By modulating the laser power, the BenQ LH820ST has a dynamic contrast ratio of 3,000,000:1. The BenQ LH820ST can produce darkish blacks, but only so far. The LH820ST’s high lumens output works against this projector’s ability to deliver deep blacks with dark area detail. Turning the light source output down by putting the projector in ECO mode and tweaking the brightness and contrast helps achieve darker blacks, but only so much, and crushes the blacks. I don’t think sacrificing shadow details is worth the modest increase in black performance for movies and TV content.
