Our Verdict

LG CineBeam Q

Epson EpiqVision Mini EF21

The LG CineBeam Q is better than the Epson EpiqVision Mini EF21. The LG is even more portable due to its smaller size and integrated handle. While it's a bit dimmer than the Epson, it makes up for it with far superior contrast, making it look much better in dark rooms. Neither projector is a good option for gaming, but if forced against a wall, the LG has slightly faster input lag due to the inclusion of a Game Mode.
