NOTE: Native and VST plugin GUIs can also be rescaled as described below. GUI up-scaling is intended for use with high resolution displays. These settings allow you to rescale FL Studio's vectorial Graphical User Interface (GUI), including separate options for pop-ups, menus and the cursor. The General Settings page contains various general settings of the working environment in FL Studio.
To open the General Settings choose ' Options > General settings' from the main menu or press the F10 function key on your keyboard.
