If you use the VLC media player to watch your videos, you probably watch them in fullscreen mode. Instead of constantly having to change the display mode everytime you launch a new video to watch, change the default to fullscreen and start enjoying your movie immediately.
1. Open VLC Media Player.
2. Go to the menu, click Tools and select Preferences.
3. When the Preferences menu appears, click the Video button to bring up the General Video Settings.
4. Check the Fullscreen checkbox.
5. Click the Save button.
