Brand new, factory-sealed original DLP projector. An excellent choice for home cinema. Lamp operating hours: 0 (since it is completely new). DLP technology is excellent for projectors because it delivers sharp, high-contrast images with smooth motion and great reliability. DLP projectors are better than LCD models because they deliver sharper images, higher contrast, more reliable color accuracy, and require less maintenance over time. - Maximum resolution: 3840 × 2160 (4K UHD) - Native resolution: 3840 × 2160 px The native resolution indicates the number of pixels the projector can display horizontally and vertically.
