The NEC UM301Xi is an interactive and ultra short throw projector which is ideal for classrooms. It is an interactive multi-pen projector and is shipped with 2 pens so you can engage your audience with an interactive whiteboard. The projector mounts above the board or screen and projects a wide image from very close – for example you can get a 1.5 m wide image from only 54 cm away (the wall mount kit comes supplied as standard). This is beneficial because teachers will be able to stand audience side of the projector, casting no shadow on the screen and being able to engage with the students better. In addition, the teacher will get no glare from having to look into the lens of the projector. With XGA resolution, the UM301Xi will project a sharp, crisp image, showing presentations and spreadsheets in good detail. It is suitable for PowerPoint, images and short video clips. Widescreen projectors are recommended for long movies. However, you will get a sharp image when connecting to a computer with the UM301Xi. One of the strengths of this projector is the range of inputs which includes two HDMI, VGA, and USB meaning you can connect more than one device at the same time. There are two USB ports and you can present PC-free via a USB stick. There is also a microphone input too. A built in 20W speaker is surprisingly powerful (enough to fill a small to medium sized room), and means you wouldn’t need to purchase any additional speakers. The 3000 lumens means that you can present with the lights on and blinds open at anytime of the day and still get a bright image. You will not lose any brightness due to the UM301Xi being short throw. NEC focus on their Eco friendliness and this unit has some good features to keep the running costs down including an off timer which will switch off the projector if no source is connected after a certain amount of time and many more. Overall, this is a reliable, user friendly projector perfect for classroom use and has many features.
