Our Verdict

LG CineBeam Q

LG CineBeam S

The LG CineBeam Q and the LG CineBeam S perform very similarly. The main difference between the two is that the CineBeam Q is a short-throw projector with ARC support, while the CineBeam S is an ultra-short-throw projector that supports eARC. Otherwise, both projectors have impressive contrast, wide color gamuts, and are very accurate after calibration. On the other hand, both have disappointing brightness and high input lag for gamers.
