Presentations become effortless, with the sharp, stylish EB-X39, which offers great performance in remarkably versatile package. Long lamp life and trusted Epson durability offer peace of mind and minimal maintenance. Enjoy large scale presentations with crisp, clear text, as well as compelling imagery and video content, on screen sizes up to 300 inches. 3,500-lumen performance combines with a high contrast ratio of 15,000:1 to offer outstanding visual performance, even in well-lit rooms. Automatic vertical and manual horizontal keystone correction provide greater flexibility as to where the projector can be placed in the room for distortion-free images and the wide optical zoom adds to the flexibility. This projector has a built-in 5W speaker to allow audio content to be heard clearly, without the need for additional external speakers. With a lamp life and air filter maintence cycle of 12,000 hours in eco mode, users won't need to worry about maintenance for more than 5 years. Wi-Fi compatibility and network capability (via RJ45) mean the EB-X39 can be added to a company network or upgraded for wireless device access at a later stage (optional accessory required).
