This value is normally given in the source specifications. If not, adjust until full image is displayed (no missing pixels). • Vertical start in lines : number of lines between the start of the input signal and start of the image on the screen. • Height = Active vertical lines : number of horizontal lines determining the height of the projected image. this value is normally given in the specification of the source. If not, adjust until full image height is displayed (no missing lines). • Total pixels: Total horizontal pixels in the source. If the value is wrong, sampling mistakes (small vertical bars in the projected image) will be seen in the image. • Total lines: Total vertical lines in the source. How to start up? 1.
