Panasonic PTVX500U LCD Projector Panasonic's Daylight View Basic technology achieves sharp, easy-to-see images by clearly 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. The quiet design keeps noise levels down to 29 dB,*7 so the sound of the cooling fan is hardly noticeable.
