The Epson EB-1780W projector is based on 3-chip LCD technology for amazing colour, incredible detail and solid reliability. 3LCD's 3-chip architecture dedicates an entire chip to process each primary colour - red, green and blue, continuously. Unlike single-chip technology that delivers colour sequentially, you get full-time colour. The result is vibrant, realistic images and video all delivered with 3LCD's true-to-life colour.With brightness up to 3,000 lumens the screen is easily viewed from anywhere in the room, even without dimming the lights. Even though its light weight and compact size enable it to be carried from room to room, the projector is capable of highly visible images thanks to its high brightness and superior 10,000:1 contrast ratio.The 1780W features WXGA resolution delivering high quality images and crisp, sharp text without any distortion. This applies to video output devices such as PCs and smart devices with their ever increasing image quality and higher definition.
