Despite its sleek and compact dimensions, the PT-EW730ZE produces a class-leading 7,000 lm of brightness with a contrast ratio of 5,000:1.¦Panasonic's Daylight View Basic technology achieves sharp, easy-to-see images by dearly reproducing the details in dark image areas, which were previously difficult to see in brightly lit rooms. A built-in sensor measures the ambient light, and the Daylight View Basic function adjusts the halftone color and brightness level according to the surrounding illumination.
