I have just set up my first PJ, its a Sanyo PLV30 projecting onto an owl electric screen, with a PAL progressive scan player. Fantastic results straight out of the box. But I am wondering with all the settings for Croma, sharpness etc on the Player and similar on the projector. How do you get the best image, which unit should take presidence on set up? Need to start fiddling now or should I leave it as it is? I have read about set up discs, so I will probably get one of those.
