The Acer K137i is a portable LED projector. With the native widescreen resolution you will be able to match the quality that is on laptops and therefore granting you a sharp and crisp image. The 30,000 hour lamp life will be sure to last you a very long time. The K137i is not a bright projector with only 700 lumens, so you will have to project with lights completely off. It isn’t suitable for a large or medium sized audience as it is not powerful enough; perhaps being more suited for personal use. Maybe watching video at home on a larger display. It offers a contrast ratio of 10,000:1, meaning it will give your darker areas more depth and appear more defined. The K137i has the modern HDMI connection so you will be able to connect to modern sources. This is an ideal portable projector with it only being 0.51KGs, it comes with a carry case and has a built in 3W speaker for added audio. This will give you more freedom in where you can project.
