I've been playing with the options in BSPlayer and changed the resolution of the file playing which also changed the resolution of my display. When I changed it back the monitor settings had gone crazy, displaying a short fat picture. Try as I might I can't get the picture size quite right, the edges aren't straight and everything is still slightly distorted.
Does anyone know of an easy way of getting the picture centered rather than endlessly fiddling with the monitor settings? Maybe a test card for a monitor?
