The UM351W is ultra short throw with a widescreen resolution which is ideal for classrooms. The WXGA resolution is widescreen will project a sharp, crisp image, showing your image in good detail. It is suitable for PowerPoint, images, video clips and long videos. With widescreen you will get 30% more viewing area than the standard XGA resolution and when you watch videos your pixels will not be stretched. Short throw is beneficial because teachers will be able to stand to the side of the projector, casting no shadows on the screen and there will be no glare in the presenter’s eyes. It is also great if you are limited on space. 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 54cm away (the wall mount kit comes supplied as standard). The high 3500 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 UM351W being short throw. 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 powerful (enough to fill a small to medium sized room), and means you wouldn’t need to purchase any additional speakers. 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.
