QPT-210 is a projector with a high brightness, designed for teaching or business purpose: the high brightness of 4,000 lumens ensures that even in a brightly lit room the projected images would still be clear, providing users the best visual experience. The overall look is stylish and elegant. The white upper cover receives polishing processing while black matted surface is applied on the sides. The smooth lines contouring the body deliver a sense of outstanding taste. The ventilation system helps reduce significant not only the temperature but also the noise level to 25 decibels, thus keeping users from being disturbed in using it.
