I use 680 432 30hz interlaced, I have gotten into the service menu of the TV and got the Vertical hieght of the screen perfect, just he horizontal needs to be adjusted now. I have been getting support from other BYoAc'ers and it is just a matter of working with the settings in the service menu........we shall see how that works out, worst case I just deal with losing two inches on the sides, othwise it looks and plays great..
