With a 2,500 ANSI lumen light output and a contrast ratio of 2,500:1, the Hitachi CP-DX250 XGA 2500 Lumens DLP Projector displays vibrant high-resolution images with deeper black levels and clear text. An HDMI port allows for a single-cable connection to high-definition A/V devices. With a high contrast ratio of 2,500:1, both dark and bright scenes are produced in their true form. And thanks to the combination of Intelligent Eco Mode and ImageCare technology, this classroom-friendly CP-DX250 projector offers optimal picture performance with energy savings. A wall color correction feature rectifies the color of images projected onto non-white surfaces. This DLP projector is 3D capable, but 3D glasses and a special graphics card are required for 3D viewing and are not included with the projector.
