Projection technology	DLP
Projector native resolution	UHD 4K (3840x2160)
Contrast ratio (typical) The difference in light intensity between the brightest white and the darkest black.	1200000:1
Native aspect ratio The aspect ratio is the ratio of the width of an image to its height. The native aspect ratio is the one which the projector/display is particularly designed for. Images shown in native aspect ratio will utilize the entire resolution of the display and achieve maximum brightness. Images shown in other than native aspect ratio will always have less resolution and less brightness than images shown in native aspect ratio.	16:9
