I'm a newbie to widescreen televisions and have just picked up what is a very nice Aventos. Its a 32". In widescreen 16:9 setting I have fairly large black bars at the top and bottom of the screen. Is this normal? (the bars are about 1-1/2 to 2") I was hoping there would be a mode that fills the whole screen without stretching the picture too much vertically but Cine doesn't do it for me.
