The MC-WU5501 combines WUXGA 1920 x 1200 resolution with super-bright 5,200 ANSI lumens white/color light output for a remarkable visual achievement as part of Maxell's Collegiate Series. Classrooms, lecture halls, and auditoriums may all be transformed into actual learning centres. The MC-WU5501 is stackable, allowing you to stack two projectors on top of each other to project the same image onto a screen for increased brightness.
