Open the Application.
Open PREFERENCES from the TOOLS menu.
Toggle the Settings from SIMPLE to ALL
Find INTERFACE → MAIN INTERFACES → Qt in the left menu.
Change Maximum Volume Displayed from 125 to 200 or 300 from 125150 or maybe 200. You can go up to 300% but that is not advisable. There will be a wide range of volumes within other tools you may use and if everything is maxed and you use a louder (generally most modern) video in VLC it will be LOUD and may blow the speakers.
You must restart the app for these settings to take effect.
