'DPI Awareness' options must be enabled. This mode is recommended to use with Embarcadero RAD Studio 10.2 Tokio and newer. Use this mode if you wish to have automatic 'per monitor' support of current system DPI.
