Placement tips: ceiling mount needs the distance PLUS lens-offset (most home projectors shift the image upward ~10% of screen height); keystone correction costs resolution — use lens shift when available. UST (0.25) sits ~25cm from the wall for 100", ideal for living rooms, but demands an ALR screen for daytime viewing.
