The source selection menu
The picture menu - Where the picture tweaking occurs!
Sound menu - have pretty much never touched this other than setting to cinema
Channel menu - Used for the internal analogue tuner... have never touched this
Window menu - Use this to access the VGA menu (aspect ratio changing is handled by the remote button)
Other Setting menu - Just for setting OSD positioning/colour and whether a blue screen is shown when a bad signal is sent to the tv (or it just stays as static)
VGA Window menu - I have never touched the settings in here, rather leaving it to the Auto Adjust (detailed earlier)
