Epson EB-X49 offers great performance in a remarkably versatile package. Long lamp life and trusted Epson durability offer peace of mind and minimal maintenance. Now can enjoy large-scale presentations with crisp, clear text, as well as compelling imagery and video content, on-screen sizes up to 300 inches. 3,600-lumen performance combines with a high contrast ratio of 15,000:1 to offer outstanding visual performance, even in well-lit rooms. With a lamp life and air filter maintenance cycle of 12,000 hours in eco mode, users won't need to worry about maintenance for more than 5 years. This projector has a built-in 5W speaker to allow audio content to be heard clearly, without the need for additional external speakers. Wi-Fi compatibility and network capability (via RJ45) mean the EB-X49 can be added to a company network or upgraded for wireless device access at a later stage (optional accessory required). 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.
